| 7:31a | [Funga • 2023] Xerocomellus perezmorenoi (Basidiomycota: Boletales: Boletaceae) • A New edible Species from Mexico
Abstract Xerocomellus perezmorenoi (Boletaceae, Boletales) is described as a new species from Mexico. This species was collected under Abies religiosa in mixed coniferous forest located in three localities (Puebla, Tlaxcala, and State of Mexico) in central Mexico. It is morphologically characterized by its small-sized basidiomata, pileus brown at the center and cream with pink to purple tones at the margin, almost blackish at the center when young, black-brown when mature, pores lilac, peach to salmon when young, yellow citrine at mature; violet or violet-brown color reaction of the context when cut; basidiospores (12–) 15–16 (–17) × 4–5 (–6) µm. Phylogenetic analyses (Maximum likelihood and Bayesian inference) based on multi-locus sequences confirmed X. perezmorenoi is a new species, with biocultural importance due to edibility. Detailed a description, photographs, analyses of phylogenetics, and taxonomic discussions are presented. Keywords: Fungi, Abies religiosa, boletes, central Mexico, ectomycorrhizal fungi

| 7:44a | [Funga • 2021] Updated Description of Atheniella (Agaricales: Mycenaceae), including Three New Species with brightly coloured pilei from Yunnan Province, southwest China
Abstract An updated description of the genus Atheniella, combining macro- and micromorphological characters that elaborate on the original generic characterisation, is presented. Atheniella is characterised by a brightly coloured pileus, all tissues inamyloid and pileipellis covered with simple to branched excrescences. Previously, nine Atheniella species were known globally, of which three species were accepted in China. Three newly-recognised species classified in the genus are here formally described from Yunnan Province: Atheniella flavida sp. nov., A. rutila sp. nov. and A. taoyao sp. nov. The new species are characterised by a yellow, orange, pink or red pileus, fusiform cheilocystidia and pleurocystidia, non-smooth pileipellis, stipitipellis smooth or with cylindrical ornamentation, caulocystidia fusiform or subglobose, if present and all tissues inamyloid. Morphological descriptions, photographs, line drawings and comparisons with closely-related taxa are presented for the new species. A phylogenetic analysis of sequence data for the rDNA internal transcribed spacer region and nuclear large ribosomal subunit (ITS + nLSU) supported that Atheniella is resolved as monophyletic and also supported the taxonomic recognition of the new species. A key to the 12 species of Atheniella is also provided. Keywords: new taxon, polygenes, taxonomy, white basidiospores

| 7:52a | [Botany • 2022] Erythroxylum austroguangdongense (Erythroxylaceae) • A New Species from Guangdong, China
Abstract Erythroxylum austroguangdongense (Erythroxylaceae), a new species from Guangdong Province, China, is described and illustrated. This new species is morphologically most similar to E. calyptratum, but is distinguished by the leathery leaf blade with fewer pairs of secondary veins and flowers borne on leafless nodes of the basal part of the current branch with much longer pedicels and sub-rectangular petal appendages. This is the second native species of Erythroxylum recorded from China. Keywords: Coca family, morphology, taxonomy
Erythroxylum austroguangdongense C. M. He, X. X. Zhou & Y. H. Tong, sp. nov. Diagnosis: Most similar to E. calyptratum Komada & Tagane in having reddish brown to grayish brown branches with dense lenticels, and white petals with appendages, but distinguished by the leathery (vs. thinly chartaceous) leaf blade with fewer pairs of secondary veins (6–8 pairs vs. 11–15 pairs), and flowers borne on leafless nodes of the basal part of current branch (vs. in leaf axils) with longer pedicels (1–1.5 cm vs. 5.2–7 mm) and sub-rectangular petal appendage (vs. bilobed appendage with each lobe consisting of a short anterior auricle and a large posterior auricle). A more detailed comparison of the two species is shown in Table 1. Etymology: The species epithet is named after the distribution area of this new species, South Guangdong. Vernacular name: 南粤古柯 (Chinese pinyin: nán yuè gŭ kē).  Chun-Mei He, Xin-Xin Zhou, Xue-He Ye, Weijun Chen and Yi-Hua Tong. 2022.

| 4:09p | [Herpetology • 2024] Cyrtodactylus phamiensis • A New Species of the Cyrtodactylus chauquangensis Group (Squamata: Gekkonidae) from the borderlands of extreme northern Thailand
Abstract Phylogenetic and morphological analyses delimit and diagnose, respectively, a new population of a karst-dwelling Cyrtodactylus from extreme northern Thailand. The new species, Cyrtodactylus phamiensis sp. nov., of the chauquangensis group inhabits karst caves and outcroppings and karst vegetation in the vicinity of Pha Mi Village in Chiang Rai Province, Thailand. Within the chauquangensis group, Cyrtodactylus phamiensis sp. nov. is the earliest diverging species of a strongly supported clade composed of the granite-dwelling C. doisuthep and the karst-dwelling sister species Cyrtodactylus sp. 6 and C. erythrops. The nearly continuous karstic habitat between the type locality of Cyrtodactylus phamiensis sp. nov. and its close relatives Cyrtodactylus sp. 6 and C. erythrops, extends for approximately 200 km along the border region of Thailand and the eastern limit of the Shan Plateau of Myanmar. Further exploration of this region, especially the entire eastern ~ 95% of the Shan Plateau, will undoubtably recover new populations whose species status will need evaluation. As in all other countries of Indochina and northern Sundaland, the continual discovery of new karst-dwelling populations of Cyrtodactylus shows no signs of tapering off, even in relatively well-collected areas. This only highlights the conservation priority that these unique karstic landscapes still lack on a large scale across all of Asia. Key words: Bent-toed gecko, genetics, Indochina, integrative taxonomy, karst, morphology
Cyrtodactylus phamiensis sp. nov. Diagnosis: Cyrtodactylus phamiensis sp. nov. can be separated from all other species of the chauquangensis group by the combination of having a maximum SVL = 74.4 mm (female); 8–12 supralabials; 9–11 infralabials; 30–43 paravertebral tubercles; 19–25 rows of longitudinally arranged tubercles; 29–37 longitudinal rows of ventrals; 6–9 expanded subdigital lamellae on the fourth toe; 12–14 unmodified subdigital lamellae on the fourth toe; 19–22 total subdigital lamellae on the fourth toe; 19–28 total number of enlarged femoral scales; 9–14 total number of femoral pores in males (n = 4); 6–11 enlarged precloacals; 4–6 precloacal pores in males (n = 4); two or three rows of large post-precloacal scales; enlarged femorals and enlarged ... Etymology: The species name phamiensis is in reference to the type locality at Pha Mi Village, Wiang Phang Kham Subdistrict, Mae Sai District, Chiang Rai Province, Thailand (Fig. 1). L.

