Diagnosis. Dactyloscirus dolichosetosus resembles D. humuli , D. smileyi and D. condylus in that it possesses long lateral platelets but lacks a median shield. It can be distinguished from D. humuli and D. smileyi by the length of setae f1 and h1: f1 is shorter than h 1 in D. humuli and D. smileyi but equal in length in D. dolichosetosus . Dactyloscirus dolichosetosus possesses one telofemoral apophysis whereas D. condylus possesses a second flattened apophysis basally.

Remarks. Until recently this species was reported only from South Africa by Den Heyer (1979). The range expansion presented here, combined with Castro (2008) who reported it from Brazil, suggest it may have a much wider, possibly cosmopolitan, range. Den Heyer (1979) provides an abundance of illustrations and SEM images.
