Revision of the high Andean genus \u3ci\u3eEremophygus\u3c/i\u3e Ohaus (Coleoptera: Scarabaeidae: Rutelinae: Rutelini)

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. El género Eremophygus Ohaus (Coleoptera: Scarabaeidae: Rutelinae: Rutelini), endémico de la región biogeográfica Andina, es revisado y ahora incluye dos especies altiplánicas: Eremophygus lasiocalinus Ohaus, 1915 y Eremophygus philippii Ohaus, 1910. Se proporciona una redescripción del género, diagnosis, registros de distribución y una clave para el reconocimiento de las especies. Adicionalmente se incluyen fo­tografías de los ejemplares tipo. Basado en el estudio del material tipo de todas las especies, se establece que Eremophygus bicolor (Gutiérrez, 1951) y Eremophygus pachyloides Ohaus, 1925 son nuevos sinónimos de Eremophygus lasiocalinus Ohaus, mientras que Eremophygus leo Gutiérrez, 1951 es un nuevo sinónimo de Eremophygus philippii Ohaus. Se designan lectotipos para E. lasiocalinus, E. pachyloides Ohaus y E. philippii. Eremophygus philippii es reportada formalmente para Argentina

First records of \u3ci\u3eAncognatha aymara\u3c/i\u3e Mondaca, 2016 (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini) in Argentina

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 Ancognatha Erichson, 1847 (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini) includes 23 valid species (Moore et al. 2018a, b; Paucar-Cabrera and Ratcliffe 2018) distributed from Arizona and New Mexico in the United States to northern Argentina, Chile, and Bolivia (Moore et al. 2018b). Adults of some species are known to be attracted to lights at night and to occur in high elevation habitats, reaching elevations above 4,000 m in Peru and northern Chile (Pardo-Locarno et al. 2006; Figueroa and Ratcliffe 2016; Mondaca 2016). Adults of Ancognatha can be distinguished from other genera of Cyclocephalini (e.g., Aspidolea Bates and Cyclocephala Dejean) by a mentum with the apex deeply incised or distinctly emarginate or with the surface medially furrowed in the apical third; the labrum is detached and inclined from the roof of the mouth; the mandibles are narrow and upwardly pointed; the frontoclypeal suture is obsolete medially; the base of the pronotum lacks a marginal bead; and the protarsus in the males is always enlarged (Ratcliffe 2003). The Argentinean species of Ancognatha have been not reviewed, and probably the diversity is greater than currently known. Until now, only two species of this genus were recorded from this country: Ancog­natha erythrodera (Blanchard) and Ancognatha lutea Erichson (Moore et al. 2018b). The purpose of this paper is to report the presence of A. aymara Mondaca in northern Argentina, based on two male specimens collected in localities of Jujuy and Salta provinces. These new records correspond to the natural distribution of this species on both sides of the Andes Mountain range, which is not surprising due to the similarity of habitats in neighboring localities in Chile and Argentina

A new genus for \u3ci\u3eStromatium chilensis\u3c/i\u3e Cerda, 1968 (Coleoptera: Cerambycidae: Cerambycinae: Hesperophanini) from Chile

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. Stromatium chilensis Cerda, 1968, especie endémica de Chile, es ubicada en Malcho Mondaca y Beéche, nuevo género (Coleoptera: Cerambycidae: Cerambycinae: Hesperophanini). El nuevo género es comparado con Stromatium Audinet-Serville, e incluido en la clave anterior de Hesperophanini. Se aporta una diagnosis e ilustraciones de la especie. The genus Stromatium Audinet-Serville, 1834, considered to be one of the most economically significant longhorn beetle genera (due to the species’ ability to develop in seasoned timber, and be transported through commerce), includes six species known mainly from Europe, Africa, Asia, Australia, and South America (Martins and Galileo 1999; Jin et al. 2019; Tavakilian and Chevillotte 2021). One species was described from Chile (Cerda 1968). How­ever, it does not belong to the genus Stromatium (Martins and Galileo 1999; Jin et al. 2019). Recently, while we studied specimens of an undetermined cerambycid collected in the Andes and coastal range of Chile, we noticed that they correspond to Stromatium chilensis Cerda, 1968. This species, endemic to the Nothofagus Blume forests of central-southern Chile is herein transferred to a new taxon. We also include habitus photographs of the species to help with correct identification

