Telmatoscopus Eaton, 1904: 58. Type species: Pericoma advena Eaton, 1893, by subsequent designation of Quate (1965) = Sciria Enderlein, 1935: 247. Type species: Pericoma advena Eaton, 1893, by original designation.
Diagnosis. Frons and clypeus clearly separate, not protruding over eye margin; flagellomeres asymmetrically nodiform, with paired, curved, leaf-shaped to digitiform ascoids; flagellomere 13 with elongate neck, flagellomere 14 with elongate apiculus; R 2 + 3 not connected to R 4; apex of R 5 ending in apex of wing; basiphallus narrow in dorsal view and distally ending in two short branches with membranous connection to distiphallus; distiphallus composed of paired, symmetrical phallomeres; aedeagal complex encapsuled in parameral sheath, parameral sclerites separate, usually slightly curved in dorsal and ventral views, usually narrow, arranged transversely near bases of phallomeres; surstylus with indistinctly fringed tenacula; epandrium with single aperture.

Discussion. The definition of the advena group as distinct from other Telmatoscopus auct. was first pointed out by Vaillant (1989), and followed upon by Ježek & Mogi (1995). Due to the latter authors' incorrect assertion that Pericoma morula is available for type species designation in Telmatoscopus, however, they used the name Sciria Enderlein, 1935 for the advena group. Some authors, e.g. Salmela (2005) and Svensson (2009) followed this arrangement; however, since Pericoma advena is the type species of both Telmatoscopus and Sciria, the latter name falls as an objective junior synonym. For the taxa similar to Pericoma morula, the name Seoda Enderlein, 1935 is available (type species Pericoma labeculosa, see below).
