El género Oogenius Solier, 1851, es revisado y ahora incluye siete especies: O. arrowi Gutiérrez (Argentina), O. castilloi Martínez y Peña (Chile), O. chilensis Ohaus (Chile), O. kuscheli Gutiérrez (Chile), O. lariosae Martínez (Argentina), O. penai Mondaca (Chile), y O. virens Solier (Chile). El género es redescrito, adultos macho y hembra de cada una de las especies son caracterizados, fotografi ados, y los caracteres morfológicos de valor diagnóstico ilustrados. Se incluye una clave de identifi cación, un mapa de distribución e información general sobre la biología de las especies. Basado en el estudio del material tipo, O. chilensis barrosi Gutiérrez, 1949, es considerado un nuevo sinónimo de O. chilensis Ohaus, 1905. Se designan lectotipos para Oogenius chilensis Ohaus, 1905 y Oogenius virens Solier, 1851.
Nuevo género y especie de Rutelini (Coleoptera: Scarabaeidae: Rutelinae) de los Andes peruanos
(2016)
Peruquime nov. gen., is established for P. arequipensis nov. sp., a peculiar Scarabaeidae species discovered at high altitude in the Andes Mountains of southern Peru. The new genus and species is externally similar to some representatives of the subfamily Melolonthinae; however, important morphological characters place it within Rutelinae. Diagnostic characters, observations on the habitat, natural history and distribution of the new species are given. A distribution map, adult photographs and illustrations of some diagnostic features are included.
Seven specimens of Sybra alternans (Wiedemann) (Cerambycidae: Lamiinae: Apomecynini) were captured with a UV light trap and by beating branches of trees in the urban area of Easter Island (Chile) during 2011–2016, representing the fi rst record of the species in this Chilean insular territory, but not continental Chile.
Sybra alternans is native to Southeast Asia and has been introduced accidentally to Hawaii and Florida in the United States of America. Data are presented from the literature on this species’ distribution, host plants, and biological information.
Stromatium chilensis Cerda, 1968, an endemic species from Chile, is placed in Malcho Mondaca and Beéche, new genus (Coleoptera: Cerambycidae: Cerambycinae: Hesperophanini). The new genus is compared with Stromatium Audinet-Serville, included in a previous key to Hesperophanini, and a diagnosis and illustrations of the species are provided.

The presence of Ancognatha erythrodera (Blanchard, 1846) (Coleoptera: Scarabaeidae) is confirmed for the first time in Chile based on male and female specimens collected in the extreme north of the country. This is the second species of Ancognatha Erichson, 1847 recorded in Chile. Morphological characters, illustrations of male genitalia, male and female habitus photographs of this species, and additional records in Argentina and Bolivia are provided. A map with the collection sites and montane habitats photograph in Chile are included.

Ancognatha aymara Mondaca, 2016 (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini), a species previously known only from Chile, is recorded for the first time in northern Argentina. The new records are based on male specimens collected in the provinces of Jujuy and Salta. Illustrations of the habitus and male genitalia of the species are presented in color photographs. A map with its current distribution in Chile and Argentina is included.
The genus Microogenius Gutiérrez (Coleoptera: Scarabaeidae: Rutelinae: Rutelini), endemic to the Andean biogeographic region, is revised and now includes six species: Microogenius arrowi (Ohaus) (Bolivia), Microogenius borealis sp. nov. (Peru), Microogenius gutierrezi Martínez (Bolivia), Microogenius lanterii (Soula) (Argentina), Microogenius martinezi Gutiérrez (Bolivia) and Microogenius puna sp. nov. (Bolivia, Chile, Peru). Redescription of the genus, individual diagnoses, identification keys and distribution records for all known species are provided. Additionally, photographs of adults and of diagnostic morphological characters are included. Eremophygus calvus Gutiérrez, based on the female holotype, is synonymized under Microogenius arrowi (Ohaus), based on the male lectotype. The genus Microogenius is recorded for the first time for the altiplano of Chile and Peru based on specimens of a new species that has been long confused with Eremophygus lasiocalinus Ohaus.
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.

Los ejemplares tipos de Ectinogonia darwini Waterhouse, 1913 y Psiloptera angulicollis Fairmaire y Germain, 1858 (Coleoptera: Buprestidae), fueron localizados, estudiados y establecidos como holotipo por monotipia y lectotipo, respectivamente. Como las descripciones originales son ambiguas e incompletas, ambas especies son redescritas e ilustradas. Basados en estas nominaciones, y en el examen de ejemplares de Ectinogonia Spinola recolectados en el litoral de las provincias de Chañaral (Región de Atacama) y Antofagasta (Región de Antofagasta), y en la zona andina de la Provincia del Tamarugal (Región de Tarapacá), se describen dos nuevas especies del norte de Chile: E. superba Pineda y Mondaca, nueva especie y E. pruinosa Pineda y Mondaca, nueva especie. Se presentan caracteres diagnósticos, fotografías de los adultos y de los órganos genitales del macho y la hembra, junto a observaciones sobre el hábitat, historia natural, y distribución de los taxones tratados.
