Comments.
Both specimens have weak and reduced (about 30 μm long) dorsocentrals (
SOPONIS 1977
) and genitalia compatible with
O.
(
O
.)
rubicundus
(
ROSSARO et al. 2003
)
; the shape of genitalia and the observation that all the other
Orthocladius
species
known from the West Palaearctic possess more robust and longer (about 70 μm long) dorsocentrals allows us to assign both specimens to
O.
