Integrative taxonomy delimits and diagnoses cryptic arboreal species of the Cyrtodactylusbrevipalmatus group (Squamata, Gekkonidae) with descriptions of four new species from Thailand.

ABSTRACT: Species delimitation and species diagnosis must remain separate operations to avoid constructing taxonomies comprised of non-monophyletic species based on morphological similarity as opposed to phylogenetic propinquity. This is particularly true for highly specialized species such as the range-restricted upland taxa in the Cyrtodactylusbrevipalmatus group of Indochina where strong selection pressure for an arboreal lifestyle has contributed to morphologically similar but distantly related species. This in turn, has resulted in a history of erroneous taxonomies that have actually obscured rather than revealed the diversity within this group. A Bayesian phylogeny of the C.brevipalmatus group recovered at least 15 putative species-level lineages, at least seven of which are unde
