Generic abbreviation: Km.

Type species: Topomyia decorabilis Leicester

Etymology: Tran Thi Bach Kim (wife of Vu Duc Huong)

The genus Kimia comprises five speciesKm. decorabilis (Leicester), Km. imitata (Baisas, 1946), Km. miyagii (Toma & Mogi, 2003), Km. nemorosa (Gong) and Km. suchariti (Miyagi & Toma). Kimia species have distinctive broad silver scale patches on the antepronotum, pleuron and sternum. Like Malaya and Topomyia species, Kimia have a distinctive median stripe of silvery white scales down the center of the scutum.

 

DIAGNOSTIC CHARACTERS  (Click photo to zoom in.)

ADULT (illustrated): Head: Vertex with silvery scales. Thorax: Silvery scales on posterior antepronotum, pleuron, C-IIII and abdominal sternum; silvery, flat, broad scales in two rows along midline of scutum; scutellar lobes with broad, dark scales. Wing: Upper calypter lacking setae. Abdomen: Terga dark-scaled; sterna with silvery scales, IX-S without setae and scales

LARVA (not illustrated): Head: Maxillary brush modified into an articulated rigid bundle; maxillary apical tooth stout. Terminal segments: Comb without comb plate; comb scales in a single irregular row; siphon without pecten, with dorsal and ventral double rows of setae along entire length; seta 4-X multi-branched, single.

BIONOMICS

Immatures

Kimia larvae are bamboo-associated, found in insect bore holes in standing bamboo internodes, and rainwater collections in bamboo stumps. The maxillae of Kimia larvae are modified for grasping, suggesting predacious feeding behaviors. During the link-rearing of the holotype of Km. suchariti, the larva reportedly captured and ate several Armigeres and Tripteroides larvae.

Adults

Very little is known on the adult biology of Kimia species. Adults have never been captured in the wild, and are known only from larval rearings. That they are not attracted to human bait or light traps suggests (like the closely related Malaya and Topomyia), Kimia most probably do not blood feed. Given the predacious nature of the larvae, it is likely that adults are autogenous.
