( Figs 20–25 , 26–33 , 56–59 , 71–73 )

Clubiona genevensis L. Koch, 1866: 294 (deposition unknown; type locality unknown, but according to the species name, probably Geneva in Switzerland); Simon, 1932: 925, 930, 968, figs 1411, 1420 (♂♀); Wiehle, 1965: 478, f. 33-37 (♂♀); Helsdingen, 1979: 299, f. 4, 6-7 (♂♀); Mikhailov & Fet, 1986: 171.

Clubiona stigmatica Simon, 1878: 236 (♂♀); Simon 1932: 968 (Syn.).

Clubiona decora ; Bertkau 1890: 7; Bertkau 1893: 925; Kulczyński 1899; Lessert 1904: 388; Strand 1915: 159; Bacelar 1928: 179; Tyschenko 1971: 130, f. 310, 327 (♂ ♀) (all misidentifications).

Note. The name C. genevensis was first used by L. Koch in 1866, but only in an identification table, the most related species being C. comta . No further description was given, in contrast to many other Clubiona species described in the same paper and no figures were presented. As this description was unknown to Simon (1878) he named the same species Clubiona stigmatica . This species was later synonymised with C. genevensis by Simon (1932) and only since then the status of the species was cleared. A further confusion with C. decora is still continuing in recent catalogues (see under C. decora ).

Diagnosis. Clubiona genevensis and C. vegeta are sister species which are difficult to separate by the genital organs, especially the females. Males differ by the dark, strongly protruding chelicerae in C. vegeta ( Figs 43, 44 ), which are normally developed in C. genevensis ( Figs 20, 22, 23 ). Females of C. genevensis are separated by the copulatory openings being usually narrower, longer than wide ( Fig. 26 ) and the vulva with narrower copulatory ducts ( Figs 30, 32 ). In C. vegeta the epigyne has a wider atrium ( Figs 47–51 ). However, this character appears to be variable (see Figs 26–28 ) and thus not always reliable.

Description. Last described by Almquist (2006). Another relevant description is Helsdingen (1979).
