| 2:50a | [Botany • 2019] Clinanthus inflatus & Ismene parviflora • Taxonomic Novelties in Amaryllidaceae from the Department of Ancash, Peru, and A New Combination in Clinanthus
Abstract Clinanthus inflatus and Ismene parviflora (Amaryllidaceae) are described from Ancash Department in Peru. The flower of C. inflatus is urceolate, and resembles that of Urceolina (Amaryllidaceae tr. Eucharideae), a unique morphology for the genus. Ismene parviflora, with its small, loosely formed, narrowly funnelform-tubular perigone with a ventricose limb, appears to have some affinity to subgen. Pseudostenomesson and may represent an intermediate form between the former and species of subgen. Ismene. Stenomesson rubrum is transferred to Clinanthus as C. ruber on the basis of its narrowly lorate leaf morphology. Keywords: Amaryllidaceae, Andean biodiversity, Clinantheae, Hymenocallideae, Ismene, monocots, Neotropical flora, taxonomy
Clinanthus inflatus Meerow & A.Cano, sp. nov. Diagnosis: This species differs from all known species of Clinanthus by the uniquely inflated perigone, the shape and coloration of which is reminiscent of the genus Urceolina Rchb. (Eucharideae) or superficially certain species of Andean vaccinioid Ericaceae. Etymology: The specific epithet is from Latin and refers to the abruptly inflated perigone.
  Ismene parviflora Meerow & A.Cano, sp. nov. Diagnosis: Ismene parviflora differs from all other species of the genus by the small flowers (< 4 cm long), that are loosely funnelform, terminating with a ventricose limb, but not infundibular to the degree of I. vargasii and I. morrisonii (subgen. Pseudostenomesson Meerow), the latter species to which it approaches in size. All other species of Ismene have large, crateriform flowers (subgen. Ismene) or large, zygomorphic flowers (subgen. Elisena). Distribution and ecology: Ismene parviflora is known only from the type locality (Fig. 3), in seasonally dry vegetation. Etymology: The specific epithet is from Latin and refers to the small size of the flowers. Alan W. Meerow and Asunción Cano. 2019.

Ismene parviflora, con su forma suelta, perigonio angostamente funeliforme-tubular con una limbo ventricoso, parece tener alguna afinidad al subgen. Pseudostenomesson y puede representar una forma intermedia entre el primero y las especie de subgen. Ismene. Stenomesson rubrum se transfiere a Clinanthus como C. ruber, sobre la base de su morfología de hoja acintada estrecha. | ||||||
| 3:01a | [Botany • 2024] Tricyrtis lingyunyanensis (Liliaceae) • Taxonomic Revision of Tricyrtis in Taiwan and A New Species
Abstract We examined morphological characteristics, elevation, and phenology to revise Tricyrtis in Taiwan. As a result, we confirmed five species and one variety. Tricyrtis lingyunyanensis is a new species found only in the north on Wunfong Mountain, Chiayi Country, Taiwan, at an elevation of approximately 1100 m. This study provides a detailed assessment of the morphology of each species by offering descriptions and comparative photographs. morphology, new taxon, Sect.

| 4:01a | [Botany • 2025] Hoya biruensis (Apocynaceae: Asclepiadoideae) • A New night-blooming Species of Hoya from Borneo
Abstract In the present paper, we describe Hoya biruensis, a new species from Borneo, Indonesia, West Kalimantan. It is characterised by a shrubby epiphytic pendulous habit, linear leaves, exceptionally long green peduncles produced at almost every node, and single, night-blooming flowers. We compare it to two morphologically similar species, H. spartioides and H. retrorsa, which are also endemic to Borneo. Keywords: epiphyte, Hoya retrorsa, Hoya spartioides Indonesia, West Kalimantan

| 2:56p | [Ichthyology • 2025] Tariqilabeo iranicus • A New Species of labeonine fish (Cypriniformes: Cyprinidae) from the Makran Basin in Iran
Abstract A new species of labeonine fish, Tariqilabeo iranicus sp. nov. is described from the Makran drainage basin of Iran. It is distinguished from its closest congener, Tariqilabeo diplochilus, by having a silvery spot on the operculum, and a snout shorter than the postorbital length. It is further distinguished from its congeners by a combination of characters: 34–36 lateral-line scales, 11–14 predorsal scales, 22–24 total gill rakers on the first branchial arch, 3+8 ½ dorsal-fin rays, 14–16 pectoral-fin rays, 9 pelvic-fin rays, 3+5½ anal-fin rays, 2–3 scales between anal-fin origin and anus, 7–8 scales between posteriormost pelvic-fin base and anus, 2 pairs of small barbels, presence of fringes on the rostral fold, and absence of horny tubercles on snout and cheek in males. Tariqilabeo iranicus sp. nov. is further distinguished from T. diplochilus by a K2P nearest-neighbor distance of 4% in the COI barcode region. A key to the species of Tariqilabeo is also presented.

| 4:39p | [Herpetology • 2025] Homonota chelemini • A New Gecko (Phyllodactylidae: Homonota whitii group) from the Diaguita highlands, Argentina, with an updated phylogeny for the genus
Abstract The South American Transition Zone (SATZ) connects the Neotropical and Andean regions, stretching from western Venezuela to northern Chile and central-western Argentina. In Argentina, the northwestern Altoandina Cuyana province includes arid and semi-arid ecosystems, particularly the Diaguita District, spanning Catamarca, La Rioja and northern San Juan. This mountainous region, including the Sierra de Famatina and Cordillera Frontal de los Andes, hosts species adapted to extreme conditions. Despite its biodiversity, the region's endemicity and phylogenetic uniqueness remain poorly understood, especially as these ecosystems face growing climate threats, such as heatwaves. Geckos (Order Gekkota) are one of the oldest lizard clades, with divergences over 150 million years ago. Particularly, the genus Homonota (Phyllodactylidae) is endemic to the southern cone of South America, primarily in Argentina, with species also found in Brazil, Paraguay, Bolivia and Uruguay. As part of a broader investigation on geckos of this genus and to advance their systematic study, we generated data from two mitochondrial and 12 autosomal loci across 14 species, along with a comprehensive morphological dataset of meristic measurements and scale counts. Detailed analyses were conducted within an integrative species assessment framework. Consequently, we describe a new species of Homonota from the Diaguita biogeographic district in northwestern Argentina, representing the northernmost member of the H. whitii group. The species inhabits a mountainous region known for its micro-endemism, further highlighting the area as an important biodiversity hotspot for dryland ecosystems. Additionally, we provide an updated molecular phylogenetic hypothesis for the genus, offering new insights into the evolutionary history within Homonota and the broader biodiversity of the SATZ.