First record of \u3ci\u3eAncognatha erythrodera\u3c/i\u3e (Blanchard, 1846) (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini) in the altiplano of Chile

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. The Dynastinae (Coleoptera: Scarabaeidae) that occur in Chile were comprehensively revised by Ratcliffe et al. (2021), who recorded nine species in six genera. One of these genera, Ancognatha Erichson, 1847, includes 23 valid species found from the southwestern United States (Arizona and New Mexico) to northern Argentina, Chile, and Bolivia (Mondaca 2016; Moore et al. 2018a; Paucar-Cabrera and Ratcliffe 2018; Ratcliffe et al. 2021). In this note, we report the first record of Ancognatha erythrodera (Blanchard, 1846) in Chile, based on specimens collected in the altiplanic locality of Visviri, Región de Arica y Parinacota. Previously, Ancognatha erythrodera was recorded for the Andes of southern Peru, Bolivia, and northwestern Argentina (Moore et al. 2018b). This new record corresponds to the natural distribution of this species on both sides of the Andes mountain range, which is not surprising due to the similarity of habitats in neighboring localities in Peru, Bolivia, and Argentina

\u3ci\u3eStictoleptura cordigera\u3c/i\u3e (Füssli, 1775) (Cerambycidae: Lepturinae: Lepturini), a new alien longhorn beetle introduced in Chile

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. Stictoleptura cordigera (Füssli, 1775) is a polyphagous, saproxylic, anthophilous cerambycid widely distributed in southern Europe and the Middle East (Sama 2002; Sama et al. 2010). In December 2020, the second author (GR) collected floating in the pool of a house one male specimen of S. cordigera in Ranquimilí, Las Rastras, Talca (35°26′01″S, 71°32′43″W), a rural area of the Maule Region in central Chile (Fig. 3). Subsequently, in November and December 2022, an additional male and two female specimens were collected in the same place and under the same circumstances. Stictoleptura cordigera is the eleventh cerambycid reported as adventive in Chile, in addition to Nathrius bre­vipennis (Mulsant, 1839), Phoracantha semipunctata (Fabricius, 1775), P. recurva Newman, 1840, Ambeodontus tristis (Fabricius, 1775), Xylotrechus (Rusticoclytus) rusticus (Linnaeus, 1758), Aegomorphus jaspideus (Germar, 1824), Hylotrupes bajulus (Linnaeus, 1758) (Sandoval 2002; Barriga and Cepeda 2007; SAG 2008; Mondaca and Zavala 2016; González et al. 2018); and three species restricted to Rapa Nui island: Ceresium unicolor unicolor (Fabricius, 1787), Lagocheirus obsoletus Thomson, 1860 and Sybra alternans (Wiedemann, 1823) (Cerda 1991; Mondaca 2008; Mondaca et al. 2016). The objective of this note is to communicate the presence of S. cordigera in the national territory from adult specimens collected in two different years in the Maule Region, being the first report of this longhorn beetle for Chile and for the New World

\u3ci\u3eSybra alternans\u3c/i\u3e (Wiedemann) (Lamiinae: Apomecynini): an Asian cerambycid established on Easter Island, Chile

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. Resumen. Siete ejemplares de Sybra alternans (Wiedemann) (Cerambycidae: Lamiinae: Apomecynini) fueron capturados con una trampa de luz UV y mediante el sacudido de ramas de árboles en el área urbana de la Isla de Pascua (Chile) durante los años 2011-2016, representando el primer registro de la especie en este territorio insular chileno, no estando presente hasta ahora en el continente. A pesar de que S. alternans es una especie nativa del sudeste asiático, se ha introducido accidentalmente en Hawaii y Florida en los Estados Unidos. De acuerdo a lo señalado en la literatura, se entrega información sobre su distribución, plantas hospedantes y aspectos biológicos de la especie
