(a) MVZ 268323 (male, left) and MVZ 268307 (female, right) collected from Desa Uaemate along the Tasio-Tibo Road, Kabupatan Mamuju, Provinsi Sulawesi Barat, Sulawesi Island (02.61287S, 119.14238 E, 89 m elev.); (b) Limnonectes larvaepartus female (MVZ 268426) with tadpoles removed from the oviduct. Note the large yolk reserves available to the tadpoles; (c) An in situ adult male L. larvaepartus (JAM 14234) observed calling while perched on the edge of a small pool 2 m away from a 2 m wide stream; several L. larvaepartus tadpoles were present in the pool including the two visible within the yellow circle; (d) dorsal and ventral views of ~stage 25 L. larvaepartus tadpoles (JAM 14271) released by a pregnant female (JAM 14237) at the moment of capture.

Abstract
We describe a new species of fanged frog (Limnonectes larvaepartus) that is unique among anurans in having both internal fertilization and birth of tadpoles. The new species is endemic to Sulawesi Island, Indonesia. This is the fourth valid species of Limnonectes described from Sulawesi despite that the radiation includes at least 15 species and possibly many more. Fewer than a dozen of the 6455 species of frogs in the world are known to have internal fertilization, and of these, all but the new species either deposit fertilized eggs or give birth to froglets.
