Rhithrogena undetermined Sowa 1984

Rhithrogena sp. hybrida group (sensu Sowa 1984) TAXO-2022. This taxon corresponds to one morphotype belonging to the hybrida group, identified by larval and nymphal (ovocytes) stages (Fig. 2 A). Larvae and ovocytes were close to R. degrangei Sowa, 1969, but they do not meet all the identification criteria: differences in shape and number of bristles of surface of femora, tergal coloration, comb-shaped bristles of the lacinia and chorion eggs surface. We have therefore considered it to be a probable different undescribed species, which was also confirmed by our molecular data (PP 387919 to PP 387924), which places the species in a different clade compared to the other referenced species from the hybrida group.

Abstract

Rhithrogena sp. hybrida group (sensu Sowa 1984) TAXO-2022. This taxon corresponds to one morphotype belonging to the hybrida group, identified by larval and nymphal (ovocytes) stages (Fig. 2 A). Larvae and ovocytes were close to R. degrangei Sowa, 1969, but they do not meet all the identification criteria: differences in shape and number of bristles of surface of femora, tergal coloration, comb-shaped bristles of the lacinia and chorion eggs surface. We have therefore considered it to be a probable different undescribed species, which was also confirmed by our molecular data (PP 387919 to PP 387924), which places the species in a different clade compared to the other referenced species from the hybrida group.
