Garella Walker

Type species: rotundipennis Walker, Borneo.

Corticata Walker (type species scoparioides Walker, Borneo) syn. n.; Dendrothripa Hampson (type species rufipuncta Hampson, India); Hypothripa Hampson (type species curiosa Swinhoe, Burma) syn. n.; Paraxia Möschler (type species chamaeleon Möschler = nilotica Rogenhofer, Puerto Rico) syn. n.

Garella species are very similar to those of typical Characoma in facies and venation; the hindwing is trifine. They are distinguished by several features of the male and female genitalia.

The male abdomen has a tymbal organ in the type species and allies, but not always. The genitalia have the uncus slender, but apically bilobed, and usually flanked on the scaphium by unusual pads of setal bases (the setae are easily detached; this feature is absent from the widespread G. nilotica Rogenhofer comb. n. and the Australasian G. vallata Meyrick comb. n.). The tegumen, when ventrally expanded at the junction with the vinculum (not in G. scoparioides Walker comb. n.), supports a hair pencil at that point. The black-scaled process of the valve is short and globular rather than blade-like.

The female genitalia have acute ovipositor lobes as in the Characoma complex, but differ from it in having a distinct signum or signa in the bursa rather than general spining.

The extent of the genus needs further study, particularly outside the Indo-Australian tropics, but probably most Indo-Australian species are identified in this account.
