| 4:24a | [Botany • 2022] Cymbidium ×shangrilaense (Orchidaceae: Epidendroideae) • A New natural hybrid from Yunnan, China: evidence from morphology and molecular analyses
Abstract A new natural hybrid of Cymbidium (Orchidaceae), C. ×shangrilaense, from Yunnan Province, China, is illustrated and described. This entity may be a natural hybrid between C. tracyanum and C. gaoligongense. Morphologically, it differs from former by epidermal stripes and column and lip midlobe morphology and from the latter by its flower veins and lip morphology. Molecular analysis based on nuclear (ITS) DNA clearly indicated a relationship of the natural hybrid to group of Cymbidium species, whereas the plastid DNA (matK and rbcL) tree confirmed the natural hybrid as sister to C. tracyanum, C. subgenus Cyperorchis.

| 7:57a | [PaleoIchthyology • 2021] Jiangxialepis retrospina • The Oldest eugaleaspiform (Galeaspida) from the Silurian Fentou Formation (Telychian, Llandovery) of Wuhan, South China
Abstract A new genus of Eugaleaspidiformes (Galeaspida, Agnatha), Jiangxialepis gen. nov., is described from the Llandovery (Silurian) Fentou Formation from Wuhan, Hubei, South China. The new genus belongs to the family Shuyuidae, as evidenced by the splayed posterior supraorbital canals, absence of ‘U’-shaped median dorsal canals, and three lateral transverse canals issuing from the infraorbital canals. The new genus possesses a middle dorsal spine, which is found in eugaleaspidiforms for the first time. Jiangxialepis differs from other genera of Shuyuidae based on the following characteristics: presence of a middle dorsal spine, the anterior end of the median dorsal opening slightly disrupting the rostral margin of the head shield, large oval orbital openings, pineal opening level with the centre of the orbital opening, and seven lateral transverse canals on each side. The new genus is the first discovery of a eugaleaspidiform in the Fentou Formation, which extends the age of eugaleaspiforms to the middle Telychian and illuminates the early morphological conditions of the Eugaleaspidiformes. Cladistic analysis shows that the new genus is the most primitive group of Eugaleaspidiformes (Shuyuidae) and forms a trichotomy with Shuyu and Meishanaspis. We interpret Jiangxialepis as a sub-demersal fish that lived in the brackish waters of an estuarine-deltaic environment.

| 9:14a | [Botany • 2025] Kaempferia chonburiensis (Zingiberaceae) • A New Species from Thailand based on morphological and molecular evidence
Background Kaempferia is a genus belonging to the ginger family. Currently, this genus is comprised of about 63 species, mainly distributed from India to Southeast Asia. During our fieldwork, a new species of Kaempferia was found in Chon Buri Province, Thailand. The objective of this article was to provide morphological evidence and confirm its relationships in Kaempferia through molecular phylogenetic analysis. Methods: Plant samples were collected from field sites and investigated by conventional taxonomy and molecular techniques. The phylogenetic trees were reconstructed using the maximum likelihood criterion and Bayesian inference. The morphological evolution was also examined to elaborate the relationships among representative Kaempferia taxa. Results: Kaempferia chonburiensis from southeastern Thailand is described and illustrated based on morphological features and its taxonomic placement was confirmed by molecular phylogenetic analyses and morphological evolution. An identification key is provided for the new Kaempferia species occurring in Thailand. Conclusion: Kaempferia chonburiensis is a new enumerated species of Kaempferia from Thailand.
Kaempferia chonburiensis Picheans., Sukrong & Wongsuwan, sp. nov. Diagnosis: This new species is similar to Kaempferia koratensis, but differs in the following characters: (1) longer ligule (0.6–1 cm vs. ca. 3 mm), (2) longer peduncle (0.8–1.2 cm long vs. ca. 5 mm long), (3) glabrous bract, (4) white with yellow spot at the base, with or without violet patch on labellum, (5) pubescent at the uppermost part of ovary.  Etymology: The specific epithet ‘chonburiensis’ refers to the province of the type locality. Vernacular name: Pro (เปราะ), Wan Pro (ว่านเปราะ), Pro Mueang Chon (เปราะเมืองชล).

| 3:02p | [Botany • 2025] Lepanthes luicitae & L. salvaterrae (Orchidaceae: Pleurothallidinae) • Two New Species, Nomenclatural Notes and An updated Checklist in Lepanthes from Mexico
Abstract Two new orchid species from Mexico are described and illustrated here: Lepanthes luicitae, from the mountains of northern Oaxaca, and Lepanthes salvaterrae, from central Veracruz. Lepanthes luicitae is similar to L. thurstoniorum from which differs by its flexuous rachis (vs. zigzag), dorsal sepal as wide as the lateral ones (vs. lateral sepals almost 2/3 the width of the dorsal one), lateral sepals obliquely ovate and diverging from each other towards their apices (vs. obliquely triangular-ovate and subparallel to each other towards their apices), and petals forming butterfly wing-like blades (vs. forming oblong and oblique blades). Meanwhile, L. salvaterrae is similar to L. gabriellae but differs in having a peduncle shorter than the leaf (vs. equal or longer than the leaf), orbicular to orbicular-elliptic leaves (vs. narrowly elliptic), marginally glabrous sepals (vs. with reddish cilia), and petals with upper and lower lobes different in shape and size (vs. similar to each other). Lepanthes acuminata subsp. ernestii, is elevated to specific status, and it is reported for the first time for the Mexican states of Oaxaca and Veracruz, and for Guatemala. Meanwhile, L. machorroi and L. papilionacea are reported as new records for the flora of Veracruz. The richness of Lepanthes in Mexico has increased to 68 species, 39 of which have a distribution restricted to the country. Finally, an updated checklist, including accepted and synonym names for Lepanthes of Mexico, is present here. checklist, Lepanthes ernestii, Lepanthes luicitae, Lepanthes salvaterrae, Mexican endemisms, Monocots   Lepanthes luicitae Solano   Lepanthes salvaterrae Solano, J.R.

| 3:11p | [Entomology • 2024] Zimmiodes australis & Z. papuanus • An Integrative Taxonomic and Phylogenetic Approach reveals A New Genus of Australasian Cycas-pollinating Weevils (Coleoptera: Curculionidae: Cossoninae)
Abstract Cycas is the second-largest genus of cycads in Australia and the sole cycad genus in Papua New Guinea. In contrast to the other Australian cycads, which are mainly pollinated by weevils of the Tranes group of Molytinae, the Australian Cycas species are pollinated by tiny weevils belonging to the subfamily Cossoninae but representing an unnamed genus. This study evaluates the taxonomic status of these weevils by combining morphological examination with molecular phylogenetic analyses and species delineation based on mitochondrial DNA. The results reveal that the Cycas-pollinating weevils in Australia comprise only one species, here described as Zimmiodes australis gen. et sp. nov., with another species in Papua New Guinea, described as Zimmiodes papuanus sp. nov. The phylogenetic analyses and morphological comparison reveal that Zimmiodes belongs in the tribe Pentarthrini of Cossoninae and that the related Tychiodes group includes not only Tychiodes Wollaston, Tychiosoma Wollaston and Nanoplaxes Heller but also Tyrpetes Heller and is also assignable to Pentarthrini. The conspecificity of Zimmiodes weevils from all Australian Cycas species sampled suggests the likely taxonomic oversplitting of the Australian Cycas species and thus provides new insights into the taxonomy of the Australian cycads.
