The species is characterized by absence of seta sd4 and additional seta d6 on head, absence of seta P1a on abdominal tergites I-VI, presence of seta Pc on sternite VII, short sensillum a reaching to the base of sensillum t2, long foretarsal sensilla b and f, sensillum c shorter than b, short and slender sensilla a', b' and c', and presence of psl pores on tergite VI only.
Abdomen: Male broad bands,black bars straight fronton edge of tergites 3and 4; 25% of lateral margins yellow; sternites reduced
in having female metasoma consisting of only two tergites, the petiole and a large fused one (approaching appearance of metasoma of Holocoeliella Huggert, 1981; but the latter has Platygaster-like mesosoma).
Abdomen: The median ridge of the thorax continues along the tergal plate of mtg III-VI, lateral sclerites with punctured oval depressions; deltg II + III not fused, anteriorly reaching to pronotum, lateral margins of deltg II-VII reflexed with posterolateral hairy tubercles; tergite VII elevated with 2 vertical projections.
Shagreen absent on tergite I, dense on tergite 11, and sparse on tergites III-IX; spinules 3-5 long, arranged in transverse rows on tergite II, and 1-2 long, arranged solitary on tergites III to anal lobe (Fig.
1); posterior margins of tergites reddish-brown; proximal urogomphus with pronounced reddish-brown basal band, narrow less intensely pigmented band distally on some specimens.
These hemisegment preparations were then further cut into pieces of two consecutive tergites each.
Microtrichial fields present on lateral thirds of tergites (white arrows) (adult Scirtothrips dorsalis).
