Description: Holotype (♁) ( Fig. 216 ): Elongated, robust body; black, smooth, and not very bright tegument. Size 14 mm long and 5.9 mm maximum width in the elytra.

Head ( Fig. 30 ) wider than long, with the maximum width (2.6 mm) in the genae that are thick and prominent; slightly convex eyes; temples converging towards back; very prominent supraocular fold, with two elongated depressions and converging backwards on both sides, above the insertion of the antennas; the surface of the disc is irregular and densely punctured, as well as the epistome, which is rounded and without tooth clearly perceptible; straight and narrow gular groove ( Fig. 64 ), moderately deep on the sides; long and filiform antennas, non-exceeding the base of the pronotum, the 1 st antennomere sturdy, the 2 nd small and as length as wide, the 3 rd 2.6 times longer than wide and barely shorter than the 4 th and 5 th together, from 4 th to 8 th one and a half times longer than wide, the 9 th almost as long as wide, the 10 th slightly transverse and the 11 th conical at its end and slightly longer than wide.

Transverse and somewhat convex pronotum ( Fig. 100 ), 1.3 times wider than long, with well-marked and moderately dense punctures, quite similar to those that of the head; sides in regular curve, somewhat more narrowed towards the base than at the apex, the base thickly margined, clearly prolonged in curved backwards and bisinuate before the posterior angles that are obtuse; prosternal apophysis ( Fig. 135 ) with parallel sides and rounded apex, depressed longitudinally in the centre and 1.7 times longer than wide; smooth and somewhat brighter propleurae and prosternum, punctures slightly dense and well-marked; densely punctured mesosternum; and metasternum thicker punctured in its anterior half; protibiae somewhat shorter than the metatibiae and with the inner edge slightly sinuous and curved.

Elytra convex, in elongated oval, one and a half times longer than wide and almost three times longer than the pronotum, the maximum width in the middle, almost equally narrowed towards the base and apex, with well indicated punctures and barely finer than in the pronotum; well-marked humeri, protruding from the base that fits to the pronotum and is completely margined; urosternites smooth and provided with fine, but well-marked and moderately dense punctures.

Aedeagus of 4 mm in length, with the parameres narrowed, drawing a slightly sinuous line, from the base to the apex and 1.3 times longer than the phallobase, similar to the type form, but higher average size.

Paratypes: Size 13.3–16.2 mm length (14.7 mm in average) and 5.5–7 mm maximum wide of elytra (6.3 mm in average).

Pronotum convex and barely transverse, 1.24–1.47 times wider than long (1.36 times in average: 1.32 times in males and 1.38 in females); the maximum wide in the middle (3.7–5.1 mm wide and 2.9–3.8 mm length).

Elytra 2.57–3.09 times longer than the pronotum (2.81 in average), ovate and elongated, 1.32–1.54 times longer than wide (1.45 times in average).

Aedeagus large, 3.5–4.4 mm in length (4.05 mm in average), parameres 1.10–1.34 times (1.21 in average) longer than the phallobase.

Sexual dimorphism clearly observable only in the protibiae; which are slightly shorter, wider and with the internal border straight in the females. Likewise, females tend to have somewhat more transverse the pronotum and the base barely protruding backwards, slightly smaller average size, and commonly the elytra proportionally somewhat longer and wider.

Variability of the paratypes: In addition to the morphometric variations already indicated, the variability refers to the greater or lesser brightness of the cuticle, the intensity of the punctures, the surface of the elytra showing signs of roughness or striation, and to the features of the head less accented.

Differential diagnosis: T. velox serrana ssp. nov. differs from T. velox f.t. and T. velox ssp. circumvoluta , by the great size and more robust body; the tegument less bright and with more noticeable punctures; the shape of the head wider than long and with the epistome less projected forward; the pronotum less transverse in the middle; the elytra proportionally longer than in T. velox , and somewhat narrower towards the humeri, that are acuter. In addition, it differs from T. circumvoluta by the more graceful legs and the characteristic roughness of the elytra that this taxon shows.

Geographic distribution: Species typical from the Central System Mountains, particularly from the western area; where the provinces of Cáceres, Ávila and Salamanca converge.

Etymology: The specific epithet “ serrana” refers that it is a typical species of the “sierras”, Spanish term for mountains.
