Novitsky RA, Son MO. 2016. The first records of Marmorkrebs [Procambarus fallax (Hagen, 1870) f. virginalis] (Crustacea, Decapoda, Cambaridae) in Ukraine. Ecologica Montenegrina 5: 44-46. http://www.biotaxa.org/em/article/view/19706/19060

Abstract

Without abstract. Excerpt:

During last decades expansions of three invasive alien decapods (Rhithropanopeus harrisii , Eriocheir sinensis Milne-Edwards, 1853 and Macrobrachium nipponense (De Haan, 1849)) have been reported from Ukrainian inland waters (Son et al. 2013).

In 2015 two localities of a new alien species – Marmorkrebs or marbled crayfish Procambarus fallax (Hagen, 1870) f. virginalis were observed (Fig. 1).

Keywords: None provided.

Mystery cameo

Marmorkrebs makes a brief cameo appearance in a new paper about that evergreen biological topic, species concepts:

More recently MARTIN et al. (2010), discussing the way parthenogenetic population derives from bisexual species (the concrete case of Cambarus fallax, the so-called Marble crayfish), considered that for such uniparental populations the phylogenetic species concept should apply, because parthenogenesis is an apomorphic trait within a given phylogenetic lineage with bisexual ancestors.

What surprising to me is the species name. They are not the first authors to omit the “forma virginalis”, but I think they are the first to put Marmorkrebs in the genus “Cambarus.” This is puzzling since they cite the paper that clearly says Marmorkrebs are “Procambarus.”

Mysteries of editing.
