Diagnosis

Zambion kasparyani can be distinguished from all other Zambion spp. by combination of both of the following characters: 1) absence of a ventral transverse carina on the propodeum extending from the metasomal foramen to the pleural carina (Fig. 48) (contrast with condition in Zambion hirtum shown in Fig. 35); 2) mesosoma completely yellow to orange (Fig. 46) (no dark colour).

Description

Adult. Female unknown.
Male: Fore wing length 5.8 mm. Clypeus separated from supraclypeal area by a strong groove. Malar space 0.4 times basal width of mandible. Supraclypeal area 1.7 times as wide as high, dorsomedially without a short, narrow, longitudinal lamella between the antenna. Supra-antennal horn moderately long and triangular in dorsal view (Fig. 47), about equal in length to width of pedicel at midheight in lateral view. Ocello-ocular distance 1.2 times ocellar diameter. Gena 0.8 times transverse diameter of the eye. Antennal flagellum with 32 segments.
Notaulus absent. Epicnemial carina mostly straight medially, not curving away from anterior edge of mesopleuron near ventral corner of pronotum (similar to Zambion rogeri shown in Fig. 32). Scutellum with lateral carinae extending 0.4 length of scutellum. Medial longitudinal carinae of propodeum complete and strong anterior to posterior transverse carina (as in Fig. 3). Carina extending from pleural carina to spiracle complete (Fig. 48). Posterior transverse carina of propodeum with lateral abscissa roughly straight, joining pleural carina at about 0.4 distance from posterior end of pleural carina to propodeal spiracle (Fig. 48). Ventral transverse carina extending from metasomal foramen to pleural carina absent (Fig. 48). Fore tibia with a moderately strong apical point on dorsal surface. Hind femur 3.6 times as long as medial width. Hind tarsal claw pectinate to about 0.5. Angulation of fore wing vein 2m-cu strong.
Tergite 1 of metasoma 1.6 times as long as apical width. Dorsal longitudinal carinae of T1 extending to spiracle (0.4 length of tergite), dorsolateral longitudinal carinae extending just over half way to spiracle (0.3 distance of T1).
Yellow. Legs and metasoma slightly darker yellow apically/ posteriorly. Vertex and supra-antennal area medially, scape and mesoscutum orange. Pedicel and apex of mandible dark brown. Flagellum medium brown except base of first flagellomere orange. Entire membrane of fore wing moderately infumate (Fig. 46). Body covered with dense golden setae.

Material examined

Holotype ♂, Label 1: KENYA: Rift Valley Province. Marich Pass Field Studies Centre, 1°32.2'N, 35°27.4'E, 13–14 June 2000. Label 2: M.H. Bourbin, V.H. Lee & W.J. Pulawski collectrs [CAS]. Condition: intact.

Etymology

This species is named in honour of Dr. Dmitriy Kasparyan (Zoological Institute, Russian Academy of Sciences, St. Petersburg) for his contributions to ichneumonid taxonomy especially being the first to recognize and describe the genus Zambion.
