The species is distributed in the Eastern Alps, extend- ing northward to the Vosges and the Eastern Sudetes, the Carpathians, known from the Dinaric Mountains southward to the Rhodopes ( Fig. 3 A ). The range of O. norici roughly encircles the Great Hungarian Plain. It is also known from Drava River Valley. An isolated population occurs in the Mecsek Mountains. Amphigonic populations occur in the Eastern Alps and the Drava Valley. The males are unknown in the Balkans ( Angelov 1976) and the Ukrainian Carpathians. The species is protected in Bavaria ( Sprick et al. 2003); Knutelski & Tykarski (2010) noted that O. norici is vulnerable in Poland.

In the Ukrainian Carpathians O. norici was known from Kuzy ( Roubal 1941) and vicinity of Lake Synevyr ( Nazarenko & Parkhomenko 2016).

Ecology. The first author collected O. norici on Petasites hybridus (L.) G.Gaertn., B.Mey. & Scherb. along mountain streams ( Fig. 4 С); beetles hide underneath the foliage during the day. In Scharfling ( Austria) some specimens were found by Teodor & Milin (2014) swept a single specimen in a spruce forest from Rumex and Urtica in the South Carpathians.

Nomenclature notes. As recently discussed by Colonnelli (2024), Alonso-Zarazaga (in Magnano & Alonso-Zarazaga 2013) introduced the replacement name of Otiorhynchus norici for O. austriacus (Fabricius, 1801) , described as Curculio Linnaeus, 1758 and thus primary homonym of Curculio austriacus Schrank, 1781 . Among the synonyms of this species of Otiorhynchus are listed two other names, namely O. carinatus Gyllenhal, 1834 and O. costatus Stierlin, 1861 , both homonyms. However, a replacement name had already been given to O. carinatus Gyllenhal by Csiki (1943), as O. austriacus ab. carinatostriatus . The alternative use for this taxon of the specific epithet norici Alonso-Zarazaga, 2013 or carinatostriatus Csiki, 1943 has been the subject of debate during a recent meeting of some ICZN’s members. They acknowledge the complexity of the case due to potential dual interpretations of Articles 45.5 and 45.6 of the ICZN ( International Commission on Zoological Nomenclature 1999), but all final- ly agreed that the name O. carinatostriatus Csiki, 1943 is unavailable (because originally explicitly introduced as an infrasubspecific name). Waiting for a formal decision of the ICZN, we therefore decided to use herein the name Otiorhynchus norici , following Magnano & Alonso-Zarazaga (2013) and Alonso-Zarazaga et al. (2023).
