Diagnosis — Measurements of specimen from sample TAN-016. Prodorsum: length 465, width 328, height 151, setae: ss 96, in 271, le 25, ro 198, ex 6; notogaster: length 1000, width 707, height 687, c 1 238, c 1 /c 1 -d 1 =1.0, h 1 409, ps 1 368; genitoaggenital plate 273×182, anoadanal plate 333×192. Largesized species; colour brown; integument with deep concavities. Fields of prodorsum feeble, posterior furrow and lateral carinae absent; sensilli with rounded, ciliate head; interlamellar setae long, erect, obtuse distally, covered with small spines in distal half, similar to notogastral setae; lamellar and exobothridial setae minute; rostral setae erect or semi-erect, rough; in> ro> ss> le> ex. Notogaster with rather short (c 1 <c 1 - d 1) stout, setae covered with small spines in distal half; setae c 3 situated near anterior margin, setae c 1 remote and setae c 2 far from margin, vestigial setae f 1 anterior or posterior of h 1 setae. Ventral region; setae h of mentum longer than distance between them; formula of genital setae: 6(4+2): 3; adanal setae located near paraxial bor- der, setae ad 1 and ad 2 rough and longer than other setae. Chaetome of legs reduced, setae a’ on tarsi I absent; setae d remote from anterior border.

Remarks. Specimen from sample TAN-016 has some characters different from holotype: setae h 1 and ps 1 are longer than the other setae; the distance between setae ps 3 and ps 4 considerably longer than that between ps 2 - ps 3; vestigial setae f 1 slightly anteriorly of setae h 1; setae ad 1 similar to notogastral setae, they are covered with small cilia, obtuse; the remaining setae of anoadanal plates spiniform.

Localities in Tanzania: the Uluguru Mts.

Distribution — Afrotropical, central and eastern part and eastern islands.
