| 2:02a | [Botany • 2025] Fritillaria behcetiana (Liliaceae) • A New Species from eastern Anatolia (Türkiye)
Abstract Fritillaria behcetiana sp. nov. is described as a new species from Bingöl Province in eastern Anatolia, Türkiye. It is closely related to F. shehbazii, F. chlororhabdota and F. pinardii, but differs from them in several morphological features, including leaf lenght and colour, perianth segment size and colour, anther colour and length, filament length, style lenght and branching. The new species is described in detail, including distribution, ecology, conservation status and photographs with comparisons to F. shehbazii, F. chlororhabdota and F. pinardii.

| 2:17a | [Crustacea • 2025] Megapleonum ferrumequinum, M. wangjiani, ... • Four New Freshwater Crab Species of the Genus Megapleonum (Decapoda: Potamidae) from Guangdong, China
Abstract Four new species of the poorly known genus Megapleonum Huang, Shih & Ahyong, 2018, are described from Guangdong Province, China: Megapleonum falx sp. nov. from Huizhou City, M. yangdongense sp. nov. from Yangjiang City, and both M. ferrumequinum sp. nov. and M. wangjiani sp. nov. from Maoming City. These four new species are all morphologically and genetically distinct from each other and the two known congeners Megapleonum ehuangzhang Huang, Shih & Ahyong, 2018 and Megapleonum shenzhen Huang & Mao, 2021. The extremely divergent morphology of the gonopod 1 of these species alone immediately sets them apart, but there are also distinct differences in other characters, including the carapace, ambulatory leg, and maxilliped 3 exopod flagellum. A phylogeny constructed using the mitochondrial 16S rDNA reveals that all species of Megapleonum form a deep-rooted monophyletic group with significant interspecific genetic distances, supporting the generic placement and specific treatments of these new taxa. A key to the species of Megapleonum is also provided. Key words: 16S rDNA, aquatic species, China, new taxa, systematics

| 6:47a | [Botany • 2025] Garcinia isthmensis (Clusiaceae) • A New tree Species for Central America
Abstract We present a new species, Garcinia isthmensis Mouzinho, sp. nov. ined., known to occur in Costa Rica and Panama. Garcinia isthmensis is described and distribution data, photographs and preliminary conservation status are provided, as well as its diagnostic characteristics and morphological affinities. Guttiferae, jorco, Mesoamerica, Neotropics, satra, Eudicots
Garcinia isthmensis Mouzinho, sp. nov. Diagnosis:—Garcinia isthmensis is vegetatively similar to G. magnifolia due to its elliptical to elliptic-oblong shape
and size of the leaf blades (≥ 19 cm long), but differs from it due to its slightly verrucose branches (vs. smooth in G.
magnifolia), conspicuous exudate canals (vs. inconspicuous in G. magnifolia), staminate flowers with 40–55 stamens
per flower (vs. ca. 30 stamens in G. magnifolia), non-rostrate fruits (vs. rostrate in G. magnifolia) and fruit pedicels of
33.5–44 mm long (vs. 7–10 mm long in G. magnifolia). Etymology:—The epithet refers to the Panama isthmus, that connects Meso- and South American regions. Thiago MOUZINHO, Juan F.

| 8:45a | [Ichthyology • 2025] Barbatula fluvicola & B. ommata • Two New Species of Stone Loaches of the Genus Barbatula (Cypriniformes: Nemacheilidae) from Europe with a neotype designation of B. barbatula
Abstract Ten species of Barbatula are recognised in Europe, west of the Urals: B. barbatula, B. caucasica, B. hispanica, B. leoparda, B. pironae, B. quignardi, B. sturanyi, B. taurica, B. vardarensis and B. zetensis, with B. caucasica and B. taurica formerly considered subspecies of B. barbatula. A comprehensive dataset of the DNA barcoding gene coI recovered four major clades within Europe: three in Eastern Europe including B. caucasica, B. pironae, B. sturanyi, B. taurica, B. vardarensis and B. zetensis, and one in Western Europe including B. barbatula, B. hispanica and B. leoparda. The results further indicated several genetic lineages, representing potentially new species. Recent surveys in Switzerland revealed two new species of Barbatula, within the Western clade, which are herein described. Barbatula fluvicola, a new species, inhabits streams and rivers in the upper and middle Rhine drainage in Switzerland and Germany, as well as the upper Danube drainage in Germany and Austria. Barbatula ommata, a new species, is mostly confined to lakes of the Aare-Rhine system. The two new species overlap geographically in Switzerland, where they occupy different habitats. Morphological differences, species delimitation analyses, phylogenetic reconstruction and genetic distances based on the coI gene corroborates the recognition of the two new species. To stabilise the nomenclatural status and the consequent use of the nomen B. barbatula, we are herein designating an unambiguously identifiable neotype from the Lez River population, previously recognised as B. quignardi, to clarify the identity of the nominal species Cobitis barbatula Linnaeus, 1758. Keywords: biodiversity, Danube River, European fishes, freshwater lakes, Rhine River, systematics
Barbatula fluvicola, new species Etymology. The name fluvicola is from Latin meaning inhabitant of rivers, alluding to the stream preference habitats where this species has been collected. A noun in apposition. Vernacular name. North-Prealpine Stone Loach (English), Nord-Voralpine Bartgrundel (German), Loche Préalpes du Nord (French). Barbatula ommata, new species Etymology. Barbatula ommata from the Greek ómmata (ὄμματα) for eyes, and is given in reference to the species diagnostic great diameter of its eyes. A noun in apposition. Vernacular name. Lake Stone Loach (English), Seebartgrundel (German), Loche du Lac (French). Bárbara B. Calegari, Jörg Freyhof, Conor Waldock, Bernhard Wegscheider, Dario Josi, Lukas Rüber, Ole Seehausen. 2025.

