A concave selenizone runs well above the midwhorl but somewhat below the most adapical line of the whorl; the belt between the selenizone and the impressed (upper) suture is rather wide and mostly convex but a narrow concave band accompanies the suture. The suture follows the periphery of the former whorl. + +The ornament is poorly preserved but the coarser elements are observable. Subregularly repeated, unequally strong riblets are visible in the belt between the selenizone and the adapical suture. Their shape is almost straight in slightly prosocline orientation with a short prosocyrt part along the selenizone. Weaker riblets or thick growth lines seem to be developed also on the outer whorl face occasionally. Two cords, the strongest spiral ornamental elements, limit the selenizone. At the first third of the distance toward the adapical suture from the selenizone, single marked spiral thread is visible and two weak threads are also present between the aforesaid one and the cord along the selenizone. Between the strongest spiral thread on the ramp and the selenizone, the collabral riblets weaken; nodules are at crossings with the riblets. The outer face is covered by dense spiral threads of unequal strength, crossed only by strongly prosocyrt growth-lines, which are visible only in few spots.

The ramp is flattish but slightly convex just below the suture; its abapical rim is concave along the selenizone. The selenizone itself is moderately wide, concave between two sharp spiral cords; the abapical one just coincides with angulation of the whorl surface. The outer face is rather wide and its surface is nearly parallel to the axis but having also a feebly concave median belt. Its lower edge is slightly swollen next the rounded-angular periphery. The suture follows the abapically first spiral ridge from the peripheral one. The base is subglobular with convex wall, and it is seemingly anomphalous or possibly narrowly phaneromphalous. No peristome part can be observed in the available specimens; the growth lines indicate a prosocline outer lip with a rather deep sinus at the height of the inferred exhalant slit. + + +Collabral riblets and spiral threads intersect each other with granules on the ramp and the riblets weaken towards the selenizone. The shape of the spiral threads gradually changes into quirinii +type +ridges on the outer face in abaxial direction; only the latter ones are observed on the base. Instead of riblets, collabral threads are present on the outer face. Seemingly, they are continued also on the base but there the threads are actually composed of short riblets between pairs of the quirinii +type +ridges and are aligned as apparently continuous collabral threads; they are most conspicuous at the periphery. The selenizone bears dense lunulae. + + +Remarks +– Both specimens are fragments of gradate shells of similar size; the inner mould one shows the conoidal-gradate outline. Though their size suggests early ontogenetic stage, the sharp angulation of the whorls and the dense lunulae seem to indicate nearly full-grown shells. The available information about the shell is satisfactory for the distinction of this species. + + +The shell fragments are most similar to + +Foveolaria hierlatzensis +( +Szabó, 2009 +) + +but its larger shells are without angulation in the growth stage where the size is similar to that of + +Foveolaria kocsisi + +n. sp. +; the position and morphology of the selenizone, and the ramp are also different.

A rather wide selenizone is blunting the adapical angulation at the abapical rim of the ramp, and the flat-convex outer face almost fully hides also the second angulation at the outer rim of the base but the strongest spiral cord somewhat highlights it and gives the periphery. On the earlier whorl, this angulation is still clearly visible above the suture, which is impressed. The base itself is subglobular with a strongly convex wall and a rather broad phaneromphalus. + + +The ornament of the ramp on the last whorl in the available specimen consists of marked collabral riblets, which are equally strong along their full length and thin, dense spiral threads. Regularly repeating lunulae are present in the selenizone between strong boundary threads. Few (4) marked spiral threads are visible on the outer face; their strength increases and their interspaces widen in abapical direction. The strongest thread provides the periphery and the outer rim of the base; the suture is positioned slightly adaxially from this thread. The outer face is crossed by thin collabral threads, vanishing within the abaxial belt of the base; tiny granules are in the intersections. Quirinii +type +ridges cover the base.

