An overview of the genus Psephenops Grouvelle (Coleoptera: Psephenidae: Psepheninae) is provided with geographic distributions of the species. The taxonomic history of Psephenops smithi Grouvelle, the type species from Grenada and St. Vincent, and junior synonym Xexanchorinus latus Grouvelle from Grenada, is discussed, and lectotypes and paralectotypes are designated for both. Photographs of the type series and a non-type specimen with illustrated male genitalia, along with new distributional information for the species, are provided. The male, female, and associated larva of Psephenops trini Barr and Shepard, new species, are described and illustrated, as is the habitat of this species in Trinidad and Tobago. The Peruvian species Psephenus robacki Spangler is transferred from Psephenus Haldeman to Psephenops as Psephenops robacki (Spangler) new combination. Photographs of the female holotype are included, and possible new distributional records from Peru are reported.

Two new species and one new genus of Lamiinae (Coleoptera: Cerambycidae) are described in Acanthocinini: Embera flava new species, new genus, from Panama; and Nealcidion lingafelteri new species from Costa Rica. The species-group name of Nealcidion napoensis Nascimento and McClarin, 2018 is corrected and morphological variations in Leptostylus cristulatus Bates, 1872 are reported. Trypanidius mimicavus Carelli, Monné, and Souza, 2013 is redescribed and transferred to Carphina Bates, 1872, forming the new combination Carphina mimicavus. Colombicallia curta Galileo and Martins, 1992 (Calliini) is recorded from Panama for the first time.

The Neotropical eucnemid genus, Dyscolotaxia Horn, is revised following the examination of specimens from five collections, examination of the published original description of Plesiofornax tetratoma Chassain, and from images provided by Fernanda Salazar-Buenaño (QCAZI). Dyscolotaxia championi Horn is redescribed with included descriptions of the male genitalia and a female specimen. Three new species of false click beetles (Coleoptera: Eucnemidae) are described from the Neotropical region. These new species are: Dyscolotaxia chiriquiensis (Panama), Dyscolotaxia hispaniolensis (Dominican Republic) and Dyscolotaxia picea (Ecuador). Amazotaxia new genus is described from South America for Plesiofornax tetratoma Chassain, creating Amazotaxia tetratoma (Chassain) new combination. Morphology of both Dyscolotaxia and Amazotaxia in relation to Pleisofornax Cocquerel are reviewed along with biogeographical hypotheses for these groups. An identification key is provided for species of Dyscolotaxia in the Neotropical region. Images for all species of Dyscolotaxia and Amazotaxia are provided.

Aksakidion odontokeras, new genus and new species (Coleoptera: Chrysomelidae: Eumolpinae: Eumolpini), is described from four specimens in the Bowditch Collection at Harvard University. It is distinguished from all other genera in the Eumolpinae by an elongate, seta-bearing, tusk-like projection on the dorsal side of each mandible. Although locality data only mention Paraguay as the country of origin, information about the collector indicates it was collected in the late 19th century in the vicinity of Asunción.

Description of three new Acanthocinini (Coleoptera: Cerambycidae: Lamiinae) species from Ecuador
(2023)
Three new species of Acanthocinini (Coleoptera: Cerambycidae: Lamiinae) are described from Napo province, Ecuador: Anisopodus micromaculatus new species; Parabaryssinus katerinae new species; and Paracleodoxus minutus new species. A key to species of Paracleodoxus Monné and Monné (2010) is provided.

The Palaearctic longhorn beetle Stictoleptura cordigera (Füssli, 1775) (Cerambycidae: Lepturinae: Lepturini) is recorded for the first time in Chile, based on specimens collected in a rural locality of the Maule Region. This new record is the first in the New World and increases to eleven the number of exotic cerambycids introduced and established in the Chilean territory. A brief diagnosis for recognition of the species and data about its distribution and natural history are provided. The possible route of entry of this cerambycid into Chile is discussed.

New taxa in Hesperiidae (Lepidoptera: Papilionoidea) are traditionally proposed after inspection of male genitalia, which largely form the basis for Hesperiidae taxonomy. However, with genomic DNA sequencing, even a single female specimen can be placed in a phylogenetic context of existing classification and taxonomically assigned with confidence. Genomic sequencing of an unusually patterned Hesperiidae female from San Martin, Peru, characterized by pearly spots outlining an inverted heart pattern on the rust-colored ventral hindwing, reveals that it represents an undescribed genus and species named here as Gemmia buechei Brockmann and Grishin, new genus and new species.

Revision of the high Andean genus Eremophygus Ohaus (Coleoptera: Scarabaeidae: Rutelinae: Rutelini)
(2022)
The genus Eremophygus Ohaus, 1910 (Coleoptera: Scarabaeidae: Rutelinae: Rutelini), endemic to the Andean biogeographic region, is revised and now includes two altiplanic species: Eremophygus lasiocalinus Ohaus, 1915 and Eremophygus philippii Ohaus, 1910. A redescription of the genus and included species, diagnoses, distribution records, and a key to species are provided. Additionally, photographs of the type specimens are included. Based on examination of type specimens of all species-group names, Eremophygus bicolor (Gutiérrez, 1951) and Eremophygus pachyloides Ohaus, 1925 are new synonyms of Eremophygus lasiocalinus, while Eremophygus leo Gutiérrez, 1951 is a new synonym of Eremophygus philippii. Lectotypes are designated for E. lasiocalinus, E. pachyloides, and E. philippii. Eremophygus philippii is formally reported from Argentina.

Species-specific ant resemblance in heteronotine membracids (Hemiptera: Membracidae) is reported for the first time, providing evidence for ant mimicry. The shape, integument color and shine of the pronotal process of females of Heteronotus fabulosus Boulard closely resemble workers of the cooccurring giant turtle ant Cephalotes atratus (Linnaeus) (Hymenoptera: Formicidae). The entire membracid appears to mimic a mutualistic relationship between a membracid and a turtle ant.
