Mexican species of the genus Probles Förster (Hymenoptera: Ichneumonidae: Tersilochinae).

Mexican species of the genus Probles Förster are reviewed. Twelve species have been discovered from Mexico, all belong to the subgenus Euporizon Horstmann and are new to science: P. alejandroi Khalaim, sp. nov., P. belokobylskii Khalaim, sp. nov., P. clypeola Khalaim, sp. nov., P. contrerasi Khalaim, sp. nov., P. juanitae Khalaim Ruíz-Cancino, sp. nov., P. lunai Khalaim, sp. nov., P. megasoma Khalaim Ruíz-Cancino, sp. nov., P. miquihuana Khalaim Ruíz-Cancino, sp. nov., P. picus Khalaim Ruíz-Cancino, sp. nov., P. spectabilis Khalaim Ruíz-Cancino, sp. nov., P. xalapana Khalaim, sp. nov. and P. zacapoaxtlana Khalaim, sp. nov. One species, P. megasoma sp. nov., is also recorded from Costa Rica. An identification key to species of Probles occurring in Mexico is given.

Three new species of the genus Probles Förster (Hymenoptera, Ichneumonidae, Tersilochinae) from South Korea.

Three closely related species of the genus Probles Förster, P. fulgida sp. n., P. korusa sp. n. and P. rukora sp. n., belong to the subgenus Euporizon Horstmann and differ from other Palearctic species of the genus by a combination of long and apically weakly sinuate ovipositor and short temple. These three species are assigned to a newly designated fulgida species-group, and a portion of the key for identification of this species-group is provided. Based on the shape of the ovipositor apex, the fulgida species-group resemble members of the subgenus Microdiaparsis Horstmann but are distinct in having a much shorter temple.
