A taxonomic review of the genus Euboeus Boieldieu, 1865 (Coleoptera: Tenebrionidae: Helopini) of the Caucasus, Iran and Turkmenistan Author Nabozhenko, Maxim V. text Zootaxa 2022 2022-07-01 5159 4 451 486 journal article 88477 10.11646/zootaxa.5159.4.1 cffc486a-265f-4d35-a289-a4a54845c77d 1175-5326 6785909 CA6AF6AD-9E4A-4BE3-8B52-6D8E5EA3641F Euboeus ( Pelorinus ) vicinus ( Allard, 1876 ) ( Fig. 6 ) Helops vicinus Allard, 1876: 14 , 34; Helops vicinus : Allard, 1877: 26 , 91; Helops vicinus : Seidlitz, 1895: 706 ; Probaticus ( Pelorinus ) vicinus : Reitter, 1922: 33 , nota 28.; Probaticus ( Pelorinus ) medvedevi Abdurakhmanov et Nabozhenko, 2011 , syn. nov. ; Euboeus ( Pelorinus ) medvedevi : Nabozhenko et al ., 2021b: 441 Type material. Syntypes of Helops vicinus were not found by curators in the Muséum national d’Histoire naturelle Paris. Holotype , ♀ ( ZIN ) of Probaticus medvedevi with labels: Cyrilliс “Арм. ССР Алаверди 25.04.86 Мелях С.В.” ( Armenian SSR , Alaverdi , 25.iv.1986 , leg. S.V. Melyakh ), “ Probaticus ( Pelorinus ) medvedevi Nabozhenko et Abdurakhmanov 2011 ” . Material. 1♂ , 2♀ : “Kaukasus Leder”, “Allard type”, “ Coll. Reitter ”, “ Paratypus 1877 Helops vicinus Allard ” (curator’s label) . Notes. This very rare species was described in 1876 based on the specimen(s) from the collection of Reiche ( Allard 1876 ) and redescribed in 1877 using the type specimen(s) and beetles collected by Leder ( Allard 1877 ). Later, Schneider & Leder (1878) again published Allard’s redescription 1877 and added the species’ type locality: “Elisabetthal”. It was a settlement of German colonists, which is now called Asureti ( Georgia , 41°35′45″N , 44°40′00″E ). Both description and redescription ( Allard 1876 , 1877 ) have differences, and the latter is more consistent with specimens from Georgia and northern Armenia , as mentioned by Abdurakhmanov & Nabozhenko (2011) . In addition, the Russian authors erroneously interpreted species from South Armenia and Nakhchivan as E. vicinus (described below as E. kalashiani sp. nov. ) since Bogachev (1938). As a result, Abdurakhmanov & Nabozhenko described a new species Probaticus medvedevi , from northern Armenia ( Figs 6D, F ). Allard examined the specimens of Leder and confirmed that they belong to his species Helops vicinus , as he wrote in redescription ( Allard 1877 ). The Leder’s specimens ( Figs 6A–C, E, G–K ) are not syntypes (as marked on the labels) because the original description was based on other specimens from the Reiche collection. The females from Georgia are conspecific to the female ( holotype ) of E. medvedevi despite the variability. As a result, I propose the following synonymy: Helops vicinus Allard, 1876 = Probaticus ( Pelorinus ) medvedevi Abdurakhmanov et Nabozhenko, 2011 , syn. nov. Distribution. Southern Georgia , northern area of Armenia .
