Genus Alloneda Iablokoff-Khnzorian

Alloneda Iablokoff-Khnzorian, 1979: 49 , 63.

Type species: Coccinella dodecaspilota Hope, 1831 (as Coccinella dodecastigma (sic) Hope), by original designation.

Diagnosis. Size medium to large, form broadly circular, dorsum hemispherical, strongly convex and glabrous. Anterior clypeal margin ( Fig. 20c ) straight between lateral projections. Antenna ( Fig. 20b ) 11-segmented, antennomere 1 enlarged in anterior half, antennomere 2 quadrate, 3–8 longer than broad, 9 little longer than wide, 10 transverse and terminal antennomere apically obliquely truncate. Pronotum with sides strongly rounded and slightly sinuate adjacent to anterolateral angles. Prothoracic hypomeron deeply foveate at anterior inner corners. Prosternal carinae ( Fig. 20e ) reaching up to middle of prosternal process, apically divergent. Anterior margin of mesoventrite ( Fig. 20e ) with a deep, V-shaped median emargination. Abdominal postcoxal line ( Fig. 20d ) incomplete. Elytral epipleura deeply foveate on level with hind coxae, inner carinae reaching elytral apex. Male genitalia with penis consisting of more than one sclerite that are distinctly separated by membranes.

Affinities. Tomaszewska et al. (2021) grouped Alloneda in the Synonycha -group of genera in their phylogenetic analysis. In their study, Alloneda formed a well-defined and supported clade with Coelophora Mulsant (part) and Propylea and shared many morphological similarities with Coelophora (part). Particularly, the male genitalia in Alloneda are similar to those of Coelophora in general and the lateral sides of the pronotum are slightly sinuate near the anterolateral angles in Alloneda and some species of Coelophora (e.g., Coelophora duvaucelii and C. decemguttata ).

Distribution. Asia (Indian Subcontinent; Southeast Asia. China).

Included species. Only Alloneda dodecaspilota (Hope) is known from this region at present. Yu (1998) provided a generic diagnosis and a key to the known species of Alloneda .
