(Sichuan,
Fig. 24
).
Remarks.
By its bare M and Cu wing veins, an inflated gonostylus, an apically located dorsal lobe with five long magesetae, and a richly setose intercoxal lobe on the hypopygium, the new species is similar to
P. plusiochaeta
Hippa & Vilkamaa, 1991
. But it differs from
P. p l u s i o c h a e t a
by a wider dorsal lobe on a more strongly inflated gonostylus, five much longer megasetae on the dorsal lobe, a tegmen with medial shoulders and a narrower intercoxal lobe on the hypopygium.
Etymology.
This species is named after its long megasetae on the dorsal lobe on gonostylus, from the Latin adjective
longispinus
, meaning long megasetae.
