Arctosa lacustris (Simon, 1876) ( Figs 13-16 )

Lycosa subhirsuta L. Koch, 1882 : 653, pl. 21, figs 28-29 (descr. male, female); new synonymy.

Alopecosa subhirsutella Roewer, 1955 : 221 (replacement name); new synonymy.

Lycosa subhirsuta ; Roewer, 1960: 874 (transferred back, without arguments).

Type material

Lectotype male and paralectotype female of Lycosa subhirsuta from Spain, Baleares, Soller valley, mid-April and Miramar, May, Schaufuss leg. ( ZMB 7911 ); examined .

Comparative material examined

SPAIN. Caceres: Plasencia (N 40°1’52’’ E 6°5’18”), 525m, 1 male 1 female, IV.1990, P. Poot leg. ( CRB) .

Comments

The holotype male has only one palp left with a tegular apophysis as in Arctosa lacustris . The female has an intact epigyne with a broad median septum, as clearly shown in Koch’s figure 29 ( 1882), corresponding well with the epigyne of A. lacustris (compare Figs 13, 15 with Figs 14, 16 (taken from KNÜLLE 1959). Lycosa subhirsuta and its replacement name Alopecosa subhirsutella thus become junior synonyms of Arctosa lacustris .

Distribution

Mediterranean, Canary Islands.
