Additional material examined. TURKEY: Bolu: 5 exs. [according to Cuccodoro (pers. comm.) 4 additional exs. in MHNG], Konuralp-Akçakoca, 400 m, 15.V.1976, leg. Besuchet & Löbl ( MHNG, cAss); Zonguldak: 5 exs. [all teneral; according to Cuccodoro (pers. comm.) 43 additional exs. in MHNG], Eregli- Baliköy, 15.V.1976, leg. Besuchet & Löbl ( MHNG, cAss).

Comment. Part of the illustrations (at least Fig. 14 ) in Löbl & Kodada (1996) do not refer to this, but to the following species.

Diagnosis. For a detailed description of external and sexual characters see Smetana (1967) and Löbl & Kodada (1996). The following short diagnosis focuses on characters distinguishing A. schweigeri from the two following microphthalmous species.

Habitus as in Fig. 1 . Head of rather variable relative size, on average larger in males than in females, but sexual dimorphism weakly to moderately pronounced; 1.38–1.45 times as wide as long, even in males distinctly narrower than abdomen, approximately as large as or somewhat larger than pronotum, 0.9–1.1 times as wide as pronotum ( Fig. 2 ); laterally with distinct microreticulation; frons and central dorsal area distinctly more glossy than lateral areas, with or without shallow microsculpture; with or without short shallow median furrow ( Fig. 3 ). Antennomere I approximately 3 times as long as wide ( Figs. 2–3 ). Pronotum 1.2–1.3 times as wide as long ( Fig. 2 ).

ɗ: sternite VII not distinctly modified; sternite VIII with weakly concave posterior margin, on either side of middle with 2 submarginal setae ( Figs. 4–5 ); aedeagus relatively small, from base to apex of paramere approximately 0.5 mm, apices of median lobe rather short ( Fig. 6 ).

Distribution and bionomics. There are confirmed records are from three localities in Bolu and Zonguldak ( Fig. 19 ); Löbl and Kodada (1996) report A. schweigeri also from Kastamonu, but the specific identity of this record must be considered doubtful. The species was collected in oak and beech forests at relatively low altitudes (little above sea level up to 800 m). In the locality in Zonguldak, larvae were found together with the adults ( Löbl & Kodada 1996), which are—at least partly—teneral.
