Tentyria interrupta var. heydeni sensu Gebien 1910: 70 . Tentyria curculionoides ssp. curculionoides sensu Koch 1944a: 229 . Types examined: Seven syntypes from Aveiro , Portugal ( Gaedike 1986: 385 ), (ZSM). We have examined two of them bearing the following labels: Aveiro , Heyd. / Heydeni Haag / Sammlung, Haag-Rutenberg / red label: Holotypus , Tentyria heydeni Haag, Staatssamml. München / blue label: Zool. Staatsslg. München / heydeni Haag. ((1♁, ZSM) (Fig: 230, a, b). Paratypus : ( 1♀ , ZSM) carrying similar labels than the type ( Fig. 230c ).

Julio Ferrer 1987 / Tentyria heydeni Haag. Det. J.L. Bujalance (2 ♁♁, CJF ? NRMS ?). In the MNHN there are specimens caming from the following portuguese localities: São Marthino do Porto , São Pedro de Moel, Praia de Vagos prés de Aveiro , Praia do Pedrogão, Praia de Afife (Viana Castello). Diagnosis: According to the original description, Tentyria heydeni Haag-Rutenberg , is a species close to Tentyria curculionoides (Herbst) , sharing the configuration of pronotum, but differing in the overall shape, slenderer ( Fig. 197 ). The head ( Fig. 11 ) is more strongly punctured than the rest of the body, with a rounded depression in the front, between the eyes; without epistomal tooth and with graceful antennae. Gular groove ( Fig. 46 ) slightly marked, drawing a sunken “V” in the middle; ventral side of the head strongly punctured. The pronotum ( Fig. 80 ) 1/3 broader than long, with sides more narrowed towards the base than in the apex, somewhat sinuous before the posterior angles that are rather drooping and well-marked; the base curved and slightly sinuate on the sides; with thick margin, the disc is slightly convex, bright, and finely punctured. Elytra oblong, ovoid and without wrinkles, barely depressed, base provided with a thin and shiny carina, sometimes erased before the scutellum; in some specimens there are vestiges of apical striae. In addition, the prosternal apophysis sub-parallel sided ( Fig. 116 ), ending rounded and slightly depressed in the middle. Differential diagnosis : Tentyria heydeni Haag-Rutenberg , has been confused with Tentyria curculionoides (Herbst) and with Tentyria interrupta Latreille. It is distinguishable from T. c urculionoides by the more prominent supraorbital keel; the space between the eye and the keel is not or barely visible in dorsal view; the pronotum with the sides more convergent towards the base and usually somewhat sinuate before the posterior angles, which are better indicated; the base often sinuously curved before the posterior angles; more graceful protibiae in males; the elytra commonly in more elongated oval, smooth or with marks of grooves, never rough-striated; and at least, as punctured as the pronotum; frequently with the basal margin interrupted before the scutellum; and, finally, by the aedeagus ( Fig. 164 ) with the penis non enlarged in the anterior middle, and the parameres with subparallel sides and longer than the phallobase. It differs from T. interrupta , by the most prominent and not sinuous supraorbital keel, the epistome less elongated, pronotum of sides narrower towards the base and generally somewhat sinuate before the posterior angles that are better marked; elytra wider than in T. interrupta which has the elytra proportionally more elongated, very finely punctured, with signs of striation and with more rounded humeri; and, finally, by the aedeagus, with the parameres longer and greater ratio parameres/phallobase in T. heydeni . Comments : The confusion about this taxon is reflected in literature: In the Gebien’s catalogue (1910) the species is cited as a variety of T. interrupta Latreille ; Koch (1944a) did not mention this species and confused it with T. curculionoides (Herbst) . This species was also unknown to Español (1956) , who considered it a subspecies of T. interrupta Latreille, Español (1960) , suggested that T. heydeni Haag-Rutenberg and T. interrupta Latreille must be included in the same group of species than T. curculionoides (sensu Koch) . Finally, Viñolas & Cartagena (2005) , established the synonymy of Tentyria heydeni Haag-Rutenberg and T. interrupta Latreille. Geographical distribution: Species known in the portuguese coast, from Peniche to Afife.
