Pseudorthocladius (Pseudorthocladius) berthelemyi Moubayed, 1990

Material examined.

11 pupal exuvia, Rika River (S 6), 7 May 2018 .

Distribution.

Palaearctic. Austria, Bulgaria, Corsica, France, Germany, Portugal, Slovakia, Spain, Turkey, and Morocco ( Ashe and O’Connor 2012).

Habitat.

Mountain streams and rivers with stony bottoms. The species is rheophilic, cold-stenothermal with high demand for dissolved oxygen ( Martínez et al 1995; Moubayed-Breil et al. 2012). It can also inhabit hygropetric sites ( Moubayed-Breil 2008).

Remarks.

The species is considered a Mediterranean element ( Moubayed-Breil 2008) with an originally circum-mediterranean distribution ( Laville and Langton 2002). The extra-Mediterranean occurrence in more northerly countries indicates its relict character (see comments to Cricotopus beckeri ).
