Abdomen dark grey. Genitalia of both male and female as in Figs. 41-45. Taxonomic remarks. In describing his D. subrostratus , O. Pickard-Cambridge (1873) noted a pronounced similarity of his new form with the European D. picinus (Blackwall, 1841), but gave the differences in the shape of both male carapace and palpal tibia. An examination of several series of both D. picinus and D. subrostratus has led me to the conclusion that these distinguishing characters referred to by O. PICKARD-CAMBRIDGE (1873) do not per­mit a safe discrimination of the males of the two species concerned. The only reliable dif­ference lies in the shape of the embolic division. On the contrary, the females are easily dis­tinguishable by the much less separated lateral plates of the epigyne of D. picinus (cp. WIEH­LE 1960 and Fig. 46). The synonymy of D. subrostratus and D. cuneatus is doubtless. The situation with D. maculifrons is more obscure. The holotype female of the latter taxon claimed to have been deposited in the collection of the Institute of Zoology of the Academy of Science of Poland, Warsaw, is presumed to be lost (A. SLOJEWSKA, pers. comm. of 10.XII. 1986). However, the original illustration of KULCZYNSKI (1926) seems to be sufficient, in my opinion, for a confirmation of the above synonymy. Distribution. This species has been recorded in southern Cisbaikalia (PICKARD-CAM­BRIDGE 1873), Yamal and Yenisey (ESKOV 1986)*'; in North America - New Hampshire, New York, Quebec, Ontario and Newfoundland (CROSBY et BISHOP 1933; HACKMAN 1954). In Siberia this species is distributed from Yamal eastward up to Kamchatka, and from Tai­myr southward up to Sayan Mts. Diplocephalus uliginosus sp. n.
