Remarks. The species can be recognised by the differentiated shape and colour of the tarsomeres of fore leg. The Nearctic species were revised by
Snyder (1954)
, who also presented a key to identification with which this species can be identified. It belongs to the
uliginosa
-group of
Lispe
, with a characteristic median basal plate on sternite 5 (Hennig 1960: text-fig. 120). Cercal plate (dorsal and lateral), sternite 5, aedeagal complex and ovipositor (lateral view) illustrated by
Snyder (1954
, figs 25, 40, 54, 68). Keyed by
Vikhrev (2015)
and more recently keyed, redescribed and illustrated by
Fogaça and Carvalho (2018
: figs 6a, 7a, 8a, 12a–f).
