Craspedoniini Bradley & Galil, 1977 : 187. [Unnecessary replacement name] Phibalosomini (Sectio V: Phibalosomata) Redtenbacher, 1908 : 399 (in part). Description: ♀♀/♂♂ ( Figs. 9–10 ). Medium-sized to large (body lengths: ♀♀ incl. subgenital plate 107.0–161.0 mm; ♂♂ 78.0–115.0 mm), Cladomorphinae with remarkable sexual dimorphism. Body surface shiny, ♀♀ plain bright green. ♂♂ with short tegmina and well developed alae ( 48.2–53.2 mm ), ♀♀ apterous. ♂♂ elongate and moderately slender with body cylindrical. ♀♀ considerably larger and much broader than ♂♂, body strongly dorsoventrally flattened with meso-, metathorax and abdomen strongly laterally dilated (maximum body width 28.0–34.0 mm); body rhombic in cross-section. Head longer than wide, strongly globose and convex; vertex smooth. No ocelli. A gula is present. Antennae very long, slender and filiform, longer than head, thorax and median segment combined and consisting of>80 antennomeres. Pronotum distinctly narrower than head and mesonotum. Mesothorax of ♂♂ elongate and slender, 2.5x longer than head and pronotum combined, minutely granulose; mesosternum with a fine longitudinal median carina. Mesothorax of ♀♀ broadly and semi-circularly expanded, 1.5x longer than wide. Mesonotum strongly convex dorsally and armed with a cluster of blunt tubercles in the raised anterior portion; lateral margins expanded, lamellate and bluntly dentate. Mesopleurae strongly dilated, forming a longitudinal lamella with the outer margin dentate. Mesosternum strongly tectiform and with a prominent and broad, tuberculose longitudinal median keel; lateral margins slightly expanded and with a longitudinal row of tubercles ( Fig. 15 ). Median segment distinctly longer (♂♂) or roughly equal in length to metanotum (♀♀). Abdominal segments II–VI of ♂♂ parallel-sided and distinctly longer than wide. In ♀♀ tergites and sternites II–VI with lateral margins strongly expanded and lamellate; all transverse. Praeopercular organ of ♀♀ represented by a small spiniform projection on sternum VII ( Fig. 16 ). Epiproct and cerci of both sexes very small and considerably shorter than anal segment. Gonapophyses VIII of ♀♀ elongated, up-curving and projecting well beyond posterior margin of anal segment ( Fig. 16 ). Gonoplacs developed ( Fig. 16 ). Vomer of ♂♂ produced, well sclerotized and elongate-triangular. Phallus totally covered with minute black denticles. Poculum very bulgy, strongly convex and extending ventrally by more than 2x the body width ( Fig. 17 ). Subgenital plate of ♀♀ distinctly keeled longitudinally, boat-shaped, tapered towards a narrow ± acute apex and projecting considerably over anal segment ( Fig. 16 ). All legs elongate and slender (♂♂) to moderately robust (♀♀), all distinctly carinate but entirely unarmed. Femora trapezoidal, tibiae almost triangular in cross-section with dorsal carinae strongly approaching each other. Profemora compressed and curved basally with posterodorsal carina reduced and considerably lower than anterior carina; medioventral carina distinct and roughly midways on ventral surface of femur. Medioventral carina of meso- and metafemora very faint. Tarsi simple. Basitarsi at least as long as following three tarsomeres combined and carinate dorsally with the two dorsal carinae melted with another. Eggs ( Figs. 18–19 , 49 ): Medium-sized, strongly globose and almost spherical in lateral aspect; slightly oval in cross-section. Polar-area with a wide depression. Operculum elliptical, flat and with a convex, net-like hollow expansion which covers the complete disc. Micropylar plate covering about half of capsule-length, broadly ovoid with a raised outer margin and convex central region. Internal micropylar plate open and with a narrowing of the posteromedial gap before it widens into the notch. Median line indistinct, short, very well separated from the plate and distinctly displaced towards the polar-area ( Fig. 49 ). Differentiation ( Table 1 ): Several features such as the presence of a gula, filiform antennae, the elongate, filiform gonapophyses VIII and presence of gonoplacs in ♀♀, specialized poculum of ♂♂ and presence of a median line in the eggs prove close relation to the South American Cladomorphini (→ 4.2.2). Cranidiini however clearly differs from Cladomorphini by: the shiny body surface; green general colouration; entirely unarmed legs; indistinct medioventral carina of the profemora which is roughly central on the ventral surface of the profemur; roughly trapezoidal cross-section of the profemora and very faint medioventral carina of the meso- and