( Fig. 121 )

Illeis koebelei Timberlake, 1943: 44 (Type locality: Japan).— Poorani 2002: 334.

Diagnosis. Length: 3.50–5.10 mm; width: 3.10–4.00 mm. Form elongate oval, dorsum moderately convex and glabrous. Dorsal side uniform yellow with a pair of oblique oval black spots on posterior margin of pronotum above scutellar shield ( Fig. 121a, b ). Externally similar to other Illeis spp. of the region and appears to be closest to I. indica in having a distinctly elongate form. It can be reliably identified only by the male genitalia ( Fig. 121c–e ).

Distribution. India (Assam); Japan; China; Taiwan.

Notes. The illustrations given here are based on the material examined at BMNH. See Timberlake (1943), Bielawski (1961a) and Ren et al. (2009) for more detailed description and / or illustrations of the male genitalia.
