Melanopsis parreyssi f. scalaris Westerlund, 1886  [invalid]

Original source.

Westerlund 1886: 123.

Type locality.

“Siebenbürgen b. Deva" [Deva], Romania.


Not available from Brot (1879: 431), who listed the name (" Melanopsis scalaris  Parreyss in sched.") as synonym of Melanopsis Parreyssii  var. β, which he introduced there with a short Latin description. Further below on p. 431, Brot even associated scalaris  with an illustration of a specimen from Deva in Romania (pl. 46, fig. 15). However, the name was explicitly referred to as synonym of the (unnamed) variety β, which is not a valid name, and thus the requirements of Art. 11.6 (and therefore Art. 12.1) are not met. Westerlund (1886) was the first to describe it and attributed the authority to Parreyss. It is a junior homonym of Melanopsis scalaris  Gassies, 1856. Neubauer et al. (2014: 125) considered it as a junior synonym of Microcolpia parreyssii  .
