Paraphrynus is a genus of spiders in the order Amblypygi, the whip spiders, and the family Phrynidae. It is distributed from the southwestern United States to Central America, including several Caribbean islands. Most species are endemic to Mexico.
Taxonomy
This genus can be told apart from Phrynus by observing the patella of the pedipalp, which in Phrynus has one small spine between the two largest, while Paraphrynus has two. It can be distinguished from Acantophrynus by its lack of spines in the frontal region of the carapace. The remaining member of the family Phrynidae, Heterophrynus, does not seem to be sympatric with any species of this genus.
There are about 18 species:[1]
- Paraphrynus aztecus (Pocock, 1894)
- Paraphrynus baeops (Mullinex, 1975)
- Paraphrynus chacmool (Rowland, 1973)
- Paraphrynus chiztun (Rowland, 1973)
- Paraphrynus cubensis Quintero, 1983
- Paraphrynus emaciatus Mullinex, 1975
- Paraphrynus grubbsi Cokendolpher and Sissom, 2001
- Paraphrynus laevifrons (Pocock, 1894)
- Paraphrynus leptus Mullinex, 1975
- Paraphrynus macrops (Pocock, 1894)
- Paraphrynus mexicanus (Bilimek, 1867)
- Paraphrynus pococki Mullinex, 1975
- Paraphrynus raptator (Pocock, 1902)
- Paraphrynus reddelli Mullinex, 1979
- Paraphrynus robustus (Franganillo, 1931)
- Paraphrynus velmae Mullinex, 1975
- Paraphrynus viridiceps (Pocock, 1894)
- Paraphrynus williamsi Moreno, 1940
Biology
Like other amblypygi, the species in this genus are nocturnal predators that dwell in moist microenviornments. Some species are troglophiles and some are true troglobites.[2] They feed upon insects and other arachnids. They use their first pair of legs as sensory organs and their spiny pedipalps to snare prey.
