Papp, L.: New species and records of Sphaeroceridae (Diptera) from the USSR

The new species differs from its related species only by its male and female genital structures. Male pregenital tergite with a pair of very long, lateral marginal bristles (about 0.36 mm long), 5th sternite V-shaped, emarginate mediocaudally. Anterior hypopygial, process (Fig. 13) with a very long and thin apical part (apex rounded), and with very wide base; hind hypopygial process perpendicular to the sagittal plane, short, apex truncate and much broader, than base (apex 2/3 as wide as length of hind hypopygial process); pregonite (Fig. 14) extreme with very wide apical part, sloped cranial apex and very wide base; postgonite thin with 3 proclinate short thin hairs. Female 7th abdominal sternite rounded, 8th sternite four times wider than long (!), quadrangular, with straight apical margin, the two sclerites detached from 8th sternite comparatively broad (Fig. 9), subanal plate with some thick apical bristles; 8 th tergite in 2 pairs of separated sclerites, ventral sclerites long and thin, dorsal sclerites with some marginal bristles, similar to those of the subanal plate. Supra-anal plate slightly convex dorsally with pointed caudal apex and with a pair of thin hairs. Wing length of holotype male: 2.20 mm, paratypes: 1.97-2.61 mm; width of wing of holotype male: 0.89 mm, paratypes: 0.77-1.14 mm. Body length: holotype male: 2.29 mm, paratypes: 2.063.20 mm. Holotype male: Habarovsk krai, P. Osipenko, ELBERG, 20. 7. [19] 73 — "tarnanüt". — Paratypes: 4 çf, 1 9 : data same as for holotype; 3 9 '• ibid., "Carex niit"; other paratypes: Habarovsk krai, leg. ELBERG: 2 çf : Magadan obi., Gorbinski, 13. 8. 72, "jögi Salix"; 1 çf, 1 9 '• Pivan, 16. 8. 73, "ojokallas"; 3 çf, 3 9 : Habarovsk, 24. 8. 73 ; 1 9 : Bolon, 23. 8. 73, "joekallas". The holotype and the paratypes are in the Zooloogia ja Botanika Instituut, Tartu, except for five paratypes which are deposited in the Hungarian Natural History Museum, Budapest. The new species L. (R.) praeapicalis sp. n. can be separated from the other East Palaearctic species of the lutosa species-group (paralutosa, spinisterna, spinicaudata, sajanica) by the extremely long apical part of its male anterior hypopygial process and its extremely wide pregonite; the female 8th sternite is straight apically as in sajanica, but 8th sternite of praeapicalis sp. n. is very short (1/4 of its width), ventral sclerite pair of the 8th tergite separated from dorsal sclerite pair and they are much narrower than in its congeners.
