Description of the holotype ( Fig. 18 , 20):

Length: 3.25 mm (without rostrum).

Venter: With a constantly deep and wide pectoral canal, from the fore-margin of the prosternum to the midcoxae, terminating between the mid-coxae in an equally deep mesosternal receptaculum ( Fig. 18 ); the distance between the prae-coxae is large, as is their diameter. The brink of the mesosternal receptaculum is semicircular and sharp-edged; base of the receptaculum with a step. 1 st and 2 nd abdominal segment of the male with a wide and flat hollow.

Head & Rostrum: Without eyes; T. cadizensis belongs to the ‘long-nosed’ species: rostrum brown, 3.8x (♂) as long as wide between the insertions of the antennae, without a mid-edge, but on each side with a short edge; insertions of the antennae near the apex, approximately at the end of the first third (♂).

Pronotum: 1.16x as long as wide; widest at the end of the basal second fifths of the pronotum; narrowing rectilinearly laterally towards the fore-margin, clearly less rounded than towards base. Disc of pronotum flattened, with fine, deep and extensively placed punctures, covered with numerous round scales and isolated, scarce bristles. The fore-margin of the pronotum with a slight indentation in the middle.

Elytra: Brown-russet, flattened (much flatter and broader than those of T. morandae , see Fig. 19 ), 1.72x (♂) as
