Elytra 1.8 x longer than wide; surface with erect, yellowish brown, dense, elongate setae; punctures coarse. Apical margin of last abdominal ventrite with two well developed incisions in male ( Fig. 5 View FIGURE 5 G); weakly and medially depressed in females ( Fig. 5 View FIGURE 5 H). Penis ( Figs 5 View FIGURE 5 C–5D) slender, gradually narrowed towards apex; apex of dorsal surface with deep medial notch; apex of ventral surface widely rounded; almost straight in lateral view, apex with extremely narrow notch between dorsal and ventral surfaces; ventral surface smooth. Internal sac without dense setae; median endophallic spiculae elongate, about 0.7 x as long as penis, inner margin straight, covered with minute spines, basally conjoined; one short endophallic spiculum between median endophallic spiculae, basally covered with setae, apically tapering, ventrally curved in lateral view; two pairs of dorsal endophallic spiculae elongate, basally conjoined, apex rounded, one pair a slightly shorter than the other; 11 pair of lateral endophallic spiculae that are horn-like and small, located from near base to on-half length; one ringlike spiculum anteriorly connected with first horn-like lateral endophallic spiculae, anteriorly open. Gonocoxae ( Fig. 5 View FIGURE 5 E) elongate, 8.8 x longer than wide, sides narrowed in apical one-third; apices narrowly rounded; apex with nine setae; slender from midpoint to base but abruptly widened at base. Ventrite VIII ( Fig. 5 View FIGURE 5 F) well sclerotized; spiculum long; apex square, apical margin truncate, with several short setae at sides; disc with several elongate setae at sides. Receptacle of spermatheca ( Fig. 5 View FIGURE 5 I) wide, narrowly separated from pump; pump strongly curved and apically tapering; proximal spermathecal duct short, connected with receptacle.
