Prószyński, J.: Salticidae (Araneae) from Mongolia

after a month of work usually, which somewhat influenced conditions of specimens. Some were also collected on the ground, stones, or sweeping on plants. As all of the collected samples contained numerous specimens of various insects and spiders, the exact living conditions of particular Salticidae species cannot be directly read from these labels. The amputated pedipalps are stored in microvials in the same tubes, the preparations of epigyne are permanently mounted in Canada balsam on microscopic slides. The study and their completion in, a relatively short time available, were possible owing to very kind and helpful attitude of DR. Z. KASZAB. I am also very grateful to DR. S. MAHUNKA of the Arachnological Laboratory and other staff members. I am indebted to colleagues from my research team in Siedlice and Wroclaw : D. E. M. ANDREEVA for allowing me to study her collection of Salticidae from Tadjikistan and Mrs. W. WESOÍOWSKA for consultation of identifications of Heliophanus species and to Mr. M. ZABKA for allowing me to study his unpublished drawings and redescription of the type of Phintella micans CAPORIACCO, 1935. A grant was provided by my employers — Wyzsza Szkola Rolniczo Pedagogiczna, Siedlce, Poland, for a five weeks research visit to the Hungarian Natural History Museum. Aelurillus festivus (C. L.

Nomenclatoral remark. — I consider it premature to lump together 80 species of Aelurillus and Phlegra as proposed by HARM 1977. Retaining Aelurillus for this species I had to change consequently its nearest relative, described originally as Phlegra potanini. I may add, however, that while the structure of the epigyne of a typical Aelurillus seems to be not related to Phlegra, the epigyne of Ae. festivus may be considered intermediate, with some homologies possible. The matter should be delayed until further study. Description of male The Mongolian specimen differs from the European ones (from the collection of the Hungarian Natural History Museum) by having intensely black clypeus and anterior surfaces of chelicerae, which are covered by dense fur of black setae. These contrast with pearl white eyes I and white setae on pedipalpal tibia and basally on cymbium. Eye field black with a dark deep bluish gleam like that in Ae. potanini. With sides of céphalothorax covered densely with black adpressed setae and a similar median thoracal streak, there remain two light dorso-lateral streaks on the thorax, covered with white setae. Abdom generally grey, covered with dark brown adpressed setae, sprinkled locally with white ones. These white setae concentrate in some areas making indistinct spots along median longitudinal streak: a pair of thin whitish lines ended by small swellings delimit anterior median dark brownish grey streak, extending over half of the abdomen. It is followed medially by a series of indistinct white marks forming a posterior light median streak. Anterior metatarsus and tarsus ventrally black, covered by dense black fur, dorsally fawn with a few minute whitisch scales. Legs yellow without any black markings ventrally on tibia I. Details of the diagnostic pedipalpal tibial apophyses are shown on figs 7,9. Female does not show any striking difference from European specimens. Epigyne is shown of fig. 1, its internal structure on fig. 3. The genus Aelurillushas a mainly South Palaearctic distribution, with Ae. festivus spreading North (actually reaching Arctic Circle in Eastern Siberia) and then from France in the West to North Korea and Japan. Also reported from Mongolia.
