Material. INDIA, state Karnataka: Udupi district, river Seethanadhi-hole near Seethanadhi, 30.I.2013, N. Kluge, L. Sheyko: 3 larvae; boundary of Shimoga and Uttara Kanada districts, river Sirawati near Mavigundi, Jogg Falls, 4.XII. 2008. coll. M. Chertoprud: 4 larvae.
Discussion. Larva is adequately described by Sivaramakrishnan & Peters (1984). The following characters can be added. Mouth apparatus of « Dilatognathus - type », with highly modified labrum, mandibles, hypopharynx, maxillae and labium (Kluge 2012). Apex of maxilla lacks apical flange, dentiseta and subapical row of pectinate setae [which are present in most other Atalophlebomaxillata (Kluge 2012)]; instead of them, medio-apical angle of maxilla is produced to a long sclerotized apical tusk (Sivaramakrishnan & Peters 1984: Fig. 15). Maxillary palp specialized as filtering, with 1 st segment shortened and thickened, with strengthened muscles—both flexor and extensor of 2 nd segment; 2 nd segment with a compact group of 4–6 long arched pointed stout seta near apex on lateral side (Figs 46, 47; Sivaramakrishnan & Peters 1984: Fig. 15) (instead of one straight seta in N. ganeshi sp.n. — Fig. 7); 3 rd segment with only one kind of setae—very long stout pointed setae directed apically and forming nearly regular rows (Figs 46–49). Labial palp has lost setae on 1 st and 2 nd segments and bears long pointed setae on 3 rd segment. Outer side of 3 rd segment with very long setae, which in proximal part of the segment form regular transverse rows; dorsal side also with long setae; between long setae of outer side and long setae of dorsal side, smaller setae are situated (Figs 50, 51). Thorax wide; fore protoptera brought together (Fig. 44). Fore tibia, beside dense pointed bipectinate stout setae on inner side and non-pectinate very stout setae on ventral (posterior) side [see Iscini (2)] (Fig. 52p) bears numerous very long slender pointed setae on dorsal (anterior) side (Fig. 53a); unlike N. ganeshi sp.n., dorsal side has no longitudinal row of stout elongate blunt setae [see Notophlebia (3)]. Dorsal (anterior) side of middle and hind tibia with a longitudinal row of stout elongate blunt setae (Fig. 54a) (as in N. ganeshi sp.n.). Claw with 2–4 denticles on proximal portion, 8 denticles in anterior row and 1 larger denticle apically-posteriorly. Posterior margins of abdominal terga with a regular row of pointed denticles alternated with enlarged setae (Fig. 39); denticles become longer from tergum I to tergum IX, on posterior segments much larger than in N. ganeshi sp.n. Posterior margins of abdominal sterna without denticles. Tergalii with proximal-anal convexity, which is poorly expressed on tergalius I, gradually larger from tergalius I to tergalius VI and wellexpressed on small tergalius VI (Figs 40–43). Male larval protopenes long, with gonopore on dorsal side and with gonoduct lined by cuticle (Fig. 45).
