Nicevillea Hampson
Type
species: epiplemoides Hampson,
Burma.
The only
species in the genus is slender, delicate, with long, filiform antennae,
strongly fasciculate in the male. All the wings have a central angle to the
distal margin, and the hindwing has the section from this angle to the tornus
distinctly scalloped. The legs are also long and slender, straw-coloured except
for conspicuous tufts of greyish scales at the joints. The facies is also straw-coloured,
with a darker, pinkish violet tint distal to the fine, narrow postmedial fasciae
of the same colour. The tornal area of the hindwing has some lunules or patches
of ground colour within the darker margin. The second abdominal tergite lacks
phragma lobes.
The male
abdomen has the eighth tergite heart-shaped, with a pair of long, slender
apodemes running forward close together from the point of the heart. The
sternite forms an elongate, rounded-rectangular frame, with lateral ‘wings’
anteriorly; the frame does not appear to support a corema. The genitalia are
very narrow and elongate as illustrated, particularly the valves which are
ornamented over their length with short, robust setae that broaden apically into
fan-like structures. There is also a bundle of robust, spine-like setae
subbasally on the costa. The structure is reminiscent of that seen in some
ariolicine Nolidae.
In the
female genitalia the ostium is set within the eighth segment and is narrow as is
the moderate, sclerotised ductus that becomes more membranous and constricted
before it opens out into the irregularly pyriform bursa that has an irregular
but robust zone of sclerotisation in its basal neck.
