5. Cheleocloeon Wuillot & Gillies, 1993

Diagnosis.

1) Claws elongate with two rows of minute denticles; 2) Second segment of the labial palp with a thumb-like process; 3) paracercus subequal to cerci; 4) male with hindwing pads and female without.

Remarks.

The genus Cheleocloeon is mostly diversified in the Afrotropical region and reaches in the Maghreb its north-western limit. Cheleocloeon dimorphicum ( Soldán & Thomas, 1985) is the single species of the genus reported from Maghreb (Fig. 4C, D ). This endemic species is widespread through this area but seems nowhere abundant ( Soldán and Thomas 1985; Boumaiza and Thomas 1995; Mabrouki et al. 2017; El Alami et al. 2022a).
