The wings and wing-microsculpturing, hitherto either unknown or poorly known, in the small, rare family Indotermitidae, is described here in imagoes ofIndotermes rongrensis. Wings are transparent, colourless and weakly hairy; wing venation is described. Microsculpturing on wings consists of a row of small, pointed papillae at the anterior margin and a dense carpet (3100–3800/mm2) of minute (1–6 μm) simple, nonasteroid micrasters on both the membranes. The phylogeny of the Indotermitidae is discussed. It arose as a lone branch (with 3-segmented tarsi) from the initially 4-segmented ancient Termitidae stock.
