Type locality: Cape of Good Hope; holotype in ZMUC. Pseudoxestomyza longirostris Kröber, 1912: 12 ; Lyneborg 1972: 357 . Type locality: Algoa Bay; holotype in NHMW. Figs 3, 4. Xestomyza lugubris Wiedemann , habitus, dorsal: (3) male, overall length 11 mm; (4) female, overall length 9 mm. Lyneborg (1972) gave a detailed redescription of this species, with illustrations of the male terminalia and head. One illustration he provides ( Lyneborg 1972: 356 , fig. 187) supposedly illustrates a male head in lateral view, but it is clearly a female specimen and not identical with the male specimen in fig. 186. The setae on the frons and the dorsal part of the scape are much longer and erect in males, whereas they are short and virtually appressed in females ( Figs 9, 11 ).
