Harpagophora diplocrada: Attems 1909 a: 42 , figs 90, 91; 1922: 42; 1928: 374; Schubart 1966: 168; Demange

Diagnosis: Lateral lamella of telocoxite with large median digitiform process directed distally, and with one to three small teeth below this ( Fig. 64). First femoral process ( Fig. 63, fp1) small, partially curved around the base of the larger spine and concealed in gonocoel. Second femoral process ( Fig. 63, fp2) originating at knee, distally divided into 2 spines. Pectinophore ribbon-like ( Fig. 64, pe), and incurved towards spine branch, Spine branch narrow and apically acute ( Fig. 64, sb).

Description:

Size: Mid-body width in males 9 mm, in females 11 mm. Male with 48 segments, female with 49.

Colour: Frons chestnut brown, head darker. Antenna chestnut brown, 6 th antennomere darker. Collum dark brown; prozonites yellowish, dark yellow longitudinal stripes present at height of ozopores; metazonites dark brown to black, anteriorly lightly bordered; ozopores darker. Limbus yellowish. Last segment dark, only median ridge on paraprocts lighter. Sternites yellow, legs dark brown.

Head: Frons finely wrinkled, with 5 supralabral pits. Epicranial suture distinct, interocular suture only faint. Suture from hind corner of eye visible, eye relatively close to antenna.Antennomere 2>3>4>5>1>6>7, and antenna hardly reaching posterior border of collum.

Collum: Lateral margin wide, thickened, 1 or 2 folds at anterior and lateral borders.

Tergites and sternites: Ozopores from 6 th segment onwards. Prozonites longitudinally striated, ventrally turning into horizontal ridges of metazonites; metazonites with longitudinal striation, ending below ozopores. Prozonites and metazonites divided by a distinct suture. Limbus finely dentate. Sigilla ovoid.

Legs: Pads becoming smaller posteriorly, on last segments only distal pad present, this always being larger than interior pad.

Gonopods: As in diagnosis.

Material examined: NAMIBIA: 1♂ 1♀ Keetmanshoop district, Noachabeb 91 [27°26'00"S 18°31'15"E, 1477 m], 7–12.i.1972 ( SMN 21671 ) ( NMNW) ; 1♂ Windhoek , Nauchas 14 [23°39'02"S 16°17'42"E, 1764m], 27–30.iii.1995, E. Marais ( SMN 22130 ) ( NMNW) .

Distribution: Namibia, widely distributed north of Windhoek. Redman et al. (2003) provided the following additional localities: Otjimbingwe [22°21'01"S 16°07'59"E, 898 m], Keetmanshoop [26°34'28"S 18°07'58"E, 1004 m], Narldas Sil [co-ordinates uncertain], Naukluft Mountains [24°07'S 16°10'E, 1585 m], Grootberg area [more than one site by this name], Halsos Mountains [co-ordinates uncertain] and Daan Viljoen Nature Reserve [22°32'18"S 16°56'38"E, 1669 m].

Remarks: The whereabouts of the type material is unknown.
