| 7:43a | [Botany • 2022] Pleroma barbellatum (Melastomataceae: Melastomateae) • A New Species from the Southern Espinhaço, Minas Gerais, Brazil
Abstract Pleroma barbellatum P.J.F.Guim., D.Nunes & I.M.Araújo a new species of Melastomataceae (Melastomateae) from the Espinhaço Range of Minas Gerais State, Brazil, is described and illustrated, and their affinities and diagnostic characters are here discussed. Pleroma barbellatum is closely related to P. formosum, P. martiale, and P. riedelianum. They share a similar habit and leaves that are alike in size and shape. However, they can be distinguished by differences in the trichomes of the branches, leaves and inflorescences, in addition to other characters related to the type of inflorescence and size of the bracteoles. We recommend a conservation status of Endangered for P. barbellatum. Keywords: Campos Rupestres, Diamantina Plateau, Espinhaço Meridional, Grão-Mogol, Melastomateae
Pleroma barbellatum P.J.F.Guim., D.Nunes & I.M.Araújo sp. nov. Diagnosis: A shrub or tree 1–2 m or 2–3 m tall, is readily recognized by its barbellate and eglandular trichomes (on the branches, petioles, leaf blade surfaces, pedicels, bracts and bracteoles, hypanthia, outer surface and margins of sepals, and base of style), oblong, elliptic or lanceolate leaf blades 15–44 × 6.5–13.5 mm, with strigose indumentum on the adaxial surface, and obtuse, rounded or cuneate base, terminal cyme inflorescences 3–5 cm long with up to 5 flowers or flowers solitary and terminal, campanulate hypanthia covered by a strigose bristly indumentum, and ensiform sepals 4–6 × 1.5–2.5 mm. Pleroma barbellatum is similar to Pleroma formosum (Cogn.) P.J.F.Guim. & Michelang., but is readily distinguished by shorter leaf blades 15–44 mm long (versus 40–55 mm long in P. formosum), cyme inflorescences (vs. thyrsoids), 1–5 flowers per inflorescence (vs. 35–58 flowers per inflorescence), bracteoles 10–17.5 × 6.5–10 mm (vs. 4–6 × 1.4–2 mm), sepals 4–6 mm long (vs. 2.5–2 mm long). Etymology: The specific epithet, barbellatum, refers to shortly barbed trichomes (see Beentje 2016) that are easily observed on branches, leaves, pedicels, bracts and bracteoles, hypanthia, outer surface and margins of sepals, and base of the style (see Figures 1B and 2).

| 8:15a | [Botany • 2024] Syzygium ngheanense (Myrtaceae: Syzygieae) • A New Species from Central Vietnam
Abstract Syzygium ngheanense (Myrtaceae), a new species from Nghe An Province, in Central Vietnam is described and illustrated. The species is most similar to S. vestitum, S. scarbum and S. levinei but differs from the three latter in having glabrous bracts and bracteoles, sparsely scabrid flower buds and hypanthia, larger sepals and petals, longer stamens and styles. Information on phenology, ecology and distribution is provided, together with a preliminary conservation status assessment and taxonomic notes for the new species and a key to distinguish it from three hairy Syzygium species in Indochina.

| 1:42p | [Crustacea • 2024] Phalangipus somnathensis • A New Species of Spider Crab from India, Arabian Sea, with A Key to the Species of Phalangipus Latreille, 1828 (Decapoda: Brachyura: Epialtidae)
Abstract A new species of spider crab is described based on a single specimen collected from the Veraval fishing harbour, Gujarat, north-west coast of India, Arabian Sea. Globally nine species of spider crabs were reported of which four, Phalangipus filiformis, P. hystrix, P. indicus and P. longipes were documented from Indian waters. The new species, P. somnathensis sp. nov. differs from most species of the genus, based on the presence of blunt spines over the lateral & dorsal margin of the carapace, by the intestinal region being produced into a sharp spine, and by possessing a unique shape of male pleopod, i.e., branched into two lobes distally. The newly discovered species is compared with its congeners. Keywords: Epialtidae; Gujarat; new discovery; Phalangipus somnathensis sp. nov.; pleopod;   B. Sureandiran, K. Karuppasamy and N. K.

| 1:42p | [Arachnida • 2024] Maimuna antalyensis, Tegenaria beyazcika, T. egrisiana, ... • New Taxonomic and Faunistic Data on the Funnel-weavers (Araneae: Agelenidae) of Turkiye and the Caucasus, with Five New Species
Abstract New taxonomic and faunistic data on the agelenid spiders of Turkiye and the Caucasus are provided. Five species are described as new to science: Maimuna antalyensis sp. nov. (♂♀; Turkiye: Antalya), Tegenaria ballarini sp. nov. (♂♀; Turkiye: Antalya), T. beyazcika sp. nov. (♂; Turkiye: Antalya), T. egrisiana sp. nov. (♂♀; Georgia: Imereti), and T. hoeferi sp. nov. (♂♀; Armenia: Kotayk). Tegenaria lazarovi Dimitrov, 2020, syn. nov. is proposed as a new junior synonym of T. averni Brignoli, 1978. Persiscape caucasica (Guseinov, Marusik & Koponen, 2005) is newly reported from Armenia, and T. chumachenkoi Kovblyuk & Ponomarev, 2008 is reported for the first time from Turkiye. New distribution records for T. dalmatica Kulczyński, 1906, T. hamid Brignoli, 1978, T. longimana Simon, 1898 and T. percuriosa Brignoli, 1972, and topotype material for T. tekke Brignoli, 1978 are reported. The record of Eratigena fuesslini (Pavesi, 1873) from Turkiye is found to be based on a misidentification, and is herein attributed to T. hamid. The presence of an embolic spine, unknown in any other species of Tegenaria, is documented in T. anhela Brignoli, 1972 for the first time. Photographs are provided for all treated species. Key words: Anatolia, Armenia, Georgia, Maimuna, new record, new synonymy, Persiscape, Tegenaria

| 1:43p | [Botany • 2024] Ornithogalum christiniae (Asparagaceae) • A New Species from an offshore islet on the Cretan Area (S. Aegean, Greece)
Abstract Ornithogalum christiniae sp. nov., collected from the offshore islet of Agria Gramvousa (northwestern Crete, Greece), is described and illustrated as a locally endemic species. It is related to Ornithogalum montanum, O. atticum and O. pumilum, however, it differs from these in having wrinkled and corrugated leaf surface, fruiting pedicels thickened at base, flexuose rachis of infructescence and winged capsules. The relationships between the new species and the aforementioned are discussed, while information regarding its ecology, conservation status and karyotype is also given. Keywords: Aegean Flora, island specialists, karyotypes, new species, Ornithogalum, taxonomy
Ornithogalum christiniae sp. nov. Diagnosis: A species showing some similarities with O. montanum, and to a lesser extent with O. atticum and O. pumilum, in having bulbs with concrescent scales, leaves more than 5 mm wide without a white stripe, a short raceme that is corymbiform at anthesis, entire filaments and hypogeal germination, however, it differs from these three species in having spherical to sub-spherical bulbs, wrinkled and corrugated leaf surface, basally thickened fruiting pedicel and winged capsules. Etymology: The species epithet is dedicated to Dr Christini Fournaraki, Mediterranean Agronomical Institute of Chania (CIHEAM-MAICh), a well-known botanist and fellow in fieldwork.
