Here, we propose its integration into the genus Soulierana Bucher & Bouteille gen. nov. with the description of the male genitalia for the first time.TOTAL LENGTH. Between 5.2 and 5.5 mm.HEAD. Median part of vertex relatively flat, forming very obtuse angle with postclypeus. Median furrow on postclypeus wide, deep, beginning below front margin of head and straight at upper extremity. Lateral bulges very thin and comparable to two carinae, parallel and keeping same width over entire length; in dorsal view, postclypeus slightly exceeding anterior margin of head; in lateral view, postclypeus convex and forming obtuse angle slightly pronounced.THORAX. Scutellum relatively flat.TEGMINA. Three bumps clearly distinguishable on each tegmen. Apical network not dense with fewer than 15 concave cells per tegmen.MALE GENITALIA. Subgenital plates longer than length of pygofer, margin wider on first third and curved dorsally on apical third; on apical margin, flattened internal part covered with setae forming rounded protuberance. Sterno-lateral plates greatly exceeding posterior margin of pygofer. Parameres inserted almost entirely in pygofer and not very visible in lateral view, their dorsal margin bearing dorsal extension, posterior tip forming spine hook-shaped clearly visible in dorsal view. Aedeagus developed anteriorly in one-pointed protrusions; ventral margin forming convex arc and going straight up linearly towards dorsal part. Aedeagus bifid on its apical part; posterior extension with thin serrated apex, on last third; anterior dorsal extension with rounded apex representing one third length of posterior one.COLORATION. Specimens entirely black except for thorax ochre-yellow in ventral view.
