MATERIAL EXAMINED. 2♂, 2♀, Morocco: Fahs-Anjra , Rmel, 15.II.2020, 35°38´57.4´´N, 5°35´41.4´´W, 372 m., M. Nourti leg. GoogleMaps

HABITAT. Represents a scrubland with rocky soil of a clay-calcareous nature crossed by a small stream and bordered by vegetation mainly composed of Pistacia lentiscus L., Carlina racemosa L., Conyza conodensis L., Erica arborea L., and Cistus monspeliensis L. Further afield, fruit trees grow, such as Olea europea L. and Ficus carica L. ( Figs 10–11 View Figs 10–11 ).

NOTES. First record of the species from Morocco. S. parvula was reported previously from France and Spain. See also remarks under S. parvilamellata .

DIAGNOSIS. S. parvula and S. parvilamellata are close to S. lorifera , differing from the latter in non-thickened antennal stylus and relatively short apicoventral epandrial lobe. S. parvula differs from S. parvilamellata in antennal stylus with basal segment distinctly longer than apical segment; cercus straight, black, with equally short setae; phallus narrowed distally.
