Kahlen kindly communicated that the locality "Amraser Au" was once a real "beetle paradise", a river pasture on the left side of the river Inn , east of Innsbruck , in Austria ; altitude 565 m , co-ordinates ca. 47.16N 11.26E . Today this locality has been totally destroyed by a highway, a sewage plant, industrial factories, etc. 1, 3, "Welsberg, Ti. [= Tirol ], Ganglbauer" [printed], the male with additional " R.

Descriptive notes : H. discretus ab. woerndlei is a taxon of infrasubspecific rank (cf. article 45.6.2 of the ICZN). The specimens studied have an oval elongate and vaulted habitus which equals that of H. discretus discretus from e. g. France and Germany . Mature specimens have dark brownish elytra, and a black pronotum with its lateral beading sometimes brownish. The base of the elytra is light brown, and some specimens have a rather distinct yellowish brown spot on the shoulders. The aedeagus is similar to that of H. discretus from other regions. Measurements : TL: 3.0– 3.35 mm , MW: 1.6–1.75 mm ; TL/MW: 1.82–1.94.
