Genus Camptocosa
Synonyms and other taxonomic changes
This was a new genus erected by Dondale, Jiménez & Nieto (2005) based on the type species Allocosa parallela (Banks, 1898).
Explanation of Names
Dondale, Jiménez & Nieto, 2005
On name etymology, quote: "The name Camptocosa is derived from the Greek word kamptos, meaning bent, and cosa, from the Greek Lycosa, a genus of wolf spiders. The name refers to the distinctively bent tip of the median apophysis on the palpus of the male. The name is regarded as feminine in gender."(1)
2 species in BugGuide's range (North America north of Mexico).(2)
Adult males have a conspicuous brush of black hairs on their front tibiae (same as some Schizocosa), but females do not. Males and females both have dark bands/annulations on the fourth metatarsi, sometimes more distinctive in females. See Slowik & Cushing (2008) for carapace diagrams; they are different in each of the two species in this genus.
Camptocosa parallela: southwestern states (Arizona, California, southern Nevada, New Mexico, southern Utah, Texas).(1)
Camptocosa texana: southwestern states (so far, published records include only Arizona(3) & Texas(1)).
See Also
Carapace patterns are similar to some Schizocosa, Rabidosa, and Pardosa (e.g. P. distincta). Male black tibial brushes on front legs similar to some males in Schizocosa.
