| 2:14a | [Paleontology • 2024] Araripesuchus manzanensis • A New Species of Araripesuchus with durophagous dentition increases the ecological disparity among uruguaysuchid crocodyliforms
Abstract Notosuchia is a group of crocodyliforms with mostly terrestrial habits that lived during the Mesozoic and up to the Miocene. Within this group Uruguaysuchidae is so far represented by eight species, six of them clustered in the genus Araripesuchus. Two species of this genus, A. patagonicus and A. buitreraensis, come from different localities in Patagonia (Argentina) from the Candeleros Formation (Cenomanian age). Here we present a third species of Araripesuchus from this formation. The new species comes from the same locality as Araripesuchus buitreraensis, but differs in numerous features including the presence of different molariform teeth. The new species was included in a phylogenetic analysis and, in agreement with previous analyses, Uruguaysuchidae is recovered as monophyletic and placed within Notosuchia as the sister clade of Peirosauridae. Uruguaysuchidae includes all species of Araripesuchus as well as Anatosuchus minor and Uruguaysuchus aznarezi. The new species adds new information to the ecological diversity of the group its bulbous molariforms with a quadrangular occlusal surface bounded by mamelons is interpreted as indicative of a durophagous diet, suggesting the presence of niche partitioning between the two sympatric species A. manzanensis and A. buitreraensis.

| 6:39a | [Entomology • 2023] Argentinomyia aurifacies, A. serendipia, A. tropandeana, etc. • Taxonomic Revision of the Neotropical Genus Argentinomyia Lynch-Arribálzaga, 1891 (Diptera: Syrphidae), with Description of 16 New Species
Abstract The Neotropical flower fly genus Argentinomyia Lynch-Arribálzaga (Diptera: Syrphidae) is revised and rediagnosed. An updated key to the Neotropical genera of Bacchini and Melanostomini is provided. As a result of the ongoing systematic study of the genus, sixteen new species were discovered and described: Argentinomyia aurifacies Montoya & Thompson sp. nov. (Dominican Republic), Argentinomyia belmira Montoya & Wolff sp. nov. (Colombia), Argentinomyia humboldti Montoya & Wolff sp. nov. (Colombia and Ecuador), Argentinomyia ivani Montoya sp. nov. (Colombia), Argentinomyia jalcaensis Thompson & Montoya sp. nov. (Perú), Argentinomyia jamaicensis Montoya sp. nov. (Jamaica), Argentinomyia norrbomi Montoya sp. nov. (Brazil), Argentinomyia occidentalis Montoya & Wolff sp. nov. (Colombia), Argentinomyia plaumanni Thompson & Montoya sp. nov. (Brazil), Argentinomyia sagoti Montoya sp. nov. (Mexico), Argentinomyia serendipia Montoya sp. nov. (Colombia), Argentinomyia spinifemorata Montoya sp. nov. (Colombia), Argentinomyia taina Montoya & Thompson sp. nov. (Dominican Republic), Argentinomyia teresae Montoya sp. nov. (Colombia), Argentinomyia transversalis Montoya sp. nov. (Colombia and Bolivia) and Argentinomyia tropandeana Montoya sp. nov. (Colombia, Ecuador and Perú). Five new synonyms are proposed for four species: Melanostoma melanocerum (Williston, 1891) = Argentinomyia catabomba (Williston, 1891), Braziliana columbiana (Enderlein, 1935) = Argentinomyia fastigata (Fluke, 1945), Braziliana peruviana (Shannon, 1927), Braziliana thiemei (Enderlein, 1935) = Argentinomyia longicornis (Walker, 1836) and Rhysops funerea (Hull, 1949) = Argentinomyia nigrans (Fluke, 1945). Lectotypes are designated for the following names: Melanostoma catabombum Williston, 1891, Melanostoma crenulatum Williston, 1891, Melanostoma longicornis Williston, 1888, Melanostoma melanocerum Williston, 1891 and Pipiza longicornis Walker, 1836. Twenty-six species are redescribed and an updated key proposed for 41 out of the 47 species recognized as valid. Synonyms, descriptions, comparative diagnosis, high-definition color photographs of overall appearance, illustrations of the male genitalia as well as field photographs are provided. The known distribution ranges are mapped and the biogeographical affinity and endemism are discussed. Female genitalia are described for the first time for the genus. Argentinomyia berthae (Lima, 1946) is rediscovered and redescribed, including the designation of a neotype. The taxonomic status of Argentinomyia scitula (Williston, 1888) is considered doubtful and needs further study. Taxonomic notes are provided for Argentinomyia aenea (Willistoni, 1891) and A. huitepecensis Montoya, 2020. The high diversity, the biogeographical affinities, the noteworthy endemism patterns, new country records as well as the morphological variation evidenced in the present revision suggest that the genus is much more diverse than it appears, with many new species that undoubtedly remain to be described from unexplored areas of the Neotropics. Our study provides a thorough morphological assessment as well as the updated biogeographical distribution, which constitute a starting point to answer questions and propose hypotheses about the phylogenetic relationships, historical biogeography, diversification patterns and conservation of Argentinomyia in forthcoming contributions.

