Head: Head capsule length, 1.33–1.36 mm; width, 1.16–1.19 mm. Dorsum of head dark-brown except around eyes and posterior one-fifth yellowish (Fig. 40). Dorsal and lateral portions of head covered with long, black, truncate peg setae, with tapered setae in anterior three-fourths (Fig. 54). Frontoclypeus lacking same setae except for anterolateral corners. Frontoclypeus with anterior margin slightly concave, posterior half with darker muscle scars; lateral margins wider at mid-length (Fig. 40). Head ventrally brownish, with stridulatory lines in anterior half; posterolaterally paler with group of muscle scars (Fig. 41). Labrum golden-brown; elliptical in dorsal view; bearing well-developed, lateral, golden-brown brushes and dorsal short setae; with pair of long anteromesal setae; posteromedially slightly convex (Fig. 42). Mandibles dark- brown, each with 2 apical and 3 mesal teeth, left mandible with well-developed setal brush; lateral surfaces of both mandibles with scattered setae (Fig. 43). Submentum brown; lacking anteromesal cleft; anterior margin concave; anterior margin and lateral areas with short and long setae (Fig. 44). Anterior ventral apotome broadly triangular; posterior ventral apotome small, triangular (Figs. 41, 44).
Thorax: Pronotum dark-brown, muscle scars paler (Fig. 46); densely covered with long, truncate peg setae and tapered setae; anterior margin bearing same setae (Fig. 55). Meso- and metanota brown, muscle scars concolorous; each with crescentic black mark posteromesally, lateral margins black; mesonotum with small black band on each side near posteromesal crescentic black mark; each covered with long, dense scale hairs and long, inclined truncate peg setae; anterior margins bearing same setae (Figs. 47–48, 56–57). Prosternite brown; narrow transverse; broad dark band along posterior margin; with pair of large, paler sclerites posterolaterally (Fig. 45). Foretrochantin deeply forked, with dorsal branch slightly longer than ventral branch; ventral branch with spike-like setae (Fig. 49). Forelegs stouter than other legs; posteromesal surfaces of coxae and trochanters densely covered with feather-like setae and stout setae; each femur with long and spike-like setae in anterior surface and ventral margin; tibia and tarsus each with rows of short, stout setae (Fig. 49). Mid- and hind legs similar in size, shape, and structure; each with dense spike-like setae and stout setae on mesal surface of coxa through tarsi; with row of feather-like setae on ventral margin (Figs. 50–51). Mesosternum with one pair of gills and metasternum with 2 pairs of gills; gills consisting of central stem bearing many lateral filaments.
Abdomen: Abdominal segments densely covered with dark, club-like hairs (Fig. 58). First sternum with 2 pairs of gills with adjacent bases. Segments II–VI each with 2 pairs of lateral and one pair of median gills (Fig. 59). Sternum VIII with pair of large, subtriangular sclerites bearing spike-like setae. Sternum IX with pair of large, triangular sclerites bearing spike-like setae emanating from prominent sockets (Fig. 52). 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. 53).
