Fig. 6

Material examined.

Portugal, Santarém, Caniceira stream, 39.4110°N, 8.2615°W, 25.v.2022, leg. Jovanović, 1♂, (sequenced; Table 1 ), dissected and slide mounted (RMNH) .

Remarks.

The Portuguese specimen molecularly analyzed in this study perfectly matches the description of T. hispanica , a species originally described on basis of specimens collected from a stream near Algeciras in Spain ( Lundblad 1956).

Description.

Male -Dorsal shield without a colour pattern, as shown in Fig. 6A ; area of primary sclerotization of the dorsal plate with two dorsoglandularia; gnathosomal bay U-shaped, proximally rounded; Cxgl-4 subapical; suture line of Cx-IV evident, medially starting from posterior margin of genital field in a right angle to the main idiosoma axis; genital field subrectangular; ejaculatory complex conventional in shape (Fig. 6E ); excretory pore located on the line of primary sclerotization; gnathosoma ventral margin curved, rostrum strongly elongated (Fig. 6D ); P-2 longer than P-4; P-2 ventral margin straight, P-2 and P-3 ventrodistal protrusions blunt, laterally flattened, P-4 with a well-developed ventral tubercle bearing one longer and three shorter setae (Fig. 6C ).
