A phylogenetic analysis based on the mitochondrial DNA fragments 16S and COI and the nuclear marker wingless, and a phylogeographic analysis using a COI fragment were carried out on two subspecies of Cosmodela aurulenta (C. a. juxtata and C. a. aurulenta). The results support the hypothesis that these two subspecies are significantly different to be considered as separate species that diverged around 1.5 MYBP. TAXONDNA analysis was used to investigate the capability of the COI region as a marker for discriminating both entities and to quantify intra and inter-taxa genetic variation. The minimum distance between C. aurulenta and C. juxtata was 2.7837%, and no overlap of intra and inter-taxa genetic divergence was observed. Both taxa, here considered as valid species, occur in sympatry in the Malay Peninsula, with C. aurulenta most probably originating from the area and C. juxtata a secondary colonizer that expanded southwards from the Asian mainland. Our data infer a continental origin of the Indonesian samples of C. aurulenta, and they most likely dispersed across the land bridges that emerged during glacial maxima to form Sundaland.} }
