Urothrips Bagnall

( Fig. 33 )

Urothrips Bagnall, 1909: 126 . Type species: Urothrips paradoxus Bagnall , by monotypy.

In describing a new species from the Seychelles, Ulitzka and Mound (2014) placed as new synonyms of Urothrips the two generic names Coxothrips Bournier from Africa and Asia, and Biconothrips Stannard from Australia. There are now nine species listed in this genus, of which two are recorded from China by Dang and Qiao (2012) under the name Coxothrips , and a third species is known only from Thailand (Okajima & Urushihara 1995).

Diagnosis: Head longer than wide, slightly to strongly produced anteriorly, sometimes produced as a hump ( Fig. 33 ); without prominent setae on vertex; eyes reduced to few distinct facets; all head setae small, usually arising from tubercles; stylets retracted to eyes, wide apart; antenna 5–8-segmented, segments III–V sometimes fused, VII–VIII sometimes fused with or without a distinct suture, sensoria on III–IV various; pronotum with irregular sculpture and numerous tubercles, most setae small and pointed, epim enlarged or blunt, notopleural suture reduced; basantra reduced or small; mesopresternum developed; fore tarsus usually with a hook-like hamus; usually apterous; pelta distinctly separated from tergite II or not; tergites reticulate strongly or weakly; setae usually small, posterolateral setae on III–VIII enlarged or blunt at tip; tergites without sigmoid wing-retaining setae; segments IX–X elongate, with 3 pairs of anal setae subequal in length.
