Description: Holotype (Fig. 192). Elongated body, 2.26 times longer than broad; black tegument, almost mate and micro- reticulate. Total length: 12.2 mm; maximum width in elytra: 5.4 mm.
Head: maximum width 2.5 mm at the base of the eyes which are somewhat convex; supraorbital folds scarcely enhanced; epistome truncate in the anterior margin and with a tiny tooth in the middle; punctures fine and spaced; gular groove consists of a broad but badly delimited hollow in the centre; antennae filiform, not reaching the base of the pronotum; the 1 st antennomere robust, the 2 nd small and barely longer than broad, 3 rd about 3.3 times longer than broad and similar to the 4 th and 5 th together, from the 4 th (1.8 times longer than broad) to the 8 th longer than broad, but progressively decreasing in length; the 9 th almost as long as broad; the 10 th slightly transverse and the 11 th conical at the end and slightly longer than broad.
Pronotum (Fig. 75) feebly convex, transverse, 1.36 times broader than long, with the maximal width closer to the apex than to the base (4.0 mm broad and 2.9 mm long), narrowing from here in a straight line towards the base and in closed curve towards the apex; sub-cordiform shape. Base of pronotum totally margined and sinuate before the posterior angles. Central lobe truncate, exceeding the posterior angles which are almost straight. Punctures very fine and sparse, less noticeable than in the head, almost imperceptible; prosternal apophysis, with parallel sides and narrowed towards the apex, rounded at the end, and slightly bent in ventral view, slightly surpassing the pro-coxae; propleurae and pro-sternum with the surface little bright, and rather punctured; protibiae long and sinuous on its inner edge, almost as long as mesotibiae and 1/3 shorter than the metatibiae.
Elytra rather convex, elongated, oval in shape, flattened on the disk, 1.39 times longer than broad (7.5 mm length and 5.4 mm broad), with the maximal width on middle, equally narrowing towards the base and the apex, slightly rough-striated, and sparsely punctured; 2.6 times longer than pronotum; humeri well marked; the base cut in arc and with the basal margin erased, only indicated next to the humeri; Abdominal sternites not very bright and with fine but clearly noticeable punctures; the last sternite truncated at the apex.
Aedeagus like in Fig. 158 but smaller in size, length 3.45 mm.
Sexual dimorphism: Females showing shortest protibiae, with the inner edge straight.
Paratypes: Size: 12.2–15.5 mm in length (13.7 mm on average) and 5–6.3 mm maximum width of elytra (5.73 mm on average).
Pronotum rather transverse, 1.26–1.38 times wider than long (1.33 average), with the maximum width before the middle (3.9–4.6 mm wide, 2.9–3.5 mm long).
Females with shorter protibiae and straight inner edge.
Elytra 2.5-2.81 times longer than the pronotum (mean 2.65 times); rather ovate and elongated, of 1.39–1.56 times longer than wide (mean 1.47 times).
Aedeagus: Length 3.4–3.9 mm (3.56 mm average); parameres and phallobase similar in length.
Variability of Paratypes: variations are mainly observed in length, width, and roughness of elytra and in the basal lobe of the pronotum, which varies from noticeably truncated to slightly sinuate.
Differential diagnosis: T. sinuatocollis escalerai differs from T. s. sinuatocollis in the pronotum, which is more transverse, with maximum width before the middle, cordiform, with the basal lobe more protruding, truncated and not clearly sinuate (Figs. 74, 75); the head is smaller and with the eyes slightly more convex; the elytra are somewhat depressed in the middle line; shorter, wider and oval shape, and with steeper slope towards the apex; usually, chubbier and smaller specimens, and with the antenna and the legs somewhat more graceful.
Geographical distribution: This subspecies is present in the Mediterranean coast, from Gata’s cape (Almería) to Alicante.
Etymology: Subspecies devoted in memoriam of the great entomologist Dr. Manuel Martínez de la Escalera.
