From Goodnight & Goodnight 1977 (p.162), "For the complete synonymy of this genus, see Goodnight and Goodnight, 1953. Cosmetids with simple untoothed claws on the third and fourth legs, with more than six segments in the tarsus of the first leg. Distitarsi of both first and second tarsi with three segments. Dorsum with five areas, variously armed with tubercles and spines. Secondary sexual characteristics of the male usually present as increased spination of the femur the fourth leg."

From Goodnight & Goodnight 1953 (p.55) "Cosmetids with simple untoothed claws on the third and fourth legs, with more than six segments in the tarsus of the first leg. Distitarsi of both first and second tarsi with three segments. Dorsum with five areas, variously armed with tubercles and spines. Secondary sexual characteristics of the male usually present as increased spination of the femur of the fourth leg".

Included species Edit

For Paecilaema obscurum (Pickard-Cambridge, 1905) see Rhaucus quinquelineatus Simon 1879

Notes Edit

Kury & Alonso-Zarazaga 2011 say Paecilaema (or Paecilima) is neuter, the inflection in gender should be corrected with the species in: P. acuriguense González-Sponga, P. amazonicum González-Sponga, P. campoeliasense González-Sponga, P. eutypum (Chamberlin) (from the latinized Greek adjective eutypós “that can be shaped”), P. festivum Kury, P. laterale Goodnight & Goodnight and P. oblongum González-Sponga. The name P. albantica (Roewer) is doubtful, because it is not a Latin orthodox word, but that could be an adjective.
