| 7:55a | [Funga • 2024] Cyathus magnipilosus (Basidiomycota: Nidulariaceae) • A New Species from Kalimantan, Borneo
Abstract In this study, we present the first new species of Cyathus from Indonesia. Cyathus magnipilosus is characterized by having light-colored basidiomata, an exoperidium with long tomentum, single-layered cortex, black peridioles with a smooth surface and elongated basidiospores. The new species is presented with morphological illustrated description, and phylogenetic analyses using ITS and LSU sequences. Cyathus magnipilosus fits in the pallidum group, based on recent classifications. Comparative analyses with related taxa and a detailed discussion are provided as well as an identification key to the known species of Cyathus in the pallidum group for the world. biodiversity, bird's nest fungi, new taxa, phylogeny, systematics, Fungi  Jefferson Dos Santos GÓIS, Rhudson Henrique Santos Ferreira da CRUZ, Iuri Goulart BASEIA and Kentaro HOSAKA. 2024.

| 8:00a | [Botany • 2024] Henckelia davidwoodii (Gesneriaceae) • A New Species from Indian eastern Himalayas
Abstract Henckelia davidwoodii (Gesneriaceae) is described here as a new species based on collections made from the Shi-Yomi district in the eastern Himalayan state of Arunachal Pradesh, India. This new species resembles H. lallanii Taram, D.Borah, Tag and R.Kr. Singh in its habit, infundibuliform corolla without flaps or flanges, and stamens with slightly geniculate filaments, but it can be differentiated by having 2-flowered cymes (versus solitary in H. lallanii), ovate bracts with undulate margins (versus narrowly ovate-lanceolate bracts with entire margins in H. lallanii), non-reflexed 5-veined calyx lobes (versus reflexed calyx lobes without veins in H. lallanii), and a cupular disc (versus tubular in H. lallanii). It also superficially resembles H. urticifolia (Buch.-Ham. ex D.Don) A.Dietr., however, it can be differentiated by its distinct sessile to sub-sessile bracts with undulate margins and a round to cordate base, often recurved at the base and overlapping to form a conical to cupulate structure, and stamens that are slightly geniculate (versus bracts with serrate margins and cuneate bases, never forming the aforementioned structures; stamens distinctly geniculate in H. urticifolia). A detailed taxonomic description is provided for this new species, accompanied by photographs and ecological information.

| 8:01a | [Ichthyology • 2024] Kapuasia, A Genus Name for ‘Nemacheilus’ maculiceps (Teleostei: Nemacheilidae) from the Kapuas Drainage on Borneo
Abstract Kapuasia, new genus, is created to accommodate ‘Nemacheilus’ maculiceps, from the Kapuas drainage on Borneo. It is distinguished by the presence of a large suprapectoral flap above the pectoral fin, and its unique lip morphology. The lower lip has a continuous anterior edge, and its median part has 8–10 ridges on each side, radiating at the anterior extremity, across the whole lip, resulting in a crenulated inner edge of the lip.

| 8:03a | [Entomology • 2024] Lulavia mahwii, Idaea medianocturna walaila & Protorhoe drechseli nebuloides • New geometrid Moths (Lepidoptera: Geometridae: Sterrhinae, Larentiinae) from Iraqi Kurdistan
Abstract A large number of geometrid moths was collected by the first author in Iraqi Kurdistan including several undescribed species and subspecies. In this paper we describe three new geometrid taxa: Idaea medianocturna walaila ssp. nov., Lulavia mahwii sp. nov. and Protorhoe drechseli nebuloides ssp. nov. We present differential diagnoses and images of adult moths and genitalia. Lepidoptera, Idaea, Lulavia, Protorhoe, fauna
Lulavia mahwii Khudhur & Hausmann, sp. nov. Differential diagnosis: In wing coloration and pattern no significant difference from Israeli Lulavia multipunctata (Staudinger, 1898). Male genitalia are very similar to those of L. multipunctata, but transtilla sclerites of the latter rounded towards the centre, less projecting, cornutus (bundle of microspinules) shorter: 0.3–0.4 mm. Etymology: The species is named after Mahwi who was one of the most prominent classical Kurdish poet and Sufis from Kurdistan. Mahwi was always using “Parwana – in Kurdish” meaning “Moth” as moth and flame metaphor in his poems. Farhad A. Khudhur and Axel Hausmann. 2024.

