No full textDinetus tunisiensis Khedher et Mokrousov, sp. nov. (Figs 8–16) Diagnosis. A member of the D. cereolus species group, which includes also D. venustus de Beaumont, 1957, D. cereolus Morice, D. pulawskii de Beaumont, 1960, D. nabataeus de Beaumont, 1960, D. porcellaneus Guichard, 1980 and is characterized by having the apex of the marginal cell and second section of the cubital vien of the subdiscoidal cell oblique (Fig. 12); females (and males except D. venustus) have smooth and shiny head and mesosoma with very sparse microscopic points and setae (except spots of appressed silvery pubescence) (Figs 8–11; 14–16); males have flagellomere I elongate, comparable in length with the scape. From all species of the cereolus group, it differs by its greater ocellocular distance (Fig. 9 vs Fig. 17) and dark coloration (mid and hind femora completely black; metasoma black with white lateral spots only on tergum 2).

Occipital area, mandible, mesosoma, fore coxa and wings as at female. Coloration similar to female (Fig 14), but yellow coloration more developed on head (mandibles, except apex, clypeus, lover frons and gena are yellow), fore femur with obscure apical spot. Pronotal tubercle black or with yellow edge. Etymology. The specific name means in Latin “from Tunisia ”. Distribution.

No full textLeptochilus (Lionotulus) leleji Fateryga, sp. nov. (Figs 6–8) Diagnosis. Head slightly wider than long; labial palpi not modified; temples with small unnoticeable pubescence posteriorly; pronotal carina weakly lamellate; pronotum laterally 1.5× as long as tegula length; tegula 0.8× as long as scutellum length, its outer margin evenly rounded posteriorly; ventral mesepisternum with large and sparse punctures, interstices exceed diameter of punctures and have distinct microsculpture; metanotum sharply truncated posteriorly; propodeal concavity not sharply edged laterally; hind trochanter rounded posteriorly; tergum 1 with distinct punctures; apical lamella of tergum 2 weakly sclerotized, semitransparent, with row of tiny basal punctures. Among other species of the genus Leptochilus de Saussure, 1853 occurring in Russia and neighboring countries, the new species is somewhat similar to L. (Lionotulus) alpestris de Saussure, 1855 [the latter have the head somewhat longer than wide, pronotal carina not lamellate, pronotum laterally nearly 2× as long as tegula length, punctures on ventral mesepisternum denser (interstices not exceed diameter of punctures), and propodeal concavity sharply edged laterally].

Dorsal and especially ventral mesepisterna with punctures sparser than on mesonotum. Dorsal surface of scutellum nearly flat. Hind surface of metanotum (behind truncated edge) with coarse shallow sculpture above and smoothed unclear sculpture below. Sculpture on propodeum like that on clypeus. Propodeal concavity with median carina; dorsolateral parts of propodeum rounded. Legs from femora to tarsi with short pale pubescence. Metasoma with pubescence as on legs. Punctures on tergum 1 small sparse, interstices reach several diameters of punctures, having distinct microsculpture. Main sculpture on tergum 2 finer and sparser than on tergum 1. Sternum 2 rounded in lateral view, sculpture as on tergum 1. Basal color black. Apical bands on terga 1–2 whitish-yellow. Tegula and legs from distal ends of femora ferruginous.
