Atholus ruptistrius Lewis, 1913 and A. conformis (Erichson, 1834)

Lewis (1913: 82) emphasized the “inner lateral [pronotal] stria markedly broken behind the eyes” as distinguishing it from the rest species of the genus. This stria, however, is variable being more or less distinctly interrupted, so it is sometimes difficult to separate A. ruptistrius from A. conformis .

A type examination of both these species enabled to ascertain their identity, especially the genital structure ( Figs. 37-40).

So, Atholus conformis (Erichson, 1834) = A. ruptistrius Lewis, 1913 , syn. nov.

A. conformis has been described on a base of type-series, thus, a designation of the lecto- and paralectotypes are given below.

Lectotype: a male, 1) [green, handwritten] [ RSA]: Pr. b. sp., Krebs, 2) [white, printed] 48945, 3) [red, printed] Type, 4) [green, handwritten] confinis Er. 5) [blue, printed] Hist,-Coll. ( Coleoptera ) Nr 48945, Hister confinis Er. Promont. b. sp., Krebs, Zool. Mus. Berlin, 6) [red, printed] Syntypus, Hister conformis Erichson, 1834 , labeled by MNHUB 2008, 7) [white, printed] Lectotypus, 8) [white, printed] Atholus conformis (Erichson, 1834) Det. S. Mazur 2009 , 9) [white, printed] Des. S. Mazur 2009, [label attached]: The name confinis on the hist. label was obviously confused with conformis described from Cap. [MNHUB].

Paralectotypes: I, sex undetermined, 1) [red, printed] Type, 2) [blue, printed] Hist.-Coll. ( Coleoptera ) Nr 48945, Hister confinis Er., Promont. b. sp., Krebs, Zool. Mus.

Mazur 2009 , II – III: as labeled as the paralectotype I [MNHUB].
