A time‐calibrated phylogenetic tree indicates that the evolution of sympatric, montane, endemic species from closely related, co‐distributed lineages of the H emiphyllodactylus harterti group were not the result of rapid, forest‐driven, climatic oscillations of the L ast G lacial M aximum, but rather the result of infrequent episodes of environmental fluctuation during the L ate M iocene. This hypothesis is supported by genetic divergences (based on the mitochondrial gene ND2 ) between the three major lineages of the H . harterti group (17.5–25.1%), their constituent species (9.4–14.3%), and the evolution of discrete, diagnostic, morphological, and colour pattern characteristics between each species. Sister species pairs from two of the three lineages occur in sympatry on mountain tops from opposite sides of the T hai– M alay P eninsula, but the lineages to which each pair belongs are not sister lineages. A newly discovered species from G unung T ebu, Terengganu State, Hemiphyllodactylus bintik sp. nov. , is described. © 2015 The Linnean Society of London