Base as whole subconoidal, its wall convex;?narrowly phaneromphalous. Selenizone rather narrow, concave and bordered by two threads above midwhorl on latest whorls. Ornament of spiral threads above selenizone, crossed by collabral threads with granules at intersecting points. Sparse, asymmetrical, weak spiral ridges below selenizone and on base. Growth lines fine, prosocyrt and just gently prosocline above and below selenizone on whorls, feebly opisthocline on base with shallow opisthocyrt part abaxially. Selenizone with sparse lunulae on early whorls, with growth lines only on last whorl. + + +Description +– A high turbiniform, very thin walled shell represents the species. It is composed of slightly convex whorls, which are separated by a slightly impressed, almost flush suture. The earliest preserved whorls are rounded-angular at both sides of the suture but the last whorl turns into the base without angulation along a wide, even arch. The spire whorls are slightly convex and there is no angulation on their surface but the belt between the selenizone and the adapical suture becomes feebly concave on the last whorl; actually a concave ramp develops. Along the abapical boundary of the ramp, which coincides with the abapical rim of the selenizone, an angulation with the outer face is just observable. The selenizone itself seems flat on the early whorls but concave on the last one; its width is rather narrow, about 12% of the sutures distance on the penultimate whorl. The outer face itself is wider than the ramp and has flat surface that bends into the base along a wide, unbroken arch. The base is convex, subconoidal as a whole and it has convex wall that evenly turns into an axial deepening. Its matrix infilling seems to hide a narrow umbilicus. The selenizone is narrow, concave and two threads border it well above the midwhorl on all preserved whorls. + + +Several equally spaced spiral threads ornament the whole surface adapically from the selenizone that are crossed by collabral threads and granules are at their intersecting points. Towards the last whorl, the number of the growth lines increases. Sparse, asymmetrical, weak spiral ridges, belonging to the +type +which has been first observed in + +Wortheniopsis quirinii +(Stoppani, 1858) + +, see in +KITTL (1899 +, p. 14, +Fig. 2 +.), ornament the whorls below the selenizone and on the base. Lunulae are present on the selenizone of the early whorls but they are missing on the last whorl. The growth lines are very fine and have a peculiar arrangement; they are prosocyrt and just gently prosocline above and below the selenizone on the whorls and feebly opisthocline on the base with a shallow opisthocyrt part on the abaxial half of the base. + + + + +Remarks +– The only specimen of + +Wortheniopsis rakusi + +n. sp. +is exceptionally well preserved compared to the +syntypes +of the Middle Triassic type species.

Earliest shell parts unknown. Suture variably impressed. Surface of early whorls evenly arched, later whorls having obscure spiral angulation adapically from midwhorl. Flat to concave ramp between upper suture and angulation. Flat or feebly concave selenizone between two spiral threads, abapical one just overlapping ridge of angulation. Feebly concave to feebly convex outer face, being wider than ramp. Transition from outer face to base widely and evenly arched. Base subglobose as whole with convex wall, anomphalous or narrowly phaneromphalous. Aperture rounded with angle at terminus of suture. Thin, smooth shell layer representing parietal lip; columellar/umbilical lip vertical, thin or weakly thickened. Ornament of spiral and collabral threads and granules on whorls, threadlike spiral ridges of asymmetric triangle cross-section on base and on outer face (quirinii +type +ridges). Growth lines feebly prosocline and fairly prosocyrt on both sides of selenizone, respectively, feebly opisthocline and opisthocyrt on base. + + +Remarks +– All +syntypes +of + +Wortheniopsis margarethae + +are of very poor preservation, therefore the nature of the exhalant system, critical for classification, has remained debatable for the recently active researchers of the Triassic gastropods. The original descriptions and drawings do not provide satisfactory help to see doubtlessly if the type species has a slit and selenizone or only peristomal sinus and sinuszone on the whorls. Therefore a re-study of the specimens has become necessary for further discussion. + + +The restudy of the +syntypes +( +NHMV 1969 +/1103) has confirmed, as their figures ( +KITTL 1894 +, Pl. +VI +, +Figs 1–3 +) also show, that even the best preserved +syntype +of the type species bears only very small pieces of badly worn shell fragments on inner mould and their outermost layer is lacking. Actually, the lines of the ornament are much more obscure than the drawings show them. A narrow, smooth and flattish ribbon between two eroded spiral threads represents the anal fasciole just adapically from an obscure angulation