| 12:02a | [Botany • 2022] Schomburgkia vandenbergiana (Orchidaceae: Laeliinae) • Description and Phylogenetic Relationships of A New, purple-flowered, Endangered Schomburgkia from north-eastern Brazil
Abstract We describe a new species of Schomburgkia, S. vandenbergiana, from north-eastern Brazil and provide a phylogenetic analysis and a summary of its conservation status. Our phylogenetic analyses indicate that S. vandenbergiana is most likely related to S. undulata and S. gloriosa. The species with dark purple flowers, S. elata, S. splendida, S. undulata and S. vandenbergiana, did not form a clade, and this trait seems to have multiple independent origins. Based on small flower size and number of keels on the disc of the lip, the new species is morphologically more similar to S. heidii, a species native to Colombia and Venezuela, but it differs in the shorter sepals and lip and erose clinandrium margin. The new species should be classified as endangered (EN) based on the IUCN criteria B1ab(i)+2ab(ii). Keywords: Monocots, Atlantic Forest flora, Epidendreae, Epidendroideae, orchid endemism, rock outcrop flora, threatened South American taxa

| 12:19a | [Botany • 2025] Passiflora quimiana (Passifloraceae) • A New Species of Passiflora Subgenus Decaloba from the Cordillera del Cóndor: Ecuador's far-flung frontier
Abstract A new species of Passiflora subgenus Decaloba, supersect. Decaloba, from the Cordillera del Cóndor in Ecuador, is described and illustrated, with its morphological similarities to other species being discussed in this paper. Passiflora quimiana exhibits the unique combination of narrow ovate to long-oval leaves and small foliaceous bracts. Morphologically it is the most similar to Passiflora quadriflora from Peru, from which it differs by the size of the floral organs, the foliaceous bracts, the structure of the corona, with the inner series slightly swollen at the apices, and the raised limen. It is currently known from a single locality only, occurring as a vine in submontane vegetation of sandstone plateaus. Keywords: condorita, Decaloba, El Quimi Biological Reserve, Granadilla, Maracuja, Passionflower
Passiflora quimiana Kuethe & H.Garzón sp. nov. Diagnosis: A species similar to Passiflora quadriflora, but differing in the larger flower (>4 cm versus <4 cm), the foliaceous bracts (opposed to setaceous), the vegetative pubescence on both stems and leaves (versus glabrous throughout), the slightly laterally compressed outer corona series (versus filiform), and the capitate structure of the inner corona (versus capillary). Etymology: The species is named after the Reserva Biológica El Quimi, one of the biological reserves within the Cordillera del Cóndor and the location of its discovery. J. R.

| 12:19a | [Botany • 2025] Typhonium cucullatum • A New Species from Sakon Nakhon Province, Northeastern Thailand [Studies on Typhonium (Araceae) of Thailand III]
Abstract Typhonium cucullatum, a new species from Sakon Nakhon Province, Northeastern Thailand, is described and illustrated. A detailed description, color plates, a discussion of similar taxa, phenology, distribution, and a conservation status assessment are provided. Keyword: Areae, Aroideae, Cretaceous sandstone, Indochina, spathe movement, Typhonium laoticum
 Typhonium cucullatum K.Z.Hein, P.Saensouk & Saensouk, sp. nov. Diagnosis: Typhonium cucullatum is unique within the genus in having a spathe limb that curves strongly forward, forming a hood-like shape at the end of pistillate anthesis and remaining intact through post-staminate anthesis despite signs of withering. In overall morphology, T. cucullatum is most similar to T. laoticum (Gagnepain, 1942), but can be readily distinguished by its spathe limb curving strongly forward (vs. the spathe limb reflexed backward in T. laoticum), a shorter staminate zone with 4–6 whorls of stamens (vs. 12–15 whorls of stamens in T. laoticum), and a stipitate appendix (vs. a sessile appendix in T. laoticum). Etymology: The specific epithet is derived from the Latin cucullatus, meaning ‘hooded’, referring to the spathe limb becoming forwardly curved and hood-like.

| 3:43p | [Botany • 2025] Boswellia oropedionis (Burseraceae) • A New frankincense tree Species from Socotra, and notes on B. ameero and B. bullata
Abstract
The new species Boswellia oropedionis Thulin and M.H.Weber is described, illustrated by photographs and mapped. This tree is only known from a small population growing on level limestone on the Qatariyah plateau in southern Socotra and is the twelfth endemic species of Boswellia from the Socotra archipelago. It differs from B. dioscoridis Thulin by having 7–9-foliolate leaves with pubescent nerves on the upper side, and by having larger flowers and fruits. Boswellia ameero Balf.f. is shown to have broadly winged pyrenes, an unusual feature in the genus and unique among the species on Socotra. Two new localities are reported for B. bullata Thulin, which is shown to have mostly narrowly winged pyrenes. Keywords: endemic species, taxonomy, Yemen
Boswellia oropedionis Thulin and M.H.Weber sp. nov. A species differing from Boswellia dioscoridis Thulin by having 7–9-foliolate leaves pubescent with crisped hairs along the nerves above (versus leaves mostly 11–17-foliolate and entirely glabrous above), petals 7.0 × 3.5 mm (versus 5.0 × 2.5–3.0 mm), stamens with filaments 3 mm (versus 1.5–2.0 mm) long and anthers 2.8 mm (versus 1.2–1.8 mm) long, disk 5.5 mm (versus 3.0–3.5 mm) in diameter, fruits 12–15 × 10–12 mm (versus 7–12 × 4–9 mm) and pyrenes 8.0–10.0 × 4.5–5.5 mm (versus 5.5–7.5 × 2.0–4.0 mm). Etymology: The epithet ‘oropedionis' (from Greek for ‘of the plateau') refers to the habitat of the species. Mats Thulin, Michael H. Weber and Sami Ali Mohammed Mubarak. 2025.

