Small to large spiders with various color patterns. First leg usually has three pairs of ventral macrosetae on tibia and two pairs on metatarsus. Male palp usually has long and highly coiled embolus, without proximal tegular lobe. Epigynum has a large window with a median septum of various shapes. Vulva is posterior to the window. Copulatory duct is usually long and convoluted. Spermatheca is not strongly swollen, but small and tubular, and not very distinctive from the copulatory duct.

Remarks. Although the carapace of Omoedus and Pystira usually is higher than that of typical Zenodorus and has a shallow concavity at the posterior end, their genitalia do share the same pattern with those of Zenodorus , such as the absence of proximal tegular lobe and the highly coiled embolus of the male palp, the long and convoluted copulatory duct and the small and tubular spermatheca of the vulva. Unpublished molecular data indicate Omoedus , Pystira and Zenodorus form a clade, with Omoedus and Pystira embedded within Zenodorus . Hence, we merge them as one genus and consider Pystira and Zenodorus as junior synonyms of Omoedus . Five species once placed in Pystira and 23 species in Zenodorus ( Platnick 2012) are therefore transferred into Omoedus :
