| 2:34a | [Botany • 2024] Heliconia longipedunculata (Heliconiaceae) • A New Species of Heliconia from Colombia: A Proposal Based on Different Characters
Abstract Heliconia (Heliconiaceae) is a genus of giant rhizomatous herbs that have bright and striking bract inflorescences. The family consists of one genus and about 194 species that occur naturally in the tropical regions of the world, concentrating their greatest diversity and endemism in the Andean foothills and the Pacific region of Colombia, with approximately 120 species of the total registered for the world. Within the species of this genus there is high morphological variation, which sometimes makes clear identification of Heliconia specimens difficult. So is the case of Heliconia platystachys Baker, which contains two morphologically distinct groups of plants distinguished by the size and color of the bracts, the floral bracts, the mucilage that covers the flowers, and the shape of the staminodium. These structures of floral biology such as staminodium are of great taxonomic value in the study of the species within the genus Heliconia. The main goal of this work was to study Heliconia populations, which are found on the western slope of the Central Cordillera of Colombia at elevations between 970 and 1200 m, for which the morphoanatomical and palynological attributes were analyzed. We want to explore in this work whether the variation exhibited by these populations and their distribution allows us to postulate the occurrence of a new species with sufficient evidence for its separation.

| 3:22a | [Botany • 2022] Myriophyllum rubricaule (Haloragaceae) • a M. aquaticum look-alike only known in cultivation
Abstract A confusingly labeled water-milfoil of obscure status, known only in cultivation, is here formally described as a new species, Myriophyllum rubricaule Valk. & Duist. sp. nov. This species has fully replaced M. aquaticum in the horticultural trade in Europe since the addition of M. aquaticum to the list of invasive alien species of Union concern (EU regulation no. 1143/2014) in 2016. This manuscript provides a morphological description of M. rubricaule sp. nov., and its distinction from M. aquaticum is further supported by molecular data (chloroplast and nuclear loci). Keywords: Myriophyllum, water-milfoil, EU regulation no. 1143/2014, invasive plant, horticulture  Myriophyllum rubricaule Valk. & Duist. sp. nov. Diagnosis: Herba perennis aquatica vel paludigena. Folia omnia verticillata pectinata. Flores unisexuales, solae plantae femininae culturaeque cognitus. Flores intra axillas foliorum solitarii. Planta valde similaris Myriophyllo aquatico, sed caules foliaque modice, caules purpurei et folia emergentia virida.

| 3:37a | [Botany • 2020] Paepalanthus fabianeae (Eriocaulaceae) • A New Microendemic Species from a Morphologically Coherent Clade
Abstract We describe and illustrate Paepalanthus fabianeae , a new species of Eriocaulaceae from the central portion of the Espinhaço Range in Minas Gerais, Brazil. Previous phylogenetic evidence based on analyses of nuclear (ITS and ETS) and plastid (trnL-trnF and psba-trnH) sequences revealed P. fabianeae as belonging to a strongly supported and morphologically coherent clade containing five other species, all of them microendemic, restricted to the Espinhaço range. Due to the infrageneric classification of Paepalanthus being highly artificial, we preferred not assigning P. fabianeae to any infrageneric group. Paepalanthus fabianeae is known from two populations growing in campos rupestres (highland rocky fields) in the meridional Espinhaço Range. The species is characterized by pseudodichotomously branched stems, small, linear, recurved, and reflexed leaves, urceolate capitula, and bifid stigmas. Illustrations, photos, the phylogenetic position, and a detailed description, as well as comments on habitat, morphology, and affinities with similar species are provided. The restricted area of occurrence allied with threats to the quality of the habitat, mainly due to quartzite mining, justifies the preliminary classification of the new species in the Critically Endangered (CR) category using the guidelines and criteria of the IUCN Red List. Keywords: Campos rupestres; Poales; taxonomy

| 9:02a | [Entomology • 2022] Pseudohampsonella medogensis • A New Species of the Genus Pseudohampsonella Solovyev & Saldaitis (Lepidoptera: Limacodidae) from Xizang Autonomous Region, China
Abstract The sixth species of the genus Pseudohampsonella Solovyev & Saldaitis, 2014, P. medogensis sp. nov., is described from Xizang Autonomous Region, China. The new species is morphologically similar to the congeners P. bayizhena Wu & Pan, 2015 and P. hoenei Solovyev & Saldaitis, 2014, but differs from them by the uncus slightly waved with a blunt apex and the phallus distinctly curved mesally. Images of adults and genitalia are presented. The circumscription of the new species is supported molecularly by the analysis of the pairwise genetic distances using mitochondrial cytochrome c oxidase subunit I (COI) gene. The minimum interspecific distance value between the new species and its sister species, P. lii Wang & Li, 2017, is 7.7%.

| 9:17a | [Herpetology • 2024] Dibamus elephantinus • A New Species of Blind Skink of the Genus Dibamus Duméril et Bibron, 1839 (Squamata: Dibamidae) from Cambodia
Abstract We describe a new species of blind skink of the genus Dibamus Duméril et Bibron, 1839 based on five specimens collected from Bokor National Park, Kampot Province, southern Cambodia. Dibamus elephantinus sp. n. can be distinguished from its congeners by the following combination of morphological characters: snout-vent length (SVL) up to 129.3 mm; tail length comprises 17–22% of SVL; rostral suture incomplete; nasal and labial sutures complete; single postocular; three scales at the posteromedial edge of first infralabial; two scales at the posterior edge of second infralabial; the medial sublabial scale enlarged; 19 midbody scale rows; 22 transverse scale rows just posterior to head; 17–19 transverse scale rows just anterior to vent; 178–202 ventral scales; 46–52 subcaudal scales; relative size of frontal to frontonasal (FSW/FNSW) 127–136%; relative size of interparietal to surrounding scales (IPW/NSW) 111–140%; in males hindlimbs longer than head length (HLL/HL 74–78%); the light colored band on the body may be present or absent. We provide an osteological description of the new species based on micro-CT data. Genetically and morphologically Dibamus elephantinus sp. n. is most closely related to D. dalaiensis inhabiting the western part of the Cardamom Mountains in Cambodia. The new species inhabits montane evergreen forests of Damrei Range (also known as Elephant Mountains) at elevations of ca. 1000 m a. s. l. Our study brings the number of species in the genus Dibamus to 27; Dibamus elephantinus sp. n. is the second species of Dibamus to be recorded from Cambodia.  Dibamus elephantinus sp. n.

| 4:18p | [Entomology • 2022] Metanarsia moroccana • A New Species of Metanarsia Staudinger, 1871 (Lepidoptera: Gelechiidae) from Morocco
Abstract Metanarsia moroccana sp. nov. is described from Eastern Morocco. The species is remarkable in having an unmodified recurved labial palpus and the adults active in October. Adults and male genitalia of the new species are illustrated, and the adults compared with the most superficially similar Metanarsia dahurica Bidzilya, 2005. An annotated list of the species of Metanarsia is provided.
Metanarsia moroccana sp. nov. Diagnosis: The new species is recognizable externally by its reddish brown forewing with diffuse reddish pink transverse fasciae (Figs 1–3) and recurved labial palps with an unmodified segment 2 and short segment 3 (Figs 7, 8). Metanarsia kosakewitshi Piskunov, 1990 and Metanarsia guberlica Nupponen, 2010 have somewhat similar reddish-brown forewings but differ in the absence of fasciae. Additionally, M. kosakewitshi is lighter, uniformly reddish brown and straight labial palps Oleksiy V. Bidzilya. 2022.
