SynonymMarmorosphax boulinda SADLIER, SMITH, BAUER & WHITAKER 2009 
DistributionNew Caledonia

Type locality: Massif du Boulinda, 2 km southwest Mt. Boulinda at headwaters of Oua Népoua, 21°16’34”S, 165°08’09”E.  
Reproductionviviparous (phylogenetic imputation, fide Zimin et al. 2022) 
TypesHolotype: MNHN-RA 2005.0319 (formerly AMS R163197) 
DiagnosisDiagnosis: Marmorosphax boulinda n. sp. can be distinguished from other members of the genus by the following combination of characters: dorsal scale rows 75-76; fourth toe lamellae 36-40; dorsal surface with a pattern of alternating brown and white transverse rows (each one scale width); lateral surface lacking obvious pale markings (males) or with scattered pale blotches; underside of head with obscure grey blotches on the throat. Marmorosphax boulinda n. sp. is most similar in colouration and scalation to M. montana. The presence of narrow alternating brown and white transverse rows on the dorsal surface will distinguish Marmorosphax boulinda n. sp. from Marmorosphax montana which has a pattern of roughly alternating broad brown (2-3 scales wide) and black (one scale wide) transverse rows on the dorsal surface. Scalation characters will readily distinguish Marmorosphax boulinda n. sp. from Marmorosphax kaala n. sp., Marmorosphax taom n. sp. and Marmorosphax tricolor, all of which have fewer scales under the toes (see Table 1). 
CommentAbundance: only known from its original description (Meiri et al. 2017). This is one of the species called 'lost' and 'rediscovered' by Lindken et al. 2024. 
EtymologyThe epithet is a noun in apposition in reference to the type locality, the Boulinda Massif.
