| 3:21a | [Mollusca • 2020] Imeretiopsis gen. nov., Caucasopsis gen. nov., Caucasogeyeria colchis, C. chrysomallos, Imeretiopsis prometheus, Kartvelobia sinuata, Hausdorfenia shareula, ... • The Phylogeny of stygobiotic Sadlerianinae Szarowska, 2006 (Gastropoda: Hy
Abstract The position of the southwestern Caucasus as a stygobiotic Mollusca hotspot is confirmed. Molecular data of stygobiotic gastropods revealed the diversity of subfamily Sadlerianinae Szarowska, 2006, inhabiting the subterranean environment of Georgia. In addition to the well-known endemic genera Pontohoratia Vinarski, Palatov & Glöer, 2014 and Motsametia Vinarski, Palatov & Glöer, 2014, five more genera were identified in northwestern Georgia as new to the science: Kartvelobia gen. nov., Imeretiopsis gen. nov., Caucasopsis gen. nov., Caucasogeyeria gen. nov., and Hausdorfenia gen. nov. Additionally, 21 new species were found to inhabit the studied area (Samegrelo, Imereti, Racha regions in Georgia).

| 3:31a | [Invertebrate • 2025] Salina aurantiamaculata & S. pseudomontana • Two New Species of Salina MacGillivray (Collembola: Entomobryidae), with Descriptive Notes on Two endemic Species from India
Abstract Two new species of the genus Salina MacGillivray are herein described in detail. The bright orange color pattern of Salina aurantiamaculata sp. nov. and its chaetotaxy distinguish it from other species of the genus. Salina pseudomontana sp. nov. shares similarities with Salina (Salina) montana (Imms) and Salina (Salina) yosiii Salmon in color pattern, though the new species differs in chaetotaxy from the latter one. Two endemic species from India, Salina (Salina) quattuorfasciata (Handschin) and Salina (Salina) striata (Handschin) have their original descriptions improved, with additions to their morphology, especially their chaetotaxy. Finally, we also provide an identification key comprising the known species of Salina recorded from India.

| 4:14a | [Botany • 2025] Sedum shunhuangense (Crassulaceae) • A New Species from Hunan, China
Abstract We describe and illustrate Sedum shunhuangense, a new species from Hunan, China. The species is morphologically similar to S. alfredii and S. yangjifengensis but differs in having subequal sepals, papillate seeds, and alternate leaves with caducous lower leaves during flowering. Phylogenetic reconstruction strongly supports two accessions of S. shunhuangense as monophyletic and sister to S. lipingense and S. wilsonii. The species has an estimated wild population of 200 individuals and is assessed as Endangered (EN) under IUCN criteria. Key words: Hunan Province, molecular phylogenetics, morphology, new species, Sedum
Sedum shunhuangense L.Wu & Z.L.Feng, sp. nov. Diagnosis. Phylogenetic analyses (Fig. 2) reveal that S. shunhuangense forms a sister group with S. lipingense and S. wilsonii. However, this species can be obviously distinguished from its allied species by the upper leaves aggregated at the flowering stem apex to form inflorescence bracts. Notably, S. shunhuangense shows distant phylogenetic relationships with S. alfredii and S. yangjifengensis; convergent evolution is observed in their phenotypic traits, particularly in inflorescence architecture and leaf morphology. However, it can be unequivocally distinguished by the following combination of characters (Table 1): (1) subequal sepals (vs. markedly unequal in both S. alfredii and S. yangjifengensis); (2) papillate seed coat (vs. smooth in S. alfredii); and (3) alternate leaves with caducous basal leaves during anthesis (vs. opposite leaves with persistent lower leaves in S. yangjifengensis). Etymology. Sedum shunhuangense L.Wu & Z.L.Feng, with the epithet derived from its type locality, Shunhuang Mountain. The nomenclature follows the International Code of Nomenclature for Algae, Fungi, and Plants (Turland et al. 2018), with holotype and paratype specimens permanently deposited.

