| 3:48a | [Entomology • 2020] Vietomartyria wuyunjiena & V. maoershana • Two New Vietomartyria Species (Lepidoptera: Micropterigidae) from China
Abstract Micropterigidae is a family of Lepidoptera characterized by plesiomorphic morphological characters. Presently, this family consists of more than 22 genera and is distributed throughout all biogeographic realms. Vietomartyria Hashimoto & Mey, 2000 presently consists of six species mainly from South China. Two new species of the genus, V. wuyunjiena sp. nov. and V. maoershana sp. nov., are described herein from China; adult genitalia and wing venation are illustrated. Some biological accounts of the new species are also provided. A key to all described Vietomartyria species is given. Keywords. Micropterigidae, Vietomartyria, new species, morphology, taxonomy. Class Insecta Linnaeus, 1758 Order Lepidoptera Linnaeus, 1758 Superfamily Micropterigoidea Herrich-Schäffer, 1855 Family Micropterigidae Herrich-Schäffer, 1855
Micropterigidae Vietomartyria wuyunjiena sp. nov. Diagnosis: The adults of this species are very similar to Vietomartyria nankunshana Hirowatari & Hashimoto, 2009 and V. nanlingana Hirowatari & Jinbo, 2009 because of their same ground color, but are separable from these two species by the dorsal process of the valva slightly curved inwardly (but almost right-angularly curved inwardly in V. wuyunjiena sp. nov.), and by tergite X slightly emarginate at the middle (but broadly emarginate in V. nankunshana and narrowly in V. nanlingana). Etymology The specific epithet is derived from the name of the type locality, Wuyunjie National Nature Reserve. Distribution This species is known from Wuyunjie National Nature Reserve (Taoyuan, Changde, Hunan, China). Vietomartyria maoershana sp. nov. Diagnosis This species is very similar to V. wuyunjiena sp. nov. and V. expeditionis, but can easily be distinguished by the following characters: paired X tergal lobes slender and digitate (slightly emarginate in V. wuyunjiena sp. nov. and broadly emarginate at the middle in V. expeditionis); basal process of valva long and pointed (absent in V. wuyunjiena sp. nov. and short obtuse in V. expeditionis); slightly curved dorsal process of gonopod (strongly curved in V. expeditionis). Etymology This specific epithet is derived from the name of the type locality, Mao’ershan National Nature Reserve. Distribution This species is known from Mao’ershan National Nature Reserve (Xin’an, Guilin, China). Remarks Adults of V. maoershana sp. nov. were collected along a paved road at 1500 m a.s.l., half way up Mt Mao’ershan. Similar to V. wuyunjiena sp. nov., the adults were observed flying or perching on low shrubs and ferns in cloudy conditions and even in weak rainfall. Liao C.Q., Hirowatari T. and Huang G.H. 2020.

| 8:40a | [Botany • 2025] Sageraea multiovulata • Molecular Phylogenetic Analyses of Winitiinae (Annonaceae) shed light on the Evolution of Floral Sex, with A New Species of Sageraea from southern Thailand
Abstract Molecular phylogenetic inferences of the recently described subtribe Winitiinae (consisting of Sageraea, Stelechocarpus and Winitia), which belongs to the tribe Miliuseae of the pantropical family Annonaceae, have been performed using seven plastid DNA regions (matK, rbcL, ndhF and ycf1 exons; trnL intron; psbA-trnH and trnL-trnF intergenic spacers) and including, among others, almost all species of Sageraea, the only species of Stelechocarpus and all species of Winitia. The phylogenetic results corroborate the erection of Winitiinae and a detailed description of the subtribe is given. Moreover, Sageraea elliptica appears paraphyletic and should be reclassified, awaiting detailed morphological reinvestigations. In addition, ancestral state reconstructions of floral sex, with the emphasis on Winitiinae, have been carried out. The results indicate that in Winitiinae two independent shifts from bisexual flowers to unisexual flowers have occurred. Further, Sageraea multiovulata, a new species from Surat Thani Province, southern Thailand is described, illustrated and compared with its congeners. It belongs in a clade with two other species: S. lanceolata and S. sarawakensis, but the relationships in this clade are unresolved. The new species occurs in a unique habitat, i.e., near the shore of Tapi River, with inundation for c. 6 months. The conservation status of S. multiovulata is provisionally assessed as Critically Endangered. Keywords: Magnoliids, Malmeoideae, Molecular phylogenetics, Morphology, Systematics, Taxonomy

