Whilst sorting and identifying Diptera in the collections at Cliffe Castle Museum, 

 Keighley, West Yorkshire, four specimens which key out in Collin (1948) as Lyciella 

 pallidiventris (Fallen, 1820) were identified. Papp (1979a) describes two species of 

 Lyciella very similar to L. pallidiventris. On checking the specimens with this paper 

 I found that they agreed with the description and figures of L. stylala. Subsequent 

 checking of specimens from other collections revealed the presence of the second Papp 

 species, L. subpallidiventris. Specimens of the newly recognized British species were 

 exhibited at the 1991 BENHS annual exhibition and published in the Exhibition Report 

 (Godfrey, 1992). Full details of these species are provided here. 



Lyciella sty lata Papp, 1979 



Very similar to L. pallidiventris. Only separable on the male genitalia. The left 

 gonite is very long and slightly bent at the tip whilst the right gonite is extremely short 

 and hook-like (Fig. 1). These structures are visible without dissection; the long left 

 gonite being particularly noticeable. Further illustrations are given by Papp (1979a). 



L. stylata is known from Hungary, Romania, Czechoslovakia, former Yugoslavia, 

 Austria, Latvia and Estonia. I have also taken two males from Loupiac, near 

 Soilliac, France on 7.vii.l993. British records available to me are as follows (all records 

 refer to single males unless otherwise stated).
