Diagnosis.

Haplodrassus isaevi is most similar to Haplodrassus dalmatensis but differs by the shape of the terminal apophysis, which has only one tooth-like process (two tooth-like apical processes in Haplodrassus dalmatensis ), in lacking a tooth on the embolus (embolic tooth present in Haplodrassus dalmatensis ), and also by the proportions of the epigyne. Differences also occur in the spination of certain leg segments: male metatarsus I with two ventral spines in Haplodrassus isaevi , but without spines in Haplodrassus dalmatensis ; female metatarsus IV with 4-5 retrolateral spines in Haplodrassus isaevi , but with 3 spines in Haplodrassus dalmatensis .

Description.

Males (n =5) and females (n = 5). Measurements (♂ / ♀): total length 5.4-7.2 (6.4) / 5.5-7.4 (6.3); carapace 2.3-2.9 (2.7) / 2.4-3.0 (2.7) long, 1.9-2.4 (2.2) / 1.9-2.2 (2.0) wide; abdomen 3.1-4.3 (3.7) / 3.0-4.4 (3.7) long, 1.7-2.3 (2.0) / 1.8-2.8 (2.3) wide.

Length of leg segments:

Length of palp segments (male / female): femur 1.0-1.2 (1.1) / 0.8-1.1 (1.0), patella 0.4-0.5 (0.4) / 0.4-0.5 (0.5), tibia 0.3-0.4 (0.3) / 0.3-0.4 (0.4), tarsus 1.0-1.2 (1.0) / 0.6-0.7 (0.7).

Chelicerae with 2-3 promarginal and 2 retromarginal teeth in males and females. Number of promarginal teeth varies from 3 (most common) to 2 (seldom). One female studied had one chelicera with 3 and the other chelicera with 2 promarginal teeth. Coloration grey.

Male palp as in Figs 25-27. Terminal apophysis sharply turned, without ridge, but with tooth (Tt) in subterminal part, embolus without tooth.

Epigyne as in Figs 30-31. Fovea long, lateral pockets slightly converging, foveal width less that spermathecal span.

Distribution.

Greece, Ukraine (Crimea), Russia (Rostov Area), Kazakhstan (West-Kazakhstan Area) ( Ponomarev and Tsvetkov 2006; Piterkina and Ovtsharenko 2007; Platnick 2012; present data).

Habitats.

Steppes.

Phenology.

In Crimea ♂♀ - X-XII, ♀♀ - II-III, V, the peak activity of adults occurs in December.

Comments.

In Crimea we found both closely related species, Haplodrassus dalmatensis and Haplodrassus isaevi , to be syntopical in two localities (Sudak Distr., 10 km W Sudak, Mezhdurechie Vill. and Feodosiya Distr., Karadag Nature Reserve). However, these species have quite different phenologies and adults of the two different sp ecies do not co-occur. The reproductive period of Haplodrassus dalmatensis is in May-July with the peak in June, and in Haplodrassus isaevi adults can be found in October-December, with their peak of activity in December.
