Material examined. Russia: 1 adult male, West Siberia, Tomsk Region, Chernoe Lake of Chulma River basin ( Ob River basin), 12.VII.1979, leg. A. Ruzanova.

Comments. Of all the species of the genus Propsilocerus , P. jacuticus has been extremely insufficiently studied. There is only one description of an adult male from Finland ( Saether 1997), while the type locality of the species is in west of the Ural Mountains in the Vichegda River, Komi, Russia. In our material, there was only one male P. jacuticus in poor condition from western Siberia, but we found it expedient to give a description of his structures that were preserved in the slide.

Description

Adult male. Total length 9.3 mm. Total length/wing length 1.85. Temporal setae including 7 inner verticals and 8 outer verticals. AR 2.34. Clypeus with ca 40 setae. Acrostichals absent, dorsocentrals 28; prealars 13–14, supraalar 1; preepisternum with 18–20 setae. Scutellum with ca 40 setae. Wing length 5.1 mm. Anal lobe moderately projecting. R with 16 setae; other veins bare. Squama with ca 64 setae. LR 1 0.65, BV 1 2.40, SV 1 2.56.

Hypopygium ( Figs. 35–39 View FIGURES 35–39 ). Anal point, 88 μm long, slightly tapering to blunt apex, with 18–20 setae, 36–40 μm long; tergite IX with 100–110 setae, 40–44 μm long; laterosternite IX with 14–16 setae. Phallapodeme 138 μm long; transverse sternapodeme 144 μm long. Gonocoxite 771–787 μm long; superior volsella as in Fig. 39 View FIGURES 35–39 ; median volsella as tubercle with 1–2 setae. Gonostylus bilobate, outer branch 525–541 μm long, with 4 megasetae, 15–20 μm long; inner branch 394–410 μm long. HR 1.46–1.47.

Pupa and larva were described by Zvereva (1950), Pankratova (1970) and Saether (1997).

Distribution. Palaearctic species, known from Finland, North of European part of Russia and West Siberia.