| 7:05a | [Entomology • 2022] Taxonomic Revision of Montina (Hemiptera: Heteroptera: Reduviidae) from Colombia with Description of Three New Species; Montina calarca, M. gladiator, M. tikuna
Abstract The Neotropical assassin bug genus Montina Amyot & Serville, 1843 (Reduviidae: Harpactorinae) is revised for Colombia. Montina has not been adequately explored taxonomically, with its last described species published in 1867. It has ten valid species distributed in tropical areas of Central and South America, but none of them have been formally recorded from Colombia. We describe three new species, M. calarca Mejía-Soto & Forero sp. nov., M. gladiator Mejía-Soto & Forero sp. nov., M. tikuna Mejía-Soto & Forero sp. nov., and report seven species as new records for the country: M. confusa (Stål, 1859), M. distincta (Stål, 1859), M. fumosa (Stål, 1867), M. lobata Stål, 1859, M. ruficornis (Fabricius, 1803), M. scutellaris Stål, 1859, and M. testacea (Stål, 1859). Montina calarca sp. nov. is distinguished by the reddish coloration with black head and legs; densely setose pronotum; connexival margin rounded on segments 4, 5, and 6 without protuberances, connexivum black with a narrow red band on margin; and translucent yellow membrane with hyaline cells and darkened veins. Montina gladiator sp. nov. is distinguished by the red coloration, with black legs, scutellum, and abdomen; connexival margin 4–5 lobed, 6 straight, segments 2–4 with acute posterior process on each segment, connexivum dark brown to black with a narrow red band on its margin. Montina tikuna sp. nov. is distinguished by the reddish-brown coloration, with black scutellum and abdomen; connexival margin nearly straight, segments 2–4 with small posterior acute process, 5–6 with obtuse process, connexivum black; ventral laterotergites only with black scattered erect setae. New characters help delimit Montina and differentiate it from Ploeogaster Amyot & Serville, 1843, its most similar genus. For all species we provide a diagnosis, images, documentation of genitalia, and distribution maps. A key to all the species of Montina is provided.

| 9:57a | [Botany • 2020] Tofieldia ulleungensis (Tofieldiaceae) • A New Species, endemic to Ulleungdo Island, Korea
Abstract Tofieldia ulleungensis, a new species of the genus Tofieldia from the Nari Basin on Ulleungdo Island, Korea, is described and illustrated. The new species is similar to T. yoshiiana var. koreana in terms of the plant height and in that it has having a long raceme, whitish tepals, and whitish stigma, but can be readily distinguished from the latter by the presence of 1-2 linear cauline leaves, a slightly bent leaf apex, basal leaves which are twice as wide, a shorter pedicel, a revolute style, and crescent-shaped seeds.

| 10:25a | [Botany • 2024] Corydalis varolaydinii (Papaveraceae, sect. Corydalis ) • A New Species from southwestern Turkey
Corydalis varolaydinii Yıldırım (Papaveraceae) is described as a new species from Köprüalan, Aydın Province, southern Anatolia, Turkey. Diagnostic characters and a full description are provided. Based on morphological features, it belongs to Corydalis sect. Corydalis subsect. Corydalis series Helicosyne. It resembles C. caucasica subsp. caucasica, C. caucasica subsp. abantensis, C. integra and C. paschei, but differs from them in several morphological characteristics, such as its light to whitish to light pinkish corolla, emarginate lower petal, absence of calyx, clear green leaves, mostly undivided leaflets, always entire bracts, shorter pedicel and number of seeds. The new species’ conservation status is Critically Endangered (CR) [B2ab (iii,v)].     Corydalis varolaydinii Yıldırım sp. nov. Tuğkan Özdöl, Kenan Akbaş and Hasan Yıldırım. 2024.

| 3:29p | [Ichthyology • 2024] Schistura sonarengaensis • A New Species of Cave-dwelling Loach (Cypriniformes: Nemacheilidae) from Meghalaya, northeast India
Abstract A new species of nemacheilid loach, Schistura sonarengaensis sp. nov., is described from three cave-dwelling populations (Barak–Surma–Meghna drainage) in the South Garo Hills district of Meghalaya, India. The new species possesses prominent eyes but is easily distinguished from all the congeners of the genus Schistura from Barak–Surma–Meghna and adjacent rivers drainages of northeast Indian (except S. syngkai) in having 13–26 vertically elongated to circular mid-lateral black blotches (brownish in life) overlayered on a grayish-black mid-lateral stripe on a dull white or pale-beige (golden brown in life) body. However, it can be easily distinguished from S. syngkai in having a complete (vs. incomplete) lateral line with more 72–89 (vs. 19–42) lateral-line pored scales, greater pre-dorsal length (48.5–53.1 vs. 41.9–44.1 %SL), a wider body at dorsal-fin origin (11.3–16.7 vs. 9.4–10.3 %SL), greater dorsal (18.1–21.1 vs. 15.1–17.0 %SL) and lateral (20.9–24.1 vs. 17.4–18.9 %SL) head length, a wider head (14.5–18.5 vs. 11.6–13.3 %SL), and moderately forked (vs. emarginated) caudal fin. Further, molecular analysis confirms the distinctiveness of S. sonarengaensis sp. nov. from its congeners found in northeast India by significant divergences with uncorrected genetic distance ranging from 3.7% to 17.3% in the mitochondrial cytochrome c oxidase subunit I (COI) gene dataset. The phylogenetic position of the new species with its sister species was evaluated using maximum likelihood and Bayesian analysis. The species delimitation approaches assemble species by automatic partitioning (ASAP) and Poisson tree processes (PTP) utilized for testing species assignments consistently identified our test group as a distinct species from its sister species. Although the new species lacks typical morphological adaptations usually associated with a subterranean life, such as complete absence (or vestigial presence) of eyes and pigmentation, it exhibits a reduction of pigmentation when compared to the epigean congeners.
