( Figs 1 , 2A, B ) = Helopelius disgregus ( Reitter, 1922 ) , syn. n. = Stenohelops ( Stenomaleis ) gayirbegi ( Nabozhenko & Keskin, 2009 ) , syn. n. Type material. The lectotype ( ♀ ) of Stenomax aeneipennis Allard, 1876 is designated here, deposited in NHML ( Figs 1A, B ). Allard (1876 , 1877 ) didn’t indicate how many specimens are in the type series. The lectotype is designated according to the articles 61.1 and 74.1 of ICZN (1999) : “ Hedyphanes aeneipennis . Mill. Rhodes. (V. Schaufuss)—”, “ Stenomax aeneipennis V all: Mill:”, “ Stenomax aeneipennis ” (handwritten label of Allard), “F. Bates Coll. 81—19.”, “ Helopelius aeneipennis , All. ”, label with QR-code and number “NHMUK 014380366”. The lectotype (♂) of Cylindrinotus ( Helopelius ) disgregus Reitter, 1922 is designated here, deposited in NHMB ( Figs 1 E–H). Reitter (1922) indicated that the species is deposited in the collection of A. Schuster under the name “ gratus ”, but didn’t indicate how many specimens are in the type series. The lectotype is designated according to the articles 61.1, 74.1 of ICZN (1999) : “TYPUS”, “Rhodus”, “ gratus ”, “Winkler”, “ disgregus Rtt det.” (handwritten label of A. Schuster). The holotype and paralectotypes of Gunarus gayirbegi Keskin & Nabozhenko, 2009 are designated in the original description, as well as figures and photos (Keskin & Nabozhenko, 2009 ). Other studied material: 1♂ ( CMN ): Greece , Dodecanese , Rhodes , Koskinou , N 36°22′56″ , E 28°12′56″ , 29.iii.2020 (leg. K. Kalaentzis ) ( Fig. 2A ); 1♀ from Attaviros Mt. ( Emponas ), Rhodes was examined alive, photographed and released ( Fig. 2B ); 1 ♂ ( NHML ): “ Hedyphanes Aeneipennis Mill. Rhodes ”, “ Pascoe Coll. 93—60”, label with QR-code and number “ NHMUK 011520988 ” ( Figs. 1C, D ); 1♂ , 1♀ ( CMN ): Turkey , Denizli Prov. , Turkey , Babadağ Distr. , Akdağ ridge , N 37°47′740″ / E 28°48′493″ , 1425–1500 m , 6.05.2009 (leg. M.V. & S.V. Nabozhenko , B. Keskin ); 20♂ , 25♀ ( CMN ): Turkey , Isparta Prov. , Davraz Dağı , N 37°47′827″ / E 30°45′505″ , 1603–1650 m , 11.05.2009 (leg. M.V. & S.V. Nabozhenko , B. Keskin ) . Notes. We compared specimens from Rhodes and Turkey and found that the structure of male protarsi, male apical antennomere and aedeagus are identical in all populations of S. aeneipennis . The following characters can be variable even within one population: elytral shape, convexity of elytral interstriae and the degree of expression of elytral tubercles with coeloconic sensillae. Distribution. The species is distributed in West Turkey ( Denizli , Isparta , Mugla and Antalya provinces) and Greece (Rhodes Island). Maxwell Barclay and Keita Matsumoto also sent us photograph of one female with labels “ Syria de Brulerie”, “ aeneipennis ”, “Sharp Coll. 1905-313” (NHML). This specimen is very similar to S. aeneipennis but additional material from Syria is necessary to examine; the geographic label is possibly erroneous and we cannot yet confirm the record of this or other species in Syria .
