| 1:26a | [Entomology • 2022] Skejotettix netrajyoti • A New Genus and A New Groundhopper Species (Orthoptera: Tetrigidae) from Nepal
Abstract This paper describes one new genus from Nepal, Skejotettix gen. nov., and one new species of this new genus, S. netrajyoti gen. et sp. nov. and assigns one species to this new genus, S. muglingi (Ingrisch, 2001b) comb. nov. from Coptotettix Bolívar, 1887. The genus is morphologically close to Ergatettix Kirby, 1914 from Nepal, Lamellitettigodes Günther, 1939 from SE Asia, and Hainantettix Deng, 2020 (including H. angustivertex (Zha et Peng, 2021) comb. nov. and H. hainanensis (Liang, 2002) comb. nov.) from Hainan, China. New distribution records have been provided to Coptotettix. Endemic to Nepal, the genus Skejotettix gen. nov. shares two different habitat types (subtropical Sal forest for S. netrajyoti gen. et sp. nov., and river/stream/pond bank for S. muglingi (Ingrisch, 2001b) comb. nov.).

| 2:54a | [Botany • 2022] Andinia peruviana (Orchidaceae: Pleurothallidinae) • A New Species of Andinia from Peru and An updated Phylogenetic Analysis of the Genus with Emphasis on Subgenus Aenigma
Abstract A new species, Andinia peruviana, from Amazonas department, Peru, is described and illustrated. Updated phylogenetic analyses of nuclear internal transcribed spacer (nrITS) sequences in this study re-affirm the monophyletic nature of Andinia sensu lato and further support the previously proposed circumscription which incorporated genera Lueranthos, Masdevalliantha, Neooreophilus, and Xenosia. Andinia subgenus Aenigma was strongly supported in all analyses. The new species was determined phylogenetically to belong to subgenus Aenigma, along with A. barbata, A. dalstroemii, A. hirtzii, A. pogonion, A. schizopogon and A. uchucayensis. The phylogenetically-confirmed representatives of subgenus Aenigma are illustrated with drawings and photographs, and their geographic distribution is discussed. The updated phylogenetic analyses also show the corrected phylogenetic positions of A. vestigipetala, as the sole representative of the clade corresponding to subgenus Minuscula, and A. trimytera, as a member of the clade corresponding to subgenus Andinia. Keywords: Aenigma species, endemic species, montane forests, neotropics, phylogeny, taxonomy  Andinia peruviana Ocupa, S.Vieira-Uribe & Mark Wilson, sp. nov. Diagnosis: Andinia peruviana is most similar to Andinia schizopogon (Luer) Pridgeon & M.W.Chase (Fig. 6) but differs in the lateral sepals connate for ca. ⅔ of its length (vs. connate to less than ½ of their length), covered with hairs up to 5 mm long (vs. longpubescent-spiculate), with strongly revolute sides (vs. revolute sides), petals with tortuous cilia on the margins (vs. microscopically irregular margins), the apical mid-lobe of the lip with lacerate to filiform-papillose margins (vs. shortly muriculate), basal lobes of the lip with papillose margins (vs. entire margins). Etymology: The specific name is in reference to the country where the type was first collected, Peru. Luis Ocupa-Horna, Sebastián Vieira-Uribe, Raven Ward, Caroline Brose and Mark Wilson. 2022.

