Distribution.
India
: Karnataka (
Anwar
et al.

), Manipur (new record).
Remarks.
No significant variation (besides the normal sexually dimorphic features of antenna and genitalia) was noted among the four females and five males collected in Manipur, all from the same locality and date.

Discussion
. All measurements of a single male of
S. indica
described by
Anwar
et al.
(2014)
match those of the five males we collected from Manipur along with four females, except for a few corrections to their description (when we measured the
holotype
): the mesosoma is 2.06× the gaster length (not 0.68× as mentioned in the original description), and the longest marginal seta of fore wing is 4.3× maximum wing width (not 5.0× as indicated in the original description). Sculpture of the head and mesosoma of the five males and four females reported here is also similar to that of the
holotype
of
S. indica
.
We therefore conclude that these belong to the same species,
S. indica
, even though they are recovered from a geographically different place within
India
.
