| 2:37a | [Ichthyology • 2024] Cyphocharax albiventris • A New Species of Cyphocharax Fowler (Characiformes: Curimatidae) from the Rio Xingu, Brazil
Abstract A new species of the curimatid genus Cyphocharax is described from the Rio Xingu, Amazon basin. This species is readily distinguished from congeners by the presence of a dark, round blotch on the caudal peduncle and by the high density of iridophores on the ventrolateral portion of the body, resulting in a strongly countershaded pattern. Molecular phylogenetic analyses support the recognition of the new species and suggest that it is nested within the Curimatella alburna clade. Ancestral state reconstruction suggests independent evolutionary origins of the blotched caudal peduncle and the countershaded ventrolateral flanks among curimatid fishes.

| 3:08a | [Diplopoda • 2020] Syrioiulus lohmanderi • A New Species of Syrioiulus Verhoeff, 1914 (Julida: Julidae) from Iran, with Remarks on the Taxonomy of the Genus
Abstract Syrioiulus lohmanderi sp. nov. is described from material collected in Gilan Province, northwestern Iran. The new species is morphologically most similar to S. astrabadensis (Lohmander, 1932a) and S. persicus (Golovatch, 1983), also known only from the northern parts of Iran. A key to the species of SyrioiulusVerhoeff, 1914 recorded from this country is compiled, and a checklist of all species presently assigned to the genus is given. Syrioiulus adsharicus (Lohmander, 1936) and S. cappadocius (Lohmander, 1939) are transferred from Amblyiulus Silvestri, 1896. The taxonomic problems within Syrioiulus and related genera are briefly discussed.

| 3:15a | [Botany • 2020] Chamaelirium shimentaiense (Melanthiaceae) • A New Species from Guangdong, China
Abstract Chamaelirium shimentaiense (Melanthiaceae), a new species from Shimentai Nature Reserve, Guangdong Province, China is described. This species is similar to C. shiwandashanense and C. viridiflorum in having actinomorphic flowers with six tepals and unilocular anthers, but is easily distinguished from them by its strongly undulate leaf blades with crispulate margins and inconspicuous venation, purplish tepals with a slightly broadened and obtuse apex, and purple-tinged filaments. The infrageneric assignment of this species is discussed and a color plate is provided.

| 9:13a | [Crustacea • 2024] Mexicope maletensis • A New Species of Mexicope Hooker, 1985 (Isopoda) — the First Record of Acanthaspidiidae Menzies, 1962 from the Mediterranean Sea
Abstract Background: The marine isopod family Acanthaspidiidae Menzies, 1962 (Asellota, Janiroidea) has global distribution from shelf to hadal depth. The majority of species has been recorded from relatively deep waters and the Southern Hemisphere. To date, 36 species have been described in the family belonging to three genera: Ianthopsis Beddard, 1886; Iolanthe Beddard, 1886; and Mexicope Hooker, 1985. New information: Here, a new species of Mexicope is described from Maltese waters, adding a fourth species to the genus. It is the first member of the family reported from the Mediterranean Sea. The new species can be recognised by the unique combination of the following characters: cephalothorax with pre-ocular spine large and pointed anterolaterally, rostral projection blunt, eyes reduced; pereonal sternites each with one ventral spine; pereonite two lateral margins with single projection; pleotelson posterior apex long, projecting to approximately half of the length of the uropod protopod; pleopods I distolateral lobes projecting beyond distomedial lobes, apices curved and pointed laterally; uropod exopod length approximately 0.5 endopod length. An identification key to the species of Mexicope is presented and the generic diagnoses of Ianthopsis and Mexicope are compared, discussed and revised.

| 3:19p | [Botany • 2024] Thismia malayana (Thismiaceae) • A New Species of Thismia sect. Odoardoa from Peninsular Malaysia
Abstract A new species of the mycoheterotrophic genus Thismia from Malaysia is described and illustrated. Thismia malayana introduced here was found in two localities: in the lowlands of Gunung Angsi Forest Reserve, Negeri Sembilan, and in the hilly dipterocarp forests of Gunung Benom in Tengku Hassanal Wildlife Reserve, Pahang. Thismia malayana falls into the section Thismia subsect. Odoardoa, as it has creeping vermiform roots and free equal tepals. It is characterised by the following taxonomically important features: a sepia-brown, urceolate-curved floral tube, free equal tepals with terminal appendages, prominent bright yellow annulus and bright violet-blue stamens each bearing five appendages (one pair of club-shaped inwards-pointing, one pair of acute outwards-pointing, and one central appendage). According to the categories and criteria of the IUCN Red List, T. malayana is provisionally classified as Vulnerable. Key words: Negeri Sembilan, new species, Pahang, Thismia subsect. Odoardoa, Vulnerable
Thismia malayana Siti-Munirah, Hardy-Adrian, Mohamad-Shafiq & Irwan-Syah, sp. nov. Diagnosis: Thismia malayana resembles T. chrysops but differs by the brown-whitish colour of the floral tube (vs. very dark sepia brown), glabrous surface of the tepal appendages (vs. finely ciliate), presence of transverse bars at inner surface of floral tube (vs. bars absent), supraconnective apex of each stamen with 5 appendages: one pair of club-shaped inwards-pointing, one pair of acute outwards-pointing, and one central appendage (vs. 7 appendages: one pair of club-shaped, one pair of acute and 3 central appendages). Etymology: The specific epithet malayana is derived from Malaya, a name formerly used for Peninsular Malaysia. The epithet refers to the known region of the species distribution.
