Afrodacarellus Hurlbutt View in CoL (30 described species)

Movable and fixed cheliceral digits with 2–5 and 4–6 teeth, respectively. Cheliceral arthrodial process shaped like a cylindrical brush. Epistome with an anteromedian extension of about uniform width along its entire length, or narrower or wider at the base; usually flanked by one or more pairs of anterolateral extensions longer, subequal or shorter than the anteromedian extension [with anterior region subtriangular in A. euungulae (Karg) ]. Seta h 3 about in longitudinal line with h 1 and posterior and mediad to h 2. Idiosoma elongate or suboval, 200–600 µm long and 90–330 µm wide at widest level. Ratios of width of podonotal and opisthonotal shields to maximum width of idiosoma 0.9–1 and 0.9–1.1, respectively. Dorsal idiosomal setae smooth. Podonotal shield 0.9–1.2 times longer than wide; usually smooth, sometimes ornamented; with or without punctate band along posterior margin; with 21– 23 pairs of setae, including two pairs (j 1 and z 1) near anterior margin; without transverse suture between setae j 4 and j 5 and with four scleronoduli between setae j 5 and j 6. Soft integument along lateral margins of podonotal shield with 0–2 pairs of setae. Opisthonotal shield 0.9–1.3 times longer than wide; usually ornamented, sometimes smooth; with or without punctate band along anterior margin; with 18–20 pairs of setae. Soft integument along lateral margins of opisthonotal shield with 0–3 pairs of setae. Peritreme extending anteriorly to level between anterior margin of coxa III and the middle of coxa II. Peritrematic shield fused anteriorly to or free from podonotal shield. Presternal platelets absent. Sternal shield longer than wide, with anterior margin indistinct and posterior margin usually concave, sometimes straight or with a central spine-like projection. Genital shield usually longer than or sometimes subequal to posterior width; posterior margin straight. Opisthogaster without platelets between genital and ventrianal shields. Ventrianal shield longer or as long as wide, usually ornamented, with 5–7 pairs of preanal setae; anterior margin usually straight, sometimes slightly concave or slightly convex. Soft integument around ventrianal shield with 0–2 pairs of setae. Usually with a pair of rounded (usually with a pore-like structure) and a pair of elongate metapodal platelets; sometimes only with a pair of rounded or elongate platelets. Pretarsus I present. Seta pl 4 of tarsus IV absent (present in A. camaxiloensis ).
