Trichastoma rostratum is known from the Sundaic lowlands, in south Tenasserim, Myanmar; peninsular Thailand; Singapore (rare); Sabah, Sarawak and peninsular Malaysia; Kalimantan (including northern islands) and Sumatra (including offshore islands), Indonesia, and Brunei. It is fairly common, though localised, throughout this range.
