), broader in male (

); dorsum convex and glabrous. Dorsal side black except anterolateral borders of pronotum slightly paler. Ventral side black, mouthparts, antenna and legs yellowish testaceous, abdomen yellowish testaceous except abdominal ventrite 1 medially dark brown to black. Elytral punctation fine on disc, distinctly coarser and more closely spaced on lateral sides. Abdominal postcoxal lines (
Fig. 51e–g
) incomplete; posterior margin of ventrite 6 shallowly emarginate in male (
Fig. 51e
) and arcuate in female (
Fig. 51f
). Coxites (

Notes.
It was originally described from
Yunnan
,
China
. It is added to the
Indian
fauna of
Chilocorini
based on
three specimens
collected from Shillong in the north-eastern state of
Meghalaya
(
BMNH
, examined). These specimens bear the label “
Chilocorus
sp.
nr.
braeti
Ws.
, det.
R
.G. Booth, 1987”. The females are very similar to
C. braeti
in having a cordiform body outline, but
C. braeti
differs in having the elytra more distinctly narrowed towards the apices with much finer elytral punctation and the genitalia also are different.
Li
et al
. (2018)
treated this species in their revision of Chinese
Chilocorus
, but the habitus and male genitalia illustrations are not adequate to enable its unequivocal identification. Some specimens identified as ‘
C. braeti
’ in the collections of the Zoological Survey of
India
, Kolkata, appear to be misidentified and are likely to belong to this species.
