Item Revision of Acroleptus Bourgeois, 1886 and descriptions of New Acroleptina taxa (Coleoptera, Lycidae, Calopterini)(2019-12) Ferreira, Vinicius S.The Neotropical lycid genus Acroleptus Bourgeois, 1886 is revised and illustrations of diagnostic characters, geographic distribution maps and an identification key to the species are presented. Acroleptus chevrolati Bourgeois, 1886 is redescribed and a lectotype and a paralectotype are designated; two new species are described for the genus: Acroleptus alvarengai new species and Acroleptus limai new species. Two Aporrhipis Pascoe, 1887 species are described: Aporrhipis obrieni new species and Aporrhipis milleri new species and a key and geographic distribution map to the species of the genus are provided. Acroleptus costae Ferreira, 2015 is moved to the genus Paracroleptus new genus, a new genus erected to accommodate Paracroleptus costae (Ferreira, 2015) new combination.Item The description of Prototrichalus gen. nov. and three new species from Burmese amber supports a mid-Cretaceous origin of the Metriorrhynchini (Coleoptera, Lycidae)(2020-07) Molino-Olmedo, Francisco; Ferreira, Vinicius S.; Branham, Marc A.; Ivie, Michael A.Despite the many substantial advances and progress in understanding the internal evolutionary relations of several Lycidae groups, the divergence time estimation of the family within Elateroidea remains subject of debate, with estimates to as early as the mid-Jurassic. Herein we describe Prototrichalus gen. nov., and three new species: Prototrichalus sepronai sp. nov., Prototrichalus meiyingae sp. nov. and Prototrichalus milleri sp. nov., from Burmese amber of the Cenomanian Age (mid-Cretaceous), supporting an age for the tribe of at least 100 Ma. The new taxa belong to the tribe Metriorrhynchini and are the oldest recognizable beetles from this lineage, indeed, among the oldest known representatives of the Lycidae. The discovery and description of Prototrichalus and its three species provides direct evidence of the group's as a recognizable group in the mid-Cretaceous, much earlier than the recent predictions in the Late Cretaceous.Item A revision of Lycinella Gorham, 1884 with the description of six new species (Coleoptera, Lycidae, Calopterini)(2018-01) Ferreira, Vinicius S.; Ivie, Michael A.The Neotropical genus Lycinella Gorham, 1884 is revised. Lycinellaopaca Gorham, 1884 and Lycinellaparvula Gorham, 1884 are redescribed and illustrated. Six new species are described for the genus: Lycinellaadamantis sp. n., L.hansoni sp. n., L.milleri sp. n., L.cidaoi sp. n., L.marshalli sp. n. and L.pugliesae sp. n.. Lycinellahumeralis Pic, 1933 is moved to Ceratoprionhumerale (Pic, 1933), comb. n. A key to the species of Lycinella, illustrations and a distribution map is provided.Item A new suspected paedomorphic genus of net-winged beetles from the Atlantic Rainforest (Coleoptera, Elateroidea, Lycidae)(2020-02) Ferreira, Vinicius S.; Lima Silveira, Luiz FelipeLycidae are among the better studied groups in the superfamily Elateroidea, however despite the progress in the taxonomic understanding of the Neotropical fauna, much still remains unknown and undescribed in the region. The description of the new genus Xenolycus gen. nov., from Serra dos Órgãos, a subrange of the Serra do Mar mountain range, in the Atlantic Rainforest in Rio de Janeiro State, Brazil, contributes to the knowledge of the Neotropical Lycidae fauna. The new genus can be distinguished from all other known Calopterini and Neotropical Lycidae by the combination of a pronotum with a wide, deep and strongly visible longitudinal cell in the disc area, the filiform antennae, the dehiscent elytra with reticulation strongly reduced and bearing only two weakly developed elytral costae and the mouthparts partially reduced, with rudimentary, barely visible mandibles. The type species, Xenolycus costae sp. nov., is illustrated and diagnostic characters and a discussion on the tribal placement of the new genus are provided.Item Redescription of Aporrhipis Pascoe, 1887 (Coleoptera: Lycidae), with a Discussion of its Tribal Placement(2018-06) Ferreira, Vinicius S.; Barclay, Maxwell V. L.; Ivie, Michael A.Aporrhipis