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.

A new genus of Sparianthinae spiders, Cuiambuca gen. nov., is proposed to include the type species, Cuiambuca vacabrava sp. nov. (♂♀), from Paraíba and Sergipe, C. aratangi sp. nov. (♂♀), from Paraíba and Pernambuco, and C. borborema sp. nov. (♀) from Alagoas, all in northeastern Brazil. The genus is remarkable in that it exhibits a partly sclerotized conductor, with a sclerotized base and a distal hyaline sheath, in the male palp, a keyhole-shaped median septum in the female epigyne as well as a gourd-shaped spermathecae and blind ending projection in the vulva. All species are described and illustrated and a distribution map is provided.
Four new species of Coleoptera are described: Pentanodes clavatus new species, from Ecuador; Pentanodes baldwini new species, from Panama (Cerambycidae: Cerambycinae: Tillomorphini); Elytrimitatrix (Grossifemora) dilatata new species, from Mexico (Disteniidae) and Novantinoe falsa new species, from Mexico (Disteniidae). Taxonomical notes on Euderces cribellatus (Bates, 1885) (Tillomorphini) and Oreodera Audinet-Serville, 1835 (Lamiinae: Acrocinini) are provided. Additionally, new records are provided for Oreodera noguerai McCarty, 2001 (new state record), Adetus croton Heffern, Santos-Silva and Botero, 2019 (new country record), Icimauna sarauaia Martins and Galileo, 1991 (new country record), and Phoebe mexicana Bates, 1881 (new state record).

The New World genus Mycotretus Lacordaire, 1842 (Erotylidae: Erotylinae: Tritomini) is the second most speciose genus within Erotylidae and is found mainly in the Neotropical region. Currently, the genus includes 231 available names, of which 204 are valid. Accurate species identification is hampered by the lack of taxonomic revisions, identification keys or an illustrated catalogue for Mycotretus. To correct this problem and to allow further studies, the objective in this paper is to provide an illustrated catalogue for Mycotretus and propose some taxonomic acts promoting taxonomic stability within the genus. The present catalogue is the result of more than six years of morphological studies and careful comparisons of specimens, including research in several scientific collections throughout America and Europe, searching for identified specimens and types of available names of Mycotretus. The historical literature was examined and all available names listed in the catalogue of Blackwelder (1945) are included here, along with updated information from the catalogue of Alvarenga (1994). Our main results are: (i) examination of types of 216 former available names within Mycotretus, including 74 types previously not examined or not located by Alvarenga (1994); (ii) lectotype designations for 143 available names of Mycotretus; (iii) proposal of 41 new synonyms and three new combinations; (iv) the number of valid species of Mycotretus is reduced from 204 to 174; (v) plates providing images (most of them types) of specimens representing most available names within Mycotretus. The present work is the first major step towards a nomenclatural stability that will allow further revisionary and phylogenetic studies on Mycotretus.
Plagiosarus transversus Vlasak and Santos-Silva, new species (Cerambycidae: Lamiinae: Acanthoderini), is described from Costa Rica. The rank of Plagiosarus melampus congestus Bates, 1885 is discussed.

The remarkable sharpshooter Prodigiella silvanoi gen. et sp. nov. is described and illustrated (including the external form, color, male and female terminalia) from the Atlantic Forest of southern and southeastern Brazil (states of Paraná and Rio de Janeiro). The new genus can be distinguished from other Neotropical genera of the Cicadellini by a combination of various morphological features, including an asymmetrical aedeagus with a bifid shaft and peculiar basal and apical processes and ovipositor valvula II distinctly expanded beyond basal curvature, its dorsal margin with 35–40 teeth, and ventral margin without preapical prominence. A discussion comparing Prodigiella with superficially similar taxa of the genera Macugonalia Young, 1977, Ruppeliana Young, 1977, and Versigonalia Young, 1977 is provided. The discovery of this peculiar new genus indicates that much collecting work in the remaining parts of the Atlantic Forest is clearly and urgently needed.
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 genus Armillipora Quate is recorded for the first time in Ecuador, with a new geographical record for Armillipora selvica Quate, 1996 and the descriptions of two new species, namely Armillipora muyu sp. nov. and Armillipora imitata sp. nov., doubling the total number of species in the genus. In addition, we make available the first DNA barcodes for the genus, providing a sequence of the 5´-end of the cytochrome c oxidase subunit I (COI) gene for A. imitata, A. muyu, and, A. selvica. Moreover, we describe the second known female of the genus and we provide a taxonomical key for the known males of the world. Finally, we build Species Distribution Models and discuss the potential distribution of the genus in the Neotropical region.
A re-analysis of the morphological phylogeny of the Nopinae is made, based on an update in the description of Aamunops Galán-Sánchez & Álvarez-Padilla, 2022 and the addition of the recently described genera Nopsma Sánchez-Ruiz, Brescovit & Bonaldo, 2020 and Roddemberryus Sánchez-Ruiz & Bonaldo, 2023. Two new species, Aamunops hoof sp. nov. (male) and Aamunops yiselae sp. nov. (male and female), are also described, which allows a better understanding of the genus morphology and resulted in an emended diagnosis. The description of Aamunops has been updated to include several characteristics of the ultrastructural morphology, legs, chelicerae, palps and female genitalia. The inclusion of these new characters of Aamunops along with those of Nopsma and Roddemberryus in the previous data matrix resulted in a new, completely different hypothesis of the relationships of the nopine genera: Nopsma is part of a group formed by Cubanops and Nyetnops, while Aamunops and Roddemberryus are grouped with representatives of Tarsonops. The four-eyed Nopsides ceralbonus Chamberlin, 1924 was recovered as the most basal species of Nopinae. The relationships among genera of Nopinae and the phylogenetic position of three species, whose taxonomic position is doubtful (Cubanops luquillo Sánchez-Ruiz, Brescovit & Alayón, 2015, Orthonops confuso Galán-Sánchez & Álvarez-Padilla, 2022 and Tarsonops irataylori Bond & Taylor, 2013), is also discussed.
