species: nigraericta Swinhoe.
monobasic genus is superficially similar to Ugia in
appearance, except the male antennae are ciliate and the third segment of the
labial palps is relatively much shorter; the palps, ventral part of the head and
prothoracic legs are distinctly darker than the wings. An oblique double fascia
runs from the apex of the forewing to continue across the dorsum to the hindwing,
but it is in a more distal position than in Ugia and does not have an angle to the
inner component anteriorly on the forewing. There is no submarginal marking. See
also the species description below.
abdomen has an eighth sternite of the framed corematous type with lateral rods.
The tergite has slightly splayed apodemes and is relatively broad, but tends
towards the condition seen in genera with the framed sternite. The genitalia
have the uncus robust, but there is no scaphium. The ventral ends of the tegumen
have spined, tongue-like lobes. The valves are also narrow, tongue-like, with
small subapical coremata and a central tongue arising from the base. The juxta
is unusually furcate, the arms of the furca splayed, arising adjacent to the
base of the sacculus on each side. The aedeagus is small, the vesica simply
genitalia of the only female available were somewhat damaged and invested with
mould. The ostium is associated with the anterior of the eighth segment. The
ductus and bursa are unsclerotised, the former, or the neck of the latter
basally, rather sinuous. The seventh sternite is only slightly reduced relative
to the tergite.
