In this paper are presented notes on the primary types of some species of the oil-collecting bees of the genus Centris described by the European naturalists and entomologists Amédée Louis Michel Lepeletier de Saint-Fargeau, Anders Christian Jensen-Haarup, Arthur Louis Marie Joseph Vachal, Charles Émile Blanchard, Embrik Strand, Félix Édouard Guérin-Méneville, Guillaume-Antoine Olivier, Jean Guillaume Audinet-Serville, Jean Pérez, Johann Christoph Friedrich Klug, Johann Ludwig Christ, John Obadiah Westwood, Josef Anton Maximilian Perty, Jules Dominique, Karl Hermann Konrad Burmeister, Karl Wilhelm von Dalla Torre, Massimiliano Spinola, Peter Cameron, and Wilhelm Ferdinand Erichson. Information on the type status, type locality and depository are provided. In order to stabilize some names, lectotype designations were made for Centris rhodophthalma, C. sponsa var. asuncionis, C. transversa, Hemisia byssina and Ptilotopus americanus. Centris sponsa var. asuncionis is withdrawn from the synonymy of C. sponsa, revalidated and raised to species level. Centris byssina is proposed as nomen oblitum and as a new junior synonym of C. trigonoides, nomen protectum.
Male cerci variability was used as the main source of information to separate taxonomic units in the genus Pseudochelidura. Based on these data it was considered that three species of Pseudochelidura coexisted in the Pyrenees: P. sinuata, P. minor and P. montuosa. However, our phylogeographic and phylogenetic analyses based on molecular data (mitochondrial cytb and nuclear ITS2) do not support those conclusions. Combining these analyses with morphological studies we concluded that: 1) the Pyrenees are inhabited by a single evolutionary unit: P. sinuata (Germar, 1825) (= P. minor Steinmann, 1979 syn. nov., = P. montuosa Steinmann, 1981 syn. nov.). 2) Cantabrian and Pyrenean populations are reciprocally monophyletic and morphologically diagnosable representing two independent evolutionary units: Pseudochelidura cantabrica Cuesta-Segura, Jurado-Angulo & García-París sp. nov. and P. sinuata. And, 3) their conservation status needs to be evaluated in the light of current taxonomic changes. We have shown that the use of male cerci for species identification is problematic. Patterns of variation possibly affected by sexual selection (e.g., intrapopulational variability) appear to be very difficult to separate from variation driven by natural selection or genetic drift (i.e., character divergence in geographical isolation). The large sequence divergence observed between Pyrenean and Cantabrian populations of Pseudochelidura suggest a lasting genetic and geographic isolation between them, rendering difficult to ascertain their phylogenetic relationships.
The ant genus Vollenhovia Mayr, 1865 (Myrmicinae, Crematogastrini) mostly occurs in the Australasian and Oriental regions. We revised its diversity in India and Sri Lanka based on qualitative and quantitative morphology, recognizing eleven taxa, including a new species which is described herewith: V. escherichi Forel, 1911, V. gastropunctata Bharti & Kumar, 2013, V. karimalaensis Dhadwal et al., 2023, V. keralensis Kripakaran & Sadasivan, 2022, V. mawrapensis Dhadwal et al., 2023, V. oblonga laevithorax Emery, 1889, V. penetrans (Smith, 1857), V. pfeifferi Bharti et al., 2023, V. taylori Rilta et al., 2023, V. terayamai Rilta et al., 2023, and V. yasmeenae sp. nov. The subspecies status of V. oblonga laevithorax and its relationship with V. penetrans, whose type series does not contain workers, still requires to be assessed in the context of a broader revision including the whole Oriental region. The known distribution of the genus in the Indian subcontinent appears to be fragmentary, still requiring extensive sampling efforts. Four species are from the Western Ghats biodiversity hotspot in the southern Indian state of Kerala, one is endemic to the biogeographically related Sri Lanka, three are known from Eastern India near the border with Bangladesh, two are reported from the Andaman and Nicobar Islands, and one is restricted to the Himachal Pradesh in northern India. A comprehensive key of the known Vollenhovia species from India and Sri Lanka is provided.
This review covers Parageron Paramonov s. lat., including 36 species. Three new genera are proposed: Ectopusia gen. nov., Protypusia gen. nov. and Parusia gen. nov.; Parageron s. str. more narrowly defined. Eleven new species are described: Parageron longilingua sp. nov., Protypusia argentata gen. et sp. nov., Pro. separata Gibbs & Theodor gen. et sp. nov., Pro. flavipalpis gen. et sp. nov., Pro. kerkini gen. et sp. nov., Pro. strymonas gen. et sp. nov., Parusia almeria gen. et sp. nov., Pru. benoisti gen. et sp. nov., Pru. cyrenaica gen. et sp. nov., Pru. faesae gen. et sp. nov. and Pru. propinqua gen. et sp. nov. Two species raised from synonymy Par. orientalis Paramonov stat. rev. and Pru. taeniolata (Costa) stat. rev. Two species synonymised Pro. major Macquart syn. nov. and Usia arida Báez syn. nov. Eight species removed from Usiini to Apolysini, Apolysis bicolor (Efflatoun) comb. nov., A. elbae (Efflatoun) comb. nov., A. flavipes (Efflatoun) comb. nov., A. marginata (Brunetti) comb. nov., A. minuscula (Efflatoun) comb. nov., A. parvula (Efflatoun) comb. nov., A. turkmenica (Paramonov) comb. nov. and A. volkovitshi (Zaitzev) comb. nov. Apolysis melanderi Gibbs nom. nov. replaces A. bicolor (Melander) (was in Oligodranes) and A. hessei Gibbs nom. nov. replaces A. minuscula Hesse. Two neotypes and nine lectotypes are designated.
The Neotropical eucnemid genus, Dyscolotaxia Horn, is revised following the examination of specimens from five collections, examination of the published original description of Plesiofornax tetratoma Chassain, and from images provided by Fernanda Salazar-Buenaño (QCAZI). Dyscolotaxia championi Horn is redescribed with included descriptions of the male genitalia and a female specimen. Three new species of false click beetles (Coleoptera: Eucnemidae) are described from the Neotropical region. These new species are: Dyscolotaxia chiriquiensis (Panama), Dyscolotaxia hispaniolensis (Dominican Republic) and Dyscolotaxia picea (Ecuador). Amazotaxia new genus is described from South America for Plesiofornax tetratoma Chassain, creating Amazotaxia tetratoma (Chassain) new combination. Morphology of both Dyscolotaxia and Amazotaxia in relation to Pleisofornax Cocquerel are reviewed along with biogeographical hypotheses for these groups. An identification key is provided for species of Dyscolotaxia in the Neotropical region. Images for all species of Dyscolotaxia and Amazotaxia are provided.
