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

his abbreviations used in descriptions, with two exceptions: the ventral clasping appendages of male genitalia are called gonostyli (= telomeres of ROHÁCEK, 1983; surstyli auct.) and the last female postabdominal sclerites are called the 10th tergum and sternum (770, S10) respectively (= T9, S9 of ROHÁCEK 1983; supraanal and subanal plates auct.). The types and other materials examined are deposited in the following museums and collections: BMNH — British Museum (Natural History), London (UK); BRI — Biosystematics Research Institute, Ottawa (Canada); GUE — Department of Environmental Biology, University of Guelph (Canada); HNHM — Hungarian Natural History Museum, Budapest (Hungary); JRO — J.

Diagnosis — The genus is defined as follows: (1) pvt small or absent; (2) 1-2 ors; (3) 2-5 ifr of which 1-3 posterior strong; (4) frons usually with dark M-shaped mark, absent in some species; (5) 1-2 dc, the anterior always short; (6) 6-12 rows of ac microsetae; (7) 1-2 stpl, the anterior minute or absent; (8) scutellum flat, more or less semicircular, rarely shortened (P. ceylanica); (9) male /i and/

3 often thickened; (10) t

2 chaetotaxy characterized by 3 unpaired proximal bristles and an anterior seta in distal group of bristles; ventral side with or without mid ventral seta; (11) wing (if present) with C not extending beyond apex of R4+5; (12) R4+5 in fully winged species sinuate; (13) discal cell short and broad, usually with extensions of Ml +2 and M3 —4 beyond tp; (14) alula small, narrow; (15) abdomen with large, heavily sclerotized terga; (16) male S5 without additional structures but sometimes posteromedially prolonged; (17) ventral stripe-like part of male S6 sometimes with processes but always with short, membraneous, finely pubescent lobe(s); (18) periandrium ball-shaped, uniformly setose; (19) hypandrium with robust bifurcate ventral appendage or process; (20) male subanal plate ( = cerci of ROHÁCEK 1982) with one pair of long caudal setae and 2 pairs of closely set ventral setae which are sometimes modified to flat, scale-like bristles; (21) gonostylus short, bilobed, anterior lobe flattened and without long setae, posterior lobe darker, long setose; (22) phallophore very short, kidney- to sickle-shaped in profile; (23) distiphallus complex, with various processes; (24) postgonite usually slender and more or less bent; (25) ejaculatoryapodeme well developed; (26) female postabdomen short, suddenly tapered posteriorly; (27) female 77 extended laterally; (28) T8 divided into 2 lateral sclerites; (29) 770 relatively short and usually pale; (30) S8 usually long and tapered posteriorly; (31) SW large, anteriorly with a deep incision or emargination; (32) spectacles-shaped sclerite well developed; (33) accessory gland (Figs 41, 80, 131) similar in all species, hyaline, elongate spindle-shaped, with ringed surface; (34) spermathecae vesiculate, often with wrinkled surface, with terminal and/or basal invaginations and sclerotized terminal parts of ducts often bulbously dilated ; (35) female cerci with sinuate hairs. Discussion — The genus, in the present concept (incorporating Hackmaniella and Nipponsina), is clearly a monophyletic unit well-defined by several apomorphic features, the most important of which seems to be (19)—presence of a ventral appendage of hypandrium. Other highly diagnostic, though less unique characters are 10, 16, 17, 20-22, 31 and 32 (see above diagnosis). Most probably Biroina RICHARDS, 1973, with a frons
