Diagnosis.
Length: 4.00 mm; width:
3.70 mm
. Form nearly hemispherical, dorsum strongly convex and glabrous. Head and anterior and anterolateral corners of pronotum broadly reddish or yellowish testaceous, elytra black to piceous (
Fig. 31a, c
). Ventral side including legs yellowish testaceous except elytral epipleura largely blackish, inner side lighter. Outwardly similar to the more commonly collected
C. nigrita
but differs in possessing a narrow frons and divergent eyes, slender terminal maxillary and labial palpomere and elongate basal tooth of tarsal claw, and can be reliably separated mainly by the male genitalia (
Fig. 31e–g
).

Notes.
This is one of three known
Indian species
of the erstwhile
Phaenochilus
(now part of
Chilocorus
) with black to piceous elytra (
Giorgi & Vandenberg, 2012
). Following
Li
et al
. (2020b)
, it is transferred to
Chilocorus
(
comb. n.
). It may have a wider distribution in
India
, but likely to be misidentified as
Chilocorus nigrita
,
in view of its resemblance to the latter.
Miyatake (1970b)
described it from South
India
(
Tamil Nadu
) and it appears to be a rare species and it is also likely that specimens may be mixed up with
Chilocorus nigrita
,
a commonly collected species. Specimens from
Bihar
(BMNH, examined) identified as
Phaenochilus flaviceps
by R. G. Booth and P. Łączyński were also examined.