| 4:56a | [Paleontology • 2025] Ueloca colemanorum • A New Leatherback Marine Turtle from the lower Oligocene of North America and A Phylogenetic Nomenclature for Dermochelyidae
Abstract The modern leatherback sea turtle Dermochelys coriacea possesses a unique, flexible mosaic carapace adapted for deep diving. The evolutionary origins of this structure remain poorly understood because of the fragmentary nature of the fossil record. Here we describe Ueloca colemanorum n. gen. n. sp., a novel ridgeless leatherback turtle from the lower Oligocene Glendon Limestone of Alabama, USA. This specimen (MSC 49490) represents one of the most complete fossil leatherback carapaces known and provides new insight into dermochelyid diversity and shell evolution. The carapace is composed of parallel rows of enlarged ossicles interspersed with smaller ossicles arranged in distinctive floriform patterns. Histological analysis reveals a cancellous core with an external cortex but no basal cortex, a condition also observed in Dermochelys coriacea. Phylogenetic analysis places Ueloca within a clade of ridgeless leatherbacks (Uelocini), which diverged from ridge-bearing Dermochelyini in the Eocene. Our revised phylogeny suggests that Uelocini and Dermochelyini represent the two main lineages of dermochelyines, both characterized by mosaic carapaces that undergo parallel morphological trends. These findings clarify the deep history of leatherback shell evolution and emphasize the need for additional well-preserved fossils to further refine dermochelyid systematics. KEYWORDS: Dermochelys, Glendon Limestone Member, Gulf Coastal Plain, North America
Dermochelyinae Weems, 1988 Uelocini new clade Ueloca new genus Etymology: The generic name, Ueloca (pronounced Wee-low-juh), is a Mvskoke (Creek) name derived from the Mvskoke words “Uewv” for water and “Loca” for turtle. This name honors the indigenous people of southern Alabama and serves as recognition of the contributions of Poarch Creek Indian tribal members to this project. Ueloca colemanorum n. gen. n. sp. Ueloca colemanorum new species Etymology: The species name, colemanorum, honors the Coleman family (Adrienne, Adam, Talah, and Corey) of Mobile, Alabama, who discovered MSC 49490 and then dedicated an extraordinary amount of time, energy, and resources to its recovery. Holotype: MSC 49490. Occurrence: Site AMo-10, Monroe County, AL, USA. Lower Oligocene (Rupelian) Glendon Limestone Member of the Byram Formation (NP 22, 33–32 Ma). Diagnosis: Ueloca colemanorum can be differentiated from most dermochelyids by an absence of carapacial ridges and by having a carapace with parallel, anteroposteriorly oriented rows of enlarged ossicles and clusters of ossicles arranged in floriform or ‘sunflower’ patterns. U. colemanorum. can be distinguished from other ridgeless dermochelyids with floriform ossicle patterns (Ca. rupeliensis and N. peruvianus) by having unsculptured ossicles that regularly exceed 4 cm in length, that are not associated with either floriform patterns or rows of enlarged ossicles, lacking deeply interdigitating ossicle sutures, and having central ossicles of floriform patterns which are only moderately scalloped.

| 3:11p | [Arachnida • 2021] Conothele isan, Latouchia maculosa, ... • Four New Trapdoor Spider Species in the Subfamily Ummidiinae (Araneae: Mygalomorphae: Halonoproctidae) from Thailand
Abstract Males and females of four mygalomorph spider species (family Halonoproctidae, subfamily Ummidiinae) are newly described from Thailand, and the taxonomy of Ummidiinae is discussed. This is the first time that trapdoor spider species in this subfamily are described from Thailand. Two of these new species belong to the genus Conothele, the other two species are placed in the genus Latouchia. Conothele martensi spec. nov. was found in the north of the country (Chiang Mai Province), C. isan spec. nov. and Latouchia incerta spec. nov. were collected in northeastern Thailand (Buri Ram Province, Surin Province and Roi Et Province), and L. maculosa spec. nov. was found in the southern coastal province of Prachuap Khiri Khan. Keywords: Araneae, Asia, Conothele, Latouchia, taxonomy, arachnology, morphology, natural history
