Type material.

Lectotype here designated, ♀ (ZJUH), " Tunisie, Sicard", "Type, H.T.", "B.M. Type Hym. 3.c.243", "B.M. Type Hym., Rhogas hemipterus Marshall, 1896", " hemipterus Marsh.", "Marshall coll. 1904-120". Paralectotype: 1 ♀ (MTMA), “Tunisie”, " hemipterus M. coll. Marshall", "Paratypus Rhogas hemipterus Marshall 1897 sp. n. % des Papp J. 1986", "Hym. Type No 10582 Museum Budapest", " Aleiodes ♀ hemipterus Mshl. Det. Papp J. 1991".

Additional material.

1 ♀ + 1 ♂ (MNHN), "[N. Tunisia:] Teboursouk", " Rhogas hemipterus Mrsh.", “Muséum Paris, Coll. J. de Gaulle, 1919" [figured specimens]; 1 ♂ [but metasoma missing] (ZJUH) "Rabat, Maroc [= Morocco], coll. Thery".

Molecular data.

None.

Biology. Unknown. The specimens seen do not have phenological data, and we have not seen reared material. As the female is brachypterous it is likely that the host will be found near the ground.

Diagnosis.

Maximum width of hypoclypeal depression approx. 0.6 × minimum width of face (Fig. 396 ); OOL of ♀ 1.2-1.3 × as long as diameter of posterior ocellus, of ♂ 0.9 × (Figs 397 , 408 ) and finely reticulate-rugose; stemmaticum protruding dorsally; antennal segments of ♀ 46-50 (of ♂ unknown), penultimate segments approx. as long as wide and antenna 0.8 × as long as body; length of malar space 0.3-0.4 × height of eye; mesoscutal lobes densely rugose or rugulose and rather matt, middle lobe with medio-longitudinal ridge or carina, of ♀ surrounded by shallow grooves (Fig. 392 ); propodeum angulate posteriorly (Fig. 392 ); ♀ brachypterous and ♂ macropterous; marginal cell of hind wing of ♀ hardly widened (Fig. 390 ) and of ♂ distinctly widened apically (Fig. 403 ); hind tarsal claws with rather conspicuous pale brown pecten (Fig. 399 ); 1st-3rd metasomal tergites very densely and finely longitudinally rugose; 1st tergite of ♀ 1.0-1.1 × its apical width, of ♂ approx. 1.4 ×; 2nd metasomal suture of ♀ hardly impressed but densely costate, of ♂ medium-sized.

Description.

Lectotype, ♀, length of hind wing 1.7 mm (fore wing missing, but in other specimens ca one-third longer than hind wing and 2.2 mm, brachypterous), of body 7.8 mm.

Head. Antenna incomplete, segments robust; frons largely striate-rugose (but transversely costate in figured ♀); OOL 1.2 × diameter of posterior ocellus, (as vertex) rather finely and densely reticulate-rugose and rather dull; clypeus rugose; ventral margin of clypeus rather thick ventrally and rather forward protruding (Fig. 398 ); width of hypoclypeal depression 0.6 × minimum width of face and long (Fig. 396 ); length of eye 1.2 × temple in dorsal view (Fig. 397 ); vertex behind stemmaticum rather coarsely reticulate-rugose; clypeus near lower level of eyes; length of malar space 0.35 × length of eye in lateral view.

Mesosoma. Antescutal depression distinct; mesoscutal lobes coarsely rugose-punctate (but superficial in figured ♀) and rather matt, middle lobe of pair of submedian grooves (Fig. 392 ); nearly entire mesopleuron (except minute smooth speculum) densely and coarsely reticulate-rugose; scutellum coarsely rugose and without lateral carinae; propodeum coarsely vermiculate-rugose, dorsal face long and rectangularly angulate postero-laterally (Fig. 392 ).

Wings. Fore wing brachypterous, hardly surpassing propodeum (Marshall, 1897): (of ♀ from Tunisia r 0.2 × 3-SR; 1-CU1 distinctly widened and oblique, 0.4 × 2-CU1; r-m 0.8 × 3-SR; 2nd submarginal cell medium-sized (Fig. 390 ); cu-a short, vertical, straight; 1-M straight posteriorly; 1-SR widened; 1st subdiscal cell open apically and posteriorly; surroundings of M+CU1, 1-M and 1-CU1 setose; 2m-cu present as curved and only pigmented vein). Hind wing brachypterous: marginal cell reduced, sinuate and apically narrowed (Fig. 390 ); 2-SC+R quadrate and widened; m-cu absent; M+CU:1-M = 27:13; 1r-m 0.6 × 1-M.

Legs. Tarsal claws with rather conspicuous pale brown pecten, remaining far from apical tooth and much shorter (Fig. 399 ); hind coxa finely and densely reticulate-rugose; hind trochantellus robust; length of hind femur and basitarsus 3.6 and 6.0 × their width, respectively; length of inner hind spur 0.4 × hind basitarsus.

Metasoma. First tergite evenly convex, as long as wide apically; 1st-3rd tergites regularly finely and very densely longitudinally rugose, rather matt and medio-longitudinal carina rather weak; medio-basal area of 2nd tergite triangular and short (Fig. 393 ); 2nd suture shallow; 4th and subsequent tergites superficially punctulate; 4th and apical half of 3rd tergite without sharp lateral crease; ovipositor sheath wide, with medium-sized setae and apically truncate (Fig. 389 ).

Colour. Brown; stemmaticum and ovipositor sheath black; frons, vertex medially, occiput, femora, propodeum, 1st and 2nd tergites somewhat infuscate; wing membrane subhyaline.

Variation. Length of body 7.8-8.8 mm. Antennal segments: ♀ 46(1), 50(1); ♂ unknown. Male is normally winged (vein 3-SR of fore wing 1.5 × vein 2-SR, vein r 0.3 × 3-SR, vein cu-a oblique, vein 1-CU1 narrow and 0.3 × vein 2-CU1) and has marginal cell of hind wing 2.2 × wider than width at level of hamuli (with vein m-cu present anteriorly, 2-SC+R quadrate and M+CU:1-M:1r-m = 40:30:26). Apical metasomal segments of ♂ type 1 and sparsely setose.

Distribution.

Morocco, Tunisia.

Notes.

Marshall (1897) based his description on three females from Tunisia. Papp (2003) listed a female in ZJUH as lectotype, but this was not accepted as a designation by Belokobylskij & Kula (2012). Therefore, the redescribed female above is here designated formally as lectotype and is the same specimen intended to become lectotype by Papp (2003).
