(Figs. 19–38)
Larva: Total length 17.0–17.5 mm (n=10). Overall body shape typical for Hydropsychidae.
Head: Head capsule length, 1.53–1.62 mm; width, 1.36–1.45 mm. Dorsum of head brownish, with yellow ring around each eye (Fig. 16). Dorsal and lateral portions of head covered with long, black, truncate peg setae, with tapered setae in anterior three-fourths (Fig. 33). Entire frontoclypeus covered with same setae; frontoclypeus with anterior margin strongly convex (Fig. 20). Ventral surface of head brownish, with stridulatory lines in anterior half; posterolaterally paler with group of muscle scars (Fig. 21). Labrum brown; rounded in dorsal view; bearing welldeveloped, lateral, golden-yellow, pectinate setae and dorsal long, stout, dark setae, with one pair of longer, dark anteromesal setae (Fig. 22). Mandibles dark-brown to black with 2 apical and 3 mesal teeth, left mandible with well-developed setal brush; outer surfaces of both mandibles with scattered setae (Fig. 23). Submentum darkbrown; lacking anteromesal cleft; anterior margin concave; anterior margin and lateral area with short and long, dark setae (Fig. 24). Anterior ventral apotome broadly triangular; posterior ventral apotome small, triangular (Figs. 21, 24).
Thorax: Nota brownish, covered with same setae as on dorsum of head (Figs. 26–28, 34). Pronotum with weak posterior sulcus. Prosternite brown; broadly transverse; dark band along posterior margin; with pair of large, paler sclerites posterolaterally (Fig. 25). Foretrochantin forked; dorsal branch as long as ventral branch, with stout setae on ventral branch (Fig. 29). Forelegs stouter than other legs, each with femur widened; posteromesal surface of coxa, trochanter, and femur densely covered with feather-like setae; femur with long and spike-like setae in anterior surface and ventral margin; tibia and tarsus each with rows of short, stout setae (Figs. 29, 35–36). Mid- and hind legs similar in size, shape, and structure; with dense spike-like setae and stout setae on mesal surfaces of coxae through tarsi; each with row of feather-like setae on ventral margin (Figs. 30–31). Mesosternum with one pair of gills; metasternum with 2 pairs of gills; gills consisting of central stem bearing many lateral filaments.
Abdomen: Abdominal segments with dense dark, club-like hairs of various shapes (Fig. 37). First sternum with 2 pairs of gills with adjacent bases. Segments II–VI each with 2 pairs of lateral gills and 1 pair of median gills (Fig. 38). Sternum VIII with pair of small, subtriangular sclerites bearing spike-like setae. Sternum IX with pair of large, triangular sclerites bearing spike-like setae emanating from prominent sockets (Fig. 32). Tergum IX with pair of small lateral and dorsolateral sclerites. Anal prolegs each with bent claw and cluster of long bristles, spike-like setae present on dorsal surface (Fig. 19).
