[p] 2009 [w, h]’ ( MNHN – coll. Pic). Distribution. Algeria and Morocco ( REGALIN & MEDVEDEV 2010b ). 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 .
