Diagnosis : Elongated body ( Fig. 191 ), 2.37 times longer than broad on average; size 14.4 mm long and 6.1 mm broad on average. Head ( Fig. 6 ) subparallel sided, with the anterior edge of the epistome truncated; the gular groove ( Fig. 41 ) consisting of a shallow depression. Pronotum ( Fig. 74 ) with fine and sparse punctures, finer than in head; transverse, at least in males, 1.28 times broader than long on average; the maximum at the middle ( 4.23 mm broad and 3.29 length on average); posterior angles well noticeable, straight, or slightly obtuse; base completely margined and clearly tri-sinuate; prosternal apophysis ( Fig. 111 ) elongated, longitudinally furrowed, subparallel-sided and sharply tapering towards the apex that which, usually, is protruding between the procoxae; the apex feebly down curved. Oval elytra, tapering in a straight line near the apex; base in open arc, the basal margin deleted, only visible it the humeri which are angulate and with unnoticeable punctures ( Fig. 142 ); disc provided with punctures inconspicuous and more or less striated, but always with superficial striae and broad intervals, never costiform, with irregular transversal rugosities; on average, 2.74 times longer than pronotum, 1.49 times longer than broad; anal urosternite truncate at the end ( Fig. 149 ); aedeagus ( Fig. 159 ) large and slender, 3.7–4.2 mm long ( 3.95 mm on average), the parameres and the phallobase of same size. Females, generally, broader, with the protibia shorter and right in the inner side. Comments: T. sinuatocollis has been confounded since its description with other taxa. In fact, Rosenhauer (1856) described T. sinuatocollis from three different taxa, considering two of them as variable forms of the same taxon: T. sinuatocollis Rosenhauer ( T. arenaria Rambur in litt. Fig. 249 ), T. emarginata Kraatz ( T. emarginata Rambur in litt. Fig. 250 ) ( = T. subcostata Solier ) and T. striatorugosa sp. nov. ( T. rugosostriata Rambur in litt. Fig. 251 ). Rosenhauer (1856) described this species characterized by having small head, with epistome short and truncated. Pronotum barely convex and not very transverse, with very fine punctures, curved sides, and slightly narrowed before base, which is broad, tri-sinuate, and finely margined, with the posterior angles slightly protruding and acute. Oval elytra, narrowed to the apex, slightly convex and depressed in the suture, sub-striate, and with transverse rugosities. Rosenhauer himself, remarked that some specimens show the elytra inconspicuously striate or rough, and the base of pronotum non entirely margined at middle. Kraatz (1865) , erroneously consider Tentyria sinuatocollis Rosenhauer a variety non-distinguishable of T. elongata Waltl (= Tentyria mucronata Steven ), species obviously ignored by Kraatz (1865) , as it could be verified if the diagnoses of both authors are compared ( Waltl 1835 ); being in turn Tentyria elongata sensu Kraatz (1865) a copy of the diagnosis of Tentyria sinuatocollis Rosenhauer (1856) . Moreover, Kraatz (1865) located Tentyria elongata Waltl in the Southeast of Andalusia and stablished three geografic varieties only differentiated in the elytral sculpture. All following authors ( Reitter (1900) , Koch (1944a) , Español (1960) , Viñolas (1986) , Viñolas (1991) , Palmer (1998) , Viñolas & Cartagena (2005)) repeated the error of Kraatz (1865) considering T. elongata Waltl as a valid species distributed in the Southeast of the Iberian Peninsula, thus misinterpreting the true identity of Tentyria sinuatocollis Rosenhauer. Since Koch (1944a) to nowadays, this species has been identified with the variable specimens described by Rosenhauer, with the rough-striated elytra, the basal lobe of pronotum unmargined and the posterior angles obtuse ( = T. striatorugosa sp. nov. ). Finally, T. sinuatocollis has been wrongly transcribed “ sinuaticollis ” by Español (1960) , Viñolas (1986 and 1991 ), Palmer (1998) and Viñolas & Cartagena (2005) . Designation of the Lectotype of Tentyria sinuatocollis Rosenhauer, 1856 , present designation: To stabilize the taxonomy of the genus we designate Lectotype the unique specimen we have located from the Rosenhauer’s collection (Rsh. 69) via coll. Solier and labelled as type (T). Hereby we designate Lectotype of Tentyria sinuatocollis Rosenhauer, 1856 the specimen carrying the labels: Tentyria sinuaticollis And., Rsh. 69, T / 357 / MUSÉUM PARIS, COLL. DE MARSEUL 1890 / MUSÉUM PARIS, COLL. SOLIER, 9641-34 / v. sinuaticollis-Rosh . / Tentyria sinuaticollis , Andalusia (MNHN) ( Fig. 227 ). Geographical distribution: Mediterranean littoral of the Iberian Peninsula, from the Southeast of the province of Cádiz to Almeria, more frequent in the province of Málaga; the record from “Sevilla” in MNCN without collector data is doubtful and need to be confirmed.
