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 fi rst time for Termitotrox and a strategy for the dispersal of fl ightless termitophilous scarabs is hypothesized.

Termitotrox cupido sp. n. is described from Cambodia and represents the first discovery of Termitotrox Reichensperger, 1915 from the Indo-Chinese subregion of the Oriental region. The type series was collected from fungus garden cells of Hypotermes makhamensis Ahmad, 1965 (Isoptera, Termitidae, Macrotermitinae). Hypotermes Holmgren, 1917 was previously an unknown host of Termitotrox species. The new species is readily distinguished from all known congeners by having wing-shaped trichomes on the elytra and is most probably the world's smallest scarab, at 1.2 mm in length.

Termitotroxvenus sp. n. is described from Cambodia and represents the second discovery of Termitotrox Reichensperger, 1915 from the Indo-Chinese subregion of the Indomalayan region. Most of the type series was collected from refuse dumps in fungus garden cells of Macrotermescf.gilvus (Hagen, 1858). Macrotermes Holmgren, 1910 was previously an unknown host of Termitotrox species. The new species is easily distinguished from all known congeners by having wing-shaped trichomes on the elytra and the larger body size, at 2.5 mm in length. We also describe the mouthparts to complement the description of the genus Termitotrox.
