| 9:07a | [Entomology • 2024] Epelaspis lulo, E. wagneri, ... • Revisiting the Darwin Wasp Genus Epelaspis Townes, 1970 (Hymenoptera: Ichneumonidae: Phygadeuontinae): Five New Species, New Records and A Key to Neotropical Species
Abstract The Darwin wasp genus Epelaspis Townes, 1970 (Hymenoptera: Ichneumonidae: Phygadeuontinae) is studied in some countries of South America. We recorded the genus for the first time in Colombia, and five new species are described: Epelaspis boteroi Lima & Fernandes, sp. nov., Epelaspis constantinoi Lima & Fernandes, sp. nov., Epelaspis lulo Lima & Fernandes, sp. nov., Epelaspis tavoi Lima & Fernandes, sp. nov., and Epelaspis wagneri Lima & Fernandes, sp. nov.. Furthermore, E. anorus Townes, 1970 is newly documented for Brazil, while the geographic ranges of E. renatoi Graf & Kumagai, 1996 and E. ketiae Graf & Kumagai, 1996 are extended within the country. Digital images, maps, and a key to Neotropical Epelaspis species are provided. Hymenoptera, Andean Region, Andean Cloud Forest, Brazil, biodiversity, Colombia, parasitoid wasps  Adriane G. M.

| 2:47p | [Paleontology • 2024] Caipirasuchus catanduvensis • A New Species of vocalizing Crocodyliform (Notosuchia: Sphagesauridae) from the Late Cretaceous of Brazil
ABSTRACT Caipirasuchus is a genus of sphagesaurid notosuchian from the Bauru Basin (Upper Cretaceous), southeast Brazil. They were small-sized herbivorous/omnivorous animals, that measured around 1 metre in length, and had a wide diversity and geographical dispersion in the basin. Here, we diagnosed the 6th species of the genus, originating from sandstones of the Adamantina Formation in the municipality of Catanduva, São Paulo State. Caipirasuchus presents a significant variation in the morphology of structures in the choana region. In particular, the new species has chambers in the wings of the pterygoids that connect with an extension of the airways, suggesting a region of resonance used in vocalisation. The different palatal structures in Caipirasuchus may be related to distinct bioacoustic signatures and indicate apossible improvement in the social organisation of Caipirasuchus.