metafemora of both sexes. Furthermore, ♀♀ readily differ by: the strongly flattened and laterally dilated, leaf-like body; convex mesonotum and strongly longitudinally tectiform mesosternum ( Fig. 15 ). Males are also well distinguished by the strongly enlarged and very bulgy poculum which ventrally extends by more than 2x the body diametre, as well as the specialized phallus which is totally covered with minute black denticles. The eggs differ from those of Cladomorphini by having the micropylar plate oval and relatively shorter (<½ of the dorsal capsule surface) and the posteromedian notch of the plate with a narrowing before it widens into the gap ( Fig. 49 ). The completely reduced leg armature and tectiform mesosternum of both sexes, the prominently dilated mesothorax and abdomen of ♀♀ as well as the prominently enlarged poculum and spinulose phallus of ♂♂ appear to be autapomorphies of Cranidiini , which suggest the tribe might be the sister-group of Cladomorphini + Cladoxerini ( Fig. 409 ) and at once distinguish it from these two tribes. The elongated gonapophyses VIII and presence of gonoplacs in ♀♀ as well as the developed gula are shared with Cladomorphini and Cladoxerini . Because of the erroneous and confusing treatment of Cranidiini by Zompro (2004: 135) a detailed comparison and differentiation of Cranidiini and Haplopodini is presented in Table 1 , which emphasizes the striking differences between these two tribes and confirms the separate status of Haplopodini as well as the monotypy of Cranidiini .

Comments: When Günther (1953: 557) established the tribe Cranidiini , Cranidium Westwood, 1843 was the only genus contained. A comprehensive treatment and re-description of the type-genus was presented by Hennemann, Conle & Delfosse (2007) . Brock (1998b) described a second Jamaican genus in the tribe, Paracranidium . This however, is here shown to be not closely related and to take on a rather isolated position within the re-established tribe Haplopodini Günther, 1953 (→ 5.6), hence is removed from Cranidiini . Another South American genus, Aplopocranidium , was added by Zompro (2004: 135) but is also not closely related to Cranidium and was transferred to Cladomorphini by Hennemann & Conle (2010: 104) who provided a comprehensive treatment of Aplopocranidium including a description of the previously unknown ♂♂. Zompro (2004: 135) removed the genera Aploploides Rehn & Hebard, 1938 , Haplopus Burmeister, 1838 and Diapherodes Gray, 1835 from Hesperophasmatini Bradley & Galil, 1977 and transferred them to Cranidiini . It is surprising that Zompro (2004: 135) argued the supposed close affinity of these three Antillean genera to Cranidiini exclusively on the fact that they have the same “smooth and shining body” and mentioned this as the only feature that in his opinion characterizes Cranidiini within Cladomorphinae . This act however is very arbitrary, since a wide range of very striking and fundamental morphological differences are present between Cranidiini and the mentioned three genera (→ Table 1 ). Nor does this “feature” hold true for all taxa that Zompro transferred to Cranidiini , e.g. ♀♀ of Haplopus -species and ♂♂ of certain Diapherodes -species have a rather dull and ± sculptured body surface. As can be seen in Table 1 Aploploides , Haplopus and Diapherodes are not at all closely related to Cranidium and here shown to form a very well separated clade, defined as the supposedly monophyletic tribe Haplopodini rev. stat. (→ 5.). Consequently, these three genera are here removed and Cranidiini is a monotypical and very well separated tribe within the subfamily Cladomorphinae . Clark-Sellick (1998: 221, fig. 32a, b) and Hennemann, Conle & Delfosse (2007 : 360) stated the egg of Cranidiini to lack a median line, although the latter authors showed there to be a median line in the illustration of the internal plate (2007: 365, fig. 12). Subsequent examination of more examples has shown a short and rather indistinct median line to be present. However, it is rather short and very well separated from the micropylar plate, being displaced towards the polar-area by more than its own length. A captive reared ♀ of C. gibbosum at hand from the first author's collection (coll. FH, No. 0470-14) represents the new length record for this species, measuring 161.0 mm including the subgenital plate. Distribution: Restricted to Northeastern South America and so far recorded from Northern Brazil , French Guiana and Suriname ( Hennemann, Conle & Delfosse, 2007 : 366). Genus included: 1. Cranidium Westwood, 1843 : 49 .
