(Figs 15, 45–48)

Heliothripoides Okajima, 1987c: 294 . Type species: Heliothripoides reticulatus Okajima, by monotypy.

This genus is presumably a member of the Phlaeothrips -lineage of fungus-feeding species. The type species was described from Borneo, but a second species of the genus from that island is described below.
