Abstract
Glyphoglossus volzi (van Kampen, 1905; Sumatra) and G. minutus (Das, Yaakob & Lim, 2004; Peninsular Malaysia) have been treated as distinct species based largely on morphological characters. We examined a preserved male of Glyphoglossus from Jambi (central Sumatra), compared it to the lectotype of G. volzi and topotypic G. minutus, and reconstructed relationships using a 448 bp fragment of mitochondrial 16S rRNA. Phylogenetic analyses (BI, ML) place the Jambi specimen with topotypic G. minutus with shallow divergence (p-distance 1.86%), and morphological comparisons show concordant diagnostic traits and overlapping mensural data. Given the congruence of evidence and the historical taxonomic context, we regard G. minutus as conspecific with G. volzi and formally place G. minutus in synonymy under G. volzi. We clarify generic and species-level nomenclature, correct several literature and distributional statements, and highlight the limits of short mtDNA fragments for delimitation in Microhylidae. Our results underscore the value of targeted sampling of elusive, fossorial taxa in biogeographically connected regions. On the basis of concordant morphological evidence and 16S data, we treat Calluella minuta as conspecific with Glyphoglossus volzi and place it in synonymy.
