Zodarion bosmansi sp. n.

( Figs 9–12 , 17 )

Z. segurense: Pekár et al., 2003: 393–394 , fig. 15 (misidentification). Type data. Holotype male: Beja district: Parque Natural do Vale do Guadiana, Algodôr (UTM 29 SPB07 ), 16 July 2003, P. Cardoso leg.; paratypes: same locality, 27 August 2004, 2f, P. Cardoso leg. Type material deposited in SMF.

Material used for comparison. Zodarion segurense : male holotype, Spain, Jaén , Sierra de Segura, Segura, 25 May 1980, R. Jocqué leg. ( IRSNB) .

Remark. In our previous paper ( Pekár et al. 2003) we noted some dissimilarities between this species and a closely related Z. segurense Bosmans. As the type material of Z. segurense was not available, we could not designate a new species.

Diagnosis. This species is closely related to Z. segurense and Z. lusitanicum but it is markedly larger. Males of Z. bosmansi are further distinguished from these two species by shape of distal end of tibial apophysis, which is terminally truncate and by tip of embolus that is hooked. Females differ in shape of frontal margin of epigyne, which has paired sclerotised lips.

Description. Male: Total length 4.08 mm (SD = 0.31, n = 10), prosoma 2.03 mm (SD = 0.14, n = 10) long, 1.58 mm (SD = 0.14, n = 10) wide. Colour: Prosoma and chelicerae light brown, legs yellow. Sternum yellow with thin brown margin. Opisthosoma dorsally sepia brown, ventrally pale. Palp ( Figs 9–10 ): tibial apophysis long and gently curved, terminally truncate. Retinaculum (unnaturally expanded) with distal sharp tooth, embolus hooked, distal tegular apophysis broad and flattened.

Female. Total length 4.84 mm (SD = 0.45, n = 10), prosoma 2.33 mm (SD = 0.13, n = 10) long, 1.71 mm (SD = 0.15, n = 10) wide. Colour: as in males. Epigyne ( Figs 11–12 ): median plate wider than long, anterior margin well marked with paired sclerotised lips. Openings at lateral margins.

Material examined. Beja district: Parque Natural do Vale do Guadiana (all P. Cardoso leg., CPC): Algodôr (UTM 29 SPB07 ) , 30 July 2003, 1f; 13 August 2003, 1m+1f; 27 August 2003, 1m+ 1f; Ribeira de Limas (UTM 29 SPB28 ) , 16 July 2003, 1f; 30 July 2003, 8m+2f; 13 August 2003, 1f.

Distribution. Known only from southern Alentejo in Portugal ( Fig. 17 ).

Etymology. The name is a noun in genitive case, dedicated to Robert Bosmans, who made the extensive revision of this genus.
