Type material.

Lectotype of R. periscelis , ♂ (ZMB), "[Austria:] Neusiedler See", “Type”, "Coll. H. Rhd.", “26696”, " periscelis Gir. [= from Giraud]", "Lectotypus Rogas periscelis Rhd., 1863, ♂, Papp, 1982", " Aleiodes periscelis Rhd., ♂, det. Papp J., 1983"; 2 ♂ paralectotypes (MNHN), one with "[Austria:] Prater, Mai", "ex coll. Giraud". Holotype of R. jaroslawensis , ♀ (ZISP; examined photos made by K. Samartsev), "[S. Russia:] Berditsino [Yaroslavskiy rayon, 57.454N, 40.108E], 22.vi.1892, A.M. Yakovlev, 1909", " Rh. jaroslawensis Kokw., No. 1909" and with a round golden label.

Additional material.

Czech Republic, Germany, Hungary, Russia. Specimens in ALC, BZL, MTMA, NMS, SDEI, ZISP, ZMB, ZSSM.

Molecular data.

None.

Biology.

Unknown but presumably univoltine. Specimens of both sexes collected in April and May suggest that the winter is passed in the mummy. We have not seen reared material, but several Hungarian specimens appear to have been collected in Quercus -dominated woodland, but without indication of any association with Quercus as such.

Diagnosis.

Maximum width of hypoclypeal depression approx. 0.4 × minimum width of face (Figs 573 , 584 ); OOL of ♀ 1.5 × as long as diameter of posterior ocellus (Fig. 585 ; of ♂ 1.4 ×; Fig. 599 ), rugulose or rugose and with satin sheen; ventral margin of clypeus thick and not protruding anteriorly (Fig. 586 ); mesoscutum remotely punctulate and with satin sheen, interspaces of lateral lobes largely smooth, of middle lobe superficially coriaceous; area of precoxal sulcus smooth and shiny; length of vein 1-CU1 of fore wing 0.3-0.4 × vein 2-CU1 and 0.5 × vein m-cu; vein 2-SC+R of hind wing subquadrate; hind basitarsus robust; head (including basal half of mandible) black; antenna of ♀ (except scapus and pedicellus, and apically darkened) brownish yellow; apex of hind femur usually largely black dorsally; basal half of hind tibia (largely) pale yellowish; fore coxa dark brown; 2nd tergite of ♀ orange or dark reddish brown, of ♂ largely black; 4th-6th tergites of males flat, and with long dense setosity (Fig. 590 ).

Description.

Redescribed ♀ (BZL), Czech Republic (Pisek); length of fore wing 5.8 mm, of body 8.1 mm.

Head. Antennal segments 45 (holotype ♀ of A. jaroslawensis : 42), length of antenna approx. as long as fore wing, its subbasal and subapical segments robust (Figs 587 , 588 ); frons largely smooth anteriorly and with curved rugae posteriorly; OOL 1.5 × diameter of posterior ocellus, rugulose and shiny; vertex finely rugose and with satin sheen; clypeus slightly convex and mainly transversely aciculate; ventral margin of clypeus thick and not protruding anteriorly (Fig. 586 ); width of hypoclypeal depression 0.4 × minimum width of face (Fig. 584 ); length of eye 1.5 × temple in dorsal view (Fig. 585 ); vertex behind stemmaticum rugulose; clypeus below lower level of eyes; length of malar space 0.45 × length of eye in lateral view and 1.3 × basal width of mandible.

Mesosoma. Mesoscutum remotely punctulate and with satin sheen, interspaces of lateral lobes largely smooth, and of middle lobe superficially coriaceous; scutellum superficially punctate, laterally rugose; precoxal area of mesopleuron smooth and shiny; metapleuron largely densely punctate, but ventrally coarsely rugose; metanotum with distinct median carina anteriorly; propodeum rather flat and coarsely vermiculate rugose, medio-longitudinal carina complete, and slightly tuberculate laterally.

Wings. Fore wing: r 0.3 × 3-SR (Fig. 577 ); 1-CU1 horizontal, 0.3 × as long as 2-CU1; r-m 0.6 × 3-SR; 2nd submarginal cell medium-sized (Fig. 577 ); cu-a vertical, straight; 1-M nearly straight posteriorly and subparallel; 1-SR slender; surroundings of M+CU1, 1-M and 1-CU1 densely setose. Hind wing: marginal cell gradually widened (but less so in its basal third) and apical width 2.2 × width at level of hamuli (Fig. 578 ); 2-SC+R quadrate; m-cu short; M+CU:1-M = 40:33; 1r-m 0.5 × 1-M.

Legs. Tarsal claws with conspicuous and medium-sized brownish pecten, remaining removed from tarsal tooth (Fig. 589 ); hind coxa largely coriaceous-punctate, but dorsal besides smooth depression rugose; hind trochantellus rather robust; length of hind femur 3.7 × its width.

Metasoma. First tergite rather flat posteriorly, wide subbasally and 0.9 × longer than wide apically; 1st and 2nd tergites with coarse medio-longitudinal carina and coarsely longitudinally rugose, but posterior quarter of 2nd tergite rather finely rugose; medio-basal area of 2nd tergite triangular and wide (Fig. 581 ); 2nd suture moderately deep, finely crenulate and narrow; basal two-thirds of 3rd tergite finely longitudinally rugose, remainder of metasoma superficially micro-sculptured and with satin sheen; 4th and apical half of 3rd tergites without sharp lateral crease; ovipositor sheath wide, with rather long setae and apically truncate (Figs 574 , 576 ).

Colour. Black; palpi dark brown basally and remainder pale brown; antenna (except dark brown scapus and pedicellus), tegulae (but anteriorly dark brown), middle and hind trochanters and trochantelli brownish yellow; fore coxa, trochanter and femur dark brown; basal 0.4 of hind tibia ivory and remainder black; remainder of legs (but hind femur with a blackish patch dorso-apically), 1st and 2nd tergites and basal two thirds of 3rd tergite, largely dark reddish brown; pterostigma dark brown; veins mainly yellowish brown, but medially brown (Figs 577 , 578 ); wing membrane subhyaline.

Variation. Holotype of A. jaroslawensis has apex of hind femur yellowish brown (Fig. 574 ). Antennal segments: ♀ 42(1), 45(1); ♂ 50(1), 53(1), 54(2), 56(1). Males appear to have ca ten more antennal segments than females. Male has apical tergites type 1, setae moderately long and fringe not observed, probably absent (Fig. 590 ); antenna rather dark brown, but scapus largely blackish brown and antennal segments slightly slenderer than of female and 1.1-1.2 × as long as fore wing; metasoma black, but extreme apex of 1st tergite yellowish brown; OOL approx. 1.4 × width of posterior ocellus.

Distribution.

Austria, Czech Republic, Germany, Hungary, Russia.

New synonymy.

The ♀ holotype of Rhogas jaroslawensis lacks the antennae, but according to the original description the antenna was 42-segmented, distinctly shorter than the body, reddish brown, except for the darkened apex and the black scapus. This and the other characters still visible agree well with our interpretation of A. periscelis (except that the hind femur is yellowish brown apically); therefore, we synonymise R. jaroslawensis with A. periscelis (syn. nov.).
