Segment IX fused with basal parts of inferior appendages, with narrow acuminate dorsal portion and longer ventral portion, laterally even longer, convex anteriorly, in lateral view. Superior appendages apically bipartite with round ends in lateral view. Intermediate appendages wide basally, tapering apically, downward arching in lateral view. Free parts of inferior appendages broad, triangular, acute apically, each with posterior edge notched basally in lateral view. Inner lobe of free part of each inferior appendage visible in lateral view as small subapical triangle; in ventral view broadly quadratic, blunt dorsoapically, elongate, acute ventroapically. Phallic apparatus consisting of simple aedeagus and pair of parameres; in ventral view parameres broader basally, acute apices as high as tip of aedeagus.
. Segment IX setation abundant, more abundant in the dorsal half and along the lateral margins. Segment X triangular in lateral view, blunt apically in dorsal view; in ventral view wide along basal half and parallelsided apically. Supragenital plate apically round in lateral view, shorter than segment X; vulvar scale even shorter, elongate, subtriangular. Lateral shoulders of segment IX membranous, with sclerotized edges, long ventrally, short dorsally, generally triangular, turned mesad posteriorly.

The new species was found in one of the permanent tributaries of the Isly River (south of Oujda City), in a location known as Tayret. The river exhibits irregular flow patterns closely tied to rainfall, experiencing floods from autumn to spring and severe summer low flows nearly year-round. The intense sunlight fosters the growth of perilithon, filamentous algae, and green algae (
). The sediment in the springs consists of blocks, stones, pebbles, sand, and occasionally mud. The vegetation along the banks is sparse, predominantly comprising reeds (
