Comments.
We studied the aedeagi of the
type
specimens of all three taxa and consider them similar with slight differences in the width of the apical margin, the depth of the anterolateral incisions, and the width of visible sclerites (
Figs 120–125
). Although available material is limited we treat
L. straminipennis
as a variable species forming local forms. Similarly as in
Tituboea paykullii
(
Lacordaire, 1848
)
and
Clytra novempunctata
, the elytral surface of
L. straminipennis
can be either glabrous (described as
L. octomaculata
), with indistinct traces of setae, or glabrous (described as
L. separata
), or densely pubescent (described as
L. straminipennis
). Also the shape of clypeal excavation and of clypeal processes are variable throughout the populations (
Figs 15–17
).
Lachnaia straminipennis
was described based on specimens with densely pubescent pronotum and elytra. The aedeagus has narrow apical margins, shallow anterolateral incisions and visible sclerites with long and narrow apical processes (see
Figs 124–125
, correctly pictured also by
COBOS (1956))
. The clypeal excavation is regularly concave, apical processes moderately long and wide (
Fig. 15
). The population with pubescent elytra seems to be restricted to northwestern
Algeria
and the adjacent part of
Morocco
.
The population described as
L. octomaculata
is characterized by the aedeagus with wider apical margins, deep and almost rectangular anterolateral incisions, wider and shorter sclerite processes (
Figs 120–121
), glabrous elytra, clypeal excavation regularly concave and clypeal processes short and wide (
Fig. 16
). This population covers most of
Morocco
.
The specimens described as
L. separata
have somewhat intermediate shape of the aedeagus and its sclerites between
L. straminipennis
and
L. octomaculata
(
Figs 122–123
), clypeal excavation with subtriangularly formed base and clypeal processes narrow but longer (
Fig. 17
). Elytra are glabrous in two
syntypes
and with indistinct traces of setae in the third
syntype
. The distribution of this population is unknown.
PIC (1897c)
described
Lachnea separata
from ‘
Andalousie
,? Sicilie’. We treat both localities as patriae falsae as this species occurs neither in
Spain
nor in Sicily.
REGALIN & MEDVEDEV (2010b)
mistakenly published it from
Tunisia
based on
GRASSO (1963)
. Based on the accompanying picture of aedeagus, the distributional data of
L. separata
in
GRASSO (1963)
without any doubts refer to
L. padillai
Tomov, 1982
.
The type specimens of both
Barathraea octomaculata
and
Lachnea separata
bear the labels ‘lectotype’ or ‘paralectotype’ added by J.-C. Bourdonné, but the
lectotype
designations have never been published. Thus we treat all the type specimens as
syntypes
.
