ABSTRACT. In Vietnam, seven species of the genus Trypoxylon (Hymenoptera: Crabronidae) have been recorded. In the present work, we study the Trypoxylon species from northern Vietnam resulting in records of 14 species, namely T. bicolor F. Smith, 1856; T. cagrum Tsuneki, 1979; T. fulviventre Tsuneki, 1979; T. interruptum Tsuneki, 1978; T. orientale Cameron, 1904; T. paeninsulicola Tsuneki, 1979; T. petiolatum F. Smith, 1858; T. pileatum F. Smith, 1856; T. prominens Tsuneki, 1979; T. rufigaster Tsuneki, 1979; T. thaianum Tsuneki, 1961; T. tomi Tsuneki, 1979; T. varipilosum Cameron, 1901; and T. yumi Tsuneki, 1979. Of these, except T. petiolatum and T. prominens, the others are recorded for the first time from the country. Altogether, 19 species of the genus Trypoxylon have been recorded from Vietnam. A key to the Trypoxylon species from northern Vietnam is presented.

KEY WORDS: new record, species group, taxonomy, Trypoxylon, Crabronidae, northern Vietnam.
