| 1:58a | [Entomology • 2024] Cyphonia dayuma & C. kellyswingi • New Species and Records of the Treehopper Genus Cyphonia (Hemiptera: Membracidae) from the northern Amazonia lowlands of Ecuador
Abstract Summary. We describe two new species of Cyphonia Laporte, 1832 from the Amazonia lowlands of Ecuador: Cyphonia dayuma Montalvo-Salazar & Karbaum n. sp. (♀) and C. kellyswingi Montalvo-Salazar & Torres n. sp. (♀). We also add two new records for Ecuador from an urban forest remnant in the Amazonia: Cyphonia clavigera (Fabricius, 1803) and C. longistyla Sakakibara, 1972. With this contribution, the number of known species of Cyphonia inhabiting Ecuador is elevated to seven. We lastly provide a key to the known Cyphonia species of Ecuador.

| 5:42a | [Botany • 2024] Petalidium namibense (Acanthaceae: Ruellieae) • A New Species from Namibia
Abstract Petalidium namibense, hitherto confused with P. englerianum, P. rossmannianum, and the widespread P. variabile, is here described as a new species. It is a range-restricted species, only known from the area to the southwest, west and northwest of Puros in the Kaokoveld Centre of Endemism, northwestern Namibia, where it grows at the base of rocky outcrops, on arid hillsides, and along ephemeral riverbeds and drainage lines. Diagnostic characters for P. namibense include the pale grey appearance of the plants, corky bark on older stems, vegetative parts with a dense white indumentum of relative long dendritic trichomes appearing lanate, flowers borne in short few-flowered dichasia, and bracteoles narrowly ovate. The flowers of P. namibense are distinctive in having the two upper corolla lobes discolorous, abaxially light brown, adaxially vermillion, without nectar guides, and connate towards the base for 25–40% of their length. The anterior lobe is adaxially magenta with two relative long, narrowly triangular yellow nectar guides. The two lateral lobes are adaxially vermillion, or distally magenta, grading to vermillion towards the throat, and lack conspicuous nectar guides. A comparison of key morphological features distinguishing P. namibense from P. sesfonteinense, its closest relative in appearance, as well as from P. englerianum, P. rossmannianum, and P. variabile, is provided. Based on IUCN Red List criteria, a provisional conservation assessment of Vulnerable (VU) is recommended for the new species. endemism, flora, Kaokoveld Centre of Endemism, Kunene Region, Namib Desert, Ruellieae, Puros, taxonomy, Eudicots
Petalidium namibense Swanepoel & A.E.van Wyk, sp. nov. Diagnosis:—A woody dwarf shrub up to 1 m tall, morphologically most similar to Petalidium sesfonteinense, differing by having the leaf lamina ovate, elliptic, suborbicular or orbicular (vs. ovate, elliptic or oblanceolate); bracteoles with trichomes dendritic, interspersed with glandular ones (vs. trichomes glandular with in addition appressed simple ones towards base); corolla shorter, 15.0–17.5 mm (vs. 20–24 mm long), upper lobes rectangular, smaller, 4.9–5.2 × 2.9–3.2 mm (vs. obovate, 5.8–8.2 × 3.5–4.3 mm), upper and lateral lobes differently coloured than anterior lobe with nectar guides absent or inconspicuous (vs. all lobes similarly coloured, nectar guides on upper and lateral lobes conspicuous). Etymology:—The specific epithet refers to the Namib Desert to which Petalidium namibense is endemic. The Namib Desert in its broadest definition, stretches along the Atlantic Ocean from Saõ Nicolau (Bentiaba) in Angola through Namibia to the Olifants River in South Africa (Seely 2004, Goudie & Viles 2015).

| 8:35a | [Entomology • 2023] Proaegeria murzini • On the Systematic Position of the Genus Proaegeria Le Cerf 1916 (Lepidoptera: Sesiidae) with Description of A New Species
Abstract A new species, Proaegeria murzini sp. n., is described and illustrated from a series of males and a female collected in the vicinities of Kindia, Guinea. The new species is well distinguished from the closest relative, Proaegeria vouauxi Le Cerf, 1916, by the colouration of the abdomen and the details of the structure of the hindwing. The study of the genital structures of both the male and the female of the new species unequivocally determines the systematic position of this genus in the tribe Sesiini.

| 2:54p | [Botany • 2024] Zingiber zulkifliana (Zingiberaceae) • A New Species from Taman Negeri Rompin, Pahang, Malaysia
Silver-leaved Zingiber group (Zingiberaceae) previously known only from Borneo was now appended with a new species from Taman Negeri Rompin, Pahang, Peninsular Malaysia — marking the first record of this group outside the Borneo island. The new species, Zingiber zulkifliana Tan, Besi & Go was described, illustrated, and compared to its closest relatives in this study. An artificial key to differentiate the species of the silver-leaved Zingiber was also provided.  Zingiber zulkifliana Tan, Besi & Go sp. nov.

| 3:22p | [Paleontology • 2024] Nipponopterus mifunensis • Reassessment of an azhdarchid Pterosaur specimen from the Mifune Group, Upper Cretaceous of Japan
Abstract The Japanese pterosaur record is relatively scarce and represented by a limited number of fragmentary specimens from Cretaceous deposits, including a partial cervical vertebra of an azhdarchid from the “Upper Formation” (Turonian-Coniacian) of the Mifune Group in Kumamoto Prefecture, on the island of Kyushu, Japan. Here, we redescribe this notable Japanese pterosaur specimen and test its phylogenetic position. We interpret it as a sixth cervical vertebra and identify diagnostic features that enable its recognition as a new taxon, Nipponopterus mifunensis gen. et sp. nov. It is noteworthy that this represents the first nominal species of pterosaur from Japan and that this new taxon shows numerous quetzalcoatline features, being strikingly similar to the unnamed Burkhant azhdarchid from the Turonian–Coniacian of Mongolia. Our phylogenetic analysis places Nipponopterus as a sister taxon to the Burkhant azhdarchid and nested within the clade of Quetzalcoatlinae.  Nipponopterus mifunensis gen. et sp. nov.

| 9:57p | [Ichthyology • 2024] Schizodon unimaculatus • A New Species from the lower Rio São Francisco with a reappraisal of the Schizodon species presenting a caudal-peduncle blotch (Characiformes: Anostomidae)
Abstract Schizodon unimaculatus new species, is described from the lower sections of the Rio São Francisco in northeastern Brazil. The new species differs from all known Schizodon species by the combination of presenting a subinferior mouth, a prominent dark brown blotch on the caudal peduncle, a dark brown longitudinal stripe along the lateral line, and three series of small dark dots horizontally aligned forming interrupted lines on the dorsal and middle regions of the trunk. It differs from congeners with a horizontal stripe and a dark blotch on the caudal peduncle, viz., S. knerii, S. rostratus, S. jacuiensis, S. nasutus, S. isognathus, S. altoparanae, S. vittatus, and S. trivittatus, by the combination of scale counts in lateral line and around caudal peduncle, color pattern, mouth position, and body proportions. The subinferior mouth additionally distinguishes the new species from S. knerii, S. jacuiensis, S. nasutus, S. altoparanae, S. platae, S. isognathus, and S. rostratus. Principal component and canonical variation analyses additionally distinguish the new species from S. knerii, S. altoparanae, and S. nasutus. We discuss the taxonomic history, relationships, and significance of mouth morphology, coloration, and meristic characters in taxonomic studies of Schizodon.
