Halyzia Mulsant

Genus Halyzia Mulsant

(Fig. 76)

Halyzia Mulsant, 1846: 141, 148.

Type species: Coccinella sedecimguttata Linnaeus, 1758: 367, by subsequent designation of Crotch 1874: 131.

Diagnosis. Medium to large sized beetles, coloration usually dull orange to straw yellow with other patterns or spots. Form broadly oval, moderately convex. Clypeal margin of head without distinct lateral projections. Mandibles apically multidentate, with a series of small serrations on apical ventral tooth, rarely bifid. Antenna (Fig. 76a) very long, loosely segmented, with 11 antennomeres, antennomeres 9–11 forming a loose club. Terminal maxillary palpomere (Fig. 76b) securiform, narrow basally, apical one-third widest. Terminal labial palpomere not as stout as preceding one. Anterior margin of pronotum barely emarginate, covering most of head at rest. Lateral margins of pronotum and elytra explanate. Prosternal carinae absent. Abdominal postcoxal line (Fig. 76c) usually very short, incomplete.

Affinities. Tomaszewska et al. (2021) included it under the Synonycha -group of genera and found all the genera of the former tribe Halyziini including Psyllobora, Oxytella, Illeis, Vibidia, Macroilleis, and Halyzia were grouped together and formed a major branch. The tribe Halyziini is now part of the composite Coccinellini as defined by Tomaszewska et al. (2021).

Included species. Six species are known from the Indian region of which H. feae Gorham 1895 (Type locality: Burma) is poorly known and Gorham’s description is indicative of an Illeis sp.
