Diagnosis — Measurements of holotype: prodorsum: length 338, width 222, height 121; notogaster: length 636, width 424, height 444.

Medium-sized species; colour brown; cuticle finely punctate. Prodorsum with two pairs of long, rigid lateral carinae; sensilli long, baciliform, smooth, and only covered with small spines at top; other setae (except minute exobothridial) rather short, similar in length, erect; lamellar and rostral rough, interlamellar fine, smooth; in -in> le -le> ro - ro. Notogaster with setae relatively short (c 1 <c 1 - d 1), setae c 1-3 remote from anterior margin, setae c 1 more than setae c 2 and c 3. Ventral region; setae h of mentum considerably shorter than distance between them; 9 pairs of genital setae, 4 of them on progenital position; 2 pairs of aggenital setae, ag 2> ag 1; anal setae an 1 and an 2 smooth, attenuate longer than other rough setae of anoadanal plates. Chaetome of legs (without tarsi): I: 1-3-5(2)-5(1), II: 1-4-3(1)-5(1), III: 2-2-2(1)-2(1), IV: 2-1-1(1)-2(1); all tarsi heterotridactylous.