| 4:16p | [Herpetology • 2024] Rhynchocalamus hejazicus • The Missing Piece of the Puzzle: A New and widespread Species of the Genus Rhynchocalamus Günther, 1864 (Squamata: Colubridae) from the Arabian Peninsula
Abstract Discovery rates of new species are uneven across taxonomic groups and regions, with distinctive and widely distributed species being more readily described than species with secretive habits. The genus Rhynchocalamus includes five species of secretive snakes distributed from Egypt eastwards to Iran, including the Arabian Peninsula. A wide biogeographic gap exists within the genus, which separates R. dayanae found in south Israel from R. arabicus, which occurs in the coastal areas of south Yemen and Oman. We describe Rhynchocalamus hejazicus sp. nov., a small, secretive snake, with a distinctive colouration and a melanistic morph. The new species occurs in the northwestern Hejaz region of the Kingdom of Saudi Arabia (KSA) and fills a large part of the existing distribution gap of the genus in the Arabian Peninsula. Molecular analyses of mitochondrial (12S, 16S, cytb) and nuclear genes (cmos, MC1R, NT3, RAG1) indicate that R. hejazicus sp. nov. is closely related to R. dayanae and R. arabicus, but uncertainty on the deep relationship within the genus remains. The new species has a large distribution range which potentially includes other regions in Jordan and KSA, and is associated with mountainous areas with cold wet seasons. Furthermore, it inhabits sandy and stony soils with varying vegetation cover and can be found in anthropogenically disturbed habitats, suggesting that the species should not be categorised as threatened according to IUCN criteria. The discovery of such a distinctive species highlights the existing gap in the description of rare and secretive species, and the need to enhance sampling efforts and monitoring strategies to fully capture species diversity in unexplored areas. Key Words: Biogeography, Colubrinae, Middle East, secretive species, Serpentes, species distribution model 
Rhynchocalamus hejazicus sp. nov. Diagnosis: The new species of Rhynchocalamus from the Hejaz Mountain range in western Saudi Arabia is characterised by the following morphological characters: (1) SVL 209.2–339.5 mm in adults; (2) tail length 38.3–64.2 mm in adults; (3) loreal scale present; (4) large 3rd and 4th upper labial scales in contact with the eye; (5) one preocular scale; (6) 1–2 postocular scales; (7) one temporal scale; (8) 0–2 post–temporal scales; (9) six upper labial scales; (10) eight lower labial scales; (11) usually four lower labial scales in contact with the anterior inframaxillars; (12) usually one gular scale in contact with ...  Etymology: The species name is a latinized noun in masculine gender derived from the word "Hejaz–" = Hejaz Mountains, a mountain range located in the Hejaz region (an important region located in western Saudi Arabia, where the two holy cities of Islam, Mecca, and Medina are located) where most individuals were observed, and the Latin suffix "–icus" = “belonging to”. We suggest the common name “Hejaz black–collared snake” in English and أبو حناء [Abu Henna] in Arabic for the new species. Fulvio Licata, Lukáš Pola, Jiří Šmíd, Adel A.

| 8:18p | [Entomology • 2021] Yagder serratus • A New eyeless Weevil from Mexico and the non-monophyly of Brachycerinae, the Evolutionary Twilight Zone of True Weevils (Coleoptera: Curculionidae)
Abstract We describe and illustrate a new eyeless weevil, Yagder serratus gen. & sp. nov., based on a single adult female collected by sifting forest leaf litter in Mexico. A phylogenetic analysis of 39 terminals and 2679 aligned positions from three DNA fragments places the new species into the subfamily Brachycerinae (as incertae sedis) and outside the highly diversified clade of ‘higher’ true weevils. Neither Brachycerinae, nor its tribe Raymondionymini traditionally uniting most eyeless weevils, are monophyletic unless the latter is limited to a Mediterranean core group. Both these taxa are taxonomic dumping-grounds likely containing species-poor sisters of species-rich clades. When resolved, the subfamily Brachycerinae will be likely split into two or more species-poor deeply-divergent subfamilies. Key words: Coleoptera, DNA barcode, ITS2, 28S, phylogeny, forest litter, species discovery 
Yagder gen. nov. Yagder serratus sp. nov. Diagnosis. This genus can be recognized among all weevils (Curculionoidea, including true weevils Curculionidae) by the combination of the following characters: eye completely absent; body size larger, 3.8 mm in length (excluding rostrum and deeply inserted head), slender (ratio of length to maximal width 2.9) and parallel-sided in ... Etymology. The generic name is a meaningless combination of letters; its gender is masculine; . The species name is the Latin adjective meaning “serrated, toothed like a saw”. Vasily V.
