Chimarra rifati
sp. nov.
(

,
40–41
,
54–55
)
Diagnosis
: In having long hairs on the inferior appendages and the shape of segment IX in lateral view this species resembles 3 Bhutanese species (
Chimarra semiramis
Malicky 2007
,
Chimarra pontos
Malicky 2007
,
Chimarra oreithyia
Malicky 2007
), a Vietnamese species (
Chimarra haimuoi
Malicky 1995
) from
Vietnam
and 2 species from
Thailand
(
C. scopulifera
Kimmins, 1957
,
C. lahuorum
Malicky & Chantramongkol, 1989
). But it is more closer to
C. scopulifera
in dorsal view. However, small postventral process (in lateral view), postventrad curved sclerotized lateral lobes of terum X (in lateral view) and digitate and narrow mesal lobes of tergum X (in dorsal view) in
C. rifati
whereas, broad postventral process, straight posteriorly directed sclerotized lateral lobes of tergum X (in lateral view) and mesal lobes of tergum X are broad at base in
C. scopulifera
makes
C. rifati
as distinct species.
Description
(male only): Length of each forewing 6.50 mm (n=1). Color in alcohol entirely fulvous except legs fuscous and body covered with inconspicuous, sparse and fulvous pubescence. Maxillary palps 1.46 mm long (n=1), segment 3 slightly longer than 2 but subequal to 5; labial palps 0.65 mm long (n=1). Forewing venation: stem of Rs curved, slightly sclerotized and thickened at inflection; fork at base of discoidal cell distinctly thickened, length of discoidal cell about 3 times width; crossvein

and

; vein 2A not intersecting 3A.

Male genitalia
(
Figs. 20–22
,
40–41
): Segment IX subtriangular in lateral view, long laterally and especially ventrally, obsolete and membranous dorsomesally; posteroventral process evident. Inferior appendages obliquely extending to tip of tergum X, densely covered laterally with very long setae; in lateral view, nearly uniformly wide with dorsal apex bluntly pointed, in ventral view outer margin arched, inner margin broadly concave near middle, apex with mesally directed tooth. Tergum X with sclerotized and paired lateral and mesal lobes; lateral lobes each moderately long, wide basally, narrow apically, curved slightly upward in lateral view, apically simple, rounded, bearing multiple sensilla; mesal lobes elongate, digitate, curved slightly posterodorsad, pointed apically. Preanal appendages setose, rounded and wart-like. Phallic apparatus with sclerotized portion long, nearly cylindrical in lateral view (
Fig. 40
); in ventral view (
Fig. 41
) with broadly rounded phallobase; posterior part of phallotheca cylindrical; retracted phallotremal sclerite complex with small E-shaped process in ventral view; endotheca without microspines but with 2 long, almost-symmetrical and parallel subapical spines and 2 broad, asymmetrical, oval apical spines in ventral view.
