SynonymDierogekko poumensis BAUER, JACKMAN, SADLIER & WHITAKER 2006
Dierogekko poumensis — SKIPWITH et al. 2016 
DistributionNew Caledonia (Province Nord, Sommet Poum)

Type locality: New Caledonia, Province Nord, Sommet Poum, vicinity telecommunications tower, Poum, 20°14′19′′S, 164°01′56′′E (elevation 200 m).  
TypesHolotype: MNHN-RA 2004.0021: Adult male; collected by A.M. Bauer, R.A. Sadlier, T. Jackman, S.A. Smith and G. Watkins-Colwell, 25 January 2003. 
DiagnosisDIAGNOSIS. Dierogekko poumensis can be distinguished from all congeners on the basis of the following combination of characters: size small (to 38.3 mm SVL), 1 internasal scale; distal subdigital scansors typically undivided or incompletely divided; male preanal pores in a single row of 8–11. Crown of head mottled with beige spots, middorsal pale area bisected by irregular pale to mid-brown streak; cream and dark brown borders of dorsal pale region well demarcated; cream lines become bright white on sacrum or pygal portion of tail; original and regenerated tails typically with irregular yellowish to rusty orange background wash.
CommentCONSERVATION STATUS. Dierogekko poumensis is extremely common at its type locality and occurs in lesser abundance at other sites on the massif. However, the total area of Sommet Poum is small and populations of D. poumensisare patchy. Given the highly restricted known range of this species and serious threats to its habitat, BAUER et al. (2006) regard it as Critically Endangered.

Abundance: only known from the type locality (Meiri et al. 2017). 
EtymologyThe specific epithet poumensis refers to the occurrence of this species on Sommet Poum, the northernmost of the northwest ultramafic peaks of the Grande Terre. It is roughly sympatric with D. inexpectatus.
