A new genus and sixteen new species of false click beetles (Coleoptera: Eucnemidae) described from the Heredia Province of Costa Rica with several additional records from the Osa Peninsula and Panama
- Abstract. More than 1300 specimens of Eucnemidae collected from Heredia Province in Costa Rica during the 1990s Arthropods of La Selva (ALAS) survey were studied from 2018 through 2022. One new genus of false click beetle, Absensiugum Otto, Muona and Córdoba-Alfaro, is described. Nematodes teres Horn, from the Nearctic and Caribbean regions, is transferred to this new genus to form Absensiugum teres, new combination. Sixteen new species of false click beetle (Coleoptera: Eucnemidae) are described from Costa Rica. These new species are: Adelothyreus brevis, Adelothyreus costaricensis, Adelothyreus totus, Quirsfeldia stethonoides, Lacus pectinatus, Maelodrus costaricensis, Onichodon confluentus, Onichodon rufus, Isarthrus striatus, Absensiugum brunneum, Dromaeolus americanus, Dromaeolus brunneus, Dromaeolus herediensis, Dromaeolus holdridgei, Deltometopus bicolor and Nematodes apicalis. Three additional records outside of the Heredia Province from the Osa Peninsula and Panama for Lacus pectinatus are included in this study. Identification keys are provided for species of Adelothyreus Chevrolat, Onichodon Newman, Dromaeolus Kiesenwetter, Deltometopus Bonvouloir and Nematodes Berthold in Costa Rica. Diagnostic differences are briefly noted for each species within the Neotropical region. A list of Eucnemidae from Heredia Province is provided. ZooBank registration. urn:lsid:zoobank.org:pub:C1D5B819-A964-4679-B090-84CDBBC59D6A
- Se estudiaron más de 1300 especímenes de Eucnemidae recolectados de la provincia de Heredia en Costa Rica durante la encuesta de Artrópodos de La Selva (ALAS) de la década de 1990 desde 2018 hasta 2021. Se describe un nuevo género de escarabajo de falso clic, Absensiugum Otto, Muona y Córdoba-Alfaro. Nematodes teres Horn, de las regiones Neártica y Caribe, se transfiere a este nuevo género para formar Absensiugum teres, nueva combinación. Se describen dieciséis nuevas especies de escarabajos de falso clic (Coleoptera: Eucnemidae) de Costa Rica. Estas nuevas especies son: Adelothyreus brevis, Adelothyreus costaricensis, Adelothyreus totus, Quirsfeldia stethonoides, Lacus pectinatus, Maelodrus costaricensis, Onichodon confluentus, Onichodon rufus, Isarthrus striatus, Absensiugum brunneum, Dromaeolus americanus, Dromaeolus brunneus, Dromaeolus herediensis, Dromaeolus holdridgei, Deltometopus bicolor and Nematodes apicalis. En este estudio se incluyen tres registros adicionales fuera de la Provincia de Heredia de la Península de Osