Diagnosis of female.

The female of this species has an epigyne somewhat similar to that in Icius minimus but has the spermathecae placed parallel to the posterior edge of the epigyne, while in I. minimus they lie obliquely (compare Fig. 14 B View Figure 14 with fig. 81 in Wesołowska and Tomasiewicz 2008). These species also differ in carapace colour: in I. minimus , white hairs create a cross pattern in the eye field (fig. 78 in Wesołowska and Tomasiewicz 2008), while I. pulchellus has a dark eye field (Fig. 13 D – G View Figure 13 ).

Description.

Male: See Haddad and Wesołowska (2011). General appearance of living male as in Fig. 12 A, D View Figure 12 , in alcohol as in Fig. 13 A, B View Figure 13 ; palpal organ as in Fig. 13 C View Figure 13 .

Female: Measurements: Cephalothorax length 2.0–2.4, width 1.4–1.7, height 0.8–0.9. Abdomen length 2.3–2.7, width 1.6–1.9. Eye field length 0.8–0.9, anterior width 1.1–1.2, posterior width 1.3–1.4. General appearance of living female as in Fig. 12 B, E View Figure 12 , in alcohol as in Fig. 13 D – G View Figure 13 . Carapace brown, with lighter median streak on thoracic part, lateral sides dark yellow, eye field black. Dense light grey hairs on carapace, amongst them long brown bristles, more numerous on eye field. Chelicerae unidentati, light brown. Sternum, labium and endites yellow. Abdomen ovoid, yellow, with leaf-shaped brownish pattern (Fig. 13 D, E View Figure 13 ). In some specimens, abdomen light, creamy-yellow (Fig. 13 F View Figure 13 ), sometimes with brownish marks (Fig. 13 G View Figure 13 ). Venter covered with silver spots (translucent guanine). Spinnerets light. Legs yellow, their hairs faint, spines long, brown. Epigyne short and wide (Figs 13 H View Figure 13 , 14 A View Figure 14 ). Copulatory openings large, widely separated. Internal structure simple (Fig. 14 B View Figure 14 ), seminal ducts tubuliform, spermathecae elongated, accessory glands present.

Distribution.

Species previously known only from the Free State Province, recorded from the Northern Cape for the first time based on this material ( Dippenaar-Schoeman et al. 2023).

Remark.

The female of this species is described here for the first time.
