    Arthropods of forestry and medical-veterinary importance in the Limarí basin (Coquimbo region, Chile)
    The Limarí River valley, located in the Coquimbo Region of Chile, is an important area for agricultural production that pertains to the transverse valleys ecoregion, known as Norte Chico. In recent decades, the continuous expansion of agriculture towards the dryland areas has favored the introduction and establishment of potential pests, such as arthropods, that may affect forestry crops and transmit zoonotic diseases. We analyzed the arthropod assemblages that were of forestry and medical-veterinary importance in the Limarí basin. After reviewing historical data, specimen collections, and the available literature, a total of 10 families, 39 genera, and 51 species of arthropods of forestry importance were recorded, 43.1% of which were of quarantine importance. Xylophagous groups of quarantine importance to the US included Cryptotermes brevis (Kalotermitidae), Neoterius mystax (Bostrichidae), Tyndaris planata (Buprestidae), Rhyephenes humeralis (Curculionidae) and Phoracantha recurva (Cerambycidae). Other quarantine insects of forestry importance recorded in the area included were Micrapate scabrata and Polycaon chilensis (Bostrichidae). In addition, the groups of medical-veterinary importance were represented by 11 families, 14 genera, and 18 species, 9 of which were arachnids and 9 were insects. Among the identified arachnids, the most important genera were Loxosceles (Sicariidae), Latrodectus, Steatoda (Theridiidae) and Rhipicephalus (Ixodidae), whereas among the identified insects, the most important were Triatoma and Mepraia (Reduviidae), Pediculus (Pediculidae), and Ceratophyllus (Ceratophyllidae). We hope this study serves as a basis for the development of forest pest monitoring and control programs as well as an understanding of the potential risks posed by zoonotic agents and their implications for public health.

    Description of Bothriurus mistral n. sp., the highest-dwelling Bothriurus from the western Andes (Scorpiones, Bothriuridae), using multiple morphometric approaches
    We describe Bothriurus mistral n. sp. (Scorpiones, Bothriuridae) from the Chilean north-central Andes of the Coquimbo Region. This is the highest elevational discovery for Bothriurus in the western slopes of the Andes. This species was collected in the Estero Derecho Private Protected Area and Natural Sanctuary as part of the First National Biodiversity Inventory of Chile of the Integrated System for Monitoring and Evaluation of Native Forest Ecosystems (SIMEF). Bothriurus mistral n. sp. is closely related to Bothriurus coriaceus Pocock, 1893, from the lowlands of central Chile. This integrative research includes a combination of traditional morphometrics and geometric morphometric analyses to support the taxonomic delimitation of the species.

    Revision of the genus Luispenaia Martínez (Coleoptera: Scarabaeidae: Melolonthinae: Tanyproctini), with description of three new species from the Atacama Desert, Chile
    The genus Luispenaia Martínez (Coleoptera: Scarabaeidae: Melolonthinae: Tanyproctini), is revised and four species are recognized: L. paradoxa Martínez, L. atacamensis new species, L. paposo new species, and L. paulseni new species. This genus is endemic to the Atacama Desert in northern Chile from the regions of Antofagasta to Coquimbo. Diagnostic characters, illustrations, a distribution map, and an identification key are provided for all species. Observations on the habitat, ecology, and distribution of species are given.

    Revision of the subgenus Mesopraocis Flores & Pizarro-Araya of the Neotropical genus Praocis Eschscholtz (Coleoptera, Tenebrionidae, Pimeliinae)
    The second part of a revision of the species of the genus Praocis Eschscholtz is presented. The subgenus Mesopraocis Flores & Pizarro-Araya, distributed in northern Chile from 25° South to 31° South, is revised. This article includes a redescription of the subgenus, redescriptions of its species, an identification key, and a discussion on morphological adaptations of the species to fossorial life. Habitus photographs, scanning electron micrographs of head, antennae, prosternum, abdomen, and protibiae, illustrations of genital features, and distribution maps are presented. Conical pegs sensilla on tibiae are described and illustrated using SEM for the first time for a South American tenebrionid species. A new Praocis species is described: Praocis (Mesopraocis) arenicola sp. nov. Praocis (Mesopraocis) flava Kulzer, 1958 is synonymised with P. (M.) pilula Laporte, 1840. Other species of the subgenus are: P. (M.) calderana Kulzer and P. (M.) nitens Kulzer. A statement on the variation in the number of antennomeres in P. (M.) pilula is appended.
