sp. n.
A. Hypopygium; B. Flagellomeres 3–5.
Comments
. The species is characterized by having only one spine on the gonostylus, a wide tegmen with a semicircular structure and rather short flagellomeres with bristle-like hairs, shorter than the diameter of the basal node. It is similar to the Palaearctic species
Psl. unispina
(
Mohrig & Krivosheina, 1983
) and
Psl. microcteniuni
(
Yang & Zhang, 1987
) [after
Menzel & Smith (2009)
]. It differs from both species mainly by possessing a longer spine and a much longer whiplash-hair. It belongs to the
Psl.
bruckii
group sensu
Menzel & Mohrig (2000)
.
