Description of Apechthis cantika sp. n. from Sulawesi Is., Indonesia with redescription of the holotype of A. taiwana Uchida (Hymenoptera, Ichneumonidae, Pimplinae)

Apechthis cantika sp. n. (Ichneumonidae: Pimplinae) is described from the island of Sulawesi, Indonesia. This is the first known representative of the genus in Indonesia and also the southernmost record of Apechthis in the Oriental region, extending the known distribution far southwards. Discovery of a second yellow Apechthis in the Oriental region, following A. taiwana Uchida, suggests that the genus suddenly changes its body colour entirely from black to yellow towards the equator, independently in both the Oriental and Neotropical regions. The holotype of A. taiwana, apparently closely related to A. cantika sp. n., is also redescribed for comparison
