Atractides (Atractides) cultellatus (K. Viets, 1930)

Fig. 7

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 single female specimen from Portugal generally matches the description of A. cultellatus , which was originally described from a single female collected from Rio Manzanares, Spain (K. Viets, 1930). Atractides valencianus (K. Viets, 1930), a species originally described from Spain and later reported by Gerecke (2014) from Sardinia, resembles A. cultellatus in the presence of a lineated integument, a slenderer I-L-6, the more spaced sword setae of I-L-5, and Vgl-1 not fused to Vgl-2, but it differs in having P-2 completely devoid of thickening or rounding in females ( Gerecke 2003).
