Eugynothrips Priesner

(Figs 14, 126)

Eugynothrips Priesner, 1926: 157 . Type species: Cryptothrips conocephali Karny, by subsequent designation.

This South East Asian genus is a member of the Liothrips- lineage. It comprises 16 leaf-feeding species, of which four are placed in the subgenus Loepothrips . One species was described from India, but all the others from Indonesia, either Java or Sumatra, with a single species, intorquens (Karny), recorded from southern Japan and Taiwan (Okajima 2006). One un-named species has been seen from mainland China (NZMC, Beijing). Species in this genus usually have the head relatively short (Fig. 126) and the antennal sensoria unusually long (Fig. 14). However, most of these species were described 100 years ago from poorly mounted specimens, and the group requires extensive study.

Diagnosis: Head a little longer than wide (Fig. 126); eyes normal, without enlarged ommatidia, postocular setae either small or well-developed; stylets retracted to postocular setae, wide apart; antennae 8-segmented, III with 1 sensorium, IV with 3, sensoria long and slender (Fig. 14); pronotum with major setae developed, sometimes am reduced, notopleural sutures usually complete; basantra absent; mesopresternum reduced medially; sternopleural sutures present, but short; fore tarsal tooth absent in female, present in male; fore wings parallelsided, with duplicated cilia; pelta triangular; tergites II–VII with 2 pairs of wing-retaining setae; tube with straight sides, slightly shorter than head; male sternite VIII without pore plate.
