Twenty new species of Scaphidiinae (Coleoptera: Staphylinidae) from Minas Gerais, Southeast Brazil
No full textScaphidiinae (shining fungus beetles) is a subfamily of Staphylinidae generally associated with fungi and slime moulds. They are distributed worldwide, but the Brazilian fauna is poorly known. In this manuscript, twenty new species assigned to five genera are described: Cyparium fugitivum sp. nov., Alexidia convivalis sp. nov., A. solitaria sp. nov., Baeocera ardua sp. nov., B. bottine sp. nov., B. colibri sp. nov., B. facilis sp. nov., B. inusitata sp. nov., B. pulga sp. nov., Scaphisoma hilarum sp. nov., S. infinitum sp. nov., S. mutabile sp. nov., S. peculiare sp. nov., Toxidium brigadeirense sp. nov., T. distortum sp. nov., T. fleche sp. nov., T. inusitatum sp. nov., T. scalenum sp. nov., T. speratum sp. nov. and T. ultimum sp. nov. The specimens were collected in remnants of Atlantic Forest, in Minas Gerais, Southeast Brazil, directly from the host (fungi and/or slime moulds). Descriptions include host associations, illustrations of the external and internal morphology of adult males and females, whenever it is possible. Also, an illustrated key to the Brazilian genera and their respective diagnoses is provided.</p

Une espèce nouvelle, <i>Lochriea monocarinata</i> n. sp., et sa position dans le morphoespace du genre <i>Lochriea</i> Scott, 1942 (Conodonta, Mississippien)
No full textLa nouvelle espèce de conodontes du Mississippian Lochriea monocarinata n. sp. élargit la diversité des représentants ornementés du genre Lochriea Scott, 1942. Lochriea monocarinata n. sp. diffère de ses proches parents par la présence d’une crête nodosée uniquement sur la partie interne (caudale) de la coupe basale asymétrique. L’aire de répartition de la nouvelle espèce, limitée par la zone à Lochriea ziegleri, permet de l’utiliser comme marqueur biostratigraphique auxiliaire du Serpukhovien inférieur.The new species of the Mississippian conodonts Lochriea monocarinata n. sp. extends the diversity of the ornamented representatives of the genus Lochriea Scott, 1942. Lochriea monocarinata n. sp. differs from its close relatives by the presence of a nodose ridge only on the inner (caudal) part of the asymmetrical basal cup. The range of the new species, restricted to the Lochriea ziegleri Zone, allows it to be used as an auxiliary biostratigraphic marker of the lower Serpukhovian.</p
Premier rapport dans le registre fossile d’une dent de requin enchâssée dans un os de Pinnipède
No full textIl existe aujourd’hui de nombreux signalements fossiles portant des marques de morsures de requins préservées sur des matériaux biogènes, notamment des coprolithes, des ammonoïdes, des osselets d’étoiles de mer, un échinoïde, des os et du cartilage calcifié. Ces fossiles exceptionnels témoignent d’un comportement explorateur, d’une prédation active et/ou d’une activité de charognage. Cependant, seul un petit sous-ensemble rapporte la présence de dents de requins incrustées dans de l’os ou du cartilage fossilisé. Bien que quelques os de phoques marqués par des dents de requins soient connus dans les archives fossiles, aucune preuve directe de prédation ou de charognage sous la forme d’une dent de requin incrustée dans un os de phoque fossile n’a encore été documentée. Nous décrivons ici la première dent de requin incrustée dans un os de phoque (Phocidae Gray, 1821), un calcanéum (CMM-V-6964), qui a été prélevé en surface dans la mine de Mosaic South Fort Meade, dans le comté de Hardee, à Fort Meade, en Floride, aux États-Unis. La dent partielle a été identifiée comme provenant d’un grand requin blanc du Pliocène précoce, Carcharodon carcharias (Linnaeus, 1758). Cette découverte représente également la première dent de C. carcharias jamais trouvée intégrée dans un os fossile. La dent incrustée pourrait être le résultat d’une prédation active ou d’une fouille. Les requins macroprédateurs existants, Carcharodon carcharias (Linnaeus, 1758) (grand requin blanc), Notorynchus cepedianus (Péron, 1807) (requin septgill), Somniosus microcephalus (Bloch & Schneider, 1801) (requin du Groenland) et Somniosus antarcticus Whitley, 1939 (requin dormeur), sont connus pour s’attaquer activement aux phoques (Pinnipedia Illiger, 1811). Si cette association fossile particulière résulte d’une prédation active, le phoque n’a pas survécu à la rencontre car