Hypersypnoides Berio

Type species: congoensis Berio, Africa.

Synonym: Othresypna Berio (type species: subolivacea Walker, Borneo).

This genus consists of one African species that typifies it, and a large number of mostly Oriental ones that Berio & Fletcher (1958) placed in subgenus
Othresypna Berio. The former has spined tibiae, the latter have not. All species have a spine extending the apex of the fore-tibia. The forewing facies of the Indo-Australian species is often rather uniform and highlighted by a paler reniform that may be surrounded by smaller satellite spots and two irregular rows of pale marks between it and the costal margin. The male antennae are fasciculate.

In the male abdomen, the eighth segment is reduced to a narrow ring of sclerotisation. The genitalia frequently have a dorsal process to the uncus, which is short, at the end of a long extension from the strongly angled tegumen; lateral mounting with removal of the right valve can display this effectively, though this will render comparison difficult with the drawings of the dorsal aspect of the uncus in Berio & Fletcher (1958). The valves are relatively deep, the flange central and oblique. The ductus ejaculatorius inserts only just subbasally in the aedeagus in some species.

The female
fenella Swinhoe, submarginata Walker) have the ostium wide, just posterior to the ventral interruption of the eighth segment. The ostium forms the mouth of a sclerotised, goblet-like ductus. The bursa is pyriform, without any significant ornamentation. The seventh sternite is only slightly reduced. The genus is most diverse in the Himalayan region and western China, but has five species in Borneo (four montane). The most easterly species is in the S. Moluccas.

The larva (see below) resembles those of the previous genus. The host plants noted by Miyata (1983) are also similar: Quercus (Fagaceae) and Rubus (Rosaceae).
