Treatment

MATERIAL EXAMINED. — Corsica. F 35, 1 ♂ ; F 79, 1 ♀; F 83b, 1 ♂, 1 ♀; F 84, 1 ♂, 1 ♀. Sardinia. I 1155, 1 ♂; I 1159, 1 ♀; I 1160, 1 ♂; I 1162, 1 ♂ ( MNHN) .

Corsica. F 79, 2 ♀♀ ; F 83b, 4 ♀♀; F 84, 2 ♀♀, 2 ♂♂.

Sardinia. I 1172, 1 ♂ (Coll. RG).

DISTRIBUTION. — West Palaearctic. Central and Southern Europe, Turkey, few ascertained records probably due to previous confusion with A. distans (K. Viets, 1914) . First records from the area covered; new for Italy.

HABITAT. — Rhithrobiont, in Corsica crenophilous. Nearly exclusively in springs, often at high altitude, in the area covered from 250 to 1400 m.

REMARKS

This species, confused over long time with A. distans (see Gerecke 2003), has been recently discovered in many parts of the Western Palaearctic. Some specimens from Corsica and Sardinia combine rather large glandularia with extended coxal borders of secondary sclerotization. In these cases, also Vgl-1+2 which are typically separate in this species may fuse, but the origin from two separate platelets remains always visible due to an irregular indented border line.