il n’y a aucun signe de guérison dans la zone entourant la dent de requin incrustée.There are now many examples in the fossil record of shark bite marks preserved on biogenic materials including coprolites, ammonoids, sea star ossicles, an echinoid, and bone and calcified cartilage. These exceptional fossils document evidence of exploratory behavior, active predation, and/or scavenging. However, only a small subset report on the presence of shark teeth embedded in fossilized bone or cartilage. Although a few shark tooth-marked seal bones are known from the fossil record, no direct evidence of predation or scavenging in the form of a shark tooth embedded in a fossil seal bone has yet been documented. Herein, we describe the first shark tooth embedded in a seal (Phocidae Gray, 1821) bone, a calcaneum (CMM-V-6964), that was surface collected in Mosaic’s South Fort Meade Mine, Hardee County, Fort Meade, Florida, United States. The isolated bone originated from within the Bone Valley Member of the Peace River Formation (Hawthorn Group). The partial tooth is identified as having come from an Early Pliocene great white shark, Carcharodon carcharias (Linnaeus, 1758). This discovery also represents the first C. carcharias tooth ever found embedded in a fossil bone. The embedded tooth may have come about as a result of active predation or scavenging. The extant macropredatory sharks, Carcharodon carcharias (great white shark), Notorynchus cepedianus (Péron, 1807) (sevengill shark), Somniosus microcephalus (Bloch & Schneider, 1801) (the Greenland shark), and Somniosus antarcticus Whitley, 1939 (sleeper shark), are known to actively prey upon seals (Pinnipedia Illiger, 1811). If this peculiar fossil association resulted from active predation, the seal did not survive the encounter because there is no evidence of healing in the area around the embedded shark tooth.</p
Updating the morphological phylogenetics of Nopinae (Araneae: Caponiidae): novel terminals and characters, with two new species
No full textA re-analysis of the morphological phylogeny of the Nopinae is made, based on an update in the description of Aamunops Galán-Sánchez & Álvarez-Padilla, 2022 and the addition of the recently described genera Nopsma Sánchez-Ruiz, Brescovit & Bonaldo, 2020 and Roddemberryus Sánchez-Ruiz & Bonaldo, 2023. Two new species, Aamunops hoof sp. nov. (male) and Aamunops yiselae sp. nov. (male and female), are also described, which allows a better understanding of the genus morphology and resulted in an emended diagnosis. The description of Aamunops has been updated to include several characteristics of the ultrastructural morphology, legs, chelicerae, palps and female genitalia. The inclusion of these new characters of Aamunops along with those of Nopsma and Roddemberryus in the previous data matrix resulted in a new, completely different hypothesis of the relationships of the nopine genera: Nopsma is part of a group formed by Cubanops and Nyetnops, while Aamunops and Roddemberryus are grouped with representatives of Tarsonops. The four-eyed Nopsides ceralbonus Chamberlin, 1924 was recovered as the most basal species of Nopinae. The relationships among genera of Nopinae and the phylogenetic position of three species, whose taxonomic position is doubtful (Cubanops luquillo Sánchez-Ruiz, Brescovit & Alayón, 2015, Orthonops confuso Galán-Sánchez & Álvarez-Padilla, 2022 and Tarsonops irataylori Bond & Taylor, 2013), is also discussed.</p
A new genus of Cicadellini (Hemiptera: Cicadellidae) from the Oaxacan Cloud Forest, with taxonomic notes on allied red-striped genera
No full textCicadellinae is a relatively large subfamily of leafhoppers (Hemiptera: Cicadellidae) with a cosmopolitan distribution with most genera known to occur in the Neotropics. Mexico houses nearly 16% of the total genera and most are endemic, inhabiting threatened native forests. Here, a new unusual Mexican genus, Christopherus gen. nov., is described to accommodate a new species of Cicadellini, C. mictlantecuhtli sp. nov., collected in the endangered Cloud Forest of Sierra Juárez, Oaxaca State of Mexico, based on dry-pinned museum specimen data. The new taxa can be separated from other Neotropical Cicadellini genera easily using male genitalia features: (i) pygofer without processes, (ii) segment 10th without processes, (iii) paraphysis absent, and (iv) edeagus with single basal atrial process elongate and asymmetrical. The monotypic genus Gillonella with its type species, G. ampulla Nielson & Godoy, 1995, are redescribed. A detailed extensive morphological description and discussion to distinguish the new genus from allied red-striped Neotropical genera in Mexico, Central America, and South America are given. Distributional data for new taxa within Mexican forests is also provided.</p
