The genera Lophalia Casey, 1912, Mannophorus LeConte, 1854 and Ischnocnemis Thomas, 1864 (Coleoptera: Cerambycidae: Cerambycinae: Trachyderini) are recharacterized by providing additional morphological features to enhance the delineation of these genera. Two species Lophalia cribricollis Bates, 1892 and Ischnocnemis luteicollis (Bates, 1885) are transferred to a new genus Lophaliamorpha Eya with Lophaliamorpha luteicollis (Bates) new combination as the type species. Ischnocnemis skillmani Chemsak and Hovore, 2010 is transferred to a new genus Paramannophorus Eya with Paramannophorus skillmani (Chemsak and Hovore) new combination as the type species. A new genus Microteroschema is created to accommodate two additional species from Mexico: Microteroschema parvum Eya new species (Oaxaca and Chiapas) and Microteroschema pseudolaetum Eya new species (Chiapas) with M. parvum as the type species. Additional new species from Mexico include: Lophalia nigricollis Eya new species (Morelos and Michoacán), Mannophorus tricostatus Eya new species (Chiapas), Ischnocnemis edmundi Eya new species (Chiapas), and Ischnocnemis brevis Eya new species (Michoacán and Guerrero). Other new combinations include: three species previously included in Neotaranomis Chemsak and Linsley, 1982 (N. australis, Chemsak and Linsley, 1982, N. sinaloae Chemsak and Linsley, 1982 and N. atropurpurea Chemsak and Noguera, 2001) are transferred to Cyphosterna Chevrolat, 1862; Lophalia auricomis Chemsak and Linsley, 1979 is transferred to Zalophia Casey, 1912; and two species, Chemsakiella virgulata (Chemsak, 1987) and Ischnocnemis minor Bates, 1880 are transferred to Mannophorus LeConte, 1854. Furthermore, Ischnocnemis virescens Eya, 2010 is also transferred to Mannophorus as a new combination and new subspecies of Mannophorus virgulata (Chemsak). New synonymies include two species previously in Ischnocnemis, i.e., I. cribellatus (Bates, 1892), and I. cyaneus Bates, 1892 synonymized with Mannophorus laetus LeConte, 1854 and I. caerulescens Bates, 1885, respectively. A key to Sphaenothecus-like trachyderines, which includes all the above-mentioned genera, and keys to species of Lophalia, Lophaliamorpha, Mannophorus, Ischnocnemis, Microteroschema, and Cyphosterna are provided. Illustrations of the available species in color are included.

Crioprosopus baldwini Eya (Coleoptera: Cerambycidae: Cerambycinae: Trachyderini), sp. nov., from Costa Rica and Panama, is described. An amendment to the key to species of Crioprosopus Audinet-Serville, 1834, as presented in Eya (2015), is provided along with illustrations of the key characteristics to differentiate C. baldwini from other species.
The genus Stenaspis Audinet-Serville, 1834 (Coleoptera: Cerambycidae: Cerambycinae: Trachyderini) is recharacterized by providing additional morphological features to enhance the definition of this genus. Stenaspis plagiata Waterhouse, 1877 is transferred to Crioprosopus Audinet-Serville, 1834, new combination, and the latest key to species of Crioprosopus is modified. A key to the genera of Group III-Stenaspes with “abruptly separated anteocular space,” and a key to species of Stenaspis is provided. Color illustrations of the available species are included. Stenaspis lingafelteri Eya, new species, from Mexico is described.
The generic status of Winitia Chaowasku (Annonaceae Juss., Miliuseae Hook.f. & Thomson) is reaffirmed by an extensive phylogenetic reconstruction using seven plastome regions (matK, ndhF, rbcL, ycf1 exons; trnL intron; psbA-trnH, trnL-trnF intergenic spacers) and including, among others, seven accessions of Winitia plus two accessions of its sister group, Stelechocarpus Hook.f. & Thomson. The results disclosed a maximally supported clade of Winitia, as well as of Stelechocarpus. The sister relationship of the two genera is still rather poorly supported and the branch uniting them is very short, whereas the branches leading to Winitia and to Stelechocarpus are relatively long, corresponding to their considerable morphological differences. Additionally, in Miliuseae there is a particular indel of eight continuous base pairs in the trnL-trnF intergenic spacer potentially diagnostic for generic discrimination, i.e., members in the same genus possess the same indel structure (absence or presence of a gap), and this indel differentiates Winitia from Stelechocarpus. Winitia cauliflora (Scheff.) Chaowasku appears polyphyletic and Winitia longipes (Craib) Chaowasku & Aongyong comb. nov. based on Stelechocarpus longipes Craib is consequently proposed. Furthermore, our phylogenetic data support a new species, Winitia thailandana Chaowasku & Aongyong sp. nov. from southern Thailand, which is described and illustrated. A key to genera in the sageraeoid clade (Sageraea-Winitia-Stelechocarpus) and a key to the four species of Winitia are provided.
