A key to the Oriental species of Passaloecus Shuckard (Crabronidae: Pemphredoninae: Pemphredonini) is provided. Four new species are described and illustrated: P. columnaris and P. labrinigratus from Yunnan, China, P. multituberculatus from Zhejiang, China, and P. petiolatus from Tibet, China. In addition, four Oriental species are reported, of which P. clypealis Faester and P. monilicornis Dahlbom are recorded from the Oriental Region for the first time.
