| 3:56a | [Funga • 2025] Xerocomus garhwalensis & X. rishikeshinus • Two New Species of Xerocomus (Boletales: Boletaceae) from the Indian Himalaya
Abstract Xerocomus garhwalensis and Xerocomus rishikeshinus (Boletales, Basidiomycota) are described as species new to science from specimens collected in the Himalayas of northwestern India. Both were found in forests dominated by banj oak (Quercus leucotrichophora A. Camus), and they presumably form ectomycorrhizal associations with this tree species. Xerocomus has been variously defined morphologically, and a number of the species now assigned to the genus are sometimes considered to be members of the genus Boletus. The two new species were placed in Xerocomus largely on the basis of DNA sequence data, which are still rather limited for the assemblage of macrofungi present in northwestern India. Keywords – banj oak – Basidiomycota – Boletaceae – ectomycorrhizal fungi – new taxa
Xerocomus garhwalensis A. Nautiyal, M. Ben Hassine Ben Ali & S. L. Stephenson, sp. nov. Etymology – the name refers to the region (Garhwal) in India where the type specimen was collected.  Xerocomus rishikeshinus A. Nautiyal, M. Ben Hassine Ben Ali & S. L. Stephenson, sp. nov. Etymology – the name refers to the largest city (Rishikesh) near the site in India where the specimen was collected.

| 8:29a | [Crustacea • 2015] Kingsleya castrensis • A New Species of Kingsleya (Decapoda: Pseudothelphusidae) from the Xingu River, southern Amazon Basin, Brazil
ABSTRACT Kingsleya castrensis sp. nov., a pseudothelphusid crab is described and illustrated from the Xingu River, state of Pará, southern Amazon region, Brazil. The new species is characterized by the male first gonopod bearing a large, well-developed apical plate, with a broadly rounded, thick distal lobe. New records of Kingsleya junki Magalhães, 2003 extend the distribution of this species eastward to the Tocantins River basin, in the state of Pará, Brazil. Key words: Amazon; Brachyura; Kingsleyini; Neotropical region; taxonomy
Kingsleya castrensis sp. nov. Diagnosis. G1 with large, roughly rounded, thick apical plate, widest medially; proximal lobe of apical plate subtriangular, well developed, situated on mesio-caudal side; distal margin straight, stretching diagonally over the distal lobe, fusing to mesiodistal portion of apical plate; distal lobe of apical plate broad, with lateral margin angulate in mesial view, caudal margin straight, distal margin slightly concave, mesial margin rounded, thick. Etymology. The specific epithet refers to castra, the Latin word for military camp, in reference to the Brazilian Army battalion camp where this species was found.

| 8:39a | [Crustacea • 2023] Chaceus guajiraensis • A New Species of Freshwater Crab of the Genus Chaceus Pretzmann, 1965 (Decapoda: Pseudothelphusidae) from La Guajira, Colombia
Abstract We describe and illustrate a new species of Chaceus Pretzmann, 1965, from the Regional Natural Park of the Serranía de Perijá, La Guajira Department, Colombia. This increases the number of Chaceus species to ten, three of them with records only from Venezuela. The species of this genus are distributed in the Sierra de Santa Marta of Colombia and the Serranía de Perijá of Colombia and Venezuela. We distinguished the new species from its congeners mainly by the third maxilliped, with an exopod that is 0.60–0.62 the length of ischium, and by the morphology of the first male gonopod, particularly by the shapes of the mesial, marginal, and lateral processes. We include the distribution of the Chaceus species here and a key for the identification of the species based on the morphology of the first male gonopod.

| 8:59a | [Botany • 2024] Microtropis gulinqingensis (Celastraceae) • A New dioecious Species from China
Abstract A new species of Celastraceae, Microtropis gulinqingensis, is discovered in the dynamic plot of Gulinqing Provincial Nature Reserve, Yunnan Province, China. After two-year observations of 65 individual plants in the field, we found that this species presented unique traits of being dioecious and having highly connate petals in its male flowers. We compared it with similar species and those in Microtropis distributed across the adjacent regions, and the morphological evidence supports the recognition of Microtropis gulinqingensis as a new species. A comprehensive description and photographs of this new species are provided.

| 2:19p | [Funga • 2024] Phaeoclavulina bicolor, P. echinoflava & P. jilinensis • Three New ramarioid Species of Phaeoclavulina (Gomphales: Gomphaceae) from China
Abstract Three new species of Phaeoclavulina from China are described: Phaeoclavulina bicolor, P. echinoflava, and P. jilinensis. Recognition of the new species is supported by morphological and molecular evidence. Phylogenetic analyses of concatenated ITS1–5.8S–ITS2 and nuclear large subunit sequences support the establishment of the new species and their placement within the Phaeoclavulina clade. A key to the known Phaeoclavulina species in China is provided. Key words: Morphological characters, phylogenetic analysis, Ramarioid fungi, taxonomy

| 2:57p | [Paleontology • 2025] Obelignathus septimanicus • Exploring the Diversity and Disparity of rhabdodontomorph Ornithopods from the Late Cretaceous European Archipelago
Abstract The origin and early diversification of ornithopods, a major clade of ornithischian dinosaurs, remain poorly understood, with conflicting phylogenetic hypotheses regarding rootward neornithischian relationships. Some topological stability is inferred near the basal divergence of Iguanodontia, though the ingroup relationships remain unclear. For instance, Rhabdodontidae, a clade of Late Cretaceous European ornithopods ‘traditionally’ considered to include eight to nine species, presents significant taxonomic challenges. We explore the diversity and disparity of European Rhabdodon-lineage iguanodontians. We assembled a novel dataset comprising morphological and morphometric data obtained from rhabdodontomorph dentaries, which are abundant, well-preserved in the majority of the taxa, and distinctive. Special attention is given to Rhabdodon septimanicus, a poorly known taxon from the upper Campanian to lower Maastrichtian of southern France, established based on a particularly robust dentary bone that has been subjected to conflicting taxonomic interpretations. Our restudy of the specimen, combined with a multivariate and phylogenetic assessment, shows that this taxon is a clear morphological outlier among European rhabdodontomorphs, providing a basis for its assignment to a new genus, Obelignathus. Although further large-scale studies, especially detailed osteological descriptions, are needed to clarify the taxonomic significance of certain European rhabdodontomorphs, our results indicate that the group exhibits greater diversity than currently recognized, with several sympatric taxa co-occurring, at least in southern France and possibly also in Romania.
