marci, nor partly white aa in hortulanua, nor rufous aa in hortulanua females. Ocellar triangle shining black, strongly projecting, 0,20 mm long. Apical segment of palpi of males flat, 0.31 mm long and 0.08 mm wide on holotype. Thorax subshining. Wings tinged yellowish grey, radial veins light brown, m-s and cu-s colourless, costal spot dark brown. Veins m^ and m

2 extending to margiri. Vein br 0.46 mm on holotype, 0.60 mm on a paratype female, t

a 0.15 mm on holotype, 0.23 mm on a paratype female, i.e. br thrice or almost thrice longer than t

a

. Haltères dark grafite-grey, calyptrae dark grey. Spurs on fore tibia sharply pointed. Also male legs black except for fore tarsomeres on their apical parts. Dorsal apical spur of male fore tibia about twice longer than ventral thorn. Basal half of male hind femur thin, thickening only at middle (in marci at proximal 2/5!). Longest hairs on male fore coxa 0.86 mm. Male hind basitarsus 0.91 mm long (holotype) and only 0.17 mm wide, i.e. not swollen. Female tibiae and tarsi somewhat lighter, i.e. dark brown with some rufous hue, hairs of body and hairs on other parts white or yellowish, frons shining. Costal spot of wings elongated reaching conjointment of rs, m and cu veins ochreous. Female cerci not much longer (0.34 mm) than wide (0,24 mm). Flagellum of antennae with 7 segments in both sexes. Male 9th abdominal tergum (Fig. F and G) caudally with a deep but wide emargination of characteristical shape, highly different from that of B. marci L. (Figs. A and D). Bristles on male cerci as long as length of cerci. Surstyli (claspers) (Fig. H) much smaller than those of marci (Figs. B-C and E), their apical part thinner. Holotype male: Tenerife, Teide - N-Hang, 1000-1600 m (on the other side of label in blue ink: "Sp 1033"; 2/ "Bibio Marci LINN. ?" Det 1978 D.E. HARDY. Paratypes: 3d, 3 o-: data same as for holotype. The holotype and two male and female paratypes each are deposited in Prof. H. FRANZ'

s collection, one male paratype in the Hungarian Natural History Museum, one male and one female paratypes are in the collection of Prof. D.E. HARDY in Hawaii. There was an additional female specimen of Bibio in this material: "El Hierro, Umg. San Andras" 2/ Kanarische Inseln, leg. H. FRANZ "Sp. 1363"; this may belong to this species but considerably bigger (9.65 mm!), so it was not involved in the type-series. Bibio elmo

i sp.n. belongs to the marci-hortulanua species-group (vein br much longer than t

a

, eux reaching wing margin, outer apical spur on male fore tibia twice longer than inner spur, etc.); its closest relative is probably B. marci L. but it is smaller, hairs of male body and legs are grey (black in marci) . The reliable differentiating characteristics are the shape of tergum 9 and the male surstyli (claspers). The posteromedial cleft of tergum 9 of marci is rather normal U-shaped (Figs. A and D). The shape is somewhat variable but the tergum 9 of the Hungarian specimens seems essentially the same as that of the specimens from the European part of the USSR (see KRIVOSHEINA, 1970: 1: 438, Fig. 254/2) and much different from that of B. hortulanus (ibid., Fig. 254/3). The tergum 9 of B. elmoi sp.n. is not as wide but the cleft is deeper and different in shape (Figs. F and G). The shape and armature of male surstyli (claspers) of the new species (Fig. H) are rather different from those of marci: the apical half of surstyli is more slender and somewhat more curved (cf. Figs.B-C and E). I dedicate the new species to Professor D. Elmo HARDY, University of Hawaii, Department of Agriculture, one of the leading dipterists of the world, who is an excellent specialist also on bibionids. Remark. As early as in 1960, HARDY and TAKAHASHI noted that "the common bibionid species of Europe are obviously not so widely distributed as has been previously thought". We are still in need of a modern revision of the European bibionids, first of all as regards the species related to the above new species, namely the Mediterranean and South Palearctic forms, which were regarded or described as "varieties" by DUDA (1930). The first steps have been made by KRIVOSHEINA (1970), who published drawings of male genitalia of numerous European species. LONCHAEIDAE * Lamprolonchaea aurea (Macquart, 1850) - 2 (j>: Isla del Hierro, Las Playas, leg. FRANZ, Sp. 1355, "urn Euphorbia regis jubae". It is a widely distributed species in the Canaries (FREY, 1958). • t Determined by Dr. A. SOOS.
