Lobobasis
Hampson
Type species: niveimaculata Hampson.
The genus is sexually
dimorphic, the males with the forewing costa rather angled subbasally, with
dense ochreous (on the costa) and rusty scales surrounding the basal white patch
and obscuring the area of the central costal white triangle of the female. The
hindwing costa is also modified, folded under to cover a patch of androconial
scales; it is thus much deeper than that of the female. These features and the
venation are illustrated in Fig 6e.

The male abdomen is typical
of the generic complex, but is distinguished in the genitalia by the presence of
sclerotised extensions on each side of the aedeagus apex that bear clumps of
long spines. These presumably engage with a pair of heavily sclerotised grooves
in the neck of the bursa distal to the broad, trapezoid ductus that is shaped
and ornamented somewhat as in Padenia.
The genus contains one very
widespread species.
