Description
Redescription. Male: length: 11.2–13.6 mm, humeral width:
3.3–4.0 mm. Female: length: 13.5–17.5 mm, humeral width:
4.2–6.2 mm. Head black, with a “U” shaped macula formed by
dense yellowish white pubescence, additional yellowish white
spot of pubescence behind genae; antennae black, moderately
stout, longer than body in both male and female; antennomere
ratio: male: 16:4:24:20:20:18:18:16:15:14:15; female: 15:3:
24:19:19:18:18:16:15:14:15. Prothorax densely clothed with
yellowish white pubescence, with a broad black area on the
apical half of disc, maybe slightly narrowed medially (fi gs.
1–2); sides of prothorax with a moderate black spot adjacent
to coxae. Scutellum with yellowish white pubescence. Elytron
black with a broad pale, sinuate, sub-median transverse band of
yellowish-white pubescence extending from suture to the fi rst
lateral carina; and a second narrower preapical band of grayish
mesosternum, central part of metasternum, fi rst, second and
last abdominal segments black with short dark pubescence, rest
densely clothed with longer yellowish white pubescence.
Male terminalia (fi gs. 3-4): Tegmen length about 3.8 mm;
lateral lobes very slender, each about 1.4 mm long and 0.1
mm wide, apex with several short setae, with one small ridge
furnished with short and fi ne hairs at the base (in ventral view);
basal piece not bifurcated distally; median lobe plus median
struts slightly curved, shorter than tegmen (31: 38); the
median struts longer than half of the whole median lobe; dorsal
plate shorter than ventral plate; apex of ventral plate pointed;
median foramen moderately elongated, acute angle about 40
degrees; internal sac more than 3 times as long as median lobe
plus median struts, with 4 pieces of basal armature, 2 bands
of supporting armature and 3 rods; 2 longer rods each about
1.9mm, shorter than tegmen, the other shorter one about
1.3 mm. Tergite VIII slightly broader than long, apex almost
rounded, with moderately long setae at sides, shorter and sparser
in the middle. Ventrite IX subequal to ringed part of tegmen
in length. Female genitalia (fi g. 5): Spermathecal capsule
composed of an apical orb and a stalk, stalk twice as long as
apical orb. Tignum longer than abdomen. In our observation,
tignum 8.7 mm for an adult with a 6.2 mm abdomen in ventral
view.
Diagnosis. Diff ers from other species being considered as
morphs by Breuning in having the anterior male claw simple
and the apical visible ventrite in the male with a distinct umbo
prior to apical opening (fi gs. 2a, 2b), the elytral apex has longer
teeth.
Remarks. As far as we know, this species occurs in India,
Bhutan, Myanmar (Burma) (Carin Chebà), Nepal, Malaysia
and Indonesia (?only female specimens, so we are not so sure).
All the other distribution records, such as China, Vietnam,
Laos, etc, are due to misidentifi cations. Th us, the host plants
records become unreliable.
Distribution. Myanmar, India, Nepal, Bhutan, Malaysia (new
record), Indonesia (?).
