Type species. Pisaura Simon 1885 .

Diagnosis. The carriage of the egg sac in the female’s chelicerae and the subsequent construction of a nursery web to protect the egg sac are two characters that distinguish Pisauridae from both Trechaleidae and Lycosidae ( Carico, 1993: 228) . Pisauridae also differ from Trechaleidae as the median apophysis of the male palpus is neither large nor distally situated and lacks a dorsal embolic groove that extends distally into an apical groove. Unlike Trechaleidae , pisaurid eggsacs do not have a ‘‘skirt’’ on the seam of the discoid egg sac ( Carico 1993: fig. 6). Pisauridae can also be distinguished from Lycosidae by the lesser degree of recurvature in the posterior eye row and the male palp usually bears a tibial apophysis. The presence of the distal tegular projection (DTP) and the presence of pseudosegmented tarsi could represent possible synapomorphies of Pisauridae ( Santos 2007) , although this latter character can also be found in Trechaleidae .
