Scale line mm. is, however, not conspecific but more likely to be nigrofuscum of Lundstrom (1909). Zaitzev's species has been found in Britain and is here described as new. Exechia bicincta (Staeger) The interpretation of this name follows Edwards (1924), who examined Staeger's types (ZMUC). These comprise two specimens, labelled respectively as male and female and the usage is based on the first of these. Edwards proposed the name dizona for bicincta sensu Lundstrom (1909). He evidently did not examine the "female" specimen as I have found this to be a male of E. dizona. Unfortunately, Staeger's description refers only to the female and his "male" must have been added later, so the dizona male is more likely to be the type. As this cannot be certain, I have not selected a lectotype in order to maintain current usage. Exechia chandleri Caspers The male genitalia were figured by Caspers (1987). It has been found at several wooded and wetland sites in southern England. British material of E. chandleri (1 male at each site):.
