| 1:34a | [Entomology • 2024] Euclimacia radioquaesentis • A New Species of the Mantidfly Genus Euclimacia (Neuroptera: Mantispidae) from Vietnam
Abstract A new species of the family Mantispidae (Neuroptera) from Vietnam is described. Euclimacia radioquaesentis sp. nov. shows a unique colour pattern, which is distinctive within the genus. The colouration and morphology of both sexes of the new species are described in detail and illustrated. The naming of the new species is linked to a popular citizen-science event in choosing the name for this species (and three other species from different undescribed species by taxonomists of the Museum für Naturkunde Berlin). Key Words: Adaption, lacewings, mimicry, new species, parasitoid, polymorphism, sexual dimorphism, Southeast Asia, wasp mimic
Class Insecta Linnaeus, 1758 Order Neuroptera Linnaeus, 1758 Family Mantispidae Leach, 1815 Subfamily Mantispinae Leach, 1815 Genus Euclimacia Enderlein, 1910 Type species: Euclimacia partita Enderlein, 1910: 366, by original designation. Euclimacia radioquaesentis sp. nov. Diagnosis: The combination of colour characters in the new species is unique within Euclimacia. The contrast between the head and prothorax and the rest of the thorax and abdomen is striking. The prothorax and head have a distinct yellow colour, the remaining thorax is almost uniformly black. The abdomen of the male is also almost completely black with only a few brown markings. The female has a brownish abdomen with a black base. The wing colour is also unique in combination with the body colouration. The wings of E. radioquaesentis have the prominent feature of differently-coloured pterostigmata in fore and hind wing. Whereas the fore-wing pterostigma is yellow, the hind-wing pterostigma is brown. There are currently six species in Euclimacia with this diagnostic character, but these species differ distinctly in body colouration. Whereas in E. radioquaesentis sp. nov., the head and the prothorax are markedly yellow, in the other six species both parts are either ferruginous (E. rhombica Navás, 1914), reddish-brown (E. morosa (Gerstäcker, 1893); E. zonalis Navás, 1914; E. regina Esben-Petersen, 1917; E. rufocincta Handschin, 1961) or completely black (E. gerstaeckeri Banks, 1920). Etymology: The species epithet is made up of two words ‘radio’ and ‘quaesentis’. The latter derives from Latin and means ‘searched for’. The name was chosen as part of a radio show. Citizens were invited to submit name suggestions. The most suitable was radioquaesentis – searched for on the radio. Sarah Ehlers, Hongyu Li, Lukas Kirschey and Michael Ohl. 2024.

| 3:11a | [Ichthyology • 2024] Urkumayu gen. nov. & ‘Hoplisoma’ osvaldoi • Integrative Phylogeny of Corydoradinae (Siluriformes: Callichthyidae) with an emphasis on Northwestern La Plata Species, including Descriptions of A New Genus and Species
Highlights • New phylogenetic hypothesis for diverse Neotropical fish genus Corydoras • Integration of molecular and morphological data from 153 species • Discovery of a new clade, including Andean and upper Paraná basin species • Identification of emerging endemicity hotspots in NW La Plata basin • Description of a new species and assessment of conservation status Abstract The knowledge about the diversity and phylogeny of South American callichthyid armored catfishes of the subfamily Corydoradinae is still growing, after important recent contributions, and many species have uncertain relationships. In this study, we present the first combined phylogenetic hypothesis for the genus based on five genes, 83 morphological characters, and 153 species, providing synapomorphies for some of the main genera of Corydoradinae, as recently defined. The inclusion of species not previously analyzed in a phylogenetic context challenged the monophyly of Hoplisoma and required the definition of a new genus for endemic species from the Andean portion of the northwestern La Plata basin (ANWLP): Hoplisoma gladysae, H. micracanthum, and H. petracinii. We found Hoplisoma non monophyletic with Hoplisoma sensu stricto not sister to a clade of species herein named the ‘Hoplisoma’ paleatum clade. In this clade we recovered a new species of Hoplisoma, which is endemic to the upper Bermejo basin, as sister to ‘Hoplisoma’ paleatum from the lower La Plata basin. The new species is distinguished from all congeners by a unique coloration similar to that of the syntopic H. micracanthum, suggesting a putative case of Müllerian co-mimicry. Key words: Müllerian co-mimicry, coloration, endemic species, Upper Bermejo, threatened species
Urkumayu, new genus Alonso, Terán, Aguilera, Montes, Serra Alanís, Calviño, Vera-Alcaraz, Cardoso, Koerber, Mirande Type species: Corydoras gladysae Calviño & Alonso 2010 Diagnosis: Urkumayu is distinguished from the remaining genera of Corydoradinae by the following unique combination of characters: supraoccipital and nuchal plate not in contact, posterior expansion of pharyngobranchial triangular, and ossified portion of pectoral spine strongly reduced. Included species: Urkumayu gladysae (Calviño & Alonso 2010) n. comb., Urkumayu micracanthus (Regan 1912) n. comb., Urkumayu petracinii (Calviño & Alonso 2010) n. comb. Etymology: Urkumayu, masculine gender, from the Quechua language, compound of urku meaning mountain and mayu for river, referring to the habitat where most species of this genus are found. Distribution: It has a disjunct distribution in northwestern Andean La Plata Basin in Argentina.
Hoplisoma osvaldoi, new species Alonso, Terán, Aguilera, Montes, Serra Alanís, Calviño, Vera-Alcaraz, Cardoso, Koerber, Mirande Etymology: The specific epithet honors Jorge Osvaldo Fernández Santos, an esteemed aquarist and fish collector who made significant contributions to the knowledge of Argentinean fish by collecting and generously donating numerous specimens to scientific collections and collaborating with ichthyologists. He had been an avid promoter of the fish keeping hobby, particularly with respect to native species. As a result, this species is named in recognition of Osvaldo’s contributions to the study and knowledge of Argentina’s fishes.

