Mylabris schreibersi ab. unifasciatella Kaszab, 1958b: 190.

Type locality. “ Alger, Bône, Oran ” ( Chevrolat, 1840). All these localities are positioned along the northern Algerian coasts. Actually, the name M. schreibersi was proposed by Reiche (1866) to substitute that of M. terminata Chervolat, 1840 , preoccupied by the homonym species described by Illiger. Reiche (1866) recorded M. schreibersi from Sicily.

Type material. Types of both Chevrolat and Reiche are missing at MNHN. Being the definition of the species clear, according to the ICZN, we prefer do not designate a neotype.

Description. Body length: 10–20 mm; setae uniformly black, but mixed golden and black on legs; antennomeres uniformly black, III ca. 1.5 times as long as IV, XI ca. twice as long as wide ( Fig. 25 A); pronotum without fore transverse depression; elytra black pattern ( Fig. 25 B) with four (2:2) spots, apical black fascia very narrow and not extended laterally; mesosternum as in Fig. 25 C; male gonoforceps relatively wide in lateral view ( Fig. 25 E), fused ventrally in basal third ( Fig. 25 D); distal hook of aedeagus slightly far from apex and similar in size to the proximal one ( Fig. 25 F).

Taxonomic remarks. The length of mesosternal apex is variable: It is slender in Sicilian populations and relatively short in the Moroccan and Algerian populations; in Tunisian populations, the length varies between the two conditions.

Distribution. N Morocco, N Algeria, N Tunisia, Sicily ( Italy).
