| 2:54p | [Botany • 2024] An Overview of Astrocaryum (Arecaceae: Bactridinae) Types from Brazil described by João Barbosa Rodrigues
Abstract João Barbosa Rodrigues, a renowned Brazilian botanist, spent years intensively studying Orchidaceae and Arecaceae and oversaw two important institutions in Brazil: the Museu Botânico do Amazonas and the Jardim Botânico do Rio de Janeiro. However, when it comes to his taxonomic studies, there are controversies about the existence of specimens mentioned in the protologues of his new species. For example, for the palm genus Astrocaryum, several issues have arisen regarding identifying and designating nomenclatural types of the species he described. Different researchers presumed that the entire collection of types was destroyed after the Museu Botânico do Amazonas closed and due to natural disasters, that affected his collections in city of Rio de Janeiro. Thus, in this study we investigated the names of Astrocaryum described by Barbosa Rodrigues. We conducted a comprehensive investigation of Barbosa Rodrigues’ works to determine the origin and current location of the possible nomenclatural types associated with the Astrocaryum species he described. Additionally, we reviewed the designations proposed by Jan Wessels Boer and Sidney Glassman for these species in the previous century. Based on our thorough search, we confirmed the absence of the specimens mentioned in the protologues of these species. Furthermore, we substantiated the typifications made by Wessels Boer and Glassman, which were based on illustrations by Barbosa Rodrigues. Our findings confirm the assignment of six lectotypes and twelve neotypes for Astrocaryum based on the Shenzhen Code. illustrations, lectotype, Museu Botânico do Amazonas, neotype, palms, Monocots Gustavo Pereira LIMA, Gabriela AMORIM, Eduardo Bezerra de ALMEIDA Jr. 2024.

| 3:42p | [Herpetology • 2024] Leptobrachella aurantirosea • A New Leaf-Litter Frog of Leptobrachella (Anura: Megophryidae) from Tay Con Linh Mountain, Northern Vietnam
Abstract A new Leptobrachella species is described from Vietnam based on six specimens collected from Tay Con Linh Mountain, Ha Giang Province, Vietnam. Morphologically, the new species can be distinguished from its congeners based on the combination of the following characteristics: size medium (SVL 21.3 – 24.4 in males); skin on the entire dorsum relatively smooth with some small tubercles; webbing between toes and fingers absent with weak lateral fringes; dorsum orangish-yellow with pink pigments, a gray patch between eye in a triangle shape and a gray patch in Λ shape in the center of the back, in the posterior of dorsum with a pattern, which seems to connect with the bars on the upper side of thigh and tibia when the hindlimbs shrank; ventral side of body smooth, throat pinkish-white and chest cream white with some gray blobs on the belly and grayish blobs on the throat; lower jaw gray with white spots, iris bicolor. The genetic distance between the new species and other Leptobrachella species ranges from 8.15 to 10.43% (compared to L. namdongensis and L. puhoatensis, respectively).

| 3:42p | [Herpetology • 2025] Rhacophorus boeadii • Morphological and Genetic Analysis of Sulawesi Rhacophorus (Anura: Rhacophoridae) and Description of A Fourth Species endemic to the Island
Abstract A new species of tree frog of the genus Rhacophorus is described from two different localities on Sulawesi Island, Indonesia. The new species is divergent morphologically and genetically, and is deeply nested within the monophyletic group of endemic Sulawesian Rhacophorus comprising R. edentulus, R. georgii, and R. monticola. The new species has a combination of distinctive morphological characteristics that distinguishes it from other Rhacophorus species, including from other Sulawesian Rhacophorus: medium size SVL 40.4–44.6 mm in males; 48.1–54.2 mm in females, males have sloped snout in lateral view, presence of vomerine teeth, absence of a bony crest in the occipital region of the skull, dorsal skin coarsely granular with white-tipped keratinized asperities, flank with white blotched pattern, dermal flaps absent on limbs, heel without dermal appendage, and tuberculate cloaca. The discovery of the new species enhances knowledge of the diversity of endemic Sulawesian amphibians and requires future conservation efforts, especially in light of ongoing threats such as agricultural expansion.
