HARIS ATTILA: New Nematinae species from Mongolia (Hymenoptera: Tenthredinidae)

NEW NEMATINAE SPECIES FROM MONGOLIA (HYMENOPTERA: TENTHREDINIDAE) pies and vertex, shiny. Mesonotal lobes with moderately deep and moderately dense punctures, moderately shiny. Mesoscutellum, mesoscutellar appendage and metascutellum with deep, moderately dense punctures, slightly shiny. Mesopleuron, mesosternum, metasternum, metapleuron and katepimeron smooth and shiny. Abdominal tergites 1-3 with fine coriaceous sculpture, moderately shiny. This sculpture gradually disappear from other tergites, these tergites more or less smooth and shiny, last tergite smooth and shiny. Last abdominal tergite with narrow and rounded apical projection. Hind tibial spur short. Length of inner hind tibial spur : apical width of hind tibia: 7:11. Hind tibial spurs equal in length. Penis valve in Fig. 3. Length: 5.9 mm. The new species runs to Amauronematus viduatus (Zetterstedt, 1838) in Zhelochovtsev's key (ZHELOCHOVTSEV 1988). Differences: the new species extensively yellow especially on abdominal sternites. Furthermore, apical projection of penis valve long, significantly longer (Fig. 3) than that of A. viduatus (Zetterstedt, 1838) but much shorter than that of the abnormis-cornutus group. The new species is also resembles in colour to Amauronematus leucolenus (Brischke, 1883), however the strikingly different penis valves clearly differentiate the 2 species. Recently Liston described a new species, namely A. spaethi Liston, 2005 from Corsica and placed it into the viduatus group (LISTON 2005). The male of A. spaethi is unknown.
