Material examined. 1 ♂ ( Turkmenistan) Krasnowodsk , Transcaspia , Krasnowodsk mys Sarta, e.l. 23.ix.1928, leg. Vlassow (ex coll. Daniel) ( GP 4126 Arnscheid) ; 1 ♂ Israel, Kare Deshe , ix.1966, leg. Kugler (GU 2676 Hättenschwiler 2008) .

Diagnosis. Male wingspan 24–26 mm, Forewing length 12 mm, width 5 mm (11 and 4.5), FI 2.4 to 2.44. Forewings stretched; this species has the most slender wings in the genus, costal margin straight or very slightly concave, apex roundish, termen oblique. All wings translucent, very thinly scaled with triangular or long ovoid scales (class 2–3 after Sauter 1956), more densely along the costal margin. Fringes broad, distal rounded, translucent greyish, glossy, with 4–6 fine dentations (class 5–6 after Sauter 1956). Hindwings with pointed apex and oblique termen, slightly indented in the second half. Scales analogous to forewings, fringes somewhat narrower. Thorax and abdomen densely covered with dark brownish grey hair. Eyes small, roundish, EI 1.2. Antennae of nearly half length of costal margin, 46 segments without pedicellus and scapus. Pecten short, 0.3 mm (0.85 mm).

Male genitalia. (GP Arnscheid 4126) Elongate in general appearance, tegumen distinctly indented distally, slightly folded laterally and distally, covered with short hair. Valvae short, not extending beyond the distal end of tegumen, roundish apically and covered with short setae. Clasper of sacculus elongate, slender, narrower distally and covered with short spines apically. Anellus short, pointed. Vinculum weak trapezoid. Saccus long, stretched and distinctly pointed. Phallus of genitalia length or longer, slightly bent, with distinct roundish enlargement caudally, vesica with short cornuti.

Distribution. The type locality of A. quadrangularis is Iran. We found two further specimen in the MWM from Turkmenistan and Israel. This shows a larger geographic range that should be cleared in future studies and based on larger set of material.