of the whorl surface, aligned to the abapical spiral thread. Some distinct lines of KITTL’s drawing (1894, Pl. +VI +, +Fig. 2 +) show that the growth lines of the subsutural ramp and those of the outer face form a sharp angle at the ridge of the obscure angulation i.e. at the abapical spiral thread. Actually, those few lines that cross the belt between the two spiral threads are straight linear damages and are not aligned to the growth-lines. Waste majority of the collabral lines terminate at or before reaching the two spiral threads, limiting the smooth belt that must be therefore a selenizone. The selenizone is smooth like in the latest growth phases of the two new Jurassic species. + + +Similarly to + +Pleurotomaria margarethae + +, + +Turbo quirinii +Stoppani, 1858 + +and + +Turbo funiculatus +Stoppani, 1858 + +occurred in the same formation, the Marmolada Limestone (Ladinian, Middle Triassic). First +MARIANI (1896) +then +KITTL (1899) +regarded these species also as + +Wortheniopsis + +. The latter author has also unified the two latter species, however, as +KITTL (1899 +, Pl. 14–15) figures show it, the interpretation of this species involves so significantly different morphologies that it might belong to two species. + + +According +to unpublished data of +S. Monari +(Padua University), slitless, sinuszone bearing gastropod with morphology similar to the +type +species of + +Wortheniopsis + +occurs in the fauna of the Marmolada Limestone ( +MONARI +, pers. comm.). + + +The Late Triassic + +Wortheniopsis budensis +Kutassy, 1927 + +, in lack of any traces of the exhalant system, is excluded from the comparisons. The name + +Wortheniopsis + +has also been applied to some Palaeozoic forms but their revision is out of the scope of this paper. + + +The emended diagnosis above is based on the study of the +syntypes +of the type species, + +Pleurotomaria margarethae +Kittl, 1894 + +and monotypes of two new Jurassic species, + +Wortheniopsis rakusi + +n. sp. +and + +Wortheniopsis bakonyensis + +n. sp. +The morphology of these three species is similar to each other so they seem to be closely related. + + +The morphology of the growth lines in the new specimens permits to reconstruct elements of the outer lip that has not yet been found in preserved form. It is just very feebly prosocline, almost orthocline as a whole and composed of prosocyrt parts at both sides of the selenizone, respectively, and feebly opisthocyrt on the base. The growth lines meet the selenizone in 50–60° angles at its both sides. It probably means that the rim of the outer lip is angular at both sides of a peristomal fissure, like in +Scissurellidae +. This morphology is different in Pleurotomarioidea where a wide, strongly prosocline-prosocyrt growth line belt is characteristic adapically from the selenizone, prosocyrt and narrow belt between the base and the selenizone, and markedly parasigmoidal on the base. Furthermore, these growth lines asymptotically approach the selenizone, i.e. the rim of the peristome is widely arched at both sides of the slit. These differences support the non-pleurotomarioidean systematic position for + +Wortheniopsis +. + +The sinus-bearing counterpart (“ + +Turbo +” +quirinii +Stoppani + +) in the Middle Triassic seems to represent an earlier evolutionary stage, and suggests belonging to one of the archaic higher taxa.

Selenizone bearing lunulae on earlier whorls, gradually vanishing on last whorl. + + +Description +– A gradate, medium high shell is available; its reconstructed height is about +20 mm +. The whorls have rather steep ramp that is slightly convex on the earlier whorls but flat on the last whorl. At its abapical edge, the spiral angulation is marked, sharp keel-like on the last whorl but less prominent, slightly rounded on the earlier shell parts. A strong spiral thread gives the adapical boundary for the selenizone that is concave. The outer face is markedly concave with an abapical edge that is also sharply angular. This ridge corresponds to the periphery. The base is low, subglobose as a whole and has moderately convex wall; it is rather broadly phaneromphalous and has a rounded angular umbilical rim. Near the peripheral angulation, a weaker keel also develops on the base; the suture is seamed about halfway between these two keels, so the suture is rather deeply impressed. + + +Regularly repeating collabral riblets ornament the ramp, they start at the adapical suture, and with gradual weakening, terminate at the rim of the selenizone. On the ramp, no spiral ornament is observable on the preserved shell fragment. The outer face bears a single thin thread above the midline and some obscure striae are also visible above it. Between the weak keel of the base at the peripheral belt and the umbilicus, quirinii +type +spiral ridges represent the ornament. They are denser in the abaxial half than in the remaining part of the base. The selenizone bears lunulae on the earlier whorls that gradually vanish on the last whorl.

