Habrothrips Ananthakrishnan

Habrothrips Ananthakrishnan, 1968: 137 . Type species Habrothrips curiosus Ananthakrishnan.

The single species in this genus is widely distributed in leaf-litter between India and northern Australia, and all known specimens of both sexes are macropterae ( Figs 39–40 ). It shares with other urothripine species the long abdominal segments IX–X and the presence of a pair of prominent setae on the metathoracic epimera, but it exhibits several unusual features. The following can probably be considered plesiomorphic: compound eyes large and globose, mid and hind tarsi 2-segmented, and fore tarsal hamus directed ventro-medially. However, the following character states are more highly derived, and are unique among urothripines: head strongly projecting in front of eyes, and abdominal tergites with a median groove bearing two pairs of leaf-like setae that are presumably wing-retaining.
