Prosantothrips Priesner
Prosantothrips Priesner, 1952: 199 . Type species: Eothrips hyalopterus Karny, by monotypy.
This genus was erected for a single species from Vietnam. Two females and one male from the type series have been studied, although some characters are not easily seen on these specimens. The presence of two sensoria on the third antennal segment suggests that this species is not a member of the Liothrips- lineage, in contrast to the type species of Eothrips . Priesner mentioned the “strongly sclerotised tube” as indicating a relationship to Acallurothrips in the Idolothripinae . However, as is clear from the diagnosis given below, most of the character states suggest that this species is related to Liothrips .
Diagnosis: Head slightly longer than wide; eyes normal, postocular setae well-developed and wide apart; stylets retracted to postocular setae, V-shaped; antennae 8-segmented, III with 2 sensoria, IV with 3; pronotum with 4 pairs of well-developed setae, am minute, notopleural sutures complete; basantra absent; mesopresternum transverse; sternopleural sutures well-developed; fore tarsal tooth absent in both sexes; fore wings broad, parallelsided, with duplicated cilia; pelta nearly 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.
