Type material. Lectotype of Helops corrugosus Seidlitz, 1895 ( SNSD), designated here according to Article 61.1 and 74.1 of ICZN (1999), with labels: bronze square, “ subrugosus tut Allard”, “ ♂ astrabad Christoph”, “13916”, “ Helops corrugatus Seidl. ” [handwritten by G. Seidlitz], “ corrugosus Seid. nec corrugatus det.Schuster”. The label “ Helops corrugosus Seidlitz, 1895 des. M. Nabozhenko 2021” was added to the lectotype.

Holotype of Probaticus parthorum (ZIN) , ♂ with the Cyrillic Russian handwritten label “Астрабад, Сев. Иран 9–12.V.1912 Билькевич” (Astrabad, North Iran, leg. Bil’kevich), “ Holotypus Probathicus (Pelorinus) parthorum G. Medvedev, 1977 ” . Paratypes. 1♂ with labels: “Астрабад С. Персия [print] 6.III.904 [handwritten] Филиппович [print italic]” ( Cyrillic , Russian: Astrabad, N Persia, leg. Philippovich) and “ Paratypus Probathicus (Pelorinus) parthorum G. Medvedev, 1977 ” ; 1♂: the same labels, but 18.II.1904; 1♂: the same labels, but 5.V.[19]04; 1♀: the same labels, but 23–24.IV.[1]905; 1♀: the same labels, but 29.V.[19]04 and additional labels “ Probaticus sp. aff. 4-collis Bdi Dr Z. Kaszab det., 1960”, “ Probaticus sp. ” Red labels with “ Holotypus ” and “ Paratypus ” were pinned by a laboratory assistant (A.K. Chistaykova) with erroneous year and the name of the genus.

Material. 1♂, 1♀ ( HNHM): “Persia Astrabad 5.99 Coll. Hauser ” ( Iran, Golestan Prov., Gorgan, v.1899) ; 1♂ ( SMNS): Iran, Golestan Prov., Karim Ishan , 70 km NE Gonbad-e-Kavus, 4– 7.04.1999 (leg. J. Rejsek) ; 2♂, 1♀ ( SMNS): Iran, Golestan Prov., 10 km S Bandar e Gaz , 27.05– 7.06.2001 (leg. G. Sama) .

Notes. This species was described from two males from “Klein-Asien” and “Astrabad” ( Seidlitz, 1895, p. 707) in the key. Leo and Ruzzante (2016) mentioned that it is a “mysterious” species, described from these two different localities. Sahlberg (1913), Reitter (1922) and Nabozhenko and Löbl (2008) mentioned different species from the Aegean region. Nabozhenko (2020 b) listed E. corrugosus for Greece, Turkey and Iran. One syntype (male) from “ Asia Minor ” was originally mentioned from the collection of G. Kraatz, but it was not found in the Senckenberg Deutsche Entomologische Institut (Müncheberg, Germany). I studied the second Iranian specimen (designated here as the lectotype) ( Fig. 1 ), which is conspecific to Medvedev’s E. parthorum ( Fig. 2 ) also described from Astrabad. Thus, the following new synonymy is proposed: Helops corrugosus Seidlitz, 1895 = Probaticus parthorum G. Medvedev, 1976 , syn. nov.

Distribution. Iran (Golestan Province).
