The genera in the second catalogue (1833–1836) of Dejean’s Coleoptera collection

Abstract

All genus-group names listed in the second edition of the catalogue (1833-1836) of Dejean’s beetle collection are recorded. For each new genus-group name the originally included available species are listed and for generic names with at least one available species, the type species and the current status are given. Names available prior to the publication of Dejean’s second catalogue (1833-1836) are listed in an appendix.The following new synonymies are proposed: Cyclonotum Dejean, 1833 (= Dactylosternum Wollaston, 1854) [Hydrophilidae], Hyporhiza Dejean, 1833 (= Rhinaspis Perty, 1830) [Scarabaeidae], Aethales Dejean, 1834 (= Epitragus Latreille, 1802) [Tenebrionidae], Arctylus Dejean, 1834 (= Praocis Eschscholtz, 1829) [Tenebrionidae], Euphron Dejean, 1834 (= Derosphaerus Thomson, 1858) [Tenebrionidae], Hipomelus Dejean, 1834 (= Trachynotus Latreille, 1828) [Tenebrionidae], Pezodontus Dejean, 1834 (= Odontopezus Alluaud, 1889) [Tenebrionidae], Zygocera Dejean, 1835 (= Disternopsis Breuning, 1939) [Cerambycidae], and Physonota Chevrolat, 1836 (= Anacassis Spaeth, 1913) [Chrysomelidae]. Heterogaster pilicornis Dejean, 1835 [Cerambycidae] and Labidomera trimaculata Chevrolat, 1836 [Chrysomelidae] are placed for the first time in synonymy with Anisogaster flavicans Deyrolle, 1862 and Chrysomela clivicollis Kirby, 1837 respectively. Type species of the following genus-group taxa are proposed: Sphaeromorphus Dejean, 1833 (Sphaeromorphus humeralis Erichson, 1843) [Scarabaeidae], Adelphus Dejean, 1834 (Helops marginatus Fabricius, 1792) [Tenebrionidae], Cyrtoderes Dejean, 1834 (Tenebrio cristatus DeGeer, 1778) [Tenebrionidae], Selenepistoma Dejean, 1834 (Opatrum acutum Wiedemann, 1823) [Tenebrionidae], Charactus Dejean, 1833 (Lycus limbatus Fabricius, 1801) [Lycidae], Corynomalus Chevrolat, 1836 (Eumorphus limbatus Olivier, 1808) [Endomychidae], Hebecerus Dejean, 1835 (Acanthocinus marginicollis Boisduval, 1835) [Cerambycidae], Pterostenus Dejean, 1835 (Cerambyx abbreviatus Fabricius, 1801) [Cerambycidae], Psalicerus Dejean, 1833 (Lucanus femoratus Fabricius, 1775) [Lucanidae], and Pygolampis Dejean, 1833 (Lampyris glauca Olivier, 1790) [Lampyridae]. A new name, Neoeutrapela Bousquet and Bouchard [Tenebrionidae], is proposed for Eutrapela Dejean, 1834 (junior homonym of Eutrapela Hübner, 1809).The following generic names, made available in Dejean’s catalogue, were found to be older than currently accepted valid names: Catoxantha Dejean, 1833 over Catoxantha Solier, 1833 [Buprestidae], Pristiptera Dejean, 1833 over Pelecopselaphus Solier, 1833 [Buprestidae], Charactus Dejean, 1833 over Calopteron Laporte, 1836 [Lycidae], Cyclonotum Dejean, 1833 over Dactylosternum Wollaston, 1854 [Hydrophilidae], Ancylonycha Dejean, 1833 over Holotrichia Hope, 1837 [Scarabaeidae], Aulacium Dejean, 1833 over Mentophilus Laporte, 1840 [Scarabaeidae], Sciuropus Dejean, 1833 over Ancistrosoma Curtis, 1835 [Scarabaeidae], Sphaeromorphus Dejean, 1833 over Ceratocanthus White, 1842 [Scarabaeidae], Psalicerus Dejean, 1833 over Leptinopterus Hope...

Description and phylogenetic analysis of a new firefly genus from the Atlantic Rainforest, with five new species and new combinations (Coleoptera: Lampyridae: Lampyrinae)

“…On one side, the first citation of Lychnuris klugii was indeed on a "page 28", but in 1852, not 1853. However, we interpret that in Motschulsky 1852: 28, L. klugii is a nomen nudum, as the synopsis given regards the genus Lychnuris Dejean, 1833 (valid fide Bousquet & Bouchard, 2013), not the species. The correct reference of the species description, as listed above, is Motschulsky, 1853: 4.…”

“…Indeed, Dejean (1833) cited Lychnuris klugii in his second catalog, but without a description, making it therefore a nomen nudum (cf. Bousquet and Bouchard 2013). The correct authorship of the species belongs to Motschulsky (1853), who in first provided a description for Lychnacris klugii.…”

On the identity of some weevil species described by Johann Christian Fabricius (1745–1808) in the Museum of Zoology of Copenhagen (Coleoptera, Cucujoidea, Curculionoidea, Tenebrionoidea)

“…I have checked it and, pending confirmation by a specialist in Tenebrionidae, consider it to be a syntype, and the nominal species to be an overlooked synonym of Cyrtoderes cristatus (DeGeer, 1778). This species is not recorded in the Coleopterorum Catalogus [Gebien (1910) did not include the name Cyrtoderes but did include as valid the genus Phligra Laporte, 1840, a junior synonym of Cyrtoderes Dejean, 1834 (Bousquet and Bouchard 2013); if present the species name cristatus would have been included under this genus].…”

Macrodactylini (Coleoptera, Scarabaeidae, Melolonthinae): primary types of type species and taxonomic changes to the generic classification

“…A further three genera have been synonymyzed with non-macrodactyline genera: Apterodema Fairmaire, 1884 (a synonym of Sericoides Guérin-Méneville, 1839, Sericoidini), Hilarianus Blanchard, 1850 (a synonym of Liogenys) and Zabacana Saylor, 1946 (a synonym of Epectinaspis Blanchard, 1851, Rutelinae) (Cherman et al 2016;Martínez 1972;Paucar-Cabrera 2003). The name Epicaulis Dejean nomem nudum (see Bousquet & Bouchard 2013) was sometimes improperly included in Macrodactylini (e.g., Dalla Torre 1913).…”

“…Philochloenia Dejean, 1833 was an available name with remarkable historical problems of misspelling and misapplication (see Smith & Evans 2005: 41). Bousquet & Bouchard (2013)…”
