 Type species. Attus semi-glabratus Simon, 1868 [= " Euophrys" semiglabrata (Simon, 1868) = Iberattus semiglabratus (Simon, 1868) comb. n.].   
 Etymology. Name created by combination of letters Iber [-ian Peninsula]- attus, derived from Iberian. Peninsula and the synonymic genus name Attus, commonly used in the past for these spiders. Remarks. Premises for the present delimitation of a new genus were documented by Hęciak & Prószyński (1984), who proved that palp, epigyne and internal structure of epigyne of Attus semi-glabratus does not agree with both Phlegra Simon, 1876 and Euophrys C. L. Koch, 1834 (see facsimiles of descriptions by Simon – Fig, 8) they have also noted analogy of the multi-chambered spermatheca to that structure in Habrocestum Simon, 1876 (Fig. 2R - which, however, does not belong to EUPHRYINES). With these considerations, species semiglabrata was left provisionally ("provision" lasting 34 years, as it turned out) in the genus Euophrys, pending more research. There are obvious resemblances in spermathecae with " Saitis " imitatus (Figs 2 B-C, M-N), but interpretation of these requires better documentation of the latter species.   
 Diagnosis. Euophrys like spider (Figs 1 A-D), recognizable by internal structure of epigyne. (Figs 1Q, S-T) reflected in part also in external appearance of epigyne - Figs 1F, P, R), strikingly different from Euophrys and closely related genera (compare Figs 2 O-Q).. Palp (Figs 1E, G-I) is obviously EUPHRYINES like, but pointing out generic characters on it require further comparative research. Change of dorsal color pattern after preservation in alcohol is as profound as in Euophrys, so may take place also as rapidly (Prószynski et al, 2018 c: 44).   
 Description. General appearance and palps have some similarities to Euophrys (see facsimiles of the original descriptions - Fig. 5, below), but multichambered spermatheca excludes closer proximity. Looking at epigyne alone, possible placement is indicated by anterior position and proportions of translucent chambers of spermathecae, in front of epigynal "windows" (Figs 1 P-T), the detailed documentation of internal structures of epigyne (Figs 1 Q, S-T) suggests relationship with little known multichambered genera discovered in tropical areas.   
 Distribution. I. semiglabrata has been reported from a few localities in Portugal, Spain, France, the issue of conspecificity of these specimens was not discussed, but there may be more species, misidentified or not yet discovered. The scarcity of information on several genera is presumably due to poor exploration of arachnofauna of Mediterranean, more relevant species could be possibly found in southern Mediterrranean countries of Africa and Near East (Prószyński, 2003).
