Diagnosis.
The new species is similar to
S. xanthomochla
Meyrick,
1913
in the forewing pattern. It can be distinguished in the male genitalia by the apex-pointed gnathos 1/3 the length of the uncus, the short digitate inner process of the valva, and the cucullus narrowed to an obtuse apex. In
S. xanthomochla
, the apex-straight gnathos is the same length as the uncus, the inner process of the valva is elongately spine-shaped, and the cucullus is subrectangular.
Description.
Adult (
Fig. 3
). Wingspan 9.5‒10.0 mm. Head with frons pale brown; vertex dark brown; occiput blackish grey. Labial palpus yellowish white on inner surface, second segment brown and third segment dark brown on outer surface. Antenna blackish brown. Throax and tegula blackish grey. Forewing dark bronzy, with two yellow fasciae reaching below costal margin: antemedian fascia at basal 1/4, edged with dark brown scales; postmedian fascia at basal 2/3, with a rectangular dark brown streak on inner margin; fringe dark brown. Hindwing and fringe brown. Foreleg blackish brown on outer surface, greyish white on inner surface; midleg greyish white, tibia black at base, middle and apex respectively, with long dark brown bristles at middle and apex, tarsus blackish brown dorsally; hindleg greyish white, tibia blackish brown at base, middle and apex, with long dark brown bristles at middle and apex, tarsus with long dark brown bristles at apices of basal two tarsomeres, second tarsomere blackish brown. Abdomen dark brown on dorsal surface, grey on ventral surface.
Male genitalia (
Fig. 27
). Uncus wide at base, narrowed to apex, with long setae laterally, apex hooked in lateral view. Gnathos sub-triangular, wide at base, abruptly narrowed to pointed apex, 1/3 length of uncus (
Fig. 27a
). Tegumen broad, height 1.2 times length of uncus, produced to a rectangular process anterolaterally. Valva with costa subrectangular; inner process short, digitate; cucullus elongate, length three times of maximum width, broad at base, narrowed to rounded apex, obliquely curved dorsoapically, androconia arranged elliptically, running from base to 1/4 length of cucullus ventrally; sacculus wide at base, narrowed to apex, slightly concave medially on ventral margin, with long setae distally, free from valva just before narrowly rounded apex. Vinculum narrowly banded; saccus produced conically, 1/5 length of uncus. Juxta widely U-shaped, anterior margin produced medially; anellar lobes sub-conical, rounded apically, with long setae. Aedeagus 3/4 length of valva, basal 3/4 almost uniformly wide, distal 1/4 slightly narrowed; cornuti consisting of a tuft of short spines, a S-shaped needle between basal 1/4 and middle, and a long spine from middle to distal 1/4.
