Description: Holotype (Fig. 196), usually round body, with smooth, black, and shiny tegument. Size: 13.6 mm long and 6.3 mm maximum width in the elytra.
Head (Fig. 10) with the maximum width (2.5 mm) in the eyes which are barely convex, with sub-parallel sides, the supraorbital fold slightly prominent and somewhat separated from the eye in dorsal view; epistome sub-truncated in the anterior margin, with fine and spaced punctures in the disk, somewhat denser on the anterior margin; gular groove (Fig. 45) consisting in a shallow central depression, poorly delimited; filiform antennae not surpassing the base of the pronotum. The 1 st antennomere robust, the 2 nd small and little longer than wide, the 3 rd 3.3 times as long as the next two together, from 4 th (1.7 times longer than wide) to 8 th, but progressively decreasing in length; 9 th almost long as wide, 10 th slightly transverse, and 11 th conical at the apex and slightly longer than wide.
Slightly convex, moderately transverse pronotum (Fig. 79); 1.33 times wider than longer, with the maximum width in the middle (4.4 mm wide and 3.3 mm long), narrowing from here ahead and back, acquiring pseudo-pentagonal shape (like T. lateritia), with the apical and basal margins thick, the latter slightly sinuate before the posterior angles that are very obtuse. Base projecting backward, almost angular; very fine and thin punctures, lesser than in the head. Apophysis prosternal (Fig. 115) narrow and lanceolate, slightly surpassing the procoxae; propleurae and prosternum smooth and very bright, with very fine puncture; protibiae almost straight in the inner edge, almost as long as the mesotibiae and both shorter than the metatibiae.
Elytra very convex, not parallel and somewhat depressed in the suture, oval shape, but somewhat elongated: 1.35 times longer than wide (8.5 mm long and 6.3 mm wide), with the maximum width in the middle and from here regularly constricted towards the base and the apex; approximately 2.58 times longer than the pronotum; striae rough, with fine and spaced punctures, with carinae lightly raised, broad and generally somewhat unclear by very superficial and transverse wrinkles of tuberous appearance; humeral angles very marked, the base totally margined and shaped in a closed arc around the base of the pronotum. Abdominal sternites bright and finely punctured, the last truncate at the apex.
Aedeagus (Figure 163) 3.65 mm in length, with the phallobase 1.15 times longer than the parameres which show the sides non-parallel and slightly narrowed towards the base and the apex, and the middle lobe (penis) wide and abruptly narrowed near the apex.
Paratypes: Size 11.2–16 mm total length (13.34 mm average; 13.13 mm males and 13.56 mm females) and 5.4–79 mm maximum width of elytra (6.19 mm average; 5.98 mm males and 6.43 mm females).
Pronotum rather transverse; 1.27–1.58 times wide than long (1.38 times average: 1.36 times males and 1.40 females), with the maximum width in the middle (3.5–5.3 mm wide, 2.6–3.5 mm long).
Elytra: 2.50–2.86 times longer than the pronotum (average 2.70 times), somewhat elongate and oval; 1.27-1.46 times longer than wide (mean 1.37 times).
Aedeagus: 3.4–3,7 mm in length (3.61 mm average), with the phallobase 1.00–1.24 times (1.14 on average) longer than the parameres.
The average size of females is somewhat bigger than males; pronotum slightly more transverse, elytra rather chubbier and protibiae somewhat thicker and shorter than those of males.
Variability of the paratypes: Variability is mainly related to the size, width of pronotum and elytra (varying from depressed in the suture line to fully convex), and the shape of the epistome (truncated or sub-truncated).
Differential diagnosis: The species morphologically and geographically closer to T. stupefacta are T. lateritia Reitter and T. curculionoides (Herbst). It differs from T. lateritia Reitter in the base of the pronotum, showing the basal margin thick and complete and the central lobe not bidentate, elytra with the ribs more evident; aedeagus with the phallobase slightly longer than the parameres, the latter with more sinuous edges not so sharp at the apex. It also differs in the median lobe (penis) which does not narrow so sharply before the apex.
With respect to T. curculionoides (Herbst) it may be differentiated by the pseudo-pentagonal shape of the pronotum, which in T. curculionoides (Herbst) show curved sides and the base barely protruding backwards, and by the punctures, stronger and denser in the latter; the prosternal apophysis narrow and lanceolate in T. stupefacta, while it is wider, with parallel sides and the apex more rounded in T. curculionoides (Herbst); the base of elytra is narrower and curved than in T. curculionoides (Herbst). The aedeagus is less robust in T. stupefacta and with the phallobase, clearly longer than the parameres.
Comments: Viñolas (1991), with specimens from Portugal, revalidated an Andalusian species, T. andalusiaca Kraatz, which Koch (1944a) synonymized with T. corrugata Rosenhauer, from the southeast of Andalusia. However, T. andalusiaca sensu Viñolas is an unpublished species, non-related to T. andalusiaca Kraatz (= T. corrugata Rosenhauer).
Geographical distribution: Species recorded in the littoral and sublittoral areas of southern Portugal, from the mouth of the Mira River to the estuary of the Sado River, entering inland following the fluvial courses.
Etymology: The specific epithet s tupefacta from “stupefactus” Lat. alludes to the great historical confusion of the Tentyria’s taxonomy in the Iberian Peninsula.
