Trebacosa brunhesi Villepoux, 2007: 1  , figs 1, 2A –F, 3 (male holotype from FRANCE: Réserve naturelle du marais de Lavours (commune de Cézeyrieux, dép. de l'Ain, France N 45° 49' E 5° 45'), 20/6/1986, O. Villepoux leg., MNHN-AR 14431, examined. Female allotype from the same locality, 16/6/1995, MNHN-AR 14431). – New synonymy

Diagnosis. Males of Trebacosa  europaea  can be differentiated from those of T. marxi  by the elongated median apophysis ( Figs 23–24View FIGURES 23 – 24), which is 1.7 times longer than wide. Females can be distinguished by the lower atrium (which is even smaller than those of T. marxi  ) and the HS and VC subequal in diameter ( Figs 8–19View FIGURES 8 – 18View FIGURES 19 – 22). In T. marxi  , the VC is roughly twice as high as the HS, while VC is only 1.3–1.5 higher, than HS in T. europaea  .

Intraspecific variation. We examined T. europaea  and T. brunhesi  specimens from Hungary and France, respectively and they showed the same shape and ratio in the median apophysis ( Figs 25–26View FIGURES 25 – 28), being about 1.7 times longer than wide. We also got a bleached out specimen from Belarus ( Fig. 27View FIGURES 25 – 28), and specimens with expanded palps from Greece ( Fig. 28View FIGURES 25 – 28). Despite the suboptimal condition of these specimens and palps, the characteristic median apophysis together with the terminal apophysis and the central tegular process is identical both in shape and in its length/width ratio ( Figs 27–28View FIGURES 25 – 28).

The original description of Trebacosa europaea  was based on 16 males. Kancsal et al. (2010) reported 22 further Trebacosa europaea  specimens from Lake Velencei, Hungary (without mentioning any females, although three were caught), while Buchholz & Schröder (2013) and Schröder et al (2011) reported seven (3 males, 4 females) T. europaea  specimens from the Aladjagiola wetlands in Greece, but also without any further details. Villepoux has collected hundreds of Trebacosa  specimens in France, listed here. Based on the specimens no significant differences have been observed, hence the synonymy seems justified.