Abstract Echinoagave nievesiorum (Agavaceae, Asparagales), a new species endemic to the Sierra Wixárika (Huichola), part of the Sierra Madre Occidental, Jalisco, Mexico, is described. This species shares morphological characteristics with Echinoagave rzedowskiana but it differs from the latter by having narrower and striate leaves; leaf sheaths shorter, triangular and wider at the base; narrower ovary width; shorter tube length; tepal lobes at anthesis converging and tightening the filaments; larger filament length to flower length ratio; fruiting spikes thicker and denser with the peduncle covered by the capsules and the bracts usually deciduous; capsules broadly ellipsoid with dorsally blackish valves. A distribution map with biogeographic provinces is provided to place the species in an ecological and evolutionary context. Allopatric speciation, endemic, Group Striatae, Sierra Huichola, subgen. Littaea, Monocots
Echinoagave nievesiorum A. Vázquez, A.T. Nuño, Cházaro, Padilla-Lepe & García-Mor. sp. nov. Diagnosis:—Echinoagave nievesiorum shares with E. rzedowskiana a similar rosette size and cespitose habit, rigid leaves, length of
flowers, ovaries, tepal lobes, and size of capsules; however, it differs from the latter by having mature leaves bluish-white to whitish
(vs. pale-green to green), narrower at the widest part (12.0–12.5 mm vs. 13.0–14.0 mm), and narrower at the middle of the leaves
(6.0–6.5 mm vs. 7.0–10.0 mm); leaf sheaths shorter (9.0–11.0 mm vs. 28.0–34.0 mm), triangular and wider at the base (vs. rectangular
and wider above the base); inflorescences usually straight and erect, sometimes vertically-curved or geniculate, rarely dropping (vs.
usually horizontally-curved, often dropping and sinuous) narrower ovary width (4.5–5.1 mm vs. 5.7–7.5 mm); shorter tube length
(5.5–6.4 mm vs. 7.0–10.0 mm); tepal lobes at anthesis converging and tightening the filaments (vs. diverging and not tightening the
filaments); larger filament length to flower length ratio (2.0–2.3 vs. 1.8–1.9); fruiting spike narrowly pyramydal thicker (3.5–4.5
cm vs. 2.4–2.5 cm) and denser with the peduncle covered by the capsules and the bracts usually deciduous (vs. cylindroid, slim and
lax, with the peduncle conspicuous and the bracts usually persistent); mature capsules broadly ellipsoid with dorsally blackish and
opaque valves (vs. broadly ovoid, slightly depressed, with dorsally light brown and shiny valves) (Table 1). Etymology:—The specific epithet honors the family members of Prof. Gregorio Nieves Hernández, who have contributed notably for over a decade to the knowledge of vascular flora and ethnobotany of the Sierra Wixarika.

| 10:51a | [Botany • 2024] Phelipanche cingularum (Orobanchaceae) • A New Species from southern France
Abstract A new species of Phelipanche has been discovered in various steep places in southern France at meso- and supra-mediterranean levels. It is always parasitic on Brassicaceae, almost exclusively on Hesperis laciniata, a plant that had never been reported as host for any Orobanchaceae previously. The new species, named Phelipanche cingularum for its rocky ledge (cingula) habitat, is described and illustrated. Diagnostic characters against up to 16 presumably related species are given. We also present the results of molecular analyses well-supporting its independence. The distribution and the unusual ecology of the plant are considered and illustrated, and its conservation status is evaluated.

 Phelipanche cingularum Croze, Carlón, J.-M.Tison, Michaud, J.Molina & Moreno Mor., sp. nov. Etymology:—the specific epithet is from a feminised late Latin form (genitive of cingula) derived of the classical Latin cingulum (belt), having given place to several words applied in southern France to grassy fringes surrounding limestone cliffs along its base or in ledges. It refers to the peculiar ecology of the plant grows on small flat rocky areas,or « vires » in French. French name:—Phélipanche des vires.
