HAMS A.: SAWFLIES FROM SAKHALIN AND THE KURIL ISLANDS 195 nal segments: 4 : 3 : 17 : 12 : 12 : 8 : 8 : 9 : 9. Clypeus truncate. Frontal area flat, without pentagonal area. Head without hind postoccipital carina. Hind ocelli very close to the hind margin of the head. Their distance about 2/3x as long as the diameter of an ocellus. Eyes large, genae linear. Temples short, head contracted behind the eyes. Head densely, roughly punctured, hardly shiny. Pronotum minutely and densely punctured, moderately shiny. Mesopleuron with irregular coriaceous surface sculpture. Moderately shiny. Mesonotum with moderately dense coriaceous sculpture, shiny. Mesoscutellum nearly smooth and shiny, only with few deep wrinkles. Mesoscutellar appendage large. Length of mesoscutellum (longitudinally): length of mesoscutellar appendage = 4:3. Mesoscutellar appendage moderately shiny, with dense microsculpture and with a longitudinal raising keel. Postscutellum with fine microsculpture, blunt. Penis valve in Fig. 4. Claws simple, without inner tooth and basal lobe. Length: 4.5 mm. Holotype: male: Anivskij, Novo-Aleksandrovsk, 11. 08. 1973. The new species belongs to the melanocarpa group. Their typical character is the large dorsal hook in the male genitalia. The new species has uniqe position in the group having very special penis valve (Fig. 4) and large mesoscutellar appendage. Amauronematus pseudoleptocephalus spec. nov. Male. Head light yellowish brown with a large dorsal spot which covers the total frontal area, vertex and laterally reaches the eyes. The head beyond temples and vertex where is connected to the prothorax is also black. The other parts of the head: most of the temples, outer orbits, upper hind corners of eyes, face below antennae and mouthparts remain light yellowish brown. Scape and pedicel entirely black. Antennái flagellar segments black above and reddish ochraceous below. Thorax black, hind margin and corner of pronotum and tegulae yellowish white. Legs yellowish. Basal 2/3 of fore femora, basal 1/3 of the middle femora black. Basal 1/4 of hind femora brownish black. Hind tibiae with longitudinal black line. Hind tarsi black. Wings hyaline. Venation brown. Costa and stima light brown. Abdomen black above. Last abdominal sternite reddish yellow. The next 2 apical sternites brownish black but reddish yellow in the middle. The other sternites brownish black with reddish yellow hind margines. Body elongated. Antennae long, about as long as the whole body. Ratios of the antennái segments: 5 : 3 : 24 : 28 : 30 : 24 : 23 : 19 : 21. Head strongly contracted behind the eyes. Frontal area pentagonal, sunken and strongly limited by margines. Head without postoccipital carina on temples and vertex. Clypeus very slightly emarginated only in the middle of its front margin, nearly subturncate. Head densely, moderately deeply and moderately roughly punctured, moderately shiny. Pronotum finely granulated, moderately shiny. Mesonotum, mesoscutellum and mesoscutellar appendage shallowly, densely and finely punctured, shiny. Mesopleuron shiny with very fine and shallow coriaceous sculpture. Subapical teeth of claws hardly shorter than apical. Abdominal tergites shiny. All tergites (including propodeum) with very fine surface sculpture. Last apical tergite with rectangular projection (Fig. 6). Penis valve with long, straight hind margin (Fig. 5). Length: 5.7 mm. Length of fore wing: 5.6 mm. Holotype: male: Sakhalin, Anivskij, Novo-Alexandrovsk, 16. 07. 1973. The new species is closely related to Amauronemtaus leptocephalus (THOMSON 1862). The straight hind margin of the penis valve clearly differs the 2 species. The body: head, thorax, abdomen except last sternite of the male Amauronematus leptocephalus is black.
