Chilocorus albomarginalis (Li & Wang) , comb. n.

( Fig. 23 )

Phaenochilus albomarginalis Li & Wang , in Li et al. 2017b: 35 .

Chilocorus albusolomus (sic): Li et al. 2020a: 11 (misspelled).

Diagnosis. Length: 3.67–3.80 mm; width: 3.60–3.67 mm. Form broad oval, dorsum strongly convex and glabrous; dorsal and ventral sides yellowish, elytral margins whitish and distinctly paler than disc ( Fig. 23a–c ). Elytra with lateral sides somewhat subparallel for nearly two-thirds of the length. Abdominal postcoxal lines incomplete, ventrite 6 posteriorly distinctly and deeply emarginate ( Fig. 23d ). Male genitalia with penis guide ( Fig. 23e, f ) asymmetrical, parameres subequal to or slightly shorter than penis guide, with characteristic, long and dense pubescence on outer and apical margins; penis ( Fig. 23g ) with inner process of capsule more slender and longer than outer process, apex ( Fig. 23h ) modified as illustrated.

Distribution. India (Assam) (new record); China (Yunnan).

Material examined. INDIA: Assam, Margherita , 163.5 mts, 27°15’47.4”N 095°41’59.8”E, 14.ix.2014, Sweep net, Yeshwanth, H.M. / genitalia in glass vial pinned to specimen ( NCBS) .

Notes. This species was originally described under Phaenochilus by Li et al. (2017b) from Yunnan, China and it is transferred to Chilocorus (comb. n.) following the revised phylogenetic classification proposed for Chilocorini by Li et al. (2020b). The species included as “ Chilocorus albusolomus (Li &Wang, 2017) ” by Li et al. (2020a) apparently refers to P. albomarginalis and “ Chilocorus albusolomus ” looks like a lapsus calami and not mentioned anywhere else, including Li et al. (2017b), cited as the original source of this name.