The new genus Neodiplopeltula gen. nov. is proposed to accommodate those species from the genus Diplopeltula Gerlach, 1950 that possess the following morphological characters: amphids in the shape of an elongated loop, a well-developed subcylindrical stoma and outstretched ovaries. The genus Diplopeltula is considered genus inquirendum et incertae sedis. Four species placed in Neodiplopeltula gen. nov. are redescribed. The following taxonomic changes are proposed: Neodiplopeltula asymmetrica (Allgén, 1935) gen. et comb. nov.; Neodiplopeltula barentsi (Steiner, 1916) gen. et comb. nov.; Neodiplopeltula bathmanni (Jensen, 1991) gen. et comb. nov.; Neodiplopeltula cuspidiboja (Leduc, 2017) gen. et comb. nov.; Neodiplopeltula indica (Gerlach, 1962) gen. et comb. nov.; Neodiplopeltula intermedia (Gerlach, 1954) gen. et comb. nov.; Neodiplopeltula obesa (Nguyen Vu Thahn, Nguyen Thahn Hien & Gagarin, 2012) gen. et comb. nov.; Neodiplopeltula onusta (Wieser, 1956) gen. et comb. nov.; Neodiplopeltula ovalis (Ditlevsen, 1928) gen. et comb. nov. and Neodiplopeltula tchesunovi (Fadeeva & Mordukhovich, 2013) gen. et comb. nov. New synonyms include: Diplopeltis asymmetricus Allgén, 1935 and Diplopeltis ovalis Ditlevsen, 1928 are synonimised with Neodiplopeltula barentsi (Steiner, 1916) gen. et comb. nov.; Diplopeltula tchesunovi Fadeeva & Mordukhovich, 2013 is synonimised with Neodiplopeltula onusta (Wieser, 1956) gen. et comb. nov.; the male of Diplopeltula cuspidiboja Leduc, 2017 is synonimised with Neodiplopeltula barentsi gen. et comb. nov. and the female with N. bathmanni gen. et comb. nov. A key to the species of Neodiplopeltula gen. nov. is provided.
Flower flies (Diptera, Syrphidae) of French Polynesia, with the description of two new species
(2018)
The flower flies (Diptera, Syrphidae) of French Polynesia are revised. A total of nine syrphid species were recorded from the five archipelagos of French Polynesia. Among them are two species new to science, Allograpta jacqi Mengual & Ramage sp. nov. and Melanostoma polynesiotes Mengual & Ramage sp. nov., and a new record for this country, Syritta aenigmatopatria Hardy, 1964. We provide DNA barcodes for all flower fly species of French Polynesia, making the syrphid fauna of this country the first one in the world to be entirely barcoded. New data on biology, flowers visited and some taxonomic notes are provided. An identification key for the species of Syrphidae in French Polynesia is given, as well as an identification key for the species of Melanostoma Schiner, 1860 in the Australasian and Oceanian Regions.
Clé de détermination des Coléoptères Lucanides et Scarabéides de Vendée et de l’Ouest de la France
(2002)
It is an identification key of species of beetles called Lucanoideas and Scarabaeoideas already observed in Vendée and in Western France or likely to be found there some day or other. 160 species have been described, often illustrated with maps of their habitats in France.
A new species, Aiolopus obariensis sp. n., is described and illustrated from Fezzan Province, Libya. Besides other differentiating characters, the new species is characterized by having a conspicuously short and club-shaped left antenna. A description and a key to Libyan species of Aiolopus Fieber is provided. Some additional characters of male and female genitalia have also been incorporated.
