Setae numerous, regularly distributed on segments, 160(40) in V, 126(50) in VIII, 32+ 16 in XVIII, 60(20) in XIX, 62 in XXV, aa>ab, zz>zy. Male porophores superficial. Spermathecal pores 4 pairs, ventral in 5/6-8/9. Genital markings presetal, paired, one pair each on VIII and IX, two pairs on XVIII and XIX, and one pair on XVII, XX and XXI. Ampulla heart-shaped, divercula small, attaching to duct. Holandric. Testes sacs extending to the lateral line. The first seminal vesicles more developed and larger than the other seminal vesicles. Ovaries large on septum 12/13. Prostate glands in XVII-XIX. Intestine beginning at XV, without caeca. Typhlosole simple, lamelliform, T=0.35. Last hearts in XII. Septa 8/9/10 absent, 4/5–7/8 thickened. Pharyngeal micronephridia in 5/6/7/8. Lymph glands not developed (Data from Thai 1996: 4–5.).

Records from Vietnam. Quang Nam Province (Nui Thanh, Ky Ha).

Distribution. Only known from Vietnam.

Remarks. The species is fairly similar to Polypheretima monticola (Beddard, 1912) , but differs in the absence of septa 8/9/10, more complicated arrangement of genital markings in the male pore region. Types were rechecked for this study.
