| 3:22a | [Botany • 2021] Funastrum saganii (Apocynaceae: Asclepiadoideae: Oxypetalinae) • A New Species endemic to Veracruz, Mexico
ABSTRACT A new species of Funastrum is described from Veracruz, Mexico. Although Funastrum saganii sp. nov. is morphologically similar to F. elegans and F. lindenianum, there are differences in leaf and flower morphology and geographic distribution. Descriptions, illustrations and the geographic distribution of this species are provided, and its conservation status discussed. Morphological leaf analysis was performed using geometric morphometrics. This discovery highlights Mexico as center of diversity for the genus Funastrum, with 14 of its 19 species located in the country. This finding is important because it is the first new species of Funastrum to be described from Mexico in 127 years. Keywords: Apocynaceae; endemism; Funastrum; geometric morphometrics; Oxypetalinae; Veracruz; Mexico
Funastrum saganii M.G. Chávez, Lozada-Pérez & L.O. Alvarado sp. nov. Funastrum saganii is morphologically similar to F. elegans and F. lindenianum in the flower size and their ovate corolla lobes but differs from those taxa by its ovate leaves with a convergent base and by presenting more than 12 flowers per inflorescence. Also, the geographical distribution and altitude are different (Figs. 3, 4, 5). Distribution and habitat: Funastrum saganii is distributed in the state of Veracruz, in tropical dry forest and perturbed areas derived thereof, growing from 500 to 550 m a.s.l. (Fig. 5). Etymology: The name honors Carl Edward Sagan (1934 – 1996), who was an American astronomer, cosmologist, astrophysicist, astrobiologist, science disseminator, and science communicator in astronomy and other natural sciences.

| 2:30p | [Arachnida • 2021] Chthonius kirghisicus • A New Cave-dwelling Species (Pseudoscorpiones, Chthoniidae) from Kyrgyzstan
Abstract A new pseudoscorpion species, Chthonius kirghisicus sp. nov., is described. It can be distinguished from the other species of the genus mainly by the number and shape of chelal teeth, the number of coxae setae, the arrangement of carapacal setae, and its measurements. This new species represents the first record for the genus in Kyrgyzstan. We also provide recommendations for future research on this species. Keywords: Cave-dwelling, pseudoscorpion, taxonomy

| 2:35p | [Mollusca • 2021] Jorunna artsdatabankia • The Genus Jorunna (Nudibranchia: Discodorididae) in Europe: A New Species and A possible Case of Incipient Speciation
ABSTRACT To investigate the conspecificity of different morphotypes of Jorunna tomentosa (Cuvier, 1804) (type species of genus Jorunna Bergh, 1876), we studied specimens sampled from across part of the geographical distribution of the species, using a combination of morphoanatomical characters and molecular phylogenetics. Bayesian and maximum likelihood phylograms were inferred based on the mitochondrial genes cytochrome c oxidase subunit I (COI) and 16S ribosomal RNA, and the nuclear gene histone H3. We used the automatic barcode gap discovery method to aid in species delimitation. COI genetic uncorrected p-distances were estimated between and within species. Animals were dissected and the reproductive system, radulae and labial cuticles were examined; scanning electron microscopy was employed to study ultrastructural elements of anatomical characters. The results revealed the presence of a new species (Jorunna artsdatabankia n. sp.) and a possible case of incipient speciation in J. tomentosa with our COI data indicating the presence of two morphoanatomically indistinct lineages that are separated from each other by distances of 3.2–5.0%. The genetic distance between J. artsdatabankia n. sp. and its sister species J. tomentosa was 9.0–12.3%; the former species is characterized by a plain white to yellow background colour with irregularly placed small brown spots, smooth radular teeth and a longer vas deferens, wider vagina and a longer copulatory spine (up to 600 μm longer) than the latter. A diagnostic comparison of all species of European Jorunna is included, as well as a discussion of the assignment of J. lemchei to the genus Gargamella.   Jorunna artsdatabankia n. sp.

| 2:51p | [Herpetology • 2021] Megophrys acehensis & M. selatanensis • Two New Species of Megophrys Kuhl and Van Hasselt (Anura: Megophryidae) from Sumatra, Indonesia
Abstract We evaluated the taxonomic status of the genus Megophrys in Sumatra using molecular and morphological data. Mitochondrial phylogenetic inference and morphological data revealed two undescribed species, one in southern Sumatra—Megophrys selatanensis sp. nov. and one in northern Sumatra—M. acehensis sp. nov. We also detected a potential cryptic species within M. parallela, but refrain from describing this lineage here due to insufficient data. Genetic variation within Sumatran Megophrys is highly structured and will require additional geographic sampling to understand the interplay between geography and genetics in Sumatran Megophrys. Keywords: Amphibia, Bukit Barisan, molecular phylogeny, taxonomy, Sunda Shelf
Megophrys acehensis sp. nov. Etymology. The specific name acehensis is derived from the province of Aceh in northern Sumatra and the Latin suffix –ensis meaning from that place. Suggested English common name. Aceh Horned Frog Suggested Indonesian name. Katak–tanduk Aceh   Megophrys selatanensis sp. nov. Etymology. The specific name selatanensis is derived from the Indonesian word Selatan (= south), as the new species exhibits a southern distribution within Sumatra and the Latin suffix – ensis meaning from that place.
