( Figs 9–19 , 52–55 , 68–70 ; Map 1)

Clubiona diniensis Simon, 1878: 238 (holotype ♂ from France, Alpes de Haute Provence, vallée de la Bléone, MNHNP, not examined); Simon 1932: 924, 929, 967, figs 1408, 1418 (♂, ♀); Urones 1985: 47; Barrientos et al. 2016: 97 (♂). Clubiona baborensis Denis, 1937: 1050 (two ♀♀ syntypes from Algeria, Wilaya de Setif, Zouagha forest, 9 and 15.V.1936, probably in MNHNP, not examined). N. Syn.

Note. Clubiona baborensis was described from Algeria by Denis (1937) and only the female is known. We captured several females, corresponding completely with Denis’ excellent figure of the epigyne, together with males. Both are identical to C. diniensis Simon, 1878 and C. baborensis Denis, 1937 therefore becomes its junior synonym.

Diagnosis. Males of C. diniensis can be recognized by the long palpal tibia (nearly twice as long as wide) ( Fig. 11 ) and by the embolus originating anteriorly ( Figs 12 , 17 ). In the other species of the genevensis group, the palpal tibia is much shorter and the embolus originates in basal or median part of the bulbus. Females are distinguished from the other species of the genevensis group by the presence of two distinct oval atria in the epigyne ( Figs 13 , 18 ).

Ecology. In the Maghreb, C. diniensis lives in all types of forests from the seaside up to 800m. Adult males were collected from December to May, adult females from February to June.

Distribution. Clubiona diniensis appears to be a common species in Algeria but rare in Morocco and Tunisia. It was originally described from France, Alpes-de-Haute Provence ( Simon 1878) and also cited from the French departments Aude, Var and Pyrénées-Orientales, from Catalunya in Spain ( Simon 1932) and from Coimbra in Portugal ( Bertkau 1893). Later, it was rarely collected. Soyer (1963) found it in the Bouches-du-Rhône, France, Caporiacco (1949) in Romagna, Italy, Urones (1985) and Barrientos et al. (2016) in Spain and Cardoso et al. (2008a, b) in Portugal.
