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 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).
