Diagnosis. Apterous, anterior margin of head without prominent setae but sometimes produced over base of antennae; eyes reduced to about 10 ommatidia; all head setae small; stylets retracted to eyes, one-third of head width apart; antenna 8-segmented, but variously reduced to 5 visible segments due to fusion between different segments, III with 1 sensorium, IV with 2; pronotum transverse, setae small and pointed, epimeral setae larger, notopleural sutures not present; basantra absent; mesopresternum variable; fore tarsus usually with hook-like hamus on external margin; mesothorax swollen laterally, hind coxae further apart than mid coxae; pelta fully transverse, indistinctly separated from tergite II; tergites strongly sculptured, setae small, without wing-retaining setae; segments IX–X elongate much longer than VIII; anal setae usually longer than tube.

Comment. With the description of the new species below, the genus Urothrips now includes nine species (Table 1), all from the Old World. This genus shares most character states with the New World genus, Trachythrips Hood, but species in that genus have distinctive, fully transverse, prosternal basantra.
