Infracapitulum and stylophore apunctate. Movable cheliceral digit with 3 teeth on distal tip, edentate on proximal end. Each medial and lateral branches of peritremes with weakly-marked borders between chambers.  Idiosoma. Propodonotal shield divided into 2 punctate lateral shields and apunctate posteromedial shield. Propodonotal setae weakly beaded, other idiosomal setae smooth. Setae sesituated anterior to c1. Setae f1short, f2medium-sized, setae h1and h2long. Setae f2situated distinctly anterior to f1. Opisthonotal lobes bearing setae f1, h1, h2, ps1and ps2. Genital setae hair-like, situated lateral to genito-anal opening and on level of setae ag3. Agenital and genital plates absent. Setae ag2situated posterolateral to setae ag1. Coxal fields I–IV well sclerotised, apunctate. Legs. Apodemes I subparallel to weakly divergent. Paraxial claws of legs I and II larger than antaxial claws, claws of legs III and IV equal in size. Measurements. Total body length 1000–1570. Length of stylophore 420.

Total body length 2,000 –2,600. MALE ( 6 specimensfrom typehost species).  Gnathosoma. Infracapitulum and stylophore apunctate. Movable cheliceral digit with 8–12 teeth on distal tip. Each medial branch of peritremes with 2 distinct chambers becoming rugosely sclerotised with indistinct near connection with lateral chambers, each lateral branch with distinct 13–16 chambers. Stylophore constricted posteriorly. Propodonotal shield entire, rectangular in shape, punctate near bases of setae vi, veand si, bearing all propodonotal setae except c2. Setae selocated anterior to c1. Hysteronotal shield divided into 2 lateral sclerites bearing bases of setae d2and large unpaired medial sclerite bearing bases of setae d1and e2. Medial hysteronotal shield and pygidial shield not fused but in very close proximity. Agenital plate absent. Coxal fields I–IV well sclerotised, apunctate.
