﻿AbstractAn integrative analysis recovered a new species of theHemiphyllodactylustypusgroup from a karst formation in Lung Cu Commune, Dong Van District, Ha Giang Province, northeastern Vietnam.Hemiphyllodactyluslungcuensissp. nov.is embedded within clade 6 of thetypusgroup, bearing an uncorrected pairwise sequence divergence of 4.6–20.2% from all other species based on a 1,038 base pair segment of the mitochondrial NADH dehydrogenase subunit 2 gene (ND2). It is diagnosable from other species in clade 6 by statistically significant mean differences in normalized morphometric, meristic, and categorical characters. A multiple factor analysis using the three aforementioned character types recovered its unique, non-overlapping placement in morphospace as statistically significantly different from that of all other species in clade 6. The description of this newHemiphyllodactylusspecies contributes to a growing body of literature underscoring the high degree of herpetological diversity and endemism in karst landscapes in Vietnam as well as in the genusHemiphyllodactylus.
