arcticoides was a good species, based on the findings of Alexei Polevoi that 



fasciculatum was not con specific. The British sites are more or less wooded. 



British material of B. arcticoides: 



ENGLAND: Norfolk, Sutton Broad, water traps. 2l.viii 4.i\.l9X9. I male: viii.1990, 

 1 male (A. Foster & I). Procter); Staffs, Sandwell Valley. Malaise trap, vii.1988, I 

 male (M.G. Bloxham). 



Brevicornu glandis Lastovka & Matilc 



The male genitalia were figured by Lastovka & Matile (1974). This is another 

 species added by the NCC wetland surveys and was found at 20 sites in ENGLAND: 

 Berks, Oxon, Norfolk and WALES: Anglesey. It was also found in IRELAND in a 

 survey of the Burren Grikes, County Clare (Chandler el <//.. 2000). 



Brevicornu intermedium (Santos Abreu) 



This is a frequent species which had previously been confused with B. fissicauda 

 (Lundstrom), which is also frequent. Zaitzev (1985) figured it as hissaricum Zaitzev, 

 but this was synonymised by Chandler (1994a) and Chandler & Ribeiro ( 1995). Both 

 species have sternite 8 forked apically and the gonostylus very similar. They are best 

 separated by the sternal process between the ventral lobes of the gonocoxites. deepl) 

 bifurcate with long pointed lobes in intermedium but only narrowly divided into 

 short rounded lobes in fissicauda. Material examined is from southern ENGLAND: 

 Berks, Middlesex, Cornwall, Norfolk and WALES: Anglesey. 



Brevicornu rosmellitum sp. n. (Figs 35-36) 



Brevicornu nigrofuscum: Zaitzev, 1988, misidentification. not (Lundstrom. 1909) 



Male. Head grey dusted. Antenna brownish yellow basally, flagellum dark. 



Thorax grey dusted with yellowish decumbent setae on mesoscutum. the larger 

 marginal and postalar setae darker; 1 pair of strong dark scutellars; 3—4 

 proepisternals; long yellow to brown setae on laterotergite. 



Legs yellow. Tibia 2 with 7 anterior, 3 posterodorsal and 4 posterior setae. Tibia 3 

 with 7-8 anterodorsal, 4-5 posterodorsal and 5 posterior (on apical half) setae. 



Wing clear yellowish, radial veins darker. Crossvein r-m two thirds length of stem 

 of median fork. Posterior fork begins just basad of base of median stem. 



Abdomen mainly grey dusted. Tergites 2—4 with yellow lateral patch occupying 

 about half height of tergite. Genitalia (Figs 35-36) yellow. 



Wing length 2.4-2.6 mm. 



Holotype male, ENGLAND, Oxon, Waterperry Wood, at honey-dew, 12.X.1968 

 (J. Brock, Liverpool Museum). 



Paratypes: 4 males, data as holotype (J. Brock. Liverpool Museum): 1 male. 

 ENGLAND, Oxon, Waterperry Common. 29.ix.1968, (J. Brock, in author's 

 collection). 



Etymology. The specific name is an adjective indicating association with honey- 

 dew. 



Discussion. Zaitzev (1988) figured this species, which he recorded from USA and 

 Canada, and identified as nigrofuscum. The British species figured by Edwards (1925)
