Recent studies on the pholcid fauna of Central America have elevated the number of known Costa Rican species from 11 to 28 in only two years. The present paper summarizes the scattered literature and adds two new species as well as three undescribed species, bringing the total number to 33 species representing seven genera. An illustrated key is presented. An annotated list summarizes the information available about taxonomy, morphology and natural history of all known Costa Rican pholcids. The two new species are Anopsicus tico n.sp. from the Central Valley, and Physocyclus guanacaste n.sp. from the Santa Rosa National Park, Guanacaste. The male of Metagonia hondura Huber, 1997 is described and illustrated for the first time. Old pholcid records from Costa Rica are discussed, and types of unsufficiently well described species are redescribed, including all previously known Costa Rican Anopsicus species (A. chiriqui Gertsch, 1982; A. concinnus Gertsch, 1982; A. facetus Gertsch, 1982; A. turrialba Gertsch, 1982) as well as Metagonia osa Gertsch, 1986 and M. selva Gertsch, 1986. New localities are given for twelve species; of these, four are new for Costa Rica: Anopsicus chiriqui Gertsch, 1982; \‘Coryssocnemis\’ viridescens Kraus, 1955; Physocyclus globosus (Taczanowski, 1873); and Smeringopus pallidus (Blackwall, 1858). The genera Coryssocnemis Simon, 1893 and Smeringopus Simon, 1890 are new for Costa Rica. It is argued that carefully directed collecting in certain areas and habitats will probably lead to a further considerable increase in known species.

Se realizó la revisión taxonómica de Physocyclus Simon, 1893. Se redescribieron 12 especies con descripciones originales incompletas. Se presentan nuevos registros de distribución para la mayoría de las especies. Se describe por primera vez el macho de Physocyclus lautus Gertsch, 1971. Se describen 13 especies nuevas: Physocyclus franckei sp. nov., Physocyclus michoacanus sp. nov., Physocyclus brevicornus sp. nov., Physocyclus gertschi sp. nov., Physocyclus huacana sp. nov., Physocyclus montanoi sp. nov., Physocyclus marialuisae sp. nov., Physocyclus sprousei sp. nov., Physocyclus darwini sp. nov., Physocyclus rothi sp. nov., Physocyclus sarae sp. nov., Physocyclus platnicki sp. nov. y Physocyclus paredesi sp. nov. Se presentan claves dicotómicas para la identificación de las especies del género, una clave para machos y una para hembras.

With 30 species and a natural distribution in North America, 28 confined to Mexico, Physocyclus Simon 1893 is the most diverse genus within the pholcid spider subfamily Arteminae. This paper provides the first phylogenetic test of the genus\’s monophyly through a cladistic analysis of 54 morphological characters using equal and implied weighting. The equally weighted analysis found 12 most parsimonious trees, whereas the analysis with implied weights varying the concavity values (K 5 6\–10) found five or six most parsimonious trees. The monophyly of the genus Physocyclus is supported by three synaphomorphies: 1) the paired ventral apophysis on the anterior part of the epigynum; 2) the lateral constraints in the middle part of the epigynum; and 3) the arc of the uterus, with a single sclerotized projection on the anterior part. The genus Physocyclus contains two clades treated as species groups: the globosus group, with 11 species, and the dugesi group with 19 species. The species relationships within the globosus group were better resolved than those in the dugesi group. The globosus group has a biogeographical distribution pattern in the Mesoamerican and Mexican Mountain biotic components, whereas the dugesi group has a distribution pattern in the Mesoamerican and Continental Nearctic biotic components. Given the complex biogeography in Mexico, apparently a large-scale vicariant event separated the two major clades within the genus Physocyclus.

A new species of spider from Michoacán, Physocyclus peribanensis sp. nov. is described. This description is based on a male holotype and one female paratype. Also, the first description of the female of Physocyclus paredesi Valdez-Mon- dragón from Oaxaca, Mexico is provided, as well as the redescription of the male. This paper provides a cladistic reanal- ysis of the spider genus Physocyclus Simon, corroborating the monophyly of the genus with morphological data. The phylogenetic reanalysis was done with 54 morphological characters (44 binary and 10 multistate) using equal and implied weighting approach. The equal weighting analysis found two most parsimonious trees, whereas the analysis with implied weighting found just one most parsimonious trees with the concavity values (K= 5\–10). The genus Physocyclus is com- posed by two clades or species groups: the globosus and the dugesi groups. Physocyclus peribanensis sp. nov. belongs to the dugesi group composed of 21 species, and P. paredesi to the globosus group composed of 11 species. With the new species described here, the number of known species of the genus Physocyclus increases to 32 species. The globosus group has a biogeographical distribution pattern in the Mesoamerican and Mexican Mountain biotic components, whereas the dugesi group has a biogeographical distribution in the Mesoamerican and Continental Nearctic biotic components.
