DIAGNOSIS (genus): Euleptes may be distinguished from all other gekkonids by the following combination of characteristics: digits bearing a single pair of enlarged ("leaf-toed"') terminal scansors; dorsal scalation atuberculate; granules on snout not larger than those on dorsum of body; no rostral crease or division; first supralabial enters nostril; no enlarged chinshields; a single large cloacal spur on each side of vent, especially well-developed in males; preanal pores absent; subcaudal scales not transversely enlarged, tail prehensile, but without well-developed terminal scansorial pad; margins of pupils crennelate in preserved specimens; no sexual dichromatism; nasal bones paired; parietals paired; premaxilla with relatively short, triangular nasal projection; frontal moderately broad, strongly constricted over orbits, without maxillary contact; approximately 25 maxillary tooth positions (unilateral) in adults; postfrontal bones with subequal anterior and posterior projections, or with thicker anterior projection, without pronounced lateral spine; stapes perforate; coronoid bone weakly developed, barely raised above the level of dentary tooth row; second ceratobranchial arch of hyoid present, inner proximal ceratohyal process lacking, medial projection of hyoid cornu much reduced; neural arches of atlas fused, at least in adults; 26 presacral vertebrae, 2 lumbar vertebrae; 3 cervical ribs, 2 sternal ribs, 2 mesosternal ribs; 0-1 pair of clavicular fenestrae, clavicles not strongly dilated; interclavicle dagger-shaped, with small transverse processes; union of scapula and precoracoid ray of epicoracoid cartilaginous; phalangeal formulae unreduced (2-3-4-5-3 manus, 2-3-4-5-4 pes); cloacal sacs and bones present, a second, irregular (second) set of cloacal bones is associated with the cloacal spur in males; clutch size two (Fretey 1975; Rieppel and Schneider 1981), or less frequently one (Wiedersheim 1876; Klingelhöffer 1957). Euleptes may be distinguished from all other leaf-toed geckos except Asaccus and New World and southeast Asian Phyllodactylus by its perforate stapes. It may be differentiated from all of these by the absence of tubercular scales and the fusion of the atlantal arches. The presence of a second pair of cloacal ossifications, first noted by Wiedersheim (1876), is a derived condition apparing elsewhere among leaf-toed geckos only in P. peringueyi (Branch and Bauer 1994), in which it is variable, and in some Paroedura (contra Nussbaum and Raxworthy 1994). The prehensile tail of Euleptes has long been recognized (Fitzinger 1843; Wiedersheim 1876) and its superficial morphology has been investigated in some detail (van Eijsden 1983). Urocotvledon also has a prehensile tail, but Kluge (1983) considered the presence of a well-demarcated scan~ sorial pad as synapomorphic for that genus only,
|Comment||Synonymy: fide Wermuth 1965 and Rösler et al. 2018.|
Distribution: Extinct from Galitone and Cani islets (Tunisia) [M. Delaugerre, pers. comm., 6 Aug 2013].
Type species: Phyllodactylus (Euleptes) wagleri FITZINGER 1843 is the type species of the genus Euleptes FITZINGER 1843: 9. The genus Euleptes has been resurrected by Bauer et al. 1997.
|Etymology||Named after the type locality.|
The genus was named after the Greek eu- (true or very) and leptos (small, thin, or delicate), apparently in reference to the overall shape and size of the type species, although this was not made explicit by Fitzinger (1843). The generic name is feminine.
