| 12:42a | [Herpetology • 2022] Scinax albertinae • A New Snouted Treefrog of the Genus Scinax (Anura, Hylidae) from the White-Sand Forests of Central Amazonia
Abstract We describe through integrative taxonomy a new species of snouted treefrog of the genus Scinax from white-sand forests of the Rio Negro Sustainable Development Reserve in Central Amazonia, Brazil. The new species is phylogenetically related to other Scinax with striped eyes and pulsed advertisement calls. It differs from other Amazonian species mainly by having snout–vent length 21.6–25.4 mm (n= 11) in adult males and 24.8–27.0 mm (n= 9) in females, snout subacuminate in dorsal view, a dark brown lateral stripe on each flank (fading posteriorly), brown tadpoles with labial keratodont row formula 2(2)/3 and keratodont row P-2 longer than P-1 and P-3, and an advertisement call consisting of a single pulsed note with a call duration of 502–652 ms, 79–105 pulses/note and a dominant frequency of 3,811–4,543 Hz. The new species clusters within a major, well-supported phylogenetic clade grouping several candidate and recently described species as well as species previously included in the former Scinax staufferi species group (viz., S. cruentomma, S. fuscomarginatus, S. staufferi, and S. wandae). The phylogenetic relationships and structural pattern in the advertisement calls of these species highlight the need for a redefinition and reevaluation of the monophyly of the S. staufferi species group.

| 12:44a | [Botany • 2021] Artabotrys sericeus (Annonaceae) • A New Species of Artabotrys from the southern Western Ghats, India
ABSTRACT A new species, Artabotrys sericeus Sujana & Vadhyar, is described from Tamil Nadu, India. The new species shows some resemblance to Artabotrys zeylanicus Hook.f. & Thomson, but it can be easily distinguished by the shape, size, colour and indumentum of the petals as well as the shape and texture of the monocarps. Illustrations, photographs and SEM images of the pollen grains of the new species are provided. The conservation status of the new species is also assessed. Keywords.

Artabotrys sericeus Sujana & Vadhyar, sp. nov. Distribution and ecology. The species is so far known only from Kanyakumari Wildlife Sanctuary, Tamil Nadu, South India. It grows in tropical semi-evergreen forests and tropical moist deciduous forests at an altitudinal range between 500 m and 900 m. The major associate species noted are Albizia amara (Roxb.) Boivin, Aporosa indoacuminata Chakrab. & N.P.Balakr., Archidendron bigeminum (L.) I.C.Nielsen, Erycibe paniculata Roxb., Machilus glaucescens (Nees) Wight, Olea dioica Roxb., Premna tomentosa Willd. and Xanthophyllum arnottianum Wight. Etymology. The specific epithet ‘sericeus’ refers to the densely sericeous petals. K.A. Sujana and R.G. Vadhyar. 2021. A New Species of Artabotrys (Annonaceae) from the southern Western Ghats, India.

| 3:47a | [Botany • 2022] Begonia kapuashuluensis, B. patar & B. sangkulirangensis (Begoniaceae) • Three New Species, One New Record and An Updated Checklist of Begonia from Kalimantan, Indonesia
Abstract Three new Begonia species from Kalimantan, Indonesian Borneo are described here, namely Begonia kapuashuluensis, B. patar and B. sangkulirangensis, and one species is reported as a new record for Kalimantan. Colour plates, as well as notes on distribution, habitat and conservation status are provided. On conservation status, we provisionally assess B. kapuashuluensis as near threatened, B. patar as critically endangered and B. sangkulirangensis as vulnerable.

| 11:16a | [Botany • 2022] Miliusa microphylla (Annonaceae) • A New Species from Thailand as evidenced by Morphology and Plastid Phylogeny, with M. glandulifera, A New Record for Thailand
Abstract On the basis of expansive molecular phylogenetic analyses of the genus Miliusa (Annonaceae) utilising up to seven plastid DNA regions, four major clades are identified: clades A, B, C and D. Members of clade C possess axillary inflorescences and crescent-shaped to semicircular glandular structures at the base or (slightly) higher inside the inner petals. In this clade, accessions of M. mollis are recovered as a monophyletic group, divided into two major clades. One of them is recognised as a new species, M. microphylla, which differs from the other (M. mollis) in the following characters: pedicel length, as well as glandular structures and indumentum on the inner petals. The new species is endemic to southeastern Thailand, whereas M. mollis has a much wider distribution (central, eastern, northeastern, northern and peninsular Thailand plus Cambodia and Vietnam). In addition, M. glandulifera, a new record for Thailand, is retrieved as the sister group of a clade composed of M. microphylla and M. mollis. The name M. glandulifera is lectotypified and the description of M. glandulifera is emended, with the information on mature monocarps added. The conservation status of M. microphylla and M. glandulifera is provisionally assessed. A revised key to the species in clade C in Thailand is provided. The phylogenetic position of M. nakhonsiana and M. sessilis in clade C, as well as of M. chantaburiana and M. eupoda in clade B is confirmed for the first time.

| 11:17a | [Herpetology • 2021] Boaedon mendesi • Taxonomic Revision of the Jita Snakes (Serpentes: Lamprophiidae: Boaedon) from São Tomé and Príncipe (Gulf of Guinea), with the Description of A New Species
ABSTRACT The taxonomic status of the São Tomé and Príncipe islands ‘Cobras Jitas’, genus Boaedon, has been a subject of confusion. Historically, these island populations have been referred to as part of either the Boaedon fuliginosus species complex or Boaedon capensis species complex, two of the most taxonomically challenging groups of African snakes, or considered a distinct taxonomic entity, B. bedriagae. Here we review the São Tomé and Príncipe populations through a combination of morphological and molecular data. Our results suggest that each island population represents a unique species. After a thorough review of the taxonomic and nomenclatural history of the group, we revalidate B. bedriagae, restricting the application of this name to the São Tomé population by the designation of a lectotype. We also describe the Príncipe population as a new species, Boaedon mendesi sp. nov. This description has implications to our understanding of the diversity and phylogeographic patterns of the Gulf of Guinea Oceanic Islands. KEY WORDS: Boaedon bedriagae, Boaedon mendesi sp. nov., Boaedon fuliginosus complex, endemism, island biodiversity
