We here report nine species of Tephritidae and five species of Platystomatidae from North Korea deposited in the Hungarian Natural History Museum (five new Korean records marked with asterisks): Acidiella pachypogon, Campiglossa $absinthii^*$, C. hirayamae, C. $loewiana^*$, Sphaeniscus atilius, Tephritis $brachyura^*$, Tephritis $sinensis^*$, Trupanea amoena, Xanthomyia $alpestris^*$, Rivellia alini, R. apicalis, R. asiatica, R. longialata, and R. nigroapicalis. Except for C. hirayamae, all other species are newly recorded in North Korea. As a result, a total of 22 tephritid and five platystomatid species are recognized for the North Korean tephritoid fauna. In South and North Korea together, a total of 120 nominal species of six tephritoid families are now officially recognized (1 Lonchaeidae, 1 Pallopteridae, 1 Ctenostylidae, 14 Platystomatidae, 14 Pyrgotidae, and 89 species of Tephritidae).
