Scirtidothrips Hood, 1954

( Figs 3–4 )

This genus comprises a single species, S. torquatus , described from Brazil but subsequently recorded from Costa Rica ( Mound & Marullo 1996). Although very similar to species placed in Scirtothrips in body form and the sculpture of the head and thorax, it differs in lacking microtrichia on the lateral sculpture lines of the tergites, the two dorsal setae on antennal segment II are sub-equal in length, the fore wing second vein bears a complete row of 16–17 setae, and the median two pairs of sternal posteromarginal setae arise submarginally at least on sternites V– VII. The figures given here ( Figs 3, 4 ) are from a female in the USNM collection, taken in January 1951 at Turrialba, Costa Rica, on Mimosa flowers and foliage, that has been studied together with the holotype female.
