Eurhynchothrips Bagnall

( Figs 13 , 36, 37 )

Eurhynchothrips Bagnall, 1918: 213 . Type species: Eurhynchothrips convergens Bagnall , by monotypy.

Of the five species listed in this genus, three are known only from West Africa. One species, ordinarius (Hood) from India, is recorded from China ( Han 1997), and messuicola (Bagnall) described from Malaysia has been seen from Singapore. This is yet another poorly defined genus in the Liothrips- lineage.

Diagnosis: Head slightly longer than wide; eyes normal, postocular setae well-developed; stylets retracted to compound eyes, less than fifth of head width apart with stout maxillary bridge ( Fig. 37 ); antennae 8-segmented ( Fig. 13 ), III with 1 sensorium, IV with 3; pronotum with 5 pairs of developed setae, notopleural sutures complete; basantra absent; mesopresternum transverse but slender; sternopleural sutures present ( Fig. 36 ); fore tarsal tooth absent in both sexes; fore wings parallel-sided, with duplicated cilia; pelta broadly triangular; tergites II–VII with 2 pairs of wing-retaining setae; tube with straight sides, shorter than head; male sternite VIII without pore plate.
