Chimarra rongliensis
sp. nov.
(
Figs.1–3
,
26–28
,
50–51
)
Diagnosis
: The genitalia of this new species closely resemble those of
Chimarra atara
Malicky & Chantaramongkol 1993b
from
Thailand
and
C. supanna
Malicky 1993
from Sumatra. It is closer to
C. atara
in the shape of segment IX in lateral view. However, the anteroventral margin of segment IX is produced in
C. atara
whereas it is not produced in
C. rongliensis
in lateral view. The mesal lobes of tergum X are not curved backward apically in
C. atara
as they are in
C. rongliensis
.

Description
: Length of each male forewing 7.00 mm (n=1) and female forewing 9.25 mm (n=2). Body in alcohol entirely fuscous and covered with inconspicuous, sparse and fuscous pubescence. Length of each antenna 5.52 mm (n=2); maxillary palps each 1.78 mm long (n=2), segment 3 slightly longer than 2, 3 subequal to 5 and each labial palp 0.97 mm long (n=2). Forewing venation: stem of Rs curved, with enlarged node at inflection; fork at base of discoidal cell distinctly thickened, length of discoidal cell about 2.5 times width; crossvein
m
proximal to crossveins
s
and
r-m
; vein 2A intersecting 3A (
Figs. 50, 51
).
Male genitalia
(
Figs. 1–3
,
26–28
): Tergum IX short dorsolaterally, obsolete and membranous dorsomesally, anteroventral margin in lateral view not produced, posteroventral margin distinctly produced; ventral process rudimentary. Inferior appendages each slightly longer than tergum X; in lateral view placed obliquely, uniformly wide, apically blunt; in ventral view proximal ¾ straight, apical ¼ curved mesad. Tergum X with sclerotized lateral and mesal lobes, each lateral lobe in lateral view subovate, broad, apically slender and curved backward, bearing multiple sensilla; each mesal lobe elongate, digitate and curved apically. Each preanal appendage setose, broad and semicircular. Phallic apparatus with sclerotized portion long, nearly cylindrical in lateral view (
Fig. 26
), with tubular phallobase, without any basodorsal expansion, ventral apex weakly sclerotized; endotheca without small endothecal spines inside retracted phallotheca; 2 long spines and single, very thick spine curved and pointed at apex, visible apically in phallotheca in ventral view (
Fig. 27
); phallotremal sclerite complex not visible in any view; phallotheca bifid apically.