| 9:01a | [Botany • 2024] Hechtia cerrostlatilpae (Bromeliaceae: Hechtioideae) • A New Species from Morelos, Mexico
Abstract Background: As a result of botanical explorations carried out for the project Bromeliaceae of Mexico, we collected plants of the genus Hechtia within the Sierra de Huautla Biosphere Reserve, in Xochipala, municipality of Tlaquiltenango, Morelos, Mexico. However, this plant does not resemble any known species. Question: Do the Hechtia populations in Xochipala correspond to an undescribed taxon? Studied species: Species of Hechtia previously reported from Morelos and all the taxa with greater morphological similarity to the new proposed taxon. Study site and date: Xochipala, municipality of Tlaquiltenango, Morelos, Mexico, 2023. Methods: Our research involved field work, review of herbarium specimens, protologues, and type material of all the species of Hechtia distributed in Morelos, in the neighboring states of Puebla and Guerrero, and of the most morphologically similar taxa. Results: After a careful and detailed review of the living material and herbarium specimens, we conclude that those plants belong to an undescribed taxon that we propose here. A morphological description, images, and a distribution map of Hechtia cerrostlatilpae are included, as well as an identification key and a list of examined specimens of all Hechtia species known from the state of Morelos. Conclusions: The discovery of a new species of Hechtia in Xochipala, Morelos, Mexico increases the plant diversity of Morelos, particularly at the Sierra de Huautla Biosphere Reserve. Hechtia cerrostlatilpae presents unique vegetative and floral characters that allow its recognition as a new species within the genus. Keywords: Balsas Basin, Monocots, Poales, saxicolous, Sierra de Huautla Biosphere Reserve
Hechtia cerrostlatilpae Hern.-Cárdenas, Espejo & López-Ferr., sp. nov. Diagnosis. The new species is similar to Hechtia medusae Hern.-Cárdenas, Siekkinen, López-Ferr. & Espejo (Hernández-Cárdenas et al. 2020) but differs in the arrangement of the staminate and pistillate inflorescences (twice branched vs. once branched), in the number of primary branches in staminate inflorescences (10-15 vs. 20-25), in the shape of staminate floral bracts (widely ovate vs. triangular to ovate), and in the shape of petals of the pistillate flowers (triangular vs. ovate). Etymology. The specific epithet honors Dra. Rosa Cerros Tlatilpa, botanist colleague and friend, who has made significant contributions to the knowledge of the flora and vegetation of the state of Morelos and the Sierra de Huautla region, where the new species grows.

| 10:16a | [Botany • 2025] Potentilla sanczirii (Rosaceae) • A New Species from high Mountain Range in Western Mongolia
Abstract The genus Potentilla L. is one of the genus with controversial taxonomic position in family Rosaceae, and show a rich species diversity, adapting in mountains hills, high-altitude mountains and arid communities in Palearctic region. Potentilla sanczirii is described and illustrated as new species from Western Mongolian high mountain range. We used conventional morphometric and molecular phylogeny methods to describe new species. With this new contribution, we added a species to the genus Potentilla. L, which makes it with 79 elements in Mongolia. It is morphologically similar to P. nivea, such as, basal leaves ternate, Lower leaflet surface covered with whitish or grayish tomentose. However, differs in multiple caudex covered with dark-brown remains of decayed stipules, and the upper surface of its leaves is adorned with long, silky hairs (light grey). This species' mature nuts (achenes) are light green, approximately 1.0 mm long, and have a smooth surface.A Bayesian Inference tree was reconstructed to further understand the phylogenetic relationships within the genus, and a time-calibrated phylogenetic tree of the subtribe Potentillinae, including 15 species of Pot entilla from Mongolia. The time-calibrated phylogenetic tree suggests that the newly discovered P. sanczirii originated approximately 6.50 million years ago during the late Miocene.

| 4:56p | [PaleoIchthyology • 2025] Pararhincodon torquis • Three-dimensional Fossils of a Cretaceous Collared Carpet Shark (Orectolobiformes: Parascylliidae) shed light on Skeletal Evolution in galeomorphs
Abstract A rich fossil record of teeth shows that many living shark families’ origins lie deep in the Mesozoic. Skeletal fossils of the sharks to whom these teeth belonged are far rarer and when they are preserved are often flattened, hindering understanding of the evolutionary radiation of living shark groups. Here we use computed tomography to describe two articulated Upper Cretaceous shark skeletons from the Chalk of the UK preserving three-dimensional neurocrania, visceral cartilages, pectoral skeletons and vertebrae. These fossils display skeletal anatomies characteristic of the Parascylliidae, a family of Orectolobiformes now endemic to Australia and the Indo Pacific. However, they differ in having a more heavily mineralized braincase and a tri-basal pectoral fin endoskeleton, while their teeth can be attributed to a new species of the problematic taxon Pararhincodon. Phylogenetic analysis of these new fossils confirms that Pararhincodon is a stem-group parascylliid, providing insight into the evolution of parascylliids’ distinctive anatomy during the late Mesozoic–Cenozoic shift in orectolobiform biodiversity from the Northern Atlantic to the Indo Pacific. Meanwhile both Pararhincodon and extant parascylliids have a distinctive vertebral morphology previously described only in Carcharhiniformes, contributing a skeletal perspective to the picture emerging from macroevolutionary analyses of coastal, small-bodied origins for galeomorphs.