Base convex, narrowly phaneromphalous, some possibly anomphalous. Slit rather long, selenizone concave or flat between two threads at or below midwhorl as abapical belt of ramp or blunting angulation of whorl surface. Outer whorl face more or less concave. Abaxial rim of base angular, reinforced by cord or swollen belt, providing periphery. Apex blunt, protoconch low with evenly convex whorls. Ornament consisting of collabral riblets and spiral threads in high variability of patterns; granules frequently occurring at crossing points. Lunulae mostly on early selenizone. Growth lines delicate, more prosocline and prosocyrt adapically from selenizone, feebly prosocline to opisthocline abapically; prosocline and slightly opisthocyrt on base. + + + + +Description +– Shells of + +Foveolaria + +approach turbiniform to conoidal shape with more or less gradate outline and variable spire height. They are very thin-walled, the early teleoconch whorls are simply convex but the latest whorls become obscurely to markedly angular at or below the midwhorl. The protoconch is poorly known; it has depressed turbiniform shape in the +type +species with evenly convex whorls and rather deeply impressed suture. The suture remains more or less impressed also along the subsequent whorls. The last whorl meets the base in a more or less rounded angulation that is reinforced by a swollen spiral belt or cord. The base as a whole has subconoidal to subglobular shape with feebly to strongly convex wall. In most species, a narrow phaneromphalus is observed; in some cases absence of the umbilicus seems probable. The slit is rather long as it is demonstrated by the only photo available ( +FISCHER & WEBER 1997 +, Pl. 25, +Fig. 12 +), it extends about 60° abaperturally. The selenizone is mostly concave or rarely flat between two threads at or, more commonly, somewhat below the midwhorl. Usually, it lies as abapical belt within the plane of the ramp and its abapical thread coincides with the ridge of angulation of the whorls but less frequently, it forms a third surface of the whorls, which blunts the angulation between the ramp and the outer face. Width of the selenizone is around 15% of the distance between two neighbouring sutures. In some species, the limiting threads are lacking or substituted by shallow striae on the last whorl. Outer face of the whorls is flat to concave and nearly parallel to the coiling axis; usually, its abapical rim corresponds to the periphery. + + +The ornament is composed of collabral riblets and spiral threads in high variability of patterns, frequently combined with granules and/or short riblets between pairs of spiral ridges at the crossing points. The short riblets are usually aligned collabrally forming false threads. Quirinii +type +ridges are also developed usually only on the base and mainly in the stratigraphically older (Sinemurian) species; rarely they occur also on the abapical part of the outer face. Lunulae occur mostly on the early selenizone parts, rarely present also on latest whorls. The growth lines are delicate, clearly prosocline and prosocyrt adapically from the selenizone but slightly prosocline to opisthocline and prosocyrt between the selenizone and the periphery, slightly prosocline and feebly opisthocyrt on the base. + + + + +Remarks +– The shell form and many details are similar in + +Wortheniopsis + +and + +Foveolaria + +. Most reliable distinctive characters are the position of the selenizone, the orientation and shape of the growth lines (outer lip), the width of the outer face and the distribution of the quirinii +type +ridges on the shells. The selenizone is above the midwhorl in + +Wortheniopsis + +but at/or below the midwhorl in + +Foveolaria +. + +Consequently, the width of the outer face is significantly narrower in + +Foveolaria + +than in + +Wortheniopsis +. + +The growth lines (outer lip) are almost orthocline, just feebly prosocline in + +Wortheniopsis + +but clearly prosocline in + +Foveolaria + +in the belt adapically from the selenizone. The quirinii +type +ridges appear between the abapical edge of the selenizone and the axial region of the base in + +Wortheniopsis + +, however, they are present mostly on the base or, mainly in stratigraphically younger species, substituted by simple spiral threads in + +Foveolaria + +. In few cases, they are recognisable also on the