Description
Propsilocerus jacuticus (Zvereva)
(Figs. 35–39)
Syndiamesa jacutica Zvereva, 1950: 273; Pankratova 1970: 73; Ashe & Cranston 1990: 236 (as nomen dubium, probably
Tokunagayusurika). Tokunagayusurika jacutica (Zvereva): Meriläinen 1987: 90. Propsilocerus jacuticus (Zvereva); Saether 1997: 242; Makarchenko & Makarchenko 2006: 349, 519, 661; Kiknadze et al. 2007:
36 (karyotype); Ashe & O’Connor 2012: 501.
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.
