Brief Summary

    Ochyroceratidae: Brief Summary
    provided by wikipedia

    Ochyroceratidae is a six-eyed spider family, with 154 described species in 14 genera.

    Ochyroceratids are common inhabitants of the tropical forest litter and caves in South Africa, the Caribbean and Asia, especially species rich in the Indo-Pacific, where they constitute one of the ecological counterparts of the Linyphiidae of the northern temperate zone.

    They build small, irregular sheet-webs in dark, damp places around leaves, sticks and logs, and typically carry their eggs in their chelicerae until they hatch. Their body length ranges from 0.6 to 3 millimeters. Some species with very long legs (Althepus, Leclercera) are superficially similar to Pholcidae.

    At least one species in the genus Theotima (the only 0.9mm long T. minutissima) was shown to be parthenogenetic.

    Brief Summary
    provided by EOL authors

    The spider family Ochyroceratidae includes 161 described species (Platnick 2013). This is a tropical family of six-eyed spiders, but two species have been recorded as far north as southern Florida (U.S.A.) (Paquin and Ubick 2005). Although some ochyroceratids are associated with caves, the majority of species occur in forest litter, where they spin small irregular webs or finely mazed sheet webs (Deeleman-Reinhold 1995). In the tropics, ochyroceratids appear to be an ecological counterpart of linyphiids in north temperate regions (Deeleman-Reinhold 1995). Edwards et al. (2003) documented parthenogenesis in Theotima minutissima (a species found in the tropics of Africa, the Caribbean, and Asia) and very briefly reviewed the literature on parthenogenesis in spiders. According to Edwards et al. (2003), female ochyroceratids typically carry their eggs in their chelicerae until they hatch. For Theotima minutissima, Edwards reported that clutch size ranged from 1 to 9, with most clutches composed of 4 to 6 eggs. The existence of Theotima minutissima males has been debated, but Paquin and Ubick (2005) illustrate what may be a male specimen of this species (these authors note that parthenogenesis does not preclude the possibility of males occurring at extremely low abundance or only under particular conditions). According to Bradley (2013), Theotima minutissima could easily be mistaken for a midget cave spider (Leptonetidae) or long-legged cave spider (Telemidae), but has proportionately shorter legs than spiders in these other families.

Comprehensive Description

    Ochyroceratidae

    Ochyroceratidae is a six-eyed spider family, with 154 described species in 14 genera.

    Ochyroceratids are common inhabitants of the tropical forest litter and caves in South Africa, the Caribbean and Asia, especially species rich in the Indo-Pacific, where they constitute one of the ecological counterparts of the Linyphiidae of the northern temperate zone.[3]

    They build small, irregular sheet-webs in dark, damp places around leaves, sticks and logs, and typically carry their eggs in their chelicerae until they hatch. Their body length ranges from 0.6 to 3 millimeters. Some species with very long legs (Althepus, Leclercera) are superficially similar to Pholcidae.[3]

    At least one species in the genus Theotima (the only 0.9mm long T. minutissima) was shown to be parthenogenetic.
