Discussion. As noted by Lansbury (1968), E. uncata is very similar in many respects to E. mandalayensis Distant. The specimens from East Kalimantan, however, closely match Lansbury’s figures for E. uncata in regard to the shape of the metaxiphus, and the fine details of the LABP, and as such are assigned to that species for present. The specimens from Tebakang, Sarawak are also consistent with Lansbury’s figures, and closely match the coloration of other USNM specimens of E. uncata from Preanger, Java and Ft. De Kock, Sumatra, despite being slightly smaller in size. This species is now known to occur on all the Greater Sunda Islands of Java, Sumatra, and Borneo (Lansbury 1968, Zettel et al. 2012), with the current records documenting is presence in Mahakam River basin of East Kalimantan Province on the latter island.
