i.e. eyes not reduced. Arista with 0.015 mm long cilia. Thoracic chaetotaxy as in its congeners (2 pairs of dc, no prst, etc.). Sternopleural birstle rather thin and comparatively short, only 0.16 mm. Apical scutellar 0.57 mm, basal scutellar pair 0.34 mm (holotype). Costal vein dark brown, other veins light brown to ochreous, plane of wings dark brown. It is a brachypterous species, i.e. venation is complete (Fig. 1), wings are rounded, veins are comperatively thick. Discal cell with two distal appendages, bristles mgj almost as long as basal bristle (this latter is the shortest in the reduced-winged forms of this species-group). Middle tibia with anterodorsal and posterodorsal bristle pairs at upper third and at distal 7/9. Male 5th sternum (Fig. 2) resembling to that of P. beckeri but more transverse; posterior medial lobe longer, more sparsely pilose and also slightly different in s hape; in addition, the medial row of robust spines in front of the medial thick (stripe) is terminated laterally by a single longer spine (2-3 in beckeri) and posterior margin displaying a distinct transverse, pale pigmented and finely pubescent area. Periandrium, hypandrium and pseudocerci as in P. beckeri incl. their chaetotaxy. Telomere (surstylus) (Fig. 3) very similar to that of P. beckeri but somewhat longer (higher), particularly at posterior lobe; its anterior lobe relatively large and carrying more setae than that of P. beckeri

. Micropubescence not developed on posterior lobe. Aedeagal complex (Fig. 4) with phallophore and distiphallus formed as in P

. beckeri (see PAPP and ROHACEK, 1981) except for the armature of apical part of distiphallus. Postgonite (Fig. 5) slender, long and with simple apex but without subapical tubercle (cf. Fig. 19 of PAPP and ROHACEK, 1981), thus rather resembling that of franzi

. Ejaculatory apodeme present but small. Holotype male: Canary Is., La Palma, Strasse von Sta. Cruz zum Tunel de la Cubre, Gesiebe aus Laubstreu unter Castanea und Lorbeer, 17.2.1982 (Sp 1486-88), leg. H. Franz. Paratypes: 5 cf: data same as for the holotype. The new species is extremely similar to P. beckeri and it forms undoubtedly its closest known relative. There is a considerable resemblance in the formation and armature of male genitalia (e.g. telomere, aedeagus) but also in the cephalic and tibial chaetotaxy. However, it can be easily recognized by its reduced and very dark wings and relatively stout body apart from other differences in the armature of the male 5th sternum and the shape of its posterior lobe, in the length of telomere and the difference in the form of the apical part of postgonite. Paralimosina franzi L. Papp & Rohácek, 1981 (Figs 6-7) Material studied: 3 ci: Tenerife, Anagagebirge, Barranco de Iguana oberhalb des Barrio de Punta Anaga, Gesiebe aus feuchter bis nasser Lorbeerwaldstreu, 25.2.1982 (Sp 1493). The original description (L. PAPP & ROHACEK, 1981, p. 146) was based on a single pair of severely damaged specimens. The three males collected recently by Prof. H. FRANZ enabled us to supplement it as follows: Male 5th sternum (Fig. 7) characterized by its comparatively small posteromedial lobe with long micropubescence on posterior margin and by a rather uniform ^ row of thick spines in front of the medial, darkly pigmented thick (stripe), these spines lengthening laterad. Telomere (surstylus) (Fig. 6) with long setiform hairs not only on the upper part of posterior lobe but there are two hairs also above the anterior double-pointed spine and other two at ventral margin of the posterior part. Around the posterior robust spine there is an area covered by rather long micropubescence (longest among the species of this group). Discussion. - The new species, Paralimosina avolans sp.n., described here, is the seventh species of the Paralimosina beckeri-group. It belongs to the first subgroup of L. PAPP & ROHACEK (1981), which comprises also P. beckeri, P. gomerensis and P. franzi. Of these, P

. beckeri seems a widely distributed species known from the majority of the islands of the Canaries (see also new records above), while the other three species (all brachypterous) are limited to different islands (

P. avolans sp.n. is endemic for La Palma, P. franzi to Tenerife and P. gomerensis to La Gomera). Apparently their common ancestor was a macropterous species similar to that of P. beckeri. It is very interesting, that the other two brachypterous species (forming the second subgroup) also occur on Tenerife (P. pilifemorata

) and La Gomera (

P. anaptera) and thus is seems highly probable that they evolved from a different, fully winged, ancestral species. The seventh species from La Palma has not been described and it is yet unplaced in any of the subgroups owing to insufficient material for study (see L. PAPP and ROHACEK, 1981). This discussion is designed to correct some mistakes involved in the discussion of L. PAPP and ROHÁCEK.
