Karnyothrips flavipes (Jones)

Remarks.

This is one of the most commonly collected Phlaeothripidae on the Hawaiian Islands, where it has been taken widely, living on dead branches and twigs. Although common and widespread on the islands, it is rarely found in large numbers, a characteristic that agrees with its habits as a predator of other small arthropods (Jaramilo et al. 2010). Small and dark brown, with a slightly elongate head (Fig. 12), it is usually recognisable from the slightly yellow colour of antennal segment III, and the hind tibiae that are yellowish on at least the distal half. The number of antennal sense cones varies in this species, with segment IV bearing either three or four, although segment III consistently bears two sense cones ( Okajima 2006). The fore tarsus bears a prominent curved tooth at the inner apex (Fig. 12), and the major setae S1 and S2 on tergite VIII are capitate, as is S1 on the ninth tergite.
