Diagnosis. Body with 21 leg-bearing segments. Spiracles oval-shaped ( Fig.17C View FIGURE 17 ). Antennae with 19–21 antennomeres including first two and 1/3 of the third glabrous ( Fig. 16 View FIGURE 16 ). Coxosternal plate with 6(7)+6(7) teeth ( Fig. 16D View FIGURE 16 ). Paramedian grooves distinct on tergites 3–20, but absent on sternites ( Fig. 17A View FIGURE 17 ). Coxopleural process long, conical, with 3 apical spines ( Fig. 12A View FIGURE 12 ). Spines on prefemur of the ultimate legs large and arranged in rows ( Figs 17D View FIGURE 17 , 18B View FIGURE 18 ).

Previous records in Vietnam. HOA BINH (Mai Chau District); HA NOI (Ba Vi NP); HAI PHONG (Cat Ba NP); HA TINH (Vu Quang NP); KHANH HOA (Nha Trang); GIA LAI (An Khe District, Buon Luoi); DA NANG; LAM DONG (Da Lat); DONG NAI (Cat Tien NP; Ma Da); TAY NINH (Lo Go—Xa Mat NP); BA RIA—VUNG TAU (Hang Bai Khang Island) ( Schileyko 1992, 1995, 2007; Attems 1938).

Distribution. The species has also been reported from Indonesia and Papua New Guinea ( Lewis 2001; Schileyko 2007).

Remarks. The species seems to be distributed widely in Vietnam ( Fig. 19 View FIGURE 19 ). We have not observed considerable variation among examined specimens. Thus, we considered two subspecies O. multidens multidens and O. multidens nordicus as only one species O. multidens .
