Distribution
India
(
Bihar

Kerala
,
West Bengal
);
China
(
Fujian

, Guangdong,
Hong Kong
, Hainan, Yunnan) (
Rosa

). Widely distributed in the Oriental Region (
Kimsey & Bohart 1991
).
Remarks
Rosa
et al.
(2016)
considered
Trichrysis triacantha
as a possible synonym of
T. vestigator
(Smith, 1858)
based on illustrations of the apical margin of T3 provided by
Bohart (1988
: fig. 6) and
Kimsey & Bohart (1991
: fig. 150c). Thanks to the kind help of James Hogan (OUMNH), we examined pictures of the
type
of
T. vestigator
and can state that the two taxa are closely related. Actually, the intervals between the median tooth and the lateral teeth of the
type
specimen are straight and not convex, as shown in the illustrations of
Bohart (1988)
and
Kimsey & Bohart (1991)
. Taking into account the high variability of this species, as recorded by
Rosa
et al.
(2016)
, based on specimens collected in the same locality in
China
, we agree that the two species could be conspecific; however, examination of more material is needed prior to proceeding with this synonymy.
