Bregmatothrips Hood

With one new synonym recognised below, together with one newly described species, this genus now includes a total of nine species, all of which apparently breed on grass leaves. Four described species are currently considered synonyms of the type species, B. venustus . These are all from the southern Nearctic, and venustus is one of only two species in the genus that has a single dorso-apical seta on the first antennal segment. In contrast the other seven members of the genus all have two setae in this position. These seven are all from the Old World: one is from southern Europe, with others described from Iran, Egypt, Cape Verde Islands, and South Africa, also two from Asia of which one is known from tropical Australia. Bhatti (1984) distinguished two groups among the members of this genus, but the new species described below includes character states from both of these groups. No key to identify the members of this genus is available, therefore a key to world species is provided here as an Appendix (page 40).
