Karnyothrips Watson

Karnyothrips Watson 1923, p 23 . Type species: Karynia weigeli Watson.

This poorly defined genus currently includes 45 species, of which 30 are from North, Central or South America ( Mound and Marullo 1996), with one from Ghana, three from India, two from the Philippines, and nine from Japan ( Okajima 2006). Two species are widespread around the world, including Australia, and both of them have many synonyms. These two species are known to be predatory on scale insects ( Palmer and Mound 1990), and other members of the genus possibly have a similar biology. Karnyothrips is currently considered polyphyletic, and there is no satisfactory definition of the genus. The included species are very similar to Haplothrips species , but usually have the fore tarsal tooth projecting forwards from the anterior margin of the tarsus ( Figure 6 ), the prosternal basantra usually slightly longer than wide, the pronotal anteromarginal setae no longer than the discal setae, and the anal setae twice as long as the tube. In both species considered here, antennal segment III bears two small sensoria and segment IV bears three or four.
