A survey of 26 species of Salticidae newly collected from the Na Hang Nature Reserve (NW Vietnam) is presented. A new monotypic genus is established: Rhenefictus gen. n. (type species: Rhenefictus tropicus sp. n.). Nine new species are described: Chinophrys pulcra sp. n. (♀), Myrmarachne fredwanlessi sp. n. (♂♀), M. singulare sp. n. (♂), Orcevia terrestre sp. n. (♂), Pancorius nahang sp. n. (♀), P. pseudomagnus sp. n. (♀), Rhenefictus tropicus sp. n. (♂), Thiania zabkai sp. n. (♂♀), Toxeus yamasakii sp. n. (♂♀). Three new synonyms are established: Cheliceroides Żabka, 1985 syn. n. with Colopsus Simon, 1902; Langerra longicymbia Song & Chai, 1991 syn. n. with Langerra oculina Żabka, 1985; Thyene radialis Xie & Peng, 1995 syn. n. with Thyene orientalis Żabka, 1985. One synonymy is reinstated: Myrmarachne gorontaloensis Yamasaki, 2012, syn. rev. with M. bicuspidata Yamasaki, 2012. Two new combinations are proposed: Bathippus brevipalpis (Roy, Saha & Raychaudhuri, 2016), comb. n., and Colopsus longipalpis (Żabka, 1985), comb. n., both ex Cheliceroides.
