( Figs 2–6 View Figs 2–6 )

Type material. HOLOTYPE: ♀, “ Maroc NW – Sud Nador , Mechra Hamadi, leg. G. Sama ”, “ex larva Tetraclinis articulata (Vahl) Masters   , 15.vi.1989 ”, “ Lucasianus levaillanti Lucas   , leg. G. Sama ” ( UAIC).  

Description. Body length. 8.5 mm ( Fig. 2 View Figs 2–6 ).

Colour. Head with face golden green near mouth and gradually becoming reddish-violet between eyes; clypeus with golden and reddish reflections; interantennal region reddish-violet between toruli and becoming mainly golden green on scrobes; vertex violet; eyes and ocelli pale orange; antenna with scape reddish-brown, with distinct blue-violet reflections; pedicel and anellus blue-violet; funicular segments gradually changing from reddish- -brown to blackish; clava blackish, tip lighter; mandibles brown, teeth dark brown. Mesosoma dorsally violet with golden-green and bronze reflections mainly on anterior part of pronotum, central lobe of mesoscutum, inner part of axillae and central part of scutellum; notauli turquoise; propodeum bronze violet, with some blue and golden reflections anteriorly; legs with fore and middle coxae as mesosoma; hind coxae laterally bronze, dorsally green, blue and violet; trochanters, femora and tibiae uniformly reddish-brown; tarsi paler basally and with dark brown tips; fore wing hyaline, with two brownish maculae: large macula below postmarginal and stigmal veins and reaching middle of wing disc, and smaller macula between middle of cubital fold and hind margin of wing; hind wing hyaline; tegula reddish-brown; venation brown. Gaster black, with some bronze and violet reflections. Body setation white, except for brown setae on distal gastral tergites; wing setation brown.

Head ( Fig. 3 View Figs 2–6 ). Frons and vertex densely reticulated, alveoli clearly defined by smooth raised walls; clypeus shallowly striate-reticulate; scrobes conspicuous, punctuate-reticulate; gena almost smooth posterior to malar sulcus. Clypeal margin straight. Interantennal crest triangular, broad. Toruli below lower eye margin. Eyes in frontal view strongly divergent in lower part, inner margin sinuous. In dorsal view temples absent and occiput slightly convex. Antenna ( Fig. 3 View Figs 2–6 ) with all funicular segments longer than broad; clava clearly overpassing laminar process of F7. Setation conspicuous, dense. Relative measurements: length: 31; width: 69; height: 47; minimum distance between eyes: 29; POL: 12; OOL: 4; diameter of lateral ocellus: 6; eye height: 32; eye length 25; malar space: 18; mouth width: 30; scape length: 28; pedicel plus flagellum: 70; F1 length: 9; F1 width: 5; F7 length (including laminar process): 9; F7 width: 5.5.

Mesosoma ( Fig. 4 View Figs 2–6 ). Pronotal collar striate-reticulate. Mesoscutum, axillae and scutellum densely reticulated. Central part of scutellum about as densely reticulated as central lobe of mesoscutum. Notauli reaching about middle of mesoscutum. Dorsellum almost smooth. Propodeum with median carina straight and thin, crenulated groove at anterior and posterior margins, and conspicuous crenulated spiracular sulci; central area and callus finely reticulated, hence appearing shinier than scutellum. Prepectus, most parts of mesopleura, and metapleura densely reticulated. Setation of mesosoma less conspicuous than on head, except on sides of pronotal collar, propodeal callus and dorsal side of hind coxae where setae are longer.

Fore wing ( Fig. 6 View Figs 2–6 ) with basal cell setose except for narrow band distally below SMV; speculum as narrow band below parastigma and proximal half of MV; costal cell with a few rows of setae along its entire length; distal half of SV virtually parallel with PV. Relative measurements: length: 105; width: 61; mesoscutum length: 36; scutellum length: 35; scutellum width: 34; propodeum median length: 12; fore wing length: 200; fore wing width: 68; costal cell length: 83; costal cell width: 8; MV: 35; SV: 17; PV: 20.

Gaster ( Figs 2, 5 View Figs 2–6 ) flattened dorsally, with gt 5 slightly convex. Gt1–6 punctuate and with a smooth band posteriorly; gt7–8 almost smooth. Lateral sides of tergites with long pilosity. Ovipositor sheaths slightly protruding in dorsal view. Relative measurements (tergites measured along median line): length: 220; width: 60; gt1 length: 25; gt2 length: 13; gt3 length: 16; gt4 length: 25; gt5 length: 80; gt5 width: 60; gt6 length: 35; gt7 length: 8; gt8 length: 13.

Differential diagnosis. The new species differs from all described Palaearctic species of Cleonymus   mainly as follows. From C. canariensis Hedqvist, 1983   it differs mainly in having denser reticultation on dorsal side of mesosoma and gaster; different colour of flagellum (gradually changing from reddish-brown to blackish versus uniformly dark brown), mesosoma (violet with goldengreen and bronze reflections versus green with bronze reflections), hind femur (uniformly reddish-brown versus with dark brown macula distally), and fore wing (large macula extending posteriorly to middle of wing versus extending much further, to distal end of cubital fold); funicular segments longer than wide versus quadrate to slightly transverse; different sculpture of propodeum (with crenulated groove at both anterior and posterior margins versus with crenulated groove only at anterior margin; median area reticulated versus almost smooth); POL 3× OOL versus 2×; MV 2.05× SV versus 1.2‒1.3×; larger size (8.5 mm versus 5.0 mm); and quite different host associates (large Cerambycidae   in trees versus Anobiidae   in Lavandula   ).

From C. balcanicus Bouček, 1972   it differs mainly in the colour of fore wing (large macula present only below PV and SV versus large macula extending to parastigma); POL 3× OOL versus 1.7×; combined length of pedicel plus flagellum about equal to head width versus about 0.8× head width; funicular segments longer than wide versus moderately transverse; MV 1.75× PV versus 1.18×; gaster about 1.6× as long as head plus mesosoma versus 1.1–1.2×; gaster length 3.6× width versus 2.6×; gt5 length 1.3× width versus 0.89‒0.95×; larger size (8.5 mm versus 4.4‒5.6 mm).

From C. brevis Bouček, 1972   , C. laticornis Waker, 1837   and C. obscurus Walker, 1837   it differs in many character states, especially the sculpture of frons (reticulated versus rugulose), the colour of fore wing (without any white setae versus with at least some dense white setae on the hyaline spot below MV), shape and sculpture of gt5 (much longer than broad and distinctly sculptured versus broader than long and with weaker sculpture), and in smaller ocelli (diameter of lateral ocellus 1.5× POL versus 1.15×). The new species also differs from the two described Afrotropical species of Cleonymus   ( C. albomaculatus Hedqvist, 1960   and C. viridicyaneus Risbec, 1952   ) in many aspects, especially colouration of the head, antenna, mesosoma and fore wing, and the shape of antenna and gastral tergites.

Etymology. The name of the species refers to its long gaster; noun in apposition.

Insect hosts. The new species was reared from Lucasianus levaillanti (Lucas, 1849)   ( Coleoptera   : Cerambycidae   ) on the sandarac tree (Barbary tuja) Tetraclinis articulata (Vahl) Masters   ( Cupressaceae   ) near Mechraa Hammadi (Eastern Morocco).
