Type material.

Lectotype ♀ from southern Germany most probably lost ( Papp 1985a); the only paralectotype (♂, ZMB) is a melanistic male of A. coxalis (Spinola, 1808) which does not fit the original description. The paralectotype was listed as A. tristis Wesmael by Papp (1985a).

Additional material.

Papp J., 1984"; 1 ♂ (MTMA), "[Hungary:] Nadap, 19-21.iv.1951, Móczár Bajári”; 1 ♂ (ZSSM), "[?

Molecular data.

None.

Biology.

Unknown. Specimens of both sexes have been collected in April and May, from which from which it is safe to surmise that the winter is passed in the mummy as the male would not hibernate. But we have seen no reared material nor any indication of habitat for this central European species. Its early flight time might be one reason why it is seldom collected and apparently rare.

Diagnosis.

Maximum width of hypoclypeal depression 0.5-0.6 × minimum width of face; OOL of ♀ 0.8 × (of ♂ 0.9 ×) diameter of posterior ocellus and rugose; ventral margin of anterior part of clypeus comparatively sharp and more or less protruding in lateral view (Fig. 493 ); head rather transverse (Fig. 492 ); mesoscutal lobes coriaceous; precoxal area of mesopleuron rugose medially; vein 1-CU1 0.3-0.4 × vein 2-CU1 and 0.3 × vein m-cu; hind tarsal claws with conspicuous and robust brownish pecten (Figs 494 , 503 ); posterior orbit black; pterostigma of ♀ pale brown medially, of ♂ dark brown; coxae and femora completely black or dark brown; hind tibia usually ivory or pale yellowish basally; 1st and 2nd metasomal tergites of both sexes black. According to Papp (1985) most closely related to A. sibiricus (Kokujev), but that species does not have all black females and has the shape of the clypeus different. According to the original description the pterostigma is yellowish and laterally darkened, 1st subdiscal cell of the fore wing rather short, because vein cu-a distinctly more postfurcal than its own length (ca twice its own length) and meaning vein 1-CU1 of intermediate [approx. 0.6 ×] length of 2-CU1 and 0.8 × vein m-cu] [= "discoidali posterior brevior" as indicated for A. pallidicornis ], precoxal sulcus area rugose medially, 1st tergite twice wider posteriorly than basally, hind leg black, except pale yellowish dorso-basal area of hind tibia and palpi dark brown. Here we accept the interpretation of the first reviser ( Szépligeti 1906) despite the difference in the shape of the 1st subdiscal cell, because it may be part of intraspecific variation.

Description.

Redescribed ♀ (MTMA) from Hungary (Budapest). Length of fore wing 7.5 mm, of body 9.4 mm.

Head. Antenna incomplete, 47 segments remaining (54 in lectotype), length of complete antenna approx. 0.9 × fore wing, its subbasal and subapical segments short; frons largely rugose; OOL 0.8 × diameter of posterior ocellus, and mainly rugulose and with satin sheen; depression near posterior ocellus smooth; vertex densely rugulose and with satin sheen; clypeus with some punctures; ventral margin of clypeus rather thin and protruding forwards (Fig. 493 ); width of hypoclypeal depression 0.6 × minimum width of face (Fig. 491 ); length of eye 1.7 × temple in dorsal view (Fig. 492 ); vertex behind stemmaticum punctate-rugulose; clypeus largely above lower level of eyes; length of malar space 0.3 × length of eye in lateral view.

Mesosoma. Mesoscutal lobes densely and finely punctate, with satin sheen; precoxal area of mesopleuron widely and densely rugose, but densely punctate posteriorly; middle of mesopleuron densely rugulose and dorsally coarsely rugose; metapleuron largely rugose; scutellum punctate-coriaceous; propodeum rather flat and densely rugose or rugulose, medio-longitudinal carina complete, and without protruding carinae laterally.

Wings. Fore wing: r 0.5 × 3-SR (Fig. 484 ); 1-CU1 slightly oblique, 0.3 × 2-CU1; r-m 0.7 × 3-SR; 2nd submarginal cell robust and posteriorly somewhat diverging (Fig. 484 ); cu-a inclivous, straight; 1-M slightly curved posteriorly; 1-SR wide; surroundings of M+CU1, 1-M and 1-CU1 densely but inconspicuously setose. Hind wing: marginal cell linearly widened, its apical width 2.4 × width at level of hamuli (Fig. 485 ); 2-SC+R short and subquadrate; m-cu present anteriorly; M+CU:1-M = 4:3; 1r-m 0.6 × 1-M.

Legs. Tarsal claws bristly setose, medium-sized, and with robust pecten basally (cf. Fig. 494 ); hind leg missing in redescribed specimen.

Metasoma. First tergite evenly convex, 0.9 × as long as wide apically; 1st tergite with medio-longitudinal carina; 1st and 2nd tergites and basal half of 3rd tergite finely and densely longitudinally rugulose; medio-basal area of 2nd tergite short triangular (Fig. 488 ); 2nd suture distinct and finely crenulate; remainder of metasoma superficially micro-sculptured; 4th tergite without sharp lateral crease; ovipositor sheath wide, with rather long setae and apically truncate (Fig. 483 ).

Colour. Black; palpi brownish yellow, but basally dark brown; tegulae pale yellowish; legs (except pale base of tibiae), metasoma ventrally and veins dark brown; pterostigma brown and medially yellowish brown; wing membrane subhyaline.

Variation. Clypeus distinctly to moderately protruding and ventrally rather thin to thick. Antennal segments of ♀ 51(1), 52(1), 54(1), of ♂ 55(1). Males are very similar to the redescribed female (including the wing venation: Fig. 497 ), apical tergites type 1 with fringe not observed and probably absent (Fig. 498 ), mesopleuron rugulose or punctate medially and pterostigma entirely dark brown.

Distribution.

*Finland, Germany, Hungary.

Notes.

The lost lectotype from Germany had hyaline wings (which separates it from the A. carbonarius / grassator / carbonaroides complex), the pterostigma paler medially than laterally (entirely dark brown), base of the hind tibia pale yellow (black in ♂) and the body of ♀ entirely black (more or less yellowish or reddish).
