Family: UZELOTHRIPIDAE

 

Only one species is included in this family. The structure of the forewings, antennae and female ovipositor are unlike that of any other Thysanoptera.

Uzelothrips scabrosus Hood

Available names: Original name Uzelothrips scabrosus Hood, 1952.


Biology: Presumably fungus feeding, having been taken in large numbers from dead twigs and in leaf litter.


Distribution: southern Brazil, and Singapore.


Recognition: Minute, brown, and usually wingless, antennae exceptionally long and slender, segment III with a circular sensorium ventrally near apex. Forewing when present with no longitudinal veins, marginal cilia arising from sockets. Wingless female with eyes reduced to about 4 facets, head much wider than long; pronotum trapezoidal, posterior angles elevated and bearing 2 pairs of short broadly capitate setae. Posterior margin of pronotum, mesonotum, metanotum and tergites I to VIII bearing row of narrow lobes.


Related species: Only one species is known in this genus. Superficially this looks like a member of the Thripidae genus Kurtomathrips, with a small transverse head, trapezoidal pronotum, and lobed posterior margins to the tergites. However, the antennal structure is unlike that of any other thrips.


Generic relationships: It is not possible to suggest any relationships between Uzelothrips and any other genus of Thysanoptera.
