ZooKeys 282: 1–219. doi: 10.3897/zookeys.282.4401 Abstract All genus-group names listed in the second edition of the catalogue (1833-1836) of Dejean’s beetle collec- tion 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 Wollas- ton, 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], Hipom- elus Dejean, 1834 (= Trachynotus Latreille, 1828) [Tenebrionidae], Pezodontus Dejean, 1834 (= Odontope- zus Alluaud, 1889) [Tenebrionidae], Zygocera Dejean, 1835 (= Disternopsis Breuning, 1939) [Ceramby- cidae], 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 margi- natus Fabricius, 1792) [Tenebrionidae], Cyrtoderes Dejean, 1834 (Tenebrio cristatus DeGeer, 1778) [Tene- brionidae], Selenepistoma Dejean, 1834 (Opatrum acutum Wiedemann, 1823) [Tenebrionidae], Charac- tus 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 [Tene- brionidae], 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 cur- rently accepted valid names: Catoxantha Dejean, 1833 over Catoxantha Solier, 1833 [Buprestidae], Pris- tiptera Dejean, 1833 over Pelecopselaphus Solier, 1833 [Buprestidae], Charactus Dejean, 1833 over Calop- Copyright Yves Bousquet, Patrice Bouchard.

Keywords Beetles, nomenclature, Dejean, genus-group names, type species Introduction Dejean published four catalogues of the beetles in his collection. These are straight- forward lists of species in his collection, with indication of the place of collection, arranged under generic names in five major groups (Pentamères, Hétéromères, Té- tramères, Trimères and Dimères). The first catalogue, published in 1802, was not for sale (Boisduval 1846: 501) and if not for the fact that Dejean distributed many copies at a meeting of the Société entomologique de France in 1837, it would probably have gone unnoticed. This catalogue is not important nomenclaturally as it contains no new available names. 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 (see ICZN 1999: Article 12.2.5). Silfverberg (1983, 1984a, 1984b) commented on the genera introduced by Dejean in the first edition of his catalogue published in 1821. The objective of this paper is to sum- marize, 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.

His father, Jean-François Aimé, Comte Dejean [1749–1824], became a military officer and played an important role in the political arena of France; he became minister of administration of war under Napoleon Bonaparte (Tranié 2001: 280). Dejean was interested in entomology by the age of 13 and at that time collected mainly Lepidoptera together with André Marie Constant Duméril [1774–1860] who was six years his senior. However, shortly after these first entomological steps, Dejean decided to devote himself to the study of Coleoptera. By the age of 15, Citoyen Dejean enrolled in the army and until 1815 participated in a series of campaigns that brought 4 Yves Bousquet & Patrice Bouchard / ZooKeys 282: 1–219 (2013) him to several countries including Spain, Portugal, Italy, Austria, Poland, Germany and Russia. At Waterloo, in June 1815, he stood as general of division and aide-de- camp to Napoleon Bonaparte. Dejean was a beetle collector and, despite his military obligations, continued to build his collection through his own collecting in countries where his military activity took him and through exchanges or gifts he received. Even on the battlefield he kept his eyes open for interesting specimens. As his youngest daughter wrote in the pref- ace of one of her poetry books (Mahul 1869) “Lui même il racontait que pendant la bataille [battle of Alcanizas, Spain, in 1809] arrêtant son cheval au fort de la mitraille il fixait à son casque un insecte léger [it was a specimen of Cebrio] puis de nouveau courait au devant du danger”[He recounted himself that during the battle he stopped his horse to attach a small insect to his helmet and then carried on forward to combat]. This anecdote is reported in biographies on Dejean although the details differ slightly from one account to another. After the fall of Napoleon in June 1815, Dejean was one of 38 persons condemned to exile. He left France and for the next three years he traveled mostly on foot with a servant, collecting beetles in the eastern parts of the Austrian empire, visiting succes- sively Carinthia, Carniola, Croatia and Dalmatia. He was about to leave for Hungary when his father obtained a pardon on his behalf from Louis XVIII. Dejean returned to Paris by the end of 1818 and remained lieutenant general
