| 3:45a | [Botany • 2024] Phalaenopsis zhanhuoensis (Orchidaceae: Vandeae) • A New Species from Yunnan, China
Abstract A new species of Orchidaceae, Phalaenopsis zhanhuoensis, from Xichou County, Yunnan, China, is described and illustrated. The novelty is close to P. taenialis, P. wilsonii, and P. stobartiana, but differs from them by having a distinct, fleshy anterior callus with a deeply lobed apex at the base of the labellum and lateral lobes of labellum reflexed and facing outward. Key words: China, new species, Phalaenopsis zhanhuoensis, Xichou County, Yunnan
Phalaenopsis zhanhuoensis X.H.Jin & S.Y.Qin, sp. nov. 吉氏蝴蝶兰 Diagnosis: Phalaenopsis zhanhuoensis is similar to P. wilsonii, but differs from it by having a bifurcated yellow, fleshy anterior callus, lateral lobes with large calli and flipping outward (Table 1). Etymology: The epithet zhanhuoensis was designated in honor of the Chinese botanist Zhanhuo Tsi. Shiyu Qin, Hanchen Wang, Yajun Wang, Chongbo Ma, Zan Li, Boyun Yang and Xiaohua Jin. 2024. Phalaenopsis zhanhuoensis (Orchidaceae, Vandeae), A New Species from Yunnan, China. PhytoKeys. 237: 153-160. DOI: 10.3897/phytokeys.237.112270 | ||||||
| 6:49a | [Mollusca • 2021] Landouria circinata, L. elegans, L. trochomorphoides, etc. • Five New Species of the Land Snail Genus Landouria Godwin-Austen, 1918 (Gastropoda: Camaenidae) from northeastern Thailand, with Note on Genitalia and Radula Morphology of Land
ABSTRACT Five new species of the terrestrial snail genus Landouria Godwin-Austen, 1918 (Camaenidae) are described from northeastern Thailand, based on shell features, radular morphology, genital anatomy, and DNA sequence data: Landouria circinata sp. nov., L. tuberculata sp. nov., L. trochomorphoides sp. nov., L. chloritoides sp. nov., and L. elegans sp. nov. These species are phylogenetically well separated from each other by mtDNA phylogeny and COI sequence divergences of 0.073–0.156. The record of Thaitropis Schileyko, 2004 (currently synonymized with Landouria) in Thailand is re-interpreted as referring to L. diplogramma (Möllendorff, 1902) comb. nov. Keywords: Camaenidae, Landouria, Thailand, systematics, phylogeny

| 9:02a | [Arachnida • 2022] Liphistius hatyai, L. inthanon, L. keeratikiati • Three New Species of the Spider Genus Liphistius (Araneae: Mesothelae: Liphistiidae) from Thailand
Abstract We diagnose and describe three new species of the primitively segmented spider genus Liphistius from Thailand, based on male palp and female genital morphology: L. hatyai Zhan & Xu, sp. nov. (♂♀), L. keeratikiati Zhan & Xu, sp. nov. (♂♀), and L. inthanon Zhan & Xu, sp. nov. (♂♀). The classification of the three new species of Liphistius is discussed: L. hatyai sp. nov. and L. keeratikiati sp. nov. are assigned to the trang-group, and L. inthanon sp. nov. is placed in the bristowei-group according to male palp and female genital morphology. Keywords: Morphology, Southeast Asia, taxonomy, trapdoor spiders
Taxonomy Family Liphistiidae Thorell, 1869 Subfamily Liphistiinae Thorell, 1869 Genus Liphistius Schiødte, 1849 Type species: Liphistius desultor Schiødte, 1849. Distribution: China (Yunnan Province), Indonesia (Sumatra), Laos, Peninsular Malaysia, Myanmar, and Thailand. Liphistius hatyai Zhan & Xu, sp. nov. Etymology: The species epithet “hatyai” refers to the location of the type locality in Hat Yai District. Distribution: Southern Thailand (Songkhla Province) (Fig. 2). Liphistius inthanon Zhan & Xu, sp. nov. Etymology: The species epithet “inthanon” is a toponym referring to the type locality, Doi Inthanon National Park. Distribution: Northern Thailand (Chiang Mai Province) (Fig. 2). Liphistius keeratikiati Zhan & Xu, sp. nov. Etymology: The specific name is dedicated to Mr Kaweesak Keeratikiat for providing information on the locality of the species. Distribution: South-central Thailand (Chumphon Province) (Fig. 2).

| 9:16a | [Botany • 2024] Hedysarum qilianshanense (Fabaceae: Hedysareae) • A New Species from the Qilianshan Mountains in Gansu, China
Abstract Hedysarum qilianshanense sp. nov. (Fabaceae, Hedysareae) is described and illustrated from the Qilianshan Mountains in Gansu, China. This new species is similar to H. przewalskii, but can be distinguished by its corolla being light purple to purple, standard 15–19 mm long, wings 14–16 mm long, keels 16–19 mm long, and the ovary and legume being glabrous. The new species can be easily distinguished from H. neglectum Ledeb. by its bract being shorter than the pedicel, and the ovary and legume being glabrous. Phylogenetic tree based on the nuclear ITS and ETS sequences shows that H. qilianshanense is sister to H. przewalskii, while the tree based on the plastid psbA-trnH, trnC-petN, trnL-F, trnS-G and petN-psbM sequences shows H. qilianshanense as sister to a clade consisting of H. hedysaroides, H. inundatum, H. americanum and H. neglectum. The new species is a diploid with the chromosome number 2n = 14. Based on morphological, phylogenetic and karyotypic evidence, the new species may originate from an ancient homoploid hybrid speciation event. Key words: Karyotype, phylogeny, Qinghai-Tibetan Plateau, taxonomy
Hedysarum qilianshanense P.L.Liu, sp. nov. (H. sect. Hedysarum) Diagnosis: This new species is morphologically similar to H. przewalskii, but can be distinguished by its light purple to purple corolla (vs. light yellow to yellow corolla), 15–19 mm long standard (vs. 10–14 mm long standard), 14–16 mm long wings (vs. 10–14 mm long wings), 16–19 mm long keels (vs. 12–17 mm long keels), and glabrous ovaries and legumes (vs. often pubescent, sometimes glabrate or glabrous ovaries and legumes). The new species can be easily distinguished from H. neglectum by its bract shorter than pedicel (vs. bract longer than pedicel), and glabrous ovaries and legumes (vs. pubescent ovaries and legumes) (Table 2). Distribution and habitat: Hedysarum qilianshanense is only known from Su’nan, Gansu, China. It grows in stony slope and forest edge in valley, 2053–3000 m a. s. l. Etymology: The epithet qilianshanense is transliterated from the type location, Qilianshan Mountains in China. The Chinese vernacular name for this new species is 祁连山岩黄耆 (qí lián shān yán huáng qí).
