Remarks.

Attulus striatus is a small-bodied Northern species with distinctively striped males, from sphagnum bogs. Although we were unable to obtain molecular data for it or the similar A. rivalis and A. cutleri , these three species can be placed into subgenus Attulus with some confidence, based on their boxy carapaces (resembling the other Attulus (Attulus) rather than Attulus (Sitticus) ), and the genitalic similarities with subgenus Attulus , including the two small posterior openings of the epigyne on either side of a narrow triangular RTA coupling pocket. Prószyński (1980) considered them close to the floricola group in particular.

We reinstate S. rivalis Simon, 1937 as a distinct species (contra Prószyński 2017a), accepting Logunov’s (2004) clear evidence for their distinction (primarily, in the rotation of the bulb of the palp). Attulus rivalis is known from France, also from sphagnum bogs.
