Description of Ecdyonurus solus sp. nov., a new species of the Ecdyonurus venosus species-group (Ephemeroptera: Heptageniidae) from the Crimean Peninsula, Ukraine

Abstract

The larvae and adults of Ecdyonurus solus sp. nov., are described and illustrated. This species is found in the mountainous region of the Crimean Peninsula, and belongs to the Ecdyonurus venosus species-group. SEM photographs of the eggs of new species are presented. The distinguishing characteristics separating this E. solus sp. nov. from closely related species of the E. venosus species-group are discussed. Detailed data on the biology and distribution of the new species are presented.

Type material comparison of possible cryptic species of the genus Electrogena (Ephemeroptera, Heptageniidae) in Central Europe

“…Nevertheless, in several other works (e.g. Landa and Soldán 1989; Deván 1989; Kłonowska-Olejnik 2003), E.samalorum has been indicated as a separate species, although its larvae (e.g. in Deván 1993) were compared with larvae of the species E.lateralis , but not of E.ujhelyii. In addition to the absence of a detailed material comparison, there is another detail that brings into question the synonymy of both species.…”

New Records of Some Rare Mayflies (Insecta, Ephemeroptera) From Ukraine

“…By now there are 113 mayfly species in the national species list (Zakharenko 1955;Godunko & Kłonowska-Olejnik 2003Godunko et al 2004a, b;Kovács 2006;Kłonowska-Olejnik et al 2007;Martynov 2010Martynov , 2011Martynov , 2013Martynov & Godunko 2010, 2013. However, the records on some species from Ukraine need confirmation because of absence of the detailed data on the sampling places or high possibility of incorrect identification (see Godunko & Kłonowska-Olejnik 2003 for details).…”
