Type material.

Lectotype (NHMW).

Diagnosis.

1.8 mm long (n = 1); 2.57 × as long as wide. This species is distinguished by its minute size; eyes that are nearly as large as the head and very weakly emarginated; and declivity bearing scale-like setae.

Similar species.

None.

Distribution.

Vietnam.

Host plants.

Unknown.

Remarks.

This tiny species is only known from the lectotype specimen which is point mounted with an excessive amount of glue. This mounting prevented the examination of most antennal and ventral characters, including the legs. It is likely that this species belongs in a different genus, potentially Tricosa , but these characters will need to be examined before the species can be transferred.
