A new species of jumping spider, Orcevia vinhlong sp. n., is described and illustrated based on both male and female specimens collected from Vinh Long Province, southern Vietnam. New species is similar to O. deelemanаe, O. keyserlingi, O. kuloni, O. meinei, O. pakse, and O. timburtoni in its mottled habitus covered with dark grey setae, but it can be distinguished by the specific structure of the male retrolateral tibial apophysis (RTA) apex. The female of O. vinhlong sp. n. is diagnosed by a flat epigyne lacking a median septum, with slender, parallel insemination ducts and large, globose receptacles. Observations on natural history of new species reveal that it inhabits dry leaf litter of banana trees (Musa sp.) and constructs retreats on the bark of starfruit trees (Averrhoa carambola). Notably, these retreats are often camouflaged with ant carcasses, suggesting a potential myrmecophagous behavior. The species is currently known only from its type locality in Vietnam.
