Hastula hungarica Csepreghy-Meznerics, 1954 — Pálfy et al. 2008: 106 . Type material. Holotype M.622971 , Hungarian Natural History Museum, Budapest, SL: 10.0 mm, MD: 2.9 mm , Mátraverebély ( Hungary ), illustrated in Csepreghy-Meznerics (1954 : pl. 8, fig. 4). The specimen is glued on a card. No additional material is available. FIGURE 6. Hastula hungarica Csepreghy-Meznerics, 1954 . A 1 –A 2 . Holotype M.622971, Mátraverebély (Hungary). Revised description. Small, obese shell of up to eight teleoconch whorls; apical angle 34°. Protoconch and early teleoconch whorls strongly abraded. Sculpture on spire whorls of narrow, opisthocline axial ribs, separated by wider interspaces. No spiral sculpture. Suture narrowly incised. Whorl profile weakly convex. Axial sculpture weakening slightly on last two whorls. Last whorl high, weakly convex, 47% of total height. Base slowly contracting. Fasciole low, broad. Aperture moderately wide. Columella weakly twisted, weakly excavated in adapical half. Anal canal indistinct. Outer lip thin. Basal lip convex, wide. Siphonal canal very short, wide, deeply notched, slightly deflected to the left. Synonyms. Strausz (1959) introduced Terebra ( Hastula ) striata cserhatensis as new name for Hastula hungarica Csepreghy-Meznerics, 1954 because he considered it a homonym of Terebra ( Acus ) hungarica Halaváts, 1884 . However, the two taxa were established in different genera. Secondary homonymy did indeed occur when Csepreghy-Meznerics (1972) placed Halaváts’ species in Hastula . This placement was incorrect because Terebra ( Acus ) hungarica Halaváts, 1884 is not a Terebridae but is placed herein in Batillariidae (see below). Paleoenvironment. Inner neritic, coastal marine (own data, M .H.). Discussion. This species is known only from a few specimens. These specimens all represent a small obese species with some variability in axial sculpture including nearly smooth specimens. Hastula hungarica might belong to a group of species comprising the living West African Hastula knockeri ( Smith, 1872 ) , H. lepida ( Hinds, 1844 ) and H. leloeuffi Bouchet, 1983 and the Mediterranean Late Miocene to Pliocene Hastula costulata ( Borson, 1820 ) , which differ in being larger and slenderer but develop a comparable sculpture. Among the extant Indo-West Pacific Terebridae , Hastula solida ( Deshayes, 1857 ) represents a similar morphology but is much larger and has more prominent and close set axial ribs. Distribution in Central Paratethys. Badenian (Middle Miocene): Cserhát Mountains : Mátraverebély ( Hungary ) ( Csepreghy-Meznerics 1954 ; Strausz 1959 ); Pannonian Basin : Várpalota ( Hungary ) ( Strausz 1966 ).
