( Figs. 20–22 View FIGURES 20 – 22 , 40–41 View FIGURES 36 – 41 , 54–55 View FIGURES 52 – 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 m proximal to crossveins s and r-m; vein 2A not intersecting 3A.

Male genitalia ( Figs. 20–22 View FIGURES 20 – 22 , 40–41 View FIGURES 36 – 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 View FIGURES 36 – 41 ); in ventral view ( Fig. 41 View FIGURES 36 – 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.

Female: Not known.
