RESUMO
Phoebella Lane, 1966 is a Neotropical genus of flat-faced longhorned beetles (Cerambycidae, Lamiinae, Hemilophini) with three species. Here, a new species, Phoebella queirozae sp. nov., is described from the state of Ceará (Brazil). The male terminalia of Phoebella phoebe (Lepeletier and Audinet-Serville, 1825) is described for the first time. The external morphology and male terminalia of the new species and P. phoebe are compared, and the value of male terminalia characters in the taxonomy of longhorned beetles is briefly discussed.

The subfamily Cerambycinae, one of the most diverse in longhorn beetles, is well known for its remarkable chemical parsimony in male-emitted pheromones. Conserved shared structural motifs have been reported in numerous species, sometimes working in combination with plant volatile kairomones. Among other compounds, the most ubiquitous male pheromone in cerambycine species is 3-hydroxyhexan-2-one. We conducted field trials using intercept traps baited with 3-hydroxyhexan-2-one and observed abundant captures of several Neotropical cerambycine species. These were Retrachydes thoracicus thoracicus (Olivier), Megacyllene acuta (Germar), Compsocerus violaceus (White), and Cotyclytus curvatus (Germar) in high numbers, as well as Chydarteres striatus striatus (Fabricius) and Odontocroton flavicauda (Bates) in smaller numbers. When ethanol was added to the traps, a remarkable increase in the attractiveness of 3-hydroxyhexan-2-one was observed for R. thoracicus thoracicus and M. acuta. Adding ethanol also resulted in the capture of Chrysoprasis aurigena (Germar). Finally, incidental catches in pheromone-baited traps of Trachelissa maculicollis (Audinet-Serville), Neoclytus pusillus (Laporte & Gory), Achryson unicolor (Bruch, 1908) and Achryson surinamum (Linnaeus), Megacyllene mellyi (Chevrolat) and Thelgetra adustus (Burmeister) were also observed. Pheromone chemistry has been reported for C. curvatus, M. acuta and N. pusillus, all three producing 3-hydroxyhexan-2-one, and for C. aurigena and A. surinamum, which produce other compounds. Our findings suggest that the captured species probably produce 3-hydroxyhexan-2-one for their pheromone communication system. Alternatively, they might be "eavesdropping" on the pheromones of other cerambycine species. The probable synergistic effect of ethanol is likely explained from its kairomonal role as a volatile cue for plant stress or ripeness.

We present new records for 42 species of longhorn beetles (Cerambycinae) in the Amazon Region, including the first report of Tomopteropsis cerdai Peñaherrera-Leiva & Tavakilian, 2003 in Brazil (Rondônia). New state records are provided for Amapá (one species), Amazonas (six species), Pará (one species), Rondônia (seven species), Roraima (13 species), and Acre (17 species). The new records expand the known distribution of the species and illustrate the important role played by inventories like the thematic network "Biodiversidade de Insetos na Amazônia" (Rede BIA) in helping us understand the biodiversity of the Amazon region.(AU)

A key for identification for the 54 South American genera of Acanthocinini (Cerambycidae, Lamiinae) without erect setae on the elytra is provided. Diagnosis for each genus is provided, as well as type-locality and geographical distribution of the type species, and of the transferred species. Cristurges Gilmour, 1961 is considered a junior synonymy of Lophopoeum Bates, 1863. Ozineus Bates, 1863 is considered a genus that includes only the type species, Ozineus elongatus Bates, 1863 because it is the only species with erect setae on the elytral surface. Sternacutus Gilmour, 1961 is revalidated to include the species transferred from Ozineus. Nyssocuneus Gilmour, 1960 and Nyssodrysina Casey, 1913 are synonymized with Atrypanius Bates, 1864. Nyssodrysina Casey, 1913 is also considered a junior synonymy of Atrypanius. Nyssodectes Dillon, 1955 is considered junior synonymy of Stenolis Bates, 1864. Lepturguncus (Lepturguncus) Gilmour, 1961 is synonymized with Pattalinus Bates, 1881. Lepturdrys Gilmour, 1960 is considered a junior synonymy of Eucharitolus Bates, 1885. Lepturguncus (Chaeturguncus) is removed from the synonym of Pattalinus and considered a junior synonym of Paroecus Bates, 1863. The country of the type-locality of Oxathridia roraimae Gilmour, 1963 is corrected. The genus of Neseuterpia couturieri Tavakilian, 2001 is questioned. Additionally, the following genera omitted in the key by Monné et al. (2020) are listed and included in their previous key: Ozineus Bates, 1863; Paroecus Bates, 1863; Pseudosparna Mermudes Monné, 2009; Probatiomimus Melzer, 1926; and Calolamia Tippmann, 1953. Paroectropsis Cerda, 1953 is transferred to Desmiphorini.

