A Median joining networks of Dravidoseps gen. nov. for three nuclear markers, nodes scaled by haplotype frequency, hatch marks on connecting lines indicate mutations and black circles indicate unsampled intermediate haplotype states. B Maximum likelihood ND2 phylogeny of Dravidoseps gen. nov. with posterior probability/ bootstrap support shown at nodes (outgroups not shown) and species delimitation results shown by alternating black and grey bars with total putative species below (BC, barcoding gap; PT, PTP; MP, mPTP; PR, PRLR; RAG, RAG-1), (square bracket indicates the two separated black squares are a single species). C Histogram of uncorrected pairwise ND2 sequence divergence within Dravidoseps gen. nov. with the barcoding gap marked by an arrow. Putative species are coloured as in Figure 1 on the networks and with transparent boxes on the mtDNA tree.
