Types examined: The type of Tentyria mucronata Steven was not found between the types of Tentyria (MNHUB). We found a specimen bearing an old label written with “Gallia” and conserved in the Scĥnherr´s collection (NRMS) and seven syntypes: Tentyria nitida /in coll. Solier Coll. de Marseul (MNHN).
One specimen labelled as syntype of Tentyria oblonga in coll. Solier Coll. of Marseul (MNHN), bearing five labels: Tentyria mucronata oblonga Sol, T, Espagne, col DU 64/Type Solier/MUSEUM PARIS, Coll. Solier, Coll. DE MARSEUL, 2842 90 / SYNTYPE / Tentyria oblonga Type Solier.
Two syntypes of Tentyria elongata Waltl, carrying the label “ Hispania / Tentyria elongata Waltl ” (NHMW).
Additional Material: Tentyria oblonga Sol, Korb. Elias, Cuya 66/MUSEUM PARIS, Coll. Solier, Coll. DE MARSEUL, 2842-90. France, Camargue: Camarful, Arlés, P. Bonat Leg.

Diagnosis: According to the original description “The body is black, slightly shiny, oblong, ovate and convex. Pronotum with the central lobe bi-mucronate. France meridional” (translated from Latin). Mulsant (1854) provided a very detailed description of this taxon.
Body oval, elongate (Fig. 186). Head (Fig. 1) with eyes slightly convex and temples converging backwards, supraorbital fold thick; epistome with the anterior margin rounded, or very slightly angled, provide with a small tooth in the middle; gular groove slightly transverse and somewhat deep (Fig. 36). Pronotum (Fig. 70) with maximum width after the middle, sides rounded, somewhat narrower towards the base than at the apex; base strongly sinuate before the rear angles and with the median part prolonged backwards in a lobe, usually bi-mucronate or truncate, and often not bordered at the middle; punctures well marked, somewhat smaller than in the head; some specimens have on disc two pit-like impressions on both sides of the midline. Prosternal apophyses (Fig. 106) parallel-sided and somewhat longitudinally furrowed, with rounded or ogival end. Elytra oval, elongate, with maximum width before the middle and tapering regularly towards apex; base of elytra completely bordered, and medially curved around scutellum (Fig. 144); sculpture of elytra very variable, slightly striated, rugous, or smooth, but always with punctures somewhat finer than that of pronotum. Aedeagus (Fig. 154) about 3.7 mm long, parameres with sinuous sides, slightly longer than phallobase, and with truncate apex, neither spiniform, nor denticulate.
Comments: Solier (1835) described T. oblonga from Barcelona and T. nitida from an uncertain locality, as a very close species to T. mucronata Steven, even considering that they could be varieties of this taxon. Kraatz (1865), and all the subsequent authors, include these species within the specific group of T. mucronata Steven, considering that the differential characters mentioned by Solier (1835) are the result of the specific variability. Indeed, within the same population we find individuals that differ in size, thickness of the body, development of the central lobe the pronotum, from just clearly bi-mucronate to not mucronate and / or truncated; the sculpture of the elytra, from smooth to clearly striated and / or rough, the punctures more or less marked on the surface of the body, ..., differences more related to sexual dimorphism (such as more slender and elongated body in males) than a specific separation.
On the other hand, in the NHMW can be found two syntypes of T. elongata Waltl (Fig. 222), a primary homonym of T. elongata Gebler (= Anatolica angustata (Steven, 1828)). These specimens are identical to those of T. mucronata Steven, a french-catalonian species. This concern has caused a great confusion in the taxonomy of the iberian Tentyria.
Geographical distribution: Described from southern France and extended in the French and Catalan Mediterranean coasts, northern of the Ebro River (Español, 1960).
