Comment:
Aleochara lonae
was originally described as a variety of
A. laevigata
, based on
two syntypes
from "M.te Tomor: Abbas Ali,
2000 m
" (
GRIDELLI 1924
). According to the original description, one of the type specimens is deposited in the Bernhauer collection, the other in the Ravasini collection. The latter was located in the collections of the MCSNT. Since it is a female, it is not designated as the
lectotype
. The
syntype
and the additional material listed above are not conspecific with
A. laevigata
, but represent a distinct species.
The details indicated in the original description of
A. gridellii
BERNHAUER 1936
, which is based on material from the same locality, probably even from the same sample ("Tomorica (Abas Ali), 1922, Ravasini"), as well as from "
Mazedonien
: Peristeri, Meschnigg" (BERNHAUER 1936), leave no doubt that this name is a synonym of
A. lonae
. In fact, it does not seem unlikely that the
syntype
of
A. lonae
in the Bernhauer collection is identical to one of the
syntypes
of
A. gridellii
.
Redescription:
Body length: 3.0-
5.8 mm
. External characters as in
A. laevigata
, but distinguished as follows:
Elytra without reddish spot, either completely black or posteriorly with weakly delimited darkbrown area. Antennae on average shorter; antennomere IV transverse; X almost twice as wide as long.
♂
: sternite VIII as in
Fig. 114
; median lobe of aedeagus approximately
0.72-0.95 mm
long, at base of ventral process with pair of pronounced dark carinae (
Figs 115-117
).
♀
: spermatheca smaller, less slender, with longer distal cuticular intrusion, and with distal portion of capsule of different shape (
Fig. 118
).
Distribution and bionomics:
Aleochara lonae
is currently known only from the southern Balkans (
Albania
,
Macedonia
,
Greece
) (
Map 4
). All the records are from higher elevations (
1690-2000 m
).
