Genus Malaisinia Hering

Malaisinia Hering, 1938: 54 . Type species M. pulcherrima Hering, 1938 .

This genus is characterized by having 3–4 pairs of frontal, 2 pairs of orbital and 1 pair of scutellar setae [apicals absent], scutum covered with short, yellowish, scale-like setulae, wing apex dark with at most a very small hyaline subapical spot and an unusually angled basal hyaline indentation in cell m. Hancock (2001) included three species: pulcherrima Hering from Myanmar and W China, variegata (Radhakrishnan) from NE India and biseta (Wang) from SW China. A fourth species is added here from northern India. Only the host plant of M. variegata is known; it forms stem galls on Inula cappa ( Asteraceae: Radhakrishnan, 1984).

Key to known species of Malaisinia Hering
