Drusilla khamhengi PACE, 1986

Material examined: Thailand: 10 exs., Tak province, Umphang district, Song Bae Stream, Thung Yai Wildlife Sanctuary, 15°28'N, 98°48'E, 300 m, evergreen rain forest, 18–27.IV.1988, leg. Brendell (BMNH, cAss) . Laos: 1 ♀, Vientiane Prov., 7.5 km N Houay Ileuth, near Nam Lik river, 18°37'N, 102°25'E, 23.–24.II.2014, leg. Cibulskis (cAss) .

Comment: This species had been recorded only from Thailand (ASSING 2016b). The above female from Laos is distinguished from previously examined material from Thailand by a spermatheca of slightly different shape and a posteriorly somewhat more produced tergite VIII, but otherwise no differences were found suggesting that the specimen should represent a distinct species.
