description: Dolophilodes morsei sp. nov.
(Figs. 13–16)
Holotype 3: INDIA: Arunachal Pradesh: Lumla, 2,300 m, 15-v-2011, Pandher, deposited in PUPM.
Paratype: Data same as holotype, 1Ƥ, deposited in PUPM.
Diagnosis. This species is allied to D. torrentis Kimmins 1955, D. punjpullaensis sp. nov., D.malickyi sp. nov., and D. elongata Kimmins 1955 in the presence of a ventral process on segment VIII. However, the shape of the inferior appendages and the presence of a long, median spine along with a pair of small unequal spines set D. morsei sp. nov. apart from allied species. This species especially resembles D. torrentis reported from Myanmar in the shapes of segment IX and the inferior appendages in lateral view and in the dense pilosity of the inner basal part of the inferior appendages. However, in D. morsei the basal segment of each inferior appendage is narrow basally and broad apically, its ventral margin is more concave, its apical segment is broadest basally, its dorsal and ventral margins are constricted preapically and convex dorsally in lateral view; the lobes of segment X have their mesal margins somewhat dilated mesally and apically; the phallus has a long median spine with a basal plate and this spine is longer than the basal plate in both lateral and dorsal views, 2 small unequal spines are also present posterior to basal plate, a small fork-like structure also is present anterior to basal plate. In contrast, in D. torrentis the basal segment of each inferior appendage is with only a slight median constriction ventrally, the apical segment is slightly constricted near its base in lateral view; the lobes of segment X have smooth mesal margins; the phallus has a single semicircular median spine and no small spines visible.
Description. Adult male: Color in alcohol dark brown, antennae brownish, almost equal to length of forewings, head infuscated with mixture of golden and black setae, thorax brownish black, maxillary and labial palpi pale brown. Body covered with inconspicuous, sparse and yellowish brown pubescence. Length of each forewing 7.76 mm; each forewing with forks I–V present; fork I petiole almost 2.5X as long as fork; discoidal cell well developed; median cell about 2X as long as discoidal cell; hindwings each with forks I–III and V present; 3 anal veins extending freely to wing margin.
Male genitalia (Figs. 13–16). Sternite VII without ventral process. Sternite VIII with well developed ventral process. Segment IX sclerotized, posterodorsally reduced, anterolaterally convex, dorsal aspect oblique, posterolaterally with deep concavity near base to accommodate inferior appendages. Inferior appendages each 2-segmented, elongate, basal segment almost 1.5X as long as apical one, dorsal and ventral margins sinuous, narrow basally and broadest apically; apical segment broad basally, dorsal margin convex while ventral one concave, constricted preapically, somewhat bulbous apically and internally with spinules. Segment X almost triangular, 2-lobed, apices of lobes with rounded margins and meeting dorsomedially, nearly equal to preanal appendages in dorsal view, projecting downward and rounded apically in lateral view. Preanal appendages each elbow-shaped, with incurved basal margin, setose in lateral view, finger-like in dorsal view and divergent. Phallus large, membranous, with lateral prominence in lateral view, having following spines: Long median spine with basal plate and this spine longer than basal plate in lateral as well as dorsal views, 2 small unequal spines also visible in lateral view posterior to basal plate, small fork-like structure also present anterior to basal plate.
Distribution. India: Arunachal Pradesh.
Etymology. This species is named in honor of Dr. J.C. Morse a renowned contributor to Trichoptera systematics.
