A new species of scarab beetle, Termitotrox icarus sp. nov., is described from central Myanmar, being the third representative of the genus Termitotrox Reichensperger, 1915 from the Indo-Chinese Subregion of the Oriental Region. The majority of the type series was collected from the walls of fungus garden chambers built in the nests of the termite Odontotermes proformosanus Ahmad, 1965. Termitotrox icarus sp. nov. can be easily distinguished from the known Termitotrox as it possesses wing-shaped trichomes on the elytra, the more elongate habitus shape in dorsal view, the basomedian section of pronotum not protruding backwards, a pair of distinct costae on the pronotal basomedian section strongly developed, a median costa on anterior pronotal margin strongly developed, the elytral striae narrower than interstriae, the lack of trichomes at the base of elytral sutural stria, and a mid-range body length of 1.5–1.9 mm. The ‘carrying behavior’ by the host termites is reported for the first time for Termitotrox and a strategy for the dispersal of flightless termitophilous scarabs is hypothesized.
