Calvia albida Bielawski

( Fig. 30 )

Calvia albida Bielawski, 1972: 308 (Holotype male, ZSBS; Type locality: Nepal).—Booth 1997: 931; Poorani 2002a: 322; Ren et al. 2009: 180; Yu 2010: 49.

Halyzia maculata Jing, 1987: 201 .—Synonymized by Yu 2010: 49.

Diagnosis. Length: 7.00– 7.50 mm; width: 6.00– 6.50 mm. Form ( Fig. 30a, b ) elongate oval, dorsum moderately convex, glabrous except head with silvery white hairs. Ground colour lime green to yellowish green in live specimens, pronotum with an indistinct, M-shaped brown marking, elytra mottled with creamy white spots. Prosternal process convex, without carinae. Spermatheca ( Fig. 30c, d ) as illustrated, with a bulky cornu. Its green colour with a mottled elytral pattern is similar to that of Calvia explanata Poorani , from which it can be distinguished by its distinctly elongate oval form and the genitalia.

Distribution. India: Northeastern region (Arunachal Pradesh, Manipur, Sikkim, Uttarakhand, West Bengal); Nepal; Bhutan; China.

Prey/associated habitat. Aphididae : Mollitrichosiphum alni Ghosh et al. on Indian alder ( Phaloura & Singh 1991); Vesiculaphis (data label) (Booth 1997).

Seasonal occurrence. Collected in April, August and November (label data).

Notes. Bielawki (1972) described it from Nepal. Booth (1997) included it in his key to Indian Calvia spp. Yu (2010) recorded it from China and illustrated it.
