General description. Antennae, legs and wings in alcohol pale brown; length of each anterior wing of male 6.8– 7 mm (n=10), that of female 7.5– 8 mm (n=6).

Male genitalia ( Figs. 11–15 ): Segment IX with apicodorsal lobe ( Figs. 11, 12 ). Sclerotized bands articulating on segment X rather short ( Figs. 11, 12 ); in caudal view segment X with very narrow and long sclerotized tubercle in middle and posterior margins sinuate; apical edge angled dorsad ( Fig. 11 ) and edge with shape of large V in dorsal view ( Fig. 12 ). Coxopodite of each inferior appendage with oval basomesal tendon, this tendon with apical edge strongly sclerotized; dorsal edge of harpago slightly sinuous with basal half convex and apical half concave, ventral edge convex, tip rather thick and blunt. In lateral view phallic apparatus with dorsolateral processes of phallotheca very short and subtriangular, without posterior prolongations ( Fig. 14 ), in dorsal view narrow and parallel-sided ( Fig. 15 ); phallicata at mid-length with pair of dorsolateral lobes covered with small tubercles ( Figs. 14, 15 ); apical portion of phallicata with narrow sclerotized band J-shaped in lateral view ( Fig. 14 ) and U-shaped in dorsal view with tips curved laterad ( Fig. 15 ); end of paramere almost smooth, its crown bearing dense cluster of 40 long plumose spines ( Fig. 14 ).

Female genitalia ( Figs. 16–20 ): In lateral view, sclerotized part of segment VIII rather short, about 1.1 times as long ventrally as tall anteriorly, and posterolateral edges each slightly convex ( Fig. 16 ); in dorsal view, fully sclerotized and posterior edge straight ( Fig. 17 ); in ventral view, median lobe of posterior edge ~3 times as broad as long, evenly rounded ( Fig. 18 ). Anterior process of bursa copulatrix semicircular and its posteroventral edge bilobed in lateral view ( Fig. 19 ); posterior process gradually narrower toward tip in lateral view ( Fig. 19 ) and in ventral view parallel-sided for most of its length and nearly truncate at tip ( Fig. 20 ).

Remarks. Rhyacophila camiliensis sp. n. closely resembles R. zwickorum Malicky 1972 . The differences in the male genitalia are as follows: The dorsolateral processes of the phallotheca are very short and triangular and without posterior prolongations, in dorsal view parallel-sided; the basal tendon of each coxopodite lacks a hookshaped projection on the apicoventral corner and the apex of the paramere is almost straight. By contrast in R. zwickorum the dorsolateralal processes of the phallotheca are long and pointed at the tips of their posterior prolongations, in dorsal view they are broad at the bases and pointed at the tips; the basal tendon of each coxopodite has a hook-shaped projection on the apicoventral corner and the apex of the paramere is subtriangular and blunt. The female of R. camiliensis sp. n., shows the following differences: In R. camiliensis sp. n. the ventromesal lobe of segment VIII is narrower (~3 times as broad as long), but it is broader in R. zwickorum (~4 times as broad as long); the bursa copulatrix of R. camiliensis sp. n. is nearly semicircular and bilobed posteriorly, but it is oval and not bilobed in R. zwickorum ; in R. camiliensis sp. n. the posterior process is parallel-sided for most of its length and almost truncate at the tip in ventral view, but the posterior process is broad subdistally, abruptly becoming very narrow towards the tip in R. zwickorum .

Etymology. This species is named after the place near where the type specimens were collected.
