O. halimeae sp. n. is only the second species of the subgenus with distinctly raised elytral vestiture. It differs from Otiorhynchus trichopterus Białooki, 2015 in disparate female terminalia (male of O. halimeae unknown); raised elytral scales strikingly shorter and much less protruding; distinctly smaller body; pronotal disc covered with fat but nevertheless well-developed tubercles; elytral declivity distinctly overhanging; and lack of elytral recumbent broad scales. Key words: Coleoptera, taxonomy, new species, Otiorhynchus, Turkey. INTRODUCTION The subgenus Pterygodontus Białooki, 2015 until now comprised seven species (alonso-ZaraZaGa et al., 2017) previously placed in the subgenus Podonebistus reitter, 1912. The majority of them occur in Turkey. All are dendrophilous species living in forest zone at low and moderate altitudes. Recently another species of this group was discovered in Turkey which is described below. MATERIAL AND METHODS This new species was discovered on 21.04.2022 in Kahramanmaraş Province, Onikisubat/Demrek neighborhood. The single specimen was detected in the root part of Helleborus vesicarius aucher ex Boiss. The width of the rostrum is defned as the pterygial span, i.e. the distance between the outer margins of pterygia. “Pterygia projecting” means
