Diagnosis. Malar keel prominent and angular, hypostomal ridge raised, surrounding distinct postmalar area; longitudinal keel present between antennal toruli; antennae in female short, with subquadrate flagellomeres; flagellomeres in males cylindrical with flagellomere 1 moderately emarginate; radial cell short; mandibles strongly sickle-shaped and widely overlapping; pronotal shoulders not edged; front tibae in males with a row of long stiff bristles.

Variability. No significant variation was observed in the limited material available.

Differential diagnosis. This species is unusual in having a well-developed postmalar area margined by a strong malar keel, a prominent hypostomal ridge, and a longitudinal keel between toruli (unique for Aclista ). The species is easily distinguished from other species of the A. scutellaris species complex by the longitudinal keel between toruli and the very short radial cell.

Distribution. Czech Republic ( MACEK 1989), England ( NIXON 1957, WALL 1967), Finland ( WALL 1967), Scotland ( WALL 1967), Sweden ( NIXON 1957, WALL 1967), Switzerland ( WALL 1967). New records: Austria, Germany, Hungary and Slovakia.

Remark. The identification of the species is based on NIXON’ s (1957) key diagnosis.