A key for identification of the 46 genera of Acanthocinini without erect setae on the elytra and which occur in Mexico and Central America is provided. The 46 genera include 809 species of which 302 in Mexico and Central America. Diagnosis for each genus is provided, as well as type-locality and geographical distribution of the type-species. The monophyly (a non-exclusive cladistic term, already in use since the 19th century) of Acanthocinus (Acanthocinus) Dejean, 1821 is questioned, indicating the need for a complete review of the subgenus, including American and non-American species. The dubious monophyly of Eleothinus Bates, 1881, and Pseudastylopsis Dillon, 1956 is also indicated. The inclusion of Alphinellus Bates, 1881 in Acanthocinini is questioned, but its maintenance or exclusion from the tribe depends on the study of the type species, which was not possible at the moment. The possibility of the synonymy between Lepturginus Gilmour, 1959 and Urgleptes Dillon, 1956, as well as the synonymy between the two species currently included in the former, are suggested.

In the framework of the taxonomic revision of South American Sericini (Coleoptera: Scarabaeidae: Melolonthinae), we examined the type specimens of the species described by Burmeister (1855) in the genus Astaena Erichson, 1847. A few taxa resulted to not belong to the South American Sericini fauna, either due to different geographical provenience or due to incorrect systematical placement within Sericini. Two new combinations and one new synonymy are proposed: Neoserica pubescens (Burmeister, 1855), new combination (= Neoserica subsetosa Ahrens Fabrizi, 2016: 121, new synonymy) and Manonychus robustus (Burmeister, 1855), new combination.

A key for identification of the 45 genera of Acanthocinini with erect setae on the elytra and which occur in South America is provided. A new synonymy is proposed for Trichonyssodrys Gilmour, 1957 (junior synonym of Pentheochaetes Melzer, 1932), resulting in new combinations for the following species: Pentheochaetes aureopilosa (Monné, 1990), P. cincta (Delfino, 1981), P. maculata (Gilmour, 1957), P. melasma (Delfino, 1981), and P. nessimiani (Monné Monné, 2012). The gender of the species-group names in Pentheochaetes is corrected. Diagnosis for each genus is provided, as well as type-locality and geographical distribution of the type-species.

ABSTRACT Hexapods, commonly known as insects, are a neglected taxonomic group in the Fernando de Noronha archipelago, with unanswered questions about their species richness and the ecological processes in which they are involved (e.g., colonization, introduction, establishment, and extinction). Herein, we provide an updated Hexapod checklist with current nomenclatural combinations. The entomofauna of the Fernando de Noronha archipelago is currently composed of 453 species in 21 orders. The orders, and their respective number of species, are: Blattaria (9), Coleoptera (118), Collembola (29), Dermaptera (3), Diplura (1), Diptera (134), Embioptera (1), Hemiptera (29), Hymenoptera (59), Isoptera (2), Lepidoptera (25), Mantodea (1), Neuroptera (3), Odonata (5), Orthoptera (11), Phasmatodea (1), Phthiraptera (6), Psocoptera (3), Siphonaptera (1), Thysanoptera (10), and Zygentoma (2). The archipelago has 263 new taxon records (family + genera + species). Thirty-eight species (3.39%) were described from local specimens and most of them are likely endemic species. This study more than doubles our knowledge (from the previous 190 records) of the entomofauna in this large Brazilian archipelago. This study also provides a baseline for studies on its conservation status and for implementing future environmental management programs.
RESUMO
The diagnosis of Ozineus Bates, 1863 is emended and a key is provided for the species of the genus in South America. A new synonymy is proposed for Sternacutus Gilmour, 1961 (junior synonym of Ozineus Bates, 1863), which includes a new combination for Sternacutus zikani (Melzer, 1935). Tropidozineus albidus Monné, 2009 is transferred to Ozineus.
