Lazarov, Stoyan, 2009, Harpactea konradi, a new spider species from Bulgaria, (Araneae, Dysderidae), Zootaxa 2140, pp. 33-37 : 34-37

Harpactea konradi sp. n. ( Figs 2–7 )

Material examined: Bulgaria: Eastern Rhodopes, Haskovo District, near Mineralni Bani Village, next to Aida Hut, Garvanets Hill, 750 m, 4 December 1998, 1 male holotype, 1 female paratype (leg. Delyan Delchev) ( Fig. 1 ). Depository: The holotype and the paratype are kept in the collection of the Institute of Zoology, Sofia.

Etymology: Named in memory of well known araneologist Konrad Thaler.

Diagnosis: Resembles Harpactea srednagora Dimitrov & Lazarov, 1999 in having the bifurcate embolus but this is thicker and more massive, and the conductor is tighter and longer in H. konradi sp. n. ( Figs 2–4 ). Females are very similar to those of other Harpactea species, but there are differences in details of the epigyne ( Figs 5–7 ).

Description: Male: Total length 6.4; cephalothorax length 3.1, width 2.4; abdomen length 3.3. Carapace red-brown, chelicerae red-brown with 2 rows of 2 teeth, eyes 6, arranged in circle, typical for genus, sternum red-orange, abdomen whitish, legs red-orange.

Leg spines: Coxae I, II without spines, III 3 dorsal, IV 4–7 dorsal. Femora I 4 prolateral, II 4 prolateral, III 8 pairs dorsal, IV 10 dorsal. Patellae I, II without spines, III–IV 1 dorsal. Tibiae I, II without spines, III–IV 4 whirls of spines. Spines on metatarsi as on tibiae. Tarsi without spines.

Palp ( Figs 2–4 ). Bulbus globular, conductor lamellate, embolus apical bifurcate, massive. Proximal branch of embolus straight, pointed, distal branch curved, extending beyond conductor.

Female: Total length 7.1; cephalothorax length 2.5, width 1.7; abdomen length 4.6. Carapace and chelicerae red-brown, sternum red-orange, abdomen whitish, legs red-orange. Vulva cosisisting of an anterior basal arch, a sclerotized reverse T-shaped receptacle (anterior spermatheca) and a posterior diverticulum ( Figs 5–7 ).

Distribution and habitat. The new species has been found in Southern Bulgaria, inhabiting screes and dry stony areas covered with bushes at an altitude of about 750 m.
