Chirothripoides Bagnall

This genus can be characterised as follows ( Okajima 1981; Bhatti 1998a, b). Head longer than broad, distinctly produced in front of eyes; maxillary stylets short; mouthcone short and rounded; postocular setae minute; eyes large. Antennae 8- segmented, III and IV each with 2 stout sense cones. Pronotum without long setae, weakly sclerotised, anterior margin irregular. Basantral plates absent or reduced. Ferna with two widely spaced sclerites, distance between them about threefourths of their width. Postferna well developed as a transverse sclerite. Prospinasternum without spina. Pterothorax elongate. Mesoacrotergite complete and narrowed at middle. Mesopraesternum absent. Meso- and metasternum with long seta on either side, as long as or longer than width of sternum. Fore coxae elongate; fore tibiae with or without tooth; mid tibiae with one, hind tibiae with 2 spur-like setae. Fore tarsi 1-segmented, mid and hind tarsi either 1- or 2- segmented. Fore wings long and slender, parallel sided, with few duplicated cilia. Abdominal tergites without wingretaining setae; sternite VIII posterior margin with long teeth, lateral and median pairs stouter than others; tube shorter than head; anal setae shorter than tube.

This genus is close to Adamantothrips and Lonchothrips but can be distinguished from these as follows: Adamantothrips shares all the characters of Chirothripoides except that the tube is swollen. Lonchothrips has the mesoacrotergite divided into two broadly separated sclerites ( Bhatti 1998a), antennal segment II is forwardly extended, and the posterior margin of sternite VIII lacks projections.
