description: Chimarra mawsmaiensis sp. nov.
(Figs. 7–9, 32–34, 44–45)
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 m 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.
