Genus Adalia Mulsant

Idalia Mulsant, 1846: 44 . Type species: Coccinella bipunctata Linnaeus, 1758 (junior homonym), designated by Crotch 1874: 99.

Adalia Mulsant, 1846 : addenda et errata [p. 2] (replacement name); Gordon 1985: 776; Iablokoff-Khnzorian 1982: 429; Pope 1989: 648; Poorani 2002a: 320.

Diagnosis. Form elongate to short oval, dorsum weakly to moderately convex, glabrous. Anterior clypeal margin straight between lateral projections. Antenna short with a compact, three-segmented club. Scutellar shield small, triangular. Prothoracic hypomeron without foveae on anterolateral corners. Prosternal intercoxal process smooth, slightly convex, with weak lateral ridge extending anteriorly as far as anterior margin of coxa, not carinate. Anterior margin of mesoventrite barely emarginate, almost truncate. Middle and hind tibiae with a pair of apical spurs. Abdominal postcoxal line complete or nearly so, lacking an associate oblique line. Female genitalia with a conspicuous infundibulum.

Distribution. There are over 35 species of Adalia distributed worldwide ( Gordon 1985) and six species are known from the Palaearctic region ( Iablokoff-Khnzorian 1982).

Affinities. Tomaszewska et al. (2021) included Adalia in the Cycloneda -group of genera in their phylogenetic analysis and none of the other genera in this group is found in the Indian region.

Included species. This genus is represented by three species in the Indian subcontinent- Adalia simmondsi Kapur & Sudha Rao , A. tetraspilota (Hope) and A. bipunctata (Linnaeus) . All of them are confined to the coldest parts of north, northwestern and eastern Himalayan region of India and Pakistan.
