| 9:04a | [Ichthyology • 2022] Tatia luisae • A New Species of Driftwood Catfish of Tatia (Siluriformes: Auchenipteridae) from rio Tapajós, Brazil
Abstract A new species of Tatia is described from rio Tapajós, upstream of the rapids of São Luiz do Tapajós, Pará State, Brazil. The new species is identified and diagnosed from its congeners through morphological characteristics such as the absence of an adipose fin, which is shared with T. akroa and T. britskii; the composition of the cranial roof elements; the color pattern consisting of dorsolateral dark dots formed by both dermal and epidermal pigments; as well as several morphometric measures. The new species is a Centromochlinae fish that feeds on insects on the surface of the water at night and it is probably endemic to rio Tapajós basin. Keywords: Amazonia, Biodiversity, Centromochlinae, Freshwater fishes, Taxonomy.
Tatia luisae, new species Diagnosis. Tatia luisae differs from all species of Tatia and Centromochlus, except T. akroa Souza, Sarmento-Soares, Canto & Ribeiro, 2020 and T. britskii Sarmento-Soares & Birindelli, 2015, by the absence (vs. present) of adipose fin. Tatia luisae differs from T. akroa by the dorsal-fin spine length (16.4–24.3% SL, mean 19.6 vs. 12.3–17.3% SL, mean, 14.7), head depth (56.4–71.9% HL, mean 66.3 vs. 40.6–57.6% HL, mean 47.2), interorbital distance (34.7–45.0% HL, mean 4.0 vs. 46.1–57.9% HL, mean 50.2), and posterior internarial distance (22.1–30.2% HL, mean 25.7 vs. 30.0–38.2% HL, mean 33.3). Tatia luisae differs from T. britskii by the body depth (17.8–24.6% SL, mean 22.6 vs. 14.6–17.1% SL, mean 16.2), dorsal-fin spine length (16.3–24.3% SL, mean 19.7 vs. 13.3–15.6% SL, mean 14.3), head depth (56.4–71.9% HL, mean 66.3 vs. 46.3–52.7% HL, mean 49.5), anterior internarial distance (14.6–24.2% HL, mean 21.9 vs. 29.2–33.0% HL, mean 31.2), and posterior internarial distance (22.1–30.2% HL, mean 25.7 vs. 31.5–34.7% HL, mean 33.5). Tatia luisae further differs from T. aulopygia (Kner, 1857), T. altae (Fowler, 1945), T. brunnea, T. caudosignata DoNascimiento, Albornoz-Garzón & García-Melo, 2019, T. dunni (Fowler, 1945), T. ferrarisi (Birindelli, Sarmento-Soares & Lima, 2015), T. galaxias Mees, 1974, T. gyrina (Eigenmann & Allen, 1942), T. intermedia, T. jacaratia Pavanelli & Bifi, 2009, T. meesi Sarmento-Soares & Martins Pinheiro, 2008, T. meridionalis, T. neivai (Ihering, 1930), T. perugiae (Steindachner, 1882), T. punctata Mees, 1974, T. reticulata Mees, 1974 and T. strigata Soares-Porto, 1995 by dotted color pattern on sides of body (vs. mottled, spotted or reticulated on flanks). Differs from T. aulopygia, T. boemia Koch & Reis, 1996, T. brunnea, T. caxiuanensis Sarmento-Soares & Martins-Pinheiro, 2008, T. caudosignata, T. dunni, T. galaxias, T. gyrina, T. intermedia, T. jaracatia, T. meesi, T. neivai, T. nigra, and T. strigata by the absence (vs. presence) of anterior nuchal plate. Geographical distribution. Tatia luisae is currently known only from the middle rio Tapajós, upstream of the rapids of São Luiz do Tapajós, at Itaituba Municipality (Fig. 6). Etymology. The specific epithet luisae is in honor to the Brazilian ichthyologist Luisa M. Sarmento-Soares, in recognition of her many contributions to the systematics of Neotropical catfishes of the subfamily Centromochlinae. A noun in the singular genitive case.  Frank Raynner V.

| 11:28a | [Herpetology • 2022] Taxonomy and Distribution of A Common Arboreal Lizard, Bronchocela jubata Duméril & Bibron, 1837 (Reptilia: Agamidae), with Designation of Its Lectotype from Java, Indonesia
Abstract Bronchocela jubata Duméril and Bibron, 1837 is one of the commonest species of the genus, known mostly from Java Island and southern parts of Sumatra. It is rare in Bali and Borneo. The juveniles are often confused with its morphologically similar congener, B. cristatella, which occurs widely throughout the Indonesian Archipelago and Peninsular Malaysia. We examined the morphology of B. jubata based on museum specimens including its two available syntypes, and redescribed the species based on the lectotype designated herein. We highlight the characters of B. jubata with a morphometric comparison to its sympatric congener B. cristatella from Java Island, Indonesia. Based on the current distribution pattern and the apparent threats, we update the conservation status of B. jubata using IUCN Red List Criteria, and propose that it be considered as a species of Least Concern (LC), endemic to the Greater Sundaic Islands.

| 1:11p | [Herpetology • 2022] Systematic Position of the Clicking Frog (Kassinula Laurent, 1940), the Problem of Chimeric Sequences and the Revised Classification of the Family Hyperoliidae
Highlights: • Phylogeny and systematics of the African frog family Hyperoliidae. • Kassinula included for the first time in a multilocus phylogenetic reconstruction. • Kassinula merits the genus-level status. • Chimeric sequences are phylogenetically placed at misleading positions. • Revised suprageneric taxonomy of the Hyperoliidae. Abstract The systematics of the African frog family Hyperoliidae has undergone turbulent changes in last decades. Representatives of several genera have not been genetically investigated or with only limited data, and their phylogenetic positions are thus still not reliably known. This is the case of the De Witte's Clicking Frog (Kassinula wittei) which belongs to a monotypic genus. This miniature frog occurs in a poorly studied region, southeastern Democratic Republic of the Congo, northern Zambia, Angola. So far it is not settled whether this genus belongs to the subfamily Kassininae as a relative of the genus Kassina, or to the subfamily Hyperoliinae as a relative of the genus Afrixalus. Here we present for the first time a multilocus phylogenetic reconstruction (using five nuclear and one mitochondrial marker) of the family Hyperoliidae, including Kassinula. We demonstrate with high confidence that Kassinula is a member of Hyperoliinae belonging to a clade also containing Afrixalus (sub-Saharan Africa), Heterixalus (Madagascar) and Tachycnemis (Seychelles). We find that Kassinula represents a divergent lineage (17–25 Mya), which supports its separate genus-level status, but its exact systematic position remains uncertain. We propose to name the clade to which the above four genera belong as the tribe Tachycnemini Channing, 1989. A new taxonomy of the family Hyperoliidae was recently proposed by Dubois et al. (2021: Megataxa 5, 1–738). We demonstrate here that the new taxonomy was based on a partially erroneous phylogenetic reconstruction resulting from a supermatrix analysis of chimeric DNA sequences combining data from two families, Hyperoliidae and Arthroleptidae (the case of Cryptothylax). We therefore correct the erroneous part and propose a new, revised suprageneric taxonomy of the family Hyperoliidae. We also emphasize the importance of inspecting individual genetic markers before their concatenation or coalescent-based tree reconstructions to avoid analyses of chimeric DNA sequences producing incorrect phylogenetic reconstructions. Especially when phylogenetic reconstructions are used to propose taxonomies and systematic classifications.
