Type material
Holotype female of I. holosericeus, Spain, presumably lost, not examined. Neotype female of I. holosericeus, Spain (BMNH 19.9.18.5696-97) Seidlitz leg., herein designated. Syntypes [5 males (m), 1 female (f) and 1 juvenile (j)] of I. triangulifer from Sicily, Italy (NMW 117), Grolnnann leg., examined; Syntypes (1m and 1f) of I. andalusicus from Andalusia, Spain (MNHN AR4603), examined; Holotype juvenile female of I. algericus (NRS 18) from Bona, Algeria, examined; Holotype female of I. tripolitanus (MZUF) from Homs, Libia, examined.
NOTES. (1) Bacelar (1932) had already suggested I. valentinus as senior synonym of I. holosericeus, I. andalusiacus and I. triangulifer, but did not formally propose this synonymy. Vol (1999a) agreed with Bacelar’s suggestion that all Spanish species are the same (I. valentinus, I. holosericeus, I. andalusiacus). However, neither Bacelar (1932) nor Vol (1999a) formalized the synonymy properly. Therefore, Platnick’s catalogue (2013) has not incorporated this synonymy and they are all herein treated as new synonymies. (2) The species I. holosericeus was described by Koch, and the description was posteriorly formalized by Ausserer (1871). The holotype was not found at the British Museum or at the Naturhistorisches Museum Wien, two collections that house much of the material described by Ausserer. Other German museums have been visited and the holotype of I. holosericeus was not found. Smith (1990) was also not able to find the type and considered it lost. (3) The types of the following species were not found at MNHN: I. fuscostriatus Simon 1885; I. maroccanus (Simon 1873); I. mogadorensis Simon 1909; I. numidus Simon 1909. As described below, extensive material was examined from several localities, including the type localities mentioned above and only I. valentinus, which seems to be a widespread species, was found. (4) Vol (1999b) provided new distribution data for I. valentinus, which are listed below: Istan, slopes of the lake La Conceptión, Málaga, Spain; near Puerto de Pescadores, Málaga, Spain. Additionally, Cardoso and Morano (2010) stated that the species I. valentinus occurs in Spain in the provinces of Málaga, Murcia, Sevilla and Valencia.

Diagnosis
Representatives of this species differ from congeners by the labium twice as wide as long with few cuspules (fewer than 15) (Figure 3A). Female representatives can be distinguished by the spermathecae receptacula as wide as long with several apical lobes (Figure 3D). Male representatives can be distinguished by the curved embolus of the palpal bulb (Figure 3B, C).
