Diagnosis – Male palp with a short tibial apophysis, wide at base. Embolus short, with a membraneous basal part. Male
holotype
:
Holotype
pale, probably due to many years in ethanol. Carapace brownish, ocular area yellowish. The hairy appearance characteristic for the type species of the genus,
Alfenus calamistratus
, is not observable, moreover there is no hairs on the carapace. Chelicera with two smaller prolateral and one larger retrolateral teeth. Abdomen oval, covered with hairs, with brownish arrow-shaped pattern on a whitish background. Legs almost equal in length, the forelegs brownish, hind legs yellowish with darker stripes.
Measurements – Male: total length 6.9. Carapace 3.25 long, 2.25 wide, 1.63 high at PLE. AEW 2.3, PEW 2.0, OCA 1.6 long. Abdomen 3.25 long, 1.65 wide.
Palp – With simple structure (
Figs 3
E-F). Tibia with short apophysis. Bulbus weakly sclerotized (in contrast to
A. calamistratus
), sperm ducts visible. Embolus short, with a membranous basal part. The palp of this species is so different from
A. calamistratus
that we are in doubt about the generic placement (
Figs 2D, F, H
). However, we have currently no suggestiuon for alternative placement of this species.
Female: unknown.
Distribution –
Cameroon
/
Equatorial Guinea
(see discussion under genus).