A revision of the genus <i>Armillipora</i> Quate (Diptera: Psychodidae) with the descriptions of two new species
No full textThe genus Armillipora Quate is recorded for the first time in Ecuador, with a new geographical record for Armillipora selvica Quate, 1996 and the descriptions of two new species, namely Armillipora muyu sp. nov. and Armillipora imitata sp. nov., doubling the total number of species in the genus. In addition, we make available the first DNA barcodes for the genus, providing a sequence of the 5´-end of the cytochrome c oxidase subunit I (COI) gene for A. imitata, A. muyu, and, A. selvica. Moreover, we describe the second known female of the genus and we provide a taxonomical key for the known males of the world. Finally, we build Species Distribution Models and discuss the potential distribution of the genus in the Neotropical region.The genus Armillipora Quate is recorded for the first time in Ecuador, with a new geographical record for Armillipora selvica Quate, 1996 and the descriptions of two new species, namely Armillipora muyu sp. nov. and Armillipora imitata sp. nov., doubling the total number of species in the genus.

Différentiation géographique chez le crabe d’eau douce <i>Potamon persicum</i> Pretzmann, 1962 (Decapoda, Potamidae) dans les monts Zagros ; données de la morphométrie
No full textLe crabe d’eau douce Potamon persicum Pretzmann, 1962 en Iran est présent le long des monts Alborz occidentaux, son aire de répartition s’étendant vers le sud-est à l’ensemble des monts Zagros. Nous nous attendions à une forte différentiation géographique au sein de Potamon persicum entre les principaux systèmes de drainage de la région (bassins Khalij Fars-Oman, Markazi et Urmia). Pour tester cette hypothèse, nous avons effectué des analyses classiques de morphométrie et de morphométrie géométrique. La comparaison des mâles et des femelles entre les populations de trois principaux systèmes de drainage a montré des différences significatives pour onze caractères. Nous avons également détecté des différences significatives selon le sexe entre les trois principaux systèmes de drainage. Les résultats ont été corroborés par une analyse de morphométrie géométrique de la forme de la carapace, qui varie selon le sexe et entre les populations des trois principaux systèmes de drainage. D’après ces deux analyses, les populations des bassins de Khalij Fars-Oman et de Markazi sont similaires. En outre, une différentiation plus élevée a été observée entre les populations des bassins de Markazi et d’Ourmia. Nous émettons l’hypothèse que la différenciation géographique de P. persicum est le résultat à la fois de l’isolement par la topographie et du climat pendant les périodes glaciaires du Pléistocène.The freshwater crab Potamon persicum Pretzmann, 1962 in Iran is distributed along the western Alborz Mountains, its range extending southeast through the whole Zagros Mountains. We expected a high geographic differentiation within Potamon persicum between the main drainage systems in the region (Khalij Fars-Oman, Markazi and Urmia basins). To test this hypothesis, we conducted conventional morphometric and geometric-morphometric analyses. Comparison of males and females between populations of three main drainage systems showed significant differences of eleven traits. We also detected significant sex-specific differences among the three main drainage systems. The results are supported by geometric-morphometric analysis of the carapace shape, as carapace shape varies between sex and populations of three main drainage systems. Based on both analyses, populations of Khalij Fars-Oman and Markazi basins are similar to each other. Furthermore, a higher differentiation was seen between populations from Markazi and Urmia basins. We hypothesize that the P. persicum geographic differentiation is a result of both isolation by topography and climate during the Pleistocene glacial periods.</p
