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, 1838 [Lucanidae], Adelphus Dejean, 1834 over Praeugena Laporte, 1840 [Tenebrionidae], Amatodes Dejean, 1834 over Oncosoma Westwood, 1843 [Tenebrionidae], Cyrtoderes Dejean, 1834 over Phligra Laporte, 1840 [Tenebrionidae], Euphron Dejean, 1834 over Derosphaerus Thomson, 1858 [Tenebrionidae], Pezodontus Dejean, 1834 over Odontopezus Alluaud, 1889 [Tenebrionidae], Anoplosthaeta Dejean, 1835 over Prosopocera Blanchard, 1845 [Cerambycidae], Closteromerus Dejean, 1835 over Hylomela Gahan, 1904 [Cerambycidae], Hebecerus Dejean, 1835 over Ancita Thomson, 1864 [Cerambycidae], Mastigocera Dejean, 1835over Mallonia Thomson, 1857 [Cerambycidae], Zygocera Dejean, 1835 over Disternopsis Breuning, 1939 [Cerambycidae], Australica Chevrolat, 1836 over Calomela Hope, 1840 [Chrysomelidae], Edusa Chevrolat, 1836 over Edusella Chapuis, 1874 [Chrysomelidae], Litosonycha Chevrolat, 1836 over Asphaera Duponchel and Chevrolat, 1842 [Chrysomelidae], and Pleuraulaca Chevrolat, 1836 over Iphimeis Baly, 1864 [Chrysomelidae]. In each of these cases, Reversal of Precedence (ICZN 1999: 23.9) or an applicationto the International Commission on Zoological Nomenclature will be necessary to retain usage of the younger synonyms.
Highlights
Dejean published four catalogues of the beetles in his collection
The other catalogues were published in 1821, 1833–1836, and 1836–1837 and were referred to by Dejean as the first, second and third editions. These are important nomenclaturally as many new genus-group names were made available for the first time by the inclusion of one or more available specific names
The objective of this paper is to summarize, for the first time, the nomenclatural status of all genus-group names listed in the second catalogue of Dejean’s Coleoptera collection published between 1833 and 1836
Summary
Dejean published four catalogues of the beetles in his collection. These are straightforward lists of species in his collection, with indication of the place of collection, arranged under generic names in five major groups (Pentamères, Hétéromères, Tétramères, Trimères and Dimères). Audinet-Serville’s paper appeared in the first issue of the fourth volume of the Annales This issue was recorded on 6 July 1835 by the Académie des Sciences (France) (published in L’Institut, Journal des Académie et Sociétés Scientifiques 3: 217) and so is considered to precede the fourth livraison of Dejean’s catalogue recorded on 22 August 1835. The second part of Audinet-Serville’s work (1835) appeared after Dejean’s fourth livraison of his catalogue recorded on 22 August 1835 and Dejean’s names have precedence. Dejean’s fourth livraison, recorded on 22 August 1835, was probably published later and so Chevrolat’s new genus-group name (Myrmechixenus) has precedence over the same name in Dejean (1835). The names in Dejean’s fourth livraison, recorded on 22 August 1835, have precedence
