description: Tariqia Rousse et Villemant gen. nov.
(Fig. 20)
Diagnosis. Genus characterized by the combination of the twisted mandible, occipital carina very close to the foramen magnum, mesoscutum with notaulus present basally as a deep punctuation bordered by a short vertical carina on its front side, tergite I fused with sternite, petiolar area of propodeum with a strong median longitudinal carina, areolet closed and petiolate, and long ovipositor.
Description.
Head. Transverse in dorsal view and very strongly constricted behind head; temple virtual, dorsal face of head almost flat and reaching the posterior margin of eyes; occipital carina flanged, very close to the foramen magnum, joining the flanged hypostomal carina far from base of mandible; clypeus large and convex, separated from face by a groove, its ventral margin sub-truncate; clypeal fovea minute in a deep impressed area; mandible thin, bidentate and with apex apparently slightly twisted, lower tooth distinctly smaller than upper; maxillary palpus elongate, five segmented, its apex reaching middle of mesopleuron; labial palpus four segmented; torulus large and flanged, scape large ovate, its apical truncation about 45° from transverse; flagellum without tyloids, bearing erected hairs and dense longitudinal sensillae.
Mesosoma. Pronotum with epomia long and strong; mesoscutum polished, almost bare with notaulus present basally as a deep punctuation bordered by a short vertical carina on its front side; scutellum convex with lateral carinae only at basal corner; mesopleuron polished with sternaulus short but strongly impressed anteriorly; propodeum polished with strong carination; anterior transverse carina entirely lacking, petiolar area with a strong median longitudinal carina. Legs rather slender, hind femur sub-clavate and hind tibia clavate; apical fringe of hind tibia dense and slightly oblique; tarsal claws simple, elongate. Fore wing with areolet large and closed, rhombic and shortly petiolate, 2m-Cu with two bullae, arising after middle of areolet; cu-a barely distad to Rs&M; hind wing with M+Cu strongly elbowed at its posterior fourth; 1/Cu&cu-a angled posteriorly, Cu1 absent.
Metasoma. Metasomal tergite I moderately long and slender with spiracle at middle; glymma absent, ventrolateral carina strong; sternite 1 fused with the tergite and ending at spiracle level; tergite II smooth without thyridiae, with a pair of oblique smooth grooves at its base, its laterotergite separated by a crease; tergite III without crease; hypopygium short and medially membranous; ovipositor long and thin, slightly upcurved at its basal third, and lacking a sub-apical notch.
Comments. This genus shares several characters (occipital carina very close to foramen magnum, temple very short, glymma absent, petiolar area with a strong median longitudinal carina) with Sphingozona Townes. However, it differs by its shorter antenna and maxillary palpus, mesoscutum with short and deep notauli bordered by a frontal carina, short and deep sternaulus, propodeum without deep anterior transverse groove, fore wing with an areolet and tergite I separated from the laterotergite by a crease. The shape of notauli and the absence of anterior transverse carina in propodeum relate Tariqia to some Plescidea species and the genus Aniseres; this last genus however has the sternite 1 free from the tergite and the tergite III with laterotergite separated by a crease, while in Plesticidea the laterotergites of second and third tergites are not separated by a crease. Tariqia cannot therefore be attached to any other Orthocentrinae genus.
Etymology. Dedicated to Tariq Aït Lemkadem.
