| Summary: | Fannia altaica Pont & Vikhrev, 2009 Figs 2 A–C This species was described from a single male from the Kosh-Agach district (Lake Zerlyukol’-Nur, 2300–2400m, 49º56'N, 88º20'E). The authors pointed out that treeless mountain tundra was a most unusual habitat for Fanniidae and that F. altaica might be associated with burrows of Marmota species (Pont & Vikhrev 2009). This does indeed appear to be the case according to the new material reported here, as several males and one female have been collected at the entrance to burrows of the Altai Marmot. Material examined. 4 males and 1 female, RUSSIA, Respublika Altai, Kosh-Agachskiy rayon, verkhov’ya r. Naryn-Gol [upper River Naryn-Gol], 2520 m, 49º49'N 89º32'E, na surchinakh [from Marmot burrows], 15– 19.vii.2009, V. Sorokina (2 males OUMNH & BMNH, rest SZNM); 4 males, the same, V. Sorokina, T. Novgorodova (SZNM); 1 male, Respublika Altai, Kosh-Agachskiy rayon, dolina r. Tara [River Tara valley], 2300 m, 49º39'N 88º13'E, na surchinakh [from Marmot burrows], 11.vii.2009, V. Sorokina, T. Novgorodova (SZNM). The series of males enables us to add some taxonomic details to the original description: parafacial without setulae in 6 males from Naryn-Gol, with setulae in 2 males from Naryn-Gol and the male from River Tara valley. Prealar usually with a short setula behind it or in front of it. Basal quarter of fore and mid tibiae reddish-yellow and hind tibia wholly reddish-yellow, or all tibiae wholly yellowish. Hind femur with the pv setae less than twice as long as femoral depth. Hind tibia with the ad seta slightly basad or slightly apicad of the submedian d seta, and usually with 2 av . Sternite 1 densely setulose. Abdomen (ventral view) and terminalia as in Figs 2 A–C. Description. Female: The female has not previously been described. It differs from the male as follows: Head : Frons broad, at middle half of head width at this point. Fronto-orbital plate and parafacial yellowishgrey dusted. Frontal vitta at narrowest point slightly broader than a fronto-orbital ... |
