Trichopterygini

This tribe includes the Lobophorini (See Larentiinae) and can be clearly defined on several morphological characters. It occurs worldwide and contributes a major proportion of the larentiine fauna of the Indo-Australian tropics. Species are found from the lowlands to 4000m, with the greatest diversity being encountered in montane forests (Holloway, 1986b). It has been reviewed from an Australian perspective by Dugdale (1980) and for China by Xue (1992).

All genera have the anal area of the male hindwing reduced, often modified into a lobe or lappet that sometimes bears what appears to be a row of carinae. The male second abdominal sternite is usually modified, with a central sac or a pair of sacs supported from a pair of triangular structures (Figs 287, 313). In the male genitalia the valve often has both costal and saccular ornamentation. In the female, the bursa is usually generally scobinate.

The larvae and pupae of species in several of the temperate genera are described by Hashimoto (1982, 1985) but no clear tribal characteristics are indicated. Patocka (1981) noted several pupal characteristics consistent within the European members of the tribe.

The Bornean fauna consists of just over forty species distributed amongst ten genera.
