Lyclene obscurilinea sp.
n.
Asura sp.
3 (part) of Holloway, 1976: 3, Fig. 13, plate 1:13.
11-13mm,
13-14mm. This
species is the first of a sequence of four that are probably most closely
related to obliquilinea Swinhoe comb. rev. (N.E. Himalaya), as the
forewing facies is similar: a set of basal streaks enclosed by a generally
oblique but sometimes angled subbasal fascia; a deeply zig-zagged postmedial; a
submarginal row of streaks; a slight row of dots on the veins at the margin. The
distal half of the male abdomen is grey-brown, and the abdomen has coremata well
developed. The genitalia also indicate close relationship amongst at least three
of the four Bornean species. The distal processes of the valve are stronger than
in obliquilinea and the vesica has two rows of short, robust Barsinelike
cornuti, the more distal one with far fewer than the basal one; in obliquilinea
there is a single tight cluster of four narrower, longer spines. The female
of obscurilinea has an elongate ductus, a curvature to the neck of the
bursa, often with a globular subbasal swelling, and a broader distal section;
the curved section may be more sclerotised. In obliquilinea the bursa is
coarsely spined virtually throughout, and has longitudinal bands of
sclerotisation that are also spined. In obscurilinea the forewing
markings are often obscured by a general basal and postmedial area of brownish
suffusion. The subbasal line is oblique, not distinctly angled, though curved
basad at each end slightly, and encloses only two strong streaks. In the male
genitalia the costal and saccular processes are blunt, incurved, but the valve
apex extends beyond them. The aedeagus vesica is very deep, with a spherical
lobe opposite the part with the cornuti; these are relatively small. The female
has a globular subbasal swelling to the neck of the bursa but the neck curvature
is slight and the distal part of the bursa is narrow.