outer face in strongly modified form, e.g. in + +F. hierlatzensis +( +Szabó, 2009 +) + +or in + +F. kocsisi + +n. sp. +, with short riblet-like granules, rapidly diminishing abapically before reaching the next spiral ridge. + + +In common cases, the selenizone is the abapical belt of the ramp in + +Foveolaria + +, however, in some species, the selenizone does not lie in the plane of the ramp but blunts the angulation of the whorl surface like e.g. in + +Foveolaria conoidea + +n. sp. +or + +Foveolaria globosa + +n. sp. +(see below). If the selenizone is not clearly concave, like in + +Foveolaria hierlatzensis +( +Szabó, 2009 +) + +, these forms may recall the shape of + +Bathrotomaria +Cox, 1956 + +. However, in the latter genus, the selenizone is clearly convex, its adapical belt is part of the ramp and the abapical part belongs to the outer face, i.e. the selenizone itself is also mostly angular. + + +Species +– With the name + +Pleurotomaria foveolata +, J. A. +EUDES-DESLONGCHAMPS (1849) + +covered six different but doubtlessly related shell forms that he regarded as varieties ( + +trochoidea + +, + +subturrita + +, + +turrita + +, + +procera + +, + +pinguis + +and + +ellipsoidea + +).

Concave selenizone between two sharp ridges, abapical one just overlapping angulation of whorl surface. Base subconoidal as a whole with slightly convex wall; moderately broad umbilicus with rounded-angular rim. Umbilical lip seeming subvertical. Spiral ornament on full shell surface, excepting selenizone, threads on ramp, quirinii +type +ridges on outer face and base, all finely granulated even within umbilicus. Collabral threads observable on ramp. + + +Description +– The shell is high turbiniform, extremely thin walled with slightly convex whorls that have an angulation above the midwhorl. The ramp is feebly concave on the earlier whorls but flat on the last whorl. The selenizone is slightly protruding from its environs and it is fairly concave on all whorls; its position is on the ramp just along the angulation. Abapically, a concave outer whorl face limits the selenizone, which is wider than the ramp and rounded-angular above the suture; this angulation is more marked on the earlier whorls and widely rounded, practically absent on the last whorl. The suture appears deeply impressed since it is built somewhat adaxially from the periphery of the whorls. The base is subconoidal with slightly convex wall and a moderately wide umbilicus, having a rounded-angular rim. Remnants suggest subaxial orientation of the umbilical lip and no trace of the parietal lip has been found; no more information, concerning the peristome is preserved. + + +All whorls are covered by spiral ornament, except the selenizone. It consists of spiral threads on the ramp and quirinii +type +ridges on the outer face and the base. Weak collabral threads are observable on the ramp and the outer face of the earliest whorl with granules at the crossings with the spiral threads. The collabral threads of the ramp are vanishing only on the last whorl but lacking already from the outer face of the penultimate whorl. However, the granules remain present also on the spiral threads and ridges of the latest shell parts, even on the base and within the umbilicus. The growth lines and the collabral ornament are feebly prosocline and clearly prosocyrt on both sides along the selenizone. The growth lines of the base are nearly orthocline and somewhat opisthocyrt. + + +Remarks +– Granules of the spiral ridges on the base are almost fully removed by erosion, however some remnants indicate in strong magnification that they are present on all ridges. + + + +Wortheniopsis bakonyensis + +n. sp. +differs from + +W. rakusi + +n. sp. +in having the angulation of the whorl surface from a much earlier growth stage; i. e. all whorls (3) are angulated in + +W +. +bakonyensis + +but only the last one in + +W. rakusi + +. It means also that a ramp has developed only on the last whorl of + +W. rakusi + +while in + +W +. +bakonyensis + +it is present (at least) two whorls earlier. + +W +. +bakonyensis + +has feebly concave outer face on all preserved whorls but + +W. rakusi + +has flat outer face on the last whorl and feebly convex corresponding belt on the former whorls. In + +W. rakusi + +, no granulation is present neither on the outer face nor on the base. + + +Distribution +– Lower?
