Roháček, J. ; Papp, L.: A review of the genus Paralimosina L. Papp (Diptera, Sphaeroceridae), with descriptions of ten new species

M-shaped, velvety black, dull mark. Frontal lunule ochreous brown, yellowish microtomentose ; face dark brown, gena partly reddish brown, occiput blackish brown. Cephalic chaetotaxy: pvt minute and hair-like; 2 usual ors; 3 ifr, anterior thin and short, middle and posterior moderately long; g well developed. Eyes not much reduced, their diameter about twice as long as smallest genal height. Antennae dark brown, 1st flagellomere with dense and long cilia; arista three times as long as antenna, with short cilia. Thorax dark brown, with brownish grey microtomentum. Two dc, the posterior long, the anterior less than twice as long as dc microsetae; 8 rows of ac microsetae. Scutellum comparatively long, its length 0.7 of its width. Apical sc long and arising on small tubercles; lateral se as long as scutellum length. Two stpl, but the anterior only slightly longer than the several additional setulae on sternopleuron. Legs largely dark brown but knees, apices of tibiae and all tarsi reddish brown. f

2 chaetotaxy as in Figs 111, 112, with a row of short ventral spines terminated by reduced va. The ratio t

2 : mt

2 = 1.65. Wing pale brownish, C brown, other veins very pale brown. R2 +3 and R4 +5 sinuate, the latter proximally curved, distally straightened. Coloured extension of Ml +2 beyond tp very short but with a long colourless fold; brown process of Mi +4 much longer. Wing measurements: length 2.23 mm, width 1.00 mm, C-index = 1.12, ta-tp : tp = 1.88. Haltères yellow. Abdomen blackish brown, rather shining, despite greyish brown microtomentum. S5 (Fig. 2) simple, with sinuate posterior margin and short dense setae. S6 (Fig. 1) with 2 tooth-like processes on its stripe-like ventral part. Genitalia — Periandrium (Figs 3, 4) long, ball-shaped, uniformly setose. Subanal plate reduced and fused with periandrium, carrying a very long caudal bristle and very weak fine paired ventral setae. Gonostylus (Fig. 6) — posterior lobe more slender and with long hair-like setae and some micropubescence ; anterior lobe flat and projecting in a slender, acute anteroventral process. Aedeagal complex (Fig. 5) with short, ventrally rounded phallophore. Distiphallus composed of a dorsal sclerite armed by some teeth and projections and a larger ventral sclerite connected with apical, less sclerotized part. Postgonite very robust and wide, subapically somewhat widened, with several minute setulae at anterior margin; its rounded apex with a small tubercle. Ejaculatory apodeme S-shaped but very slender. Etymology — Named according to acutely projecting anterior lobe of gonostylus. Distribution: USSR (Far East). Discussion •— The species seems to be closely related to the European P. trichopyga, chiefly because of the similar external characters, aedeagal complex and male S5 and S6. See the key for differences between them. 2. Paralimosina altimontana (ROHÁCEK, 1977) (Fig. 76) Limosina altimontana ROHÁŐEK, 1977: 411-415, (male only), 400 (Fig. 15), 412 (Fig. 25), 414 (Fig. 31), 417 (Fig. 39). Paralimosina (Paralimosina) altimontana: ROHÁCEK, 1983: 50 (comb. n.). Type material — Holotype rf : Nepal, Taplejung distr., below Sangu, c 6000 ft., 30 10 1961, by stream in shady ravine, Brit. Mus. East Nepal Exp. 1961-62, R. L. Coe leg. (BMNH) (examined). New records — Nepal : 28°00'N, 85°00'E, 1 rf 20. May 1967, 10,500 ft., Malaise trap 6, Can. Nepal Exped. (BRI). Pakistan: Swat, Maiam Jabba, 1 rf 9. V. 1983, 2300 m (No.4c), Besuchet et Löbl leg. (MHNG). Supplement to description — Male S5 projecting posteromedially only slightly less than that of P. prominens; S6 with a simple, short, transverse, finely haired, membraneous lobe behind its stripe-like ventral part. Male subanal plate with 2 pairs of very widened scale-like ventral setae. The figure of the gonostylus (Fig. 76) is based on a new male from Nepal. The female is unknown. Distribution : Nepal (ROHÁCEK 1977), Pakistan (new). Discussion •— Apparently, P. prominens is the sister-species of P. altimontana; both these species share a similar aedeagal complex, gonostylus, male S5 as well as external characters.
