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 sikkimensis sp. nov. ( Figs. 14–16 , 38–39 , 48–49 ) Diagnosis : The male genitalia of this species resemble those of Chimarra rama Malicky & Chantaramongkol 1993b , C. devva Malicky & Chantaramongkol 1993b , C. shiva Malicky & Chantaramongkol 1993b , C. atara Malicky & Chantaramongkol 1993b , and C. momma Malicky & Chantaramongkol 1993b , all reported from Thailand . In all these species, segment IX is anteroventrally produced in lateral view. Furthermore, C . sikkimensis is similar to C. rama in the form of the lateral lobes of tergum X in lateral view but differs distinctively in the shape of the inferior appendages (broad and quadrate apically in C. sikkimensis sp. nov. but narrow and pointed apically in C. rama ) and the mesal lobe of tergum X, which is pin-head-like at its apex in C. sikkimensis , but curved posteriorly in C . rama . The phallic apparatus of C. sikkimensis is with two sickle-shaped apical endothecal spines in ventral view and 4 asymmetrical spines in lateral view, whereas two asymmetrical endothecal spines are visible in C. rama . Description : Length of each male forewing 5.25 mm (n=4), female forewing 7.50 mm (n=6). Color in alcohol, uniformly fulvous and covered with inconspicuous, sparse fulvous pubescence. Each antenna 3.25 mm long (n=10); maxillary palps each 1.13 mm long (n=10), segment 3 slightly longer than 2, 5 shorter than 3; labial palps 0.62 mm long (n=10). Forewing venation: Stem of Rs curved, slightly sclerotized and thickened at inflection; fork at base of discoidal cell not thickened, length of discoidal cell about 2 times width; crossvein m proximal to crossveins s and r-m ; vein 2A not intersecting 3A ( Figs. 48, 49 ). Male genitalia ( Figs. 14–16 , 38–39 ): Tergum IX very short, forming extremely narrow transverse band dorsally; anterolateral margins concave and anteroventral margins in lateral view distinctly produced anterad; posterior margin sinuous; posteroventral process weakly keel-like. Inferior appendages each obliquely directed upward, stout, narrow proximally and wider distally, with truncate apex slightly concave in lateral view and with apicodorsal and apicoventral corners spine-like and curved mesad. Tergum X with sclerotized and paired lateral and mesal lobes; in lateral view basal half of each lateral lobe broad and with conspicuous dorsal bulge, distal half tapering to blunt apex; each mesal lobe digitate and capitate, apically rounded like pin head in lateral view. Each preanal appendage knob-like in dorsal view. Sclerotized portion of phallic apparatus long, slender in lateral view ( Fig. 38 ), phallobase broad, cylindrical; posterior part of phallotheca cylindrical, somewhat expanded in ventral view ( Fig. 39 ); phallotremal sclerite complex not observed; endotheca with 5 microspines inside retracted phallotheca in ventral view, 2 long, slender, sickle-shaped spines present inside endotheca near apex of phallotheca and 2 asymmetrical, intermediate-size, anteroventrally directed spines visible inside endotheca near microspines in ventral view.
