7. Labiobaetis Novikova & Kluge, 1987

Diagnosis.

1) Claws hooked with one row of well-developed denticles; 2) second segment of the labial palp with a thumb-like process; 3) paracercus 2/3 of cerci.

Remarks.

All the Maghreb specimens of Labiobaetis were assigned to the Iberian species Labiobaetis neglectus ( Navàs, 1913) (Fig. 4F ). Originally the species was only described at the imaginal stage. The type material is lost, and the original description is very succinct. The specific attribution of the specimens from Algeria to L. neglectus was based on rather obscure criteria ( Soldán and Thomas 1983a). In the same publication, the authors provided the first description of the larval stage based on material from Algeria. Subsequent reports of the species only concerned larvae ( Zrelli et al. 2016; Mabrouki et al. 2017; Samraoui et al. 2021c; El Alami et al. 2022a), and were only based on the characters depicted by Soldán and Thomas (1983a). Examination of larvae from the type locality in Spain is a crucial point to confirm or refute the conspecificity of Maghrebian and Iberian populations.
