Seven new species of the genus Chimarra Stephens (Trichoptera: Philopotamidae) from India Author Pandher, Manpreet Singh Author Saini, Malkiat Singh text Zootaxa 2012 3478 313 329 journal article 10.5281/zenodo.212378 808e1e15-5bcd-4acb-ac95-2b64f28db085 1175-5326 212378 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 . FIGURES 1–9. Chimarra spp. nov., male genitalia. 1–3, C. rongliensis sp. nov. : 1, left lateral view; 2, dorsal view; 3, ventral view of right inferior appendage. 4–6, C. soloi sp. nov. : 4, left lateral view; 5, dorsal view; 6, ventral view of right inferior appendage. 7–9, C. mawsmaiensis sp. nov. : 7, left lateral view; 8, dorsal view; 9, ventral view of right inferior appendage. 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.
