| 10:05a | [Herpetology • 2016] Scinax haddadorum • A New Species of Scinax Wagler (Anura: Hylidae) from Mato Grosso, Brazil
Abstract A new species of the Scinax ruber Clade is described from Municipality of Barra do Garças, State of Mato Grosso, Brazil. It is diagnosed by its size (SVL 29.4–35.4 mm in males); dorsum with a background that varies from light and dark gray to dark brown, with round and irregular dark blotches; hidden surfaces of thigh and shank light or dark brown, with lighter, large and irregular blotches (yellow in life); and nuptial pad that covers the medial margin of Metacarpal I, and obscures the posterior portion and the outer margin of the inner metacarpal tubercle. It is most similar with Scinax rupestris, from which it differs by having larger adult males; less developed nuptial pad; and hidden surfaces of thigh and light or dark brown, with lighter, large and irregular blotches (yellow in life). The new species occurs near the headwaters of permanent or temporary streams, where males call from vegetation or rocks at the margins of small streams.

| 10:25a | [Botany • 2022] Nicotiana gandarela (Solanaceae) • A New Species of ‘Tobacco’ highly Endangered from the Quadrilátero Ferrífero in Brazil
Abstract Nicotiana gandarela Augsten & Stehmann (Solanaceae), sp. nov., a small ’tobacco’ known only from one locality at Serra do Gandarela, in the state of Minas Gerais, Brazil, is described and illustrated. It is morphologically characterized by its rosulate basal leaves, red corolla with a short tube not inflated at the apex, and the peculiar habitat, a shaded site under a rocky outcrop ledge along a forested stream. Phylogenetic analyses based on a combined dataset of nuclear (ITS) and plastid (ndhF, trnLF, and trnSG) DNA sequences revealed that the species belongs to the Nicotiana sect. Alatae and is sister to the clade with the remaining species in the section. A key for the identification of Brazilian species of the section is given. The unusual habitat, the small population size, and the intense pressure of mining activities in the surroundings made the species assessed as Critically Endangered (CR), needing conservation efforts to avoid its extinction. Keywords: Endemism, IUCN, Minas Gerais, mining, molecular phylogeny
 Nicotiana gandarela Augsten & Stehmann, sp. nov. Diagnosis: Nicotiana gandarela differs from all other species of the Nicotiana sect. Alatae by its short corolla tube (< 15 mm), vivid red corolla limb, and unusual shaded, cave-mouth habitat. Etymology: The specific epithet “gandarela” is a noun in apposition and refers to Serra do Gandarela, the mountain range complex where this species is found.

| 4:01p | [Herpetology • 2022] Taxonomic Composition of the Oligodon arnensis (Shaw 1802) Species Complex (Squamata: Colubridae) with the Description of Oligodon tillacki, A New Species from India
Abstract We review the taxonomic status of Oligodon arnensis (Shaw 1802) after examining all the name-bearing types of its synonyms, and evaluating morphological and biogeographic evidence. Oligodon arnensis sensu lato is widely distributed throughout Peninsular India, Sri Lanka, Pakistan, Nepal, Bhutan, and Bangladesh. We demonstrate that southern, eastern, and western populations in India represent three distinct species. Oligodon arnensis sensu stricto described from Arnee (now Arani), Tamil Nadu, southern India, is distributed in southern India up to 1500 m above sea level. Oligodon albiventer Günther 1864 and Simotes russellii var. ceylonensis Müller 1887 described from Sri Lanka closely match O. arnensis sensu stricto, and hence we treat them as junior synonyms. We resurrect Coluber russelius Daudin 1803 from the synonymy of O. arnensis, designate a lectotype, and restrict its type locality to Vizagapatam (now Visakhapatnam), Andhra Pradesh, eastern Peninsular India. Based on morphological differences we describe a new species from Kurduvadi, in the Deccan plateau of western India representing the western Indian population of O. arnensis sensu lato. We provide redescriptions for O. arnensis sensu stricto and O. russelius comb. nov. based on museum specimens, as both were named based on illustrations (iconotypes). Based on our update of the currently confirmed localities for O. arnensis, O. russelius comb. nov. and the new species, we discuss their biogeography and conservation status.      Sanjaya K.
