Plicothrips Bhatti

Plicothrips Bhatti, 1979: 306 . Type species Hindsiana apicalis Bagnall , by original designation.

This genus was erected for two species, the second being Haplothrips cameroni Priesner , in both of which the epimeral (5notopleural) sutures are incomplete and each abdominal tergite bears only one pair of sigmoid wing-retaining setae. Moreover, the wings of macropterae are not constricted medially, but are narrowed following the basal one-third. The two species involved both live on Cynodon dactylon , between Sudan and Thailand, and despite slight differences in the colour of their antennae, they probably represent a single species.

Plicothrips apicalis (Bagnall)

Hindsiana apicalis Bagnall, 1915: 323 .

This species was recorded from Iran by Alavi and Kamali (2003) from Bojnourd (Khorasan Province) taken on leaves of Cynodon dactylon .

Diagnosis

Bicoloured, yellow except head, antennal segments I, II and VI–VIII, pterothorax, anterior third of abdominal segments II–VII, abdominal segments VIII–X, and mid and hind tibiae brown; prothorax, forelegs and mid and hind femora yellow-brown. Forewings clear. Postocular setae shaded, pronotal setae as well as sub-basal wing setae pale, tergite IX setae and anal setae weakly shaded. Antennal segment III with one sensorium (cf. Figure 28 ), IV with four; postocular setae expanded apically; pronotal antero-marginal and mid-lateral setae well developed and expanded apically; mesopresternum eroded medially (cf. Figures 1 , 13, 14 ); micropterous, brachypterous, or macropterous, forewings without duplicated cilia; sub-basal wing setae S3 shorter than S2, S1 usually as long as S3. Pelta triangular (cf. Figure 16 ); abdominal tergites III–VI with only one pair of sigmoid setae; tergite IX setae S1, S2 and S3 pointed, S1 and S2 subequal; S1 on other tergites capitate. Tube short (cf. Figure 31 ), twice as long as basal width at most; anal setae about 1.5 times as long as tube.
