Berinda amabilis Roewer, 1928 View in CoL (p. 106, Figs 11–13 View FIGURES 9 – 12 View FIGURES 13 – 16 ), CRETE: Chania: Akrotiri, Governeto monastery (type locality, not reexamined).

Talanites aculeatus Charitonov, 1946 : p. 26, fig. 43, UZBEKISTAN: Yakkabagh (type locality, not examined).

Diagnosis: The species resembles B. aegilia . Males are easily recognized by the fingerlike retrolateral apophysis of the patella (unique within Berinda ) and the slender retrolateral apophysis of the tibia of the pedipalp ( Fig. 4 View FIGURES 1 – 4 ). A distinct conductor ( Fig. 3 View FIGURES 1 – 4 ) ending as an S-shaped sclerotized band (possibly the posterior hook in other Berinda species, like B. ensigera ) is also a distinctive character of males. Females are recognized by the anterior lateral margins widely curved at sides, and the small (compared to B. aegilia ) conical hood at midline ( Fig. 7 View FIGURES 5 – 8 ). Spermathecae are globular with lateral introductory ducts ( Fig. 8 View FIGURES 5 – 8 ).

Description: See Chatzaki et al. (2002a) (re-description).

Diagnosis: Males can be recognized by the tibial apophysis which is straight and very long, almost as long as the cymbium ( Fig. 9 View FIGURES 9 – 12 ). The conductor is strongly developed, with three elements: a membranous anterior sac

1. This species is listed in Platnick’s catalogue (2009) as Berinda ensiger . However because Berinda is a female noun, we persist in our proposition of changing the corresponding adjective to “ ensigera ” ( Chatzaki et al. 2002a).

(a), a sickle-shaped guiding structure (b) leading to a sclerotized posterior hook (c) ( Figs 9–10 View FIGURES 9 – 12 ). All three elements are interconnected. This configuration is shared among three species: B. ensigera , B. cypria and B. hakani (see below) and is almost indistinguishable. In females there is a scape (Sc) ( Fig. 11 View FIGURES 9 – 12 ) with an anterior hood as in Gnaphosa . Lateral margins are parallel and open at posterior part, leading to the copulatory orifices.

Comments: Both sexes of B. ensigera share very similar structures with B. cypria and B. hakani . However males are easily distinguished by the tibial apophysis, distinct in all three species (compare Figs 10 View FIGURES 9 – 12 , 14, 16 View FIGURES 13 – 16 ). In females the distinction is more difficult: the shape of the lateral margins is one distinctive character (compare Figs 11 View FIGURES 9 – 12 , 20, 22 View FIGURES 20 – 23 ) and the length and shape of the scape is another. However the latter may differ among individuals depending on the extension of the organ at the moment of the animal’s death.

The new synonymy here proposed is based on the description of a female as Haplodrassus grazianoi by Caporiacco (1948: 59, Fig. 10 View FIGURES 9 – 12 ). The illustration presented by Caporiacco clearly represents one of the three Berinda species ( B. ensigera , B. cypria or B. hakani -see below and Figs 11–12 View FIGURES 9 – 12 and 20–23 View FIGURES 20 – 23 ). The shape of the scape mostly resembles B. ensigera , although the shadows at the lateral margins (also in combination to the shape of the scape) would suggest B. hakani . However since B. ensigera was found by the authors multiple times on the island of Rodos, which is the type locality of H. grazianoi , it may be safely concluded that the latter corresponds to B. ensigera .
