Metanotum with longitudinally reticulate sculpture in middle, median pair of setae far behind anterior margin; distance between median pair of metanotal setae less than distance between median and submedian; campaniform sensilla present (
Fig. 7

Fig. 9
). Abdominal tergites with a few sculpture lines extending to median setae and campaniform sensilla; tergite II with 3 lateral marginal setae (
Fig. 8
); posterior margin of abdominal tergite VIII with complete and well-developed comb of fine microtrichia (
Fig. 4
); tergite IX with two pairs of campaniform sensilla, and S2 setae longer than S1 and equidistant from each other; tergite X longer than IX. Abdominal sternites with transverse lines of sculpture; sternites and laterotergites II–VIII without discal setae; sternite II with 2 pairs of posteromarginal setae; III–VII with 3 pairs of posteromarginal setae, median setae on VII far ahead of posterior margin (
Fig. 6
).

Etymology
. This species is named in honour of Dr Laurence Mound for his outstanding contributions to
thrips
systematics and for his untiring efforts in helping young
thrips
taxonomists.

Molecular data
. DNA barcode data of
holotype
and
paratype
of this species have been developed using the protocols published earlier (
Kumar et al., 2014
). The generated sequences were submitted to NCBI GenBank to get accession numbers (
KP993173
-
KP993174
) and BOLD (Barcode of Life Database) under the project titled “DNA Barcoding
Thrips
of
India
”.
Comments
: This species is close to
T. tanicus
,
floreus
,
formosanus
,
obscuripes
and
rostratus
with which it shares a similar body colour. It can be distinguished from
tanicus
,
floreus
,
formosanaus,
obscuripes
because they all have the following characters: tergite II with 4 lateral marginal setae; ocellar setae III either inside or touching the tangent at outer margin. Whereas in this new species tergite II has 3 lateral marginal setae, and ocellar setae III are clearly outside the ocellar triangle.
This species shares with
Thrips rostratus
the following character states: body colour, long mouthcone, ocellar III outside the triangle, median pair of metanotal setae far back from the anterior margin, and tergite II with 3 lateral marginal setae. It differs from
rostratus
by the presence of metanotal campaniform sensilla, yellowish brown antennal segment III, and clear area at base of dark fore wing. In contrast,
rostratus
has no metanotal campaniform sensilla, antennal segment III is dark brown and the fore wing uniformly dark.
