Shilenkov, V. G.: Some notes on South Siberian Trechini (Coleoptera, Carabidae) with descriptions of three new species

8 (9) Fore tibiae pubescent on external face. Recurrent striae free. Hind angles of pronotum obtuse, but extreme tip feebly prominent as small tooth. Altai Altaiotrechus alticola IABL. — KHNZ. 9 (8) Fore tibiae glabrous on external face. Recurrent stria joining stria 5. Hind angles of pronotum obtuse with rounded apex. 10 (11) Apical hook of aedeagus long and strongly curved dorsally (fig. 11). East Sajan Mts. Trechus almonius REITT. 11 (10) Apical hook of aedeagus short and feebly curved dorsally (fig. 12). Mongolia, Changai Mts (fig. 4) Trechus hangaicus sp. n. 12 (7) Eyes larger, more protrudent, longer than temporae. Aedeagus without apical hook. Fore tibiae with groove, or at least with its trace near apex on external face. 13 (14) Aedeagus (fig. 13) massive, thickened at apex, inner sac with two spines and groups of small teeth. Pronotum narrow, with obtuse hind angles. Uniformly pale-brown. Tannu-Ola Mts. (fig. 6) Trechus korotyaevi sp. n. 14 (13) Aedeagus (figs 8-10) smaller, with well developed copulatory piece and tufts of long teeth. Body colour darker. 15 (16) Pitchy-brown. Pronotum narrower, 1.32-1.37 times as wide as long, hind angles prominent as short acute teeth. Aedeagus (fig. 10) with slightly thickened tip, copulatory piece as long bar. West Sajan Mts. (fig. 7) Trechus mordkovitschi sp. n. 16 (15) Dark-brown. Pronotum wider, 1.40-1.47 times as wide as long, hind angles obtuse, no prominent. Aedeagus (figs. 8-9) with simple tip, inner sac armed two discoid plates and long bar, bifurcate at apex (fig. 5) Trechus montanus MÖTSCH. Epaphius (Epaphius) secalis (PAYKULL, 1790) Carabus Secalis PAYKULL, 1790: Monogr. Carab. Suec. : 94 (type locality: Sweden). Trechus laticollis MOTSCHULSKY, 1844: 235 (type locality: village Turka on the shore of Baikal). For other synonyms and bibliography, see JEANNEL, 1927: 132, 1941: 317; CSIKI, 1928: 245; LINDROTH, 1945: 666; BURAKOWSKI & al., 1973: 179; PAWLOWSKI, 1975: 30. Distribution. A widely distributed Euro-Siberian species restricted in the East by Lena river and Transbaikal region. Ecology. Inhabits several types of birch forests, sometimes in lowland forests and gardens, rare in open country with grass cover, near water. Material. Novosibirsk distr. : environs of Barabinsk, village Karachi (MN, ISU). Irkutsk distr.: Irkutsk (ISU, ZIL); Bolshaja Glubokaja (Shelekhov env.) (ISU); Troitzk (Zalari env.) (ISU); Vydrino (ISU), Kultuk (ZIL) (Sljudjanka env.); Elantzy (ISU), Kosaja Stepp (ZIL) (Olkhon env.); Belaja river (ZIL). Burjatskaja ASSR: Iljinka (ISU). Taxomical remark. Lectotype, rf of Trechus laticollis MÖTSCH. (ZMM), designated here, bears two labels: "L. Baikal" and "Trechus laticollis mihi, Turkinsk". This specimen is, however, in fact, an Epaphius secalis (PAYK.) with slightly monstrous pronotum. Synonymy was ascertained for the first time by JEANNEL (1927: 132). Epaphius (Epaphiolus) rivularis (GYLLENHAL, 1810) Bembidium rivulare GYLLENHAL, 1810, Ins. Suec, II: 33 (type locality : Sweden: Kinnekulle). Trechus nigricomis MOTSCHULSKY, 1844: 235, tab. X, fig. 5-5', syn. n. (type locality: Kiachta). For other synonyms, distribution and ecology, see JEANNEL, 1927: 138; CSIKI, 1928: 244; LINDROTH, 1945: 661; BURAKOWSKI & all, 1973: 197; PAWLOWSKI, 1975: 27. Distribution. Until recently it had been known only from Europe, where it is widely distributed in the North and very sporadically in the mountains of Central Europe. In fact it possesses a Euro-Siberian area of distribution. It was found in South Baikal region (SHILENKOV, 1979: 41), and now I have specimens from other parts of Siberia.