Se describe e ilustra una nueva especie de Andinia, A. peruviana, procedente del departamento de Amazonas, Perú. Los análisis filogenéticos actualizados de las secuencias del espaciador transcrito interno nuclear (nrITS) en este estudio reafirman la naturaleza monofilética de Andinia sensu lato y apoyan aún más la circunscripción propuesta anteriormente que incorporaba los géneros Lueranthos, Masdevalliantha, Neooreophilus y Xenosia. El subgénero Aenigma de Andinia recibió un fuerte apoyo en todos los análisis. Se determinó que la nueva especie pertenece filogenéticamente al subgénero Aenigma, junto con A. barbata, A. dalstroemii, A. hirtzii, A. pogonion, A. schizopogon y A. uchucayensis. Los representantes del subgénero Aenigma confirmados filogenéticamente se ilustran con dibujos y fotografías y se discute su distribución geográfica. Los análisis filogenéticos actualizados también muestran las posiciones filogenéticas corregidas de A. vestigipetala, como único representante del clado correspondiente al subgénero Minuscula, y de A. trimytera, como miembro del clado correspondiente al subgénero Andinia. | ||||||
| 4:36p | [Herpetology • 2022] Mantidactylus incognitus , M. riparius, M. manerana, etc. • An inordinate fondness for inconspicuous brown frogs: Integration of Phylogenomics, Archival DNA Analysis, Morphology, and Bioacoustics yields 24 New Taxa in the Subgenus Bry
Abstract Malagasy frogs of the subgenus Brygoomantis in the mantellid frog genus Mantidactylus currently comprise 14 described species of mostly brown, riparian frogs. Data from DNA barcoding suggested that the diversity of this subgenus is dramatically underestimated by current taxonomy. We here provide a comprehensive revision of this subgenus. We use hybrid-enrichment based DNA barcode fishing to obtain mitochondrial DNA fragments from the name-bearing type material of 16 of the 20 available names for members of this subgenus, and integrate these into a genetic dataset consisting of 1305 individuals sampled across Madagascar. By thus assigning the nomina to genetic lineages, we can confidently establish synonyms, revalidate old names, and describe the remaining diversity. We take an integrative approach to our descriptions, drawing together genetics, morphometrics and morphology, and bioacoustics for assignment. We also provide a robust phylogenomic hypothesis for the subgenus, based on 12,951 nuclear-encoded markers (almost 10 million base pairs) for 58 representative samples, sequenced using a hybrid-enrichment bait set for amphibians. Those data suggest a division of the subgenus into eight major clades and shows that morphological species complexes are often paraphyletic or polyphyletic. Lectotypes are designated for Rana betsileana Boulenger, 1882; Rana biporus Boulenger, 1889; Rana curta Boulenger, 1882; Mantidactylus ambohimitombi Boulenger, 1918; Mantidactylus tripunctatus Angel, 1930; and Rana inaudax Peracca, 1893. For several other nomina, previous authors had considered a certain syntype as holotype; this has been seen as lectotype designation by implication, which, however, is ambiguous according to the provisions of the International Code of Zoological Nomenclature. Hence, we validate a previous lectotype designation by implication for Limnodytes ulcerosus Boettger, 1880 by explicitly designating the same individual as lectotype. In one other such case, that of Mantidactylus brauni Ahl, 1929, we deviate from previous authors and designate a different specimen as lectotype. We revalidate Rana inaudax Peracca, 1893 as Mantidactylus inaudax (Peracca, 1893) bona species, and Mantidactylus tripunctatus Angel, 1930 bona species. The identities of three further species (M. ambohimitombi, M. biporus, M. tricinctus) are largely redefined based on new genetic data. By designating the lectotype of Rana aluta (MZUT An725.1) as the neotype of Mantidactylus laevis Angel, 1929 we also stabilize the latter nomen (as junior synonym of M. alutus) whose original type material is lost. Based on DNA sequences of its lectotype, we consider Mantidactylus brauni Ahl, 1929 as junior synonym of M. ulcerosus (rather than M. biporus). We formally name 20 new species and four new subspecies: Mantidactylus ambohimitombi marefo ssp. nov., M. ambohimitombi miloko ssp. nov., M. mahery sp. nov., M. steinfartzi sp. nov., M. incognitus sp. nov., M. jonasi sp. nov., M. katae sp. nov., M. kortei sp. nov., M. riparius sp. nov., M. fergusoni sp. nov., M. georgei sp. nov., M. jahnarum sp. nov., M. marintsoai sp. nov., M. grubenmanni sp. nov., M. gudrunae sp. nov., M. augustini sp. nov., M. bletzae sp. nov., M. brevirostris sp. nov., M. eulenbergeri sp. nov., M. glosi sp. nov., M. stelliger sp. nov., M. manerana sp. nov., M. manerana fotaka ssp. nov., and M. manerana antsanga ssp. nov. Based on our taxonomic revision, we discuss (i) the importance of definitive assignment of historical names via archival DNA analysis; (ii) the relevance of the subspecies category to name geographic variation within species; (iii) the value of molecular characters in formal species diagnoses in taxa with substantial individual variation of morphology; (iv) the use of phylogenomic approaches for taxonomy, by confirming that some morphologically similar taxa are not each other’s closest relatives, and in several cases belong to entirely different major subclades within Brygoomantis, thus facilitating lineage diagnosis; and (v) the need to interpret genetic distances in a probabilistic framework rather than using fixed thresholds, where higher distances confer a higher likelihood of genetic incompatibilities across the genome and thus completion of speciation.