| 11:25a | [Botany • 2025] Garcinia kusumae (Clusiaceae) • A New Species From Assam, India
ABSTRACT A new species, Garcinia kusumae (Clusiaceae), is described and illustrated from Assam, India. Detailed comparisons with morphologically similar species are provided to support its novelty. This discovery contributes to the underexplored diversity of Garcinia in Northeast India and highlights the importance of continued botanical exploration in the region. Keywords: Clusiaceae, Garcinia section Brindonia, new species, Northeast India
Garcinia kusumae J. Sarma & Barbhuiya sp. nov. Diagnosis: The newly described species shows superficial similarity to Garcinia assamica J. Sarma, P.S. Shameer & N.N. Mohanan, G. cowa Roxb. var. cowa and var. kydia (Roxb.) Shameer & N. Mohanan, G. indica (Thouars) Choisy, and G. succifolia Kurz in having fasciculate axillary and terminal inflorescences, tetragonous flowers with creamy to yellow petals, and stamens united into a single central bundle. However, it differs from all the aforementioned taxa in possessing up to 15 staminate flowers per fascicle, fewer stamens (≤ 30) per flower (except G. assamica), and berries bearing blackish resinous exudations on the surface. ...  Etymology: The specific epithet kusumae is named in honor of the late Kusum Devi, mother of the first author, in recognition of her enduring support and sacrifices for his education at Sainik School, Goalpara, Assam, and his further studies, as well as for inspiring him to work hard from his early childhood. Ethnobotanical Uses: The plant is locally known as Thoikora in Assamese. The sun-dried pulp is preserved and used to make a sherbet (soft drink) with salt and sugar to taste, serving as a remedy for heat stroke during hot summer days and for relief from thirst. It is also used as a curry ingredient with fish, as an antidiabetic remedy, and to control dysentery. The seed aril, which is slightly sour and sweet, is eaten raw—often mixed with a little salt, chillies, and a pinch of mustard oil. Jatindra Sarma and Hussain A. Barbhuiya. 2025.

| 11:59p | [Botany • 2025] Sonerila gigantea (Melastomataceae: Sonerileae) • A New Species from the Western Ghats of India
Abstract The Sonerila gigantea is a new acaulescent species found in Mallalli Falls, Kodagu District, Karnataka, India, part of the Western Ghats. This species has distinguishable characteristics like habit from the genus Sonerila worldwide. S. gigantea is compared with Sonerila wallichii Benn. & Sonerila grandis Ridl. The species shown differ in several characteristics like habit, leaf and inflorescence, described in a table form with taxonomic keys and even explained micro morphology characters like pollen and seed. This report deliberates on the new species Sonerila gigantea from the Western Ghats, India. Keywords: Acaulescent, giant habit, Kodagu, stemless sonerila, white patches
Sonerila gigantea Karadakatti & Kakkalameli sp nov. The Sonerila gigantea can be easily distinguished by its size of the habit. Leaf size varies from 15 –30 cm, and the texture of the lamina shows white patches, 20 –40 flowers in each inflorescence, fruit glabrous, variations of pollen shape and size, and even seed texture. S. gigantea resembles the mentioned key characteristics of S. grandis Ridl. from Indonesia and S. wallichii Benn. from Karnataka, India described. Etymology: The specific epithet refers to the plant being a giant or large individual (gigantic/gigantea) compared to the existing Sonerila species in the world, except the species reported from the Indonesia Sonerila grandis Ridl., hitherto the plant described with the word using the largest habit. However, it shows a lot of variation in morphology, with the present report on Sonerila gigantea. The plant is located on Mallalli Falls Road, Coorg District, Karnataka, India.
