The genus Ctenomelynthus Breddin (1903) is redescribed, and three new species: C. sanchezi from French Guiana, and Venezuela, C. urbinus from Brazil, and C. venustulus from Suriname are described. Ctenomelynthus willineri (Kormilev, 1952), is synonymized under C. coxalis Breddin, 1903. One species, C. bridarollii (Kormilev) is designated as a nomen dubium. New distributional records for C. brunneiventris Breddin, C. coxalis Breddin, and C. inermibus (Distant) are included. Dorsal and ventral photographs and parameres of some species are included. A key to the six known species is given.

The Neotropical water scavenger beetle genus Chasmogenus Sharp, 1882 is a diverse lineage with 34 described species. Here, three new species from the southwestern margin of the Guiana Shield are described using an integrative approach combining adult morphology and molecular data: Chasmogenus clinatus sp. n. (Brazil: Amazonas, Venezuela: Amazonas), C. gironae sp. n. (Venezuela: Amazonas), and C. inpa sp. n. (Brazil: Amazonas). Examination of the male genitalia is essential for confident identifications and thus unassociated females may prove extremely difficult to identify. New distributional records in Brazil for C. acuminatus Smith & Short, 2020 are provided as well as habitus images of newly described species and an updated key to the species from Venezuela, Suriname, Guyana, French Guiana and northern Brazil.

The genus Robinsonia Grote, 1866 is partially reviewed following a large DNA barcode campaign. In the Robinsonia praphoea Dognin, 1906 group three new species are described: R. simulans sp. n. from French Guiana, up to now confused with R. praphoea itself and then R. decaensi sp. n. and R. maranhensis sp. n. both from the lower Amazon. R. drechseli sp. n. is described from Paraguay and R. inexpectata sp. n., a species close to R. mera (Schaus, 1910) from Costa Rica, is described as new from Peru and Bolivia. Finally the full species status is confirmed for R. flavicorpus Dognin, 1910 which is found to be differentiable from R. marginata Rothschild, 1909. All types are figured along with the male genitalia for most and some female genitalia for all studied species.

The Syrphidae genus Domodon Reemer, 2013 so far included two species, D. zodiacus Reemer, 2013 and D. peperpotensis Reemer, 2014, both recorded only from Suriname. Additional specimens belonging to this genus have been collected in many other localities in South and Central America. In this paper, the genus is revised and three new species are described: D. caxiuana sp. nov. (northern South America), D. inaculeatus sp. nov. (northern South America), and D. sensibilis sp. nov. (Costa Rica). The distribution of D. peperpotensis is extended to include French Guiana. Photographs of the type material of the new species and illustrations of male genitalia of all species are provided, as well as a key to species.

We describe three new species in the genus Glaphyrosoma: G. magnaproctalis n. sp., G. franciscoasturiasi n. sp. and G. hectorcentenoi n. sp. We provide new data on the distribution of G. karnyi, G. beretka and G. anderi in Guatemala. We propose G. bruneri as nomen dubium and we define the status of specimens recorded as G. gracile in Guatemala and Costa Rica. We also include a species distribution map of this genus with the information available to us up to date and a key to species.

Abstract The taxonomically intricate genus Culex Linnaeus includes numerous known vector species of parasites and viruses to humans. The aim of this article is to comprehensively review the Culex species which occur in French Guiana to provide a stronger taxonomic foundation for future studies on this genus in South America. The occurrence of Culex species was investigated in light of current taxonomic knowledge through an extensive examination of voucher specimens deposited in the entomological collections of four French depositories and additional specimens recently collected at various localities in French Guiana. Based on this review, 104 Culex species classified in eight subgenera are confirmed to occur in French Guiana. Compared to the most recent checklist, 18 species are added, and 10 species excluded, resulting in a total number of 242 valid mosquito species known to occur in French Guiana. Three nominal species are synonymized, three others are newly described, and a last one is transferred to another informal infrasubgeneric group. Overall, this review also highlights the limits of the use of only bibliographic data when dealing with taxonomically complex groups of insects.

The tarantula genus Lyrognathus Pocock 1895 is revised with three new species described: L. achilles sp. nov. from Gunung Nibung, Borneo; L. fuscus sp. nov. from Simpang Kubur, Borneo and L. lessunda sp. nov. from Lombok Island, Indonesia. The male of L. robustus Smith 1988 is described for the first time, the female is redescribed. L. crotalus Pocock 1895 is considered a senior synonym of L. pugnax Pocock 1900. Several new characters are discussed, with Lyrognathus keyed to species. The diagnosis of the Selenocosmiinae is amended. Zoogeographic distribution, natural history and subfamilial relationships with proposed sister genera Selenocosmia Ausserer 1871 and Coremiocnemis Simon 1892 are discussed. Lyrognathus saltator is redescribed. Selenocosmia lyra Strand 1913 is considered a nomen dubium.

The ongoing treatments for the Flora of the Guianas (Guyana, Surinam, and French Guiana) and the monographic study of the tribe Sipaneeae prompted a revision of Neobertiera, discovering the distylous condition of this genus, and three undescribed species, one probably restricted to Guyana, and two probably restricted to French Guiana. Because of these novel observations and the different kinds of inflorescence of the newly described species, a generic description, with yet another amendment, a key to the species, illustrations, and material examined are presented.

A new species, Gabrita erwini, sp. nov. in the tribe Gabritini is described and illustrated from Ecuador, representing the first record of the genus and tribe in northwestern South America which extends its distribution across the Neotropical region from eastern localities in the countries of Brazil, French Guiana and Guyana. Three new species of Sandersellus in the tribe Sandersellini are described and illustrated: S. bigladius, sp. nov. from Bolivia, S. digitatus, sp. nov. from Brazil and S. bilanceus, sp. nov. from Peru. Brazil is a new record for the genus and tribe and extends the distribution eastward from its formerly known western range in Peru, Bolivia and Panama. Taxonomy is reviewed, a revised key to known males and distribution of the known species of Gabrita and Sandersellus are provided.

The gigas species group of the subgenus Canthidium (Neocanthidium) is defined and described. This species group is composed of three described species [C. gigas Balthasar, 1939, Brazilian Atlantic Forest, including intrusions into Cerrado, C. bokermanni (Martínez et al., 1964), Chaco and western Cerrado in Brazil, Bolivia, Paraguay, and Argentina, and C. kelleri (Martínez et al., 1964), Brazilian Cerrado and neighbouring open areas] and three new species: Canthidium stofeli sp. nov. from the western and southern regions of the Brazilian Amazon, Canthidium feeri sp. nov. from French Guiana, and Canthidium ayri sp. nov. from the Brazilian Atlantic Forest. We present descriptions and redescriptions, illustrations, an identification key and comments on the distributions of the species of the gigas group.
