Chimarra mawsmaiensis

Diagnosis
: The male genitalia of this species is close to those of
Chimarra suadulla
Malicky & Chantramongkol 1993b
,
C. devva
Malicky & Chantramongkol 1993b
and
C. ravanna
Malicky & Chantramongkol 1993b
from
Thailand
in general appearance of genitalia, especially to
C. devva
and
C. suadulla
in dorsal view. However, in
C. mawsmaiensis
sp. nov.
the mesal lobes of tergum X are smaller than the sclerotized lateral lobes of tergum X in dorsal view (which are longer than lateral lobes of tergum X in dorsal view in
C. suadulla
). Moreover, the phallotremal sclerite complex is very long and triangular in ventral view in
C. mawsmaiensis
, whereas the phallotremal complex is smaller and fork-like in
C. devva
. In
C. suadulla
, the mesal lobes of tergum X are almost half the length of the lateral lobes in dorsal view, whereas the mesal lobes are almost equal to the lateral lobes of tergum X in
C. mawsmaiensis
. Moreover, there are clear differences visible in the shape, number and position of the endothecal spines and phallotremal complex of these latter two species.
Description
(male only): Length of each forewing 5.50 mm (n=10). Color in alcohol, entirely fulvous and body surface covered with dense, short and fulvous pubescence. Maxillary palps 1.45 mm long (n=10), segment 3 distinctly longer than 2, 3 subequal to 5; labial palpi 0.97 mm long (n=10). Forewing venation: Stem of Rs curved, with sclerotized node at inflection; fork at base of discoidal cell distinctly thickened, length of discoidal cell about 2.5 times width; crossvein

proximal to crossveins
s
and
r-m
; vein 2A intersecting 3A (
Figs. 44, 45
).
Male genitalia
(
Figs. 7–9
,
32–34
): Sternum VIII without posteroventral process. Segment IX with tergum short, forming narrow transverse bridge dorsally; anteroventral margin in lateral view bluntly produced and anterolateral margins deeply concave; posterolateral margins nearly smooth; short posteroventral process projecting posteroventrad. Inferior appendages slightly longer than tergum X, obliquely directed upward, apically rounded, each with curved apical spine; in ventral view broadly rounded laterally, inner margin almost straight, with apicomesal sclerotized tooth-like projection. Tergum X with sclerotized pairs of lateral and mesal lobes; lateral lobes each moderately long, in lateral view each with narrow apex, wedge-shaped, bearing multiple sensilla; mesal lobes elongate, digitate, directed posterodorsad. Preanal appendages setose, broadest basally in dorsal view. Phallic apparatus with sclerotized portion long, nearly cylindrical in lateral view (
Fig. 33
), phallobase tubular, without basodorsal expansion; phallotheca rounded apically; 3 slender, endothecal spines visible in lateral view distal of phallotremal sclerite; phallotremal sclerite very long, almost triangular in ventral view (
Fig. 34
); in lateral view with spine-like structure directed posterolaterad inside retracted phallotheca.
