Isoneurothrips parvispinus Karny 1922: 106

This polyphagous oriental species has been studied from La Réunion ( Bournier, 2000) and also from Mauritius, and is likely to be present on the African continent.

Diagnosis. Brown, head and thorax paler than abdomen, legs mainly yellow; antennal segment III yellow, also basal half of IV–V; forewings brown with base sharply pale. Antennae 7-segmented. Ocellar setae III small, on anterior margins of triangle; postocular setae pair II minute. Pronotum with 2 pairs of long posteroangular setae. Metanotum variably reticulate, sometimes with faint internal markings ( Fig. 38 ); median setae long, arising behind anterior margin; campaniform sensilla absent. Forewing first vein with complete row of setae. Tergite VIII comb almost absent, a few microtrichia sometimes laterally; pleurotergites without discal setae; sternites III–VI with 6 to 12 discal setae in irregular row, sternites II and VII without discal setae ( Fig. 39 ).