flexilisPascoe, 1887 is the sole species of a monospecific genus of beetles from Brazil, originally described in the family Ripiphoridae. Despite the fact that this genus was moved to Lycidae, its correct tribal placement remains uncertain. In this study, A. flexilis is redescribed, its tribal placement is discussed, and it is tentatively placed within the Calopterini, Acroleptina. The problems of distinguishing the Acroleptina from the Leptolycini are highlighted by this case, and a plea is made for additional specimens to help resolve this conundrum.Item First Record of Peripatus juanensis Bouvier, 1900 (Onychophora, Peripatidae) Found in Cecropia (Rosales, Urticaceae) Fallen Trunks in Puerto Rico(2018-10) Ferreira, Vinicius S.; Spiessberger, Erich L.During a fieldwork expedition to collect beetles of the families Lycidae and Tenebrionidae at the El Verde Field Station in the El Yunque rainforest, we had a fateful encounter with two specimens of Peripatus juanensis Bouvier, 1900. Peripatus juanensis is an endemic species and the only velvet-worm (Onychophora) occurring in Puerto Rico. The species is currently classified in the family Peripatidae (Peck, 1975; Oliveira et al., 2012). Despite the fact that this is the only species of Onychophora from Puerto Rico, little is known about its biology and life cycle.Item A Review of the Nearctic Genus Lucaina Dugès, 1879 (Coleoptera: Lycidae: Lycinae: Calochromini), with Descriptions of Two New Species(2018-09) Ferreira, Vinicius S.; Ivie, Michael A.A review of Lucaina Dugès, 1879 with illustrations of diagnostic characters, distribution maps, and an identification key to the species is presented. Lucaina schini Dugès, 1879, Lucaina discoidalisHorn, 1885, and Lucaina marginataGorham, 1884 are redescribed, and their status as valid species is confirmed. Macrolygistopterus bajacalifornicus (Zaragoza, 2003) is transferred to Lucaina bajacalifornica (Zaragoza, 2003), new combination. Lucaina greeni Ferreira and Ivie, new species and Lucaina milleri Ferreira and Ivie, new species are described. Lectotypes and paralectotypes are designated for L. marginataGorham, 1884, L. schini Dugès, 1879, and L. discoidalisHorn, 1885.Item Redescription of Cephalolycus major Pic, 1926 (Coleoptera: Elateroidea: Lycidae) and a Discussion on Its Taxonomic Position(2016-09) Ferreira, Vinicius S.; Ivie, Michael A.In her revisionary work on the definition of the Calopterini, Bocákova (2003, 2005) was unable to see the type and sole known specimen of the Colombian species Cephalolycus major Pic, 1926, being forced to leave the monotypic Cephalolycus Pic, 1926 incertae sedis due to the lack of sufficient information in the original description. During the process of returning long-outstanding loans on behalf of a retired colleague as part of a donation of a large collection of cantharoids, we discovered a syntype of C. major, the type species (by monotypy) of Cephalolycus, from the Pic Collection of the Muséum National d'Histoire Naturelle, Paris (MNHN). As we return this loaned specimen, we take this opportunity to redescribe it.Item The First Fossil Species of the Extant Genus Cessator Kazantsev (Coleoptera: Lycidae): A New Leptolycini from Dominican Amber(2017-03) Ferreira, Vinicius S.; Ivie, Michael A.Cessator brodzinskyi Ferreira and Ivie, new species, is the third lycid species known from Dominican amber. The new species is described, diagnosed, illustrated, and compared with other fossil and extant species. Leptolycus parda Zaya, 1988 is moved to Cessator parda (Zayas), new combination.Item A new species of Falsocaenia Pic, 1922 from Amazonian Rainforest (Coleoptera: Lycidae) with an updated key to the species(2016-04) Ferreira, Vinicius S.While searching for Calochromini (Coleoptera: Lycidae) specimens in entomological collections and identifying other Lycidae, a new species of Falsocaenia Pic, 1922 was found in the collection of Instituto Nacional de Pesquisas da Amazônia (INPA). This genus is one of the smallest in the tribe Calopterini with 13 known species, two of which were recently described by Bocákova et al. (2012) in their revision of the genus, and can be found in Central and South America.
