Pseudogonalos is treated as a separate genus on sound phylogenetic ground by Carmean and Kimsey (1998) (it is not even considered to be in the same tribe as Trigonalys ). Trigonalis is an incorrect spelling of Trigonalys . Although the former range was evidently extensive, this species may now be restricted in Britain to southern England and South Wales, with the most recent published records being by Shaw (1990) and Howe and Howe (2005) .
