Dierogekko validiclavis — BAUER et al. 2006
Dierogekko validiclavis — BAUER et al. 2012
|Distribution||New Caledonia (regions of Mt. Panié and Mt. Mandjélia)|
Type locality: Mt. Panié (500–600 m elevation), Province Nord, New Caledonia, 20°33′S, 164°45′E [published coordinates], 20°33′43′′S, 164°46′50′′E [corrected coordinates].
|Types||Holotype: AMS R77855, collected by R.A. Sadlier and P.R. Rankin, 17 December 1978.|
|Diagnosis||DIAGNOSIS (genus): Dierogekko may be distinguished from all other New Caledonian diplodactylid geckos by the following combination of character states: body size very small (< 46 mm SVL); head small; tail 92–120% of SVL; dorsal scalation granular, homogeneous; body without extensive skin webs or flaps; expanded subdigital lamellae under all toes; lamellae under penultimate phalanx of digits II–V of manus and pes paired or single; claw of digit I of manus and pes in a groove in the apical lamella between a larger medial scansor and a smaller lateral scansor; precloacal pores in one or two rows in males (10–20 pores in total), not extending onto thighs; dorsal pattern of longitudinal lines or series of spots or patternless, never with transverse markings; venter usually cream to light brown, sometimes pale yellow (BAUER et al. 2012).|
Members of the genus Dierogekko superficially resemble members of the genera Bavayia and Oedodera, all of which are relatively small and predominantly brown in color. They differ from the recently described Oedodera(Bauer et al. 2006) in possessing divided distal subdigital lamellae (except D. poumensis) and in lacking a swollen neck and medial apical scansors on digit II of the pes. Dierogekkospp. may be distinguished from Bavayia sauvagii, B. ornata, and B. madjoby the position of the claw of digit I of manus and pes (in a groove between medial and lateral portions of a cleft apical scansor vs. lateral to a single medial apical scansor), from B. cyclura, B. montana, B. crassicollis, B. robusta, B. geitaina, andB. exsuccidaby the absence of transverse dorsal markings and by much smaller body size (< 50 mm vs. > 72 mm max. SVL) in all but the last of these species, and from B. pulchellaand B. septuiclavisin having the entire dorsal surface lighter than the flanks and demarcated by a series of narrow, continuous or broken stripes (vs. a narrow pale vertebral stripe and/or no white border stripe) (BAUER et al. 2006).
Diagnosis (genus): Digits with paired terminal scansors that lack lamellae, reduction of phalangeal formula of manus to 184.108.40.206.3, no transverse processes on autotomic caudal vertebrae except sometimes the first (ARNOLD 1977), no femoral pores, cloacal sacs or bones, only one egg laid at a time and left oviduct absent. The left oviduct is present in Phyllodactylus and in the apparently related Paroedura [ARNOLD & GARDNER 1994].
Type species: Bavayia validiclavis SADLIER 1988 is the type species of the genus Dierogekko BAUER et al. 2006.
