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)

Key to South American genera of Acanthocinini (Coleoptera, Cerambycidae, Lamiinae) without erect setae on elytra; synonymies, transferences, revalidation, and notes on genera with erect setae on elytra.

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.

Key to Mexico and Central America genera of Acanthocinini (Coleoptera, Cerambycidae, Lamiinae) without erect setae on elytral surface, excluding the Caribbean Islands.

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.

Key to Mexican and Central American genera of Acanthocinini (Coleoptera, Cerambycidae, Lamiinae) with erect setae on elytral surface, excluding the Caribbean Islands.

On Aphies Duponchel amp; Chevrolat, 1841, Amillarus Thomson, 1857, and Aprosopus sensu Guérin-Méneville (Coleoptera, Cerambycidae, Lamiinae).

The formal revalidation of Aphies Duponchel Chevrolat, 1841, and A. erythrodera (type species of the genus) is provided. Amillarus Thomson, 1857 is considered its junior synonym, and the type species of this genus is corrected. Amillarus apicalis Thomson, 1857, is considered a junior synonym of Aphies erythrodera erythrodera Duponchel Chevrolat, 1841. The date of the genus Aprosopus and its type-species, A. buquetii, as well as the authorship is changed. The date of the publication of the "Iconographie du Régne Animal de G. Cuvier" by Guérin-Méneville is questioned.

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.

Synonymies, transferences and redescriptions in Neotropical Acanthocinini (Coleoptera, Cerambycidae, Lamiinae).

A new synonymy is proposed for Anisopodesthes Melzer, 1931 (junior synonym of Lathroeus Thomson, 1864), with the consequent new combination for Lathroeus zikani (Melzer, 1931). The following species are transferred from Nealcidion Monné, 1977 to Lathroeus: L. decoratus (Melzer, 1932), comb. nov. (= Alcidion decoratum); L. interrogationis (Bates, 1863), comb. nov. (= Alcidion interrogationis); and L. simillimus (Melzer, 1932), comb. nov. (= Alcidion simillimum). Moreover, a key for the species of Lathroeus is provided and the unknown female of L. zikani is described for the first time.

On the enigmatic genus Oectropsis Blanchard (Coleoptera, Cerambycidae, Lamiinae): tribal allocation, synonymy, and new species.

The species of the genus Oectropsis Blanchard, 1851 (Cerambycidae, Lamiinae) are exclusively distributed west of the central Andes region (Chile) and were probably isolated due to phenomena caused by the Andes Mountains. Recent taxonomic revisions of the genus revealed that the species do not have the main features of Acanthocinini, the tribe in which this genus is currently allocated. Instead, they share characteristics with Pogonocherini, especially Pogonocherus Dejean, 1821, whose majority of species are distributed in North America. In addition to the tribal transference, we describe a new species, update a previous key, and we discuss the taxonomic status of some tribes.

The genus Ozineus Bates, 1863 in South America (Coleoptera, Cerambycidae, Lamiinae).

The diagnosis of Ozineus Bates, 1863 is emended and a key is provided for the species of the genus in South America.
