Bidessonotus bicolor Guignot, 1957 View in CoL Figs 19, 31
Bidessonotus bicolor Guignot, 1957: 36; Young 1969: 2; 1990: 378; Biström 1988: 18; Nilsson 2016: 99.
Diagnosis.
Bidessonotus bicolor is inadequately known and a diagnosis is difficult to establish. The apical blade of the male median lobe is relatively small with a spinous process at the apicoventral angle, a triangular prominence medially on the distal margin, and a pointed dorsal apex (Fig. 19).
Discussion.
The type was not found and no other specimens were examined by Young (1990), who thought the species might be based on a teneral specimen of Bidessonotus melanocephalus . No specimens were examined for this study either.
Distribution.
Known only from the type locality, Brazil, Pará, Cachimbo (Fig. 31).
