Atropacarus (Hoplophorella) stilifer: Niedbała 2001

Diagnosis — Measurements of body of holotype 380 ( Hammer 1961). Measurements of paratype of Hoplophorella benoiti : prodorsum: length 180, width 126, height 78; notogaster: length 353, width 212, height 207.

Rather small-sized species; colour light brown, surface covered with small concavities. Prodorsum with median sigillar field narrow, longer than laterals; posterior furrows present, lateral carinae visible; sensilli long, recurved, sickle-shaped, inflated in distal end and covered with small spines; other setae slightly lanceolate; ss> in> ro> le; exobothridial setae vestigial. Notogaster with inflated setae, short (c 1 <c 1 -d 1) covered with spines in distal end, setae c 1 near the anterior margin, setae c 2 and c 3 remote from margin; vestigial setae f 1 posterior of h 1 setae. Ventral region; setae h of mentum almost equal as distance between them (shorter in specimen from Cameroon); formula of genital setae: 6: 3; between setae of anoadanal plates setae ad 2 lanceolate and longest; anal setae long, filiform, smooth, setae ad 3 shortest. Chaetome of legs incomplete; setae l’ on genua IV absent; setae d of femora I, curved and slightly remote from anterior margin.
