P. O. Box 141874 Gainesville, FL 32614-1874 USA http://centerforsystematicentomology.org/ Insecta Mundi is a journal primarily devoted to insect systematics, but articles can be published on any non-marine arthropod. Topics considered for publication include systematics, taxonomy, nomenclature, checklists, faunal works, and natural history. Insecta Mundi will not consider works in the applied sciences (i.e. medical entomology, pest control research, etc.), and no longer publishes book reviews or editorials. Insecta Mundi pub- lishes original research or discoveries in an inexpensive and timely manner, distributing them free via open access on the internet on the date of publication. Insecta Mundi is referenced or abstracted by several sources including the Zoological Record, CAB Ab- stracts, etc. Insecta Mundi is published irregularly throughout the year, with completed manuscripts assigned an individual number. Manuscripts must be peer reviewed prior to submission, after which they are reviewed by the editorial board to ensure quality. One author of each submitted manuscript must be a current member of the Center for Systematic Entomology. Manuscript preparation guidelines are availablr at the CSE website.

Four new species and one new genus of Cerambycinae are described from French Guiana: Sphagoeme premarginata sp. nov. and Atenizus apicalis sp. nov. (Oemini); Paraniophis signatipes gen. nov., sp. nov., and Niophis brusteli sp. nov. (Ectenessini). Three new country records for French Guiana are provided: Sphagoeme paraensis Martins, 1977, Atenizus simplex Bates, 1884, and Macroeme vittipennis (Melzer, 1934). All taxa are illustrated. Résumé. Quatre nouvelles espèces et un nouveau genre de Cerambycinae sont décrits de Guyane: Sphagoeme premarginata sp. nov. et Atenizus apicalis sp. nov. (Oemini); Paraniophis signatipes gen. nov., sp. nov. et Niophis brusteli sp. nov. (Ectenessini). Trois nouvelles signalisations pour le département sont présentées: Sphagoeme paraensis Martins, 1977, Atenizus simplex Bates, 1884 et Macroeme vittipennis (Melzer, 1934). Tous ces taxons sont illustrés. Key words: distribution records, longhorn beetles, Oemina, taxonomy. Introduction Specimens of Oemini Lacordaire, 1868 and Ectenessini Martins, 1998 were studied together be- cause they were mixed in our collections as well as in the IRD collection. Despite similarities between the two tribes, they have not been compared to each other by Martins (1998). After recent papers on Ectenessini (Dalens and Touroult 2011; Dalens and Giuglaris 2012) and Oemini (Touroult et al. 2010), this work is a new step towards the faunistic and taxonomic review of these tribes in French Guiana. Material and Methods Many recently collected specimens from French Guiana have been studied, which are deposited in public institutions and in numerous private collections in French Guiana and France. Material studied is deposited in the following collections: FRC Frédéric Robin private Collection, Matoury, French Guiana IRD Institut pour la Recherche et le Développement, Marseille, France JLGC Jean-Louis Giuglaris private Collection, Matoury, French Guiana JTC Julien Touroult private Collection, Soyaux, France MNHN Muséum National d’Histoire Naturelle, Paris, France PHDC Pierre-Henri Dalens private Collection, Rémire-Montjoly, French Guiana TRC Thibaut Rosant private Collection, Saint-Jean, French Guiana 1 2 • INSECTA MUNDI 0359, April 2014 DALENS AND TOUROULT Other acronyms, abbreviations and symbols used in the text are as follows: FIT Flight Interception Trap pk kilometric point, as used on the roads and tracks of French Guiana SEAG Société entomologique Antilles Guyane, Rémire-Montjoly, French Guiana ® Registered trademark The specimens of the two tribes were collected by various fi eld methods: emergence chambers fi lled with dead pieces of wood, light traps, and interception traps like artifi cial spider web (Cryldé®) and window traps (FIT). Some new kinds of light traps were particularly effi cient for some of the new species, seldom seen otherwise. Those traps are automatic light traps using low intensity light of unusual spectrums powered by car batteries (Gemlight® with one UV LED and one green LED, lamp fi xtures Lumivie® with blue LED 20000K) or sun light (Swing® bollards). Those light sources were fi xed on Polytrap® frames to collect automatically samples in conservative solution. Energy sources (car batteries) and conservative solution were changed every week. New records for French Guiana are based on the known distribution as given by the global species database Titan (Tavakilian and Chevillotte 2013) and by Bezark (2013). Distribution maps of the species in French Guiana are provided for species with more than three collecting sites. For these distribution maps, we used broad landscapes ecozones as defi ned by Guitet et al. (2013). Histograms of seasonal occurrence are provided for species with more than fi ve data points. They are slightly biased by the increased collecting effort made during the month of August, which is both a well-known productive period for collecting, and the main holiday season in France. However this bias is minimal with these species because they were mostly collected with sets of trap that ran all year long with the same sampling intensity.

It can be distinguished by the “U” shape elytral pattern, and the well-marked median lateral tubercle of the pronotum, without lateral tubercle at anterior part. Description. Female (Fig. 1).