Abstract Alibertia mahechae (Gardenieae, Rubiaceae), a new tree species endemic to the forest of the Colombian Eastern Andes, is described and illustrated. The new species is distinguished by traits such as coriaceous, glabrous leaves, short stipules, pistillate flowers with 7–8-lobed corollas, and globose fruits with woody mesocarp. This new species is similar to A. occidentalis, from which it differs in the coriaceous leaf blades (vs. papyraceous in A. occidentalis), (5–)7–9 pairs of secondary veins [vs. 9–14(–16)], male flower with truncate calyx (vs. denticulate to slightly undulate), corolla tubes (15–)20–27 mm long (vs. 11–18 mm long), anthers 16–17.5 mm long (vs. 6.5–10 mm long), and female flower 7–8-merous (vs. 6-merous).

| 8:13a | [Ichthyology • 2024] Oryzias chenglongensis • A New ricefish of Genus Oryzias (Beloniformes: Adrianichthyidae) from western Taiwan
Abstract The new brackish ricefish were collected recently from western Taiwan which has been identified as the species new to science. The new species, Oryzias chenglongensis n. sp. can be well distinguished from other congeners by the following unique combination of features: (1) fin-ray counts: dorsal-fin rays 6 (6 seen in holotype); anal-fin rays 19–20 (19); pelvic-fin rays 6 (6); pectoral-fin rays 10 (10); principle caudal-fin rays i,4/5,i (i,4/5,i); (2) body compressed laterally with body depth at pelvic origin 24.0–24.3 (24.3), body depth at anal fin origin 15.5–20.4 (20.4); (3) the dorsal-fin origin inserted almost at the vertical of 14th anal-fin rays, membrane between dorsal-fin 5th and 6th rays without distinct notch in adult male; and (4) body translucent, light yellowish green or brown, scattered with minute melanophores, a narrowly dotted, longitudinal black line along the middle forward to vertical above pelvic fin; T-shape black mark of caudal fin base in male; operculum and pre-pectoral region slivery, no any silvery scales on lateral body, lip color grayish or creamy yellow and eye bluish silvery dorsally. The diagnostic characters, and comparison with related species would be also provided. Pisces, New species, fish fauna, Oryzias, fish taxonomy, brackish, conservation, Taiwan

| 2:07p | [Botany • 2024] Hieronymiella peruviana (Amaryllidaceae: Amaryllidoideae) • A New Species and A New Generic Record for the Flora of Peru
Abstract Hieronymiella peruviana (Amaryllidaceae, Amaryllidoideae, Eustephieae), a new species from the Department of Moquegua in southern Peru, is described and illustrated. This species is distinguished by having winged staminal filaments with crisscrossed sickle-shaped appendages, grows on dry slopes in semi-arid areas with pumice soils near the Huaynaputina volcano. This is the first record of Hieronymiella for the Flora of Peru. Its conservation status is assessed. Keywords: Biodiversity, conservation, Moquegua, South Peru, taxonomy  
Hieronymiella peruviana Huaylla, Slanis & Llalla sp. nov. Diagnosis. Hieronymiella peruviana is similar to H. bedelarii, differing by having weakly spatulate external tepals and flat appendages on the winged staminal filaments which take the form of crossed sickles ( vs. lanceolate external tepals and broad appendages on the winged staminal filaments which take the form of lobes with a thick edge).

| 2:16p | [Paleontology • 2024] Body Size and Evolutionary Rate Analyses reveal Complex Evolutionary History of Alvarezsauria
Abstract Some of the smallest examples of dinosaurian body size are from alvarezsaurians, an enigmatic group of maniraptoran coelurosaurians with a peculiar combination of anatomical features unique among theropods. Despite the large number of alvarezsaurian species described worldwide and the increased understanding this has provided, the body-size macroevolution of alvarezsaurians has received little attention. Here we reconstruct and analyse directional trends of alvarezsaurian body-size evolution through an integrated analysis of body mass, ontogenetic age, and morphological rate data enabled by a comprehensively revised phylogeny. Our analyses identify four periods of high morphological rate evolution (Bathonian–Callovian, Hauterivian–early Berriasian, early Cenomanian, and late Cenomanian–Turonian) that we link to the key effects of animal body-size changes for the first time, including morphological novelty, structural reduction and simplification, elevated homoplasy, and behavioral changes associated with miniaturization. In doing so, this study provides a holistic example of miniaturization in a Mesozoic vertebrate group that offers a framework for other detailed studies of animal body-size evolution, including in more disparate groups.
