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