| 3:51p | [Herpetology • 2025] Guibemantis sioka • A New Species of mantellid frog of the Genus Guibemantis (Anura: Mantellidae) from south-eastern Madagascar
Abstract We describe a new species of arboreal mantellid frog of the genus Guibemantis (classified in the subgenus Guibemantis) from Madagascar. The new species, Guibemantis sioka sp. nov., is morphologically similar to G. depressiceps but differs by a high uncorrected genetic distance greater than 6% in the mitochondrial 16S rRNA gene from all other related species, and by a conspicuous dark-light marbling of the flanks, relatively large hands, and the structure of its advertisement calls from its closest relatives. Single individuals of the new species have been found at each of three high-elevation sites (1210–1650 m a.s.l.) in the Southern Central East and South East of Madagascar (Ranomafana National Park, Ivohiboro Reserve, and Andohahela National Park). If this apparent rarity was confirmed by future studies, it would stand in stark contrast to other Guibemantis which are often observed in large breeding aggregations.

| 4:22p | [Ichthyology • 2025] Bagarius protos & B. dolichonema • A Taxonomic Review of Bagarius Catfish (Siluriformes: Sisoridae) in the Salween and Irrawaddy Rivers, with Descriptions of Two New Species from China and Myanmar
Abstract The genus Bagarius is a group of large, benthic, predatory catfishes found in South and Southeast Asia. Two new species of Bagarius, B. protos Zeng & Chen, sp. nov., and B. dolichonema Zeng & Chen, sp. nov., are described from the Salween River Basin, Yunnan Province, China, and Irrawaddy River Basin, Myanmar, respectively. Bagarius protos and B. dolichonema both differ from B. vegrandis and B. suchus in their large size and the adipose-fin origin being nearly vertical to the anal-fin origin. Bagarius protos most closely resembles B. lica and B. rutilus in overall morphology but can be distinguished from B. lica by the absence of the brow ridge formed by the lateral margin of the frontal and from B. rutilus by the dark yellow (instead of orange) coloration of the fins in life. It further differs from two other congeners in its short filamentous extensions of the pectoral-fin spine. Bagarius dolichonema is morphologically and genetically most similar to B. bagarius; it can be distinguished from B. bagarius by strong dorsal spines slightly flattened immediately anterior to the adipose fin, distally slender neural spines of the 4th–6th vertebrae, and shorter filamentous extensions of the pectoral-fin spine. This new species further differs from three other congeners by its longer filamentous extensions of the pectoral-fin spine and weak notches in the anterodorsal margin of the first dorsal pterygiophores. Molecular phylogeny based on the cytochrome c oxidase subunit I (COI) gene also confirms the validity of these two new species. The estimated K2P genetic distances between B. protos and congenerics range from 8.0% to 12.6%, and between B. dolichonema and congenerics range from 5.7% to 12.1%. Key Words: Cryptic species, phylogeny, Southeast Asia, taxonomy
Bagarius protos Zeng & Chen, sp. nov. Diagnosis. Bagarius protos can be distinguished from congeners by having the following combination of characteristics: eye small (5–8% HL), lateral margin of frontal straight, not forming brow ridge, strongly notched in antero-dorsal margin of the first dorsal-fin pterygiophore, dorsal spine strong (width 10.6–14.4 times its length), filamentous extensions of pectoral-fin spine reaching posterior of anal-fin base, neural spines of 4th–6th vertebrae immediately anterior to adipose fin distally slender, adipose-fin origin at vertical through or very slightly posterior to anal-fin origin, caudal peduncle deep (4.2–5.1% SL). Etymology. The epithet name “protos” consists of the Greek “protos,” meaning original (at first), referring to the species being in the most primitive position in the phylogenetic tree of genus Bagarius. The suggested common name in Chinese is 原魾 (Pinyin: yuan pi).
Diagnosis. Bagarius dolichonema can be distinguished from congeners by the following combination of characteristics: lateral margin of frontal straight, not forming brow ridge, dorsal spine strong (width 9.9–14.1 times its length), weakly notched antero-dorsal margin on pterygiophore of first dorsal-fin, filamentous extensions of pectoral-fin spine beyond posterior of pelvic-fin base and some reaching anus, neural spines of 4th–6th vertebrae immediately anterior to adipose fin distally slightly flattened, adipose-fin origin at vertical through or very slightly posterior to anal-fin origin, caudal peduncle slender (3.8–4.6% SL). Etymology. The epithet name “dolichonema” comes from the Greek adjective “dolikhos,” meaning long, and the noun “nēma,” meaning thread or yarn, which refers to the length of filamentous extensions with pectoral-fin spines and caudal fins that are the longest in congeners except for B. bagarius. The suggested common name in Chinese is 长丝魾 (Pinyin: chang si pi). Yu-Yang Zeng, Xin-Rui Pu, Hao-Tian Lei, Thaung Naing Oo and Xiao-Yong Chen. 2025.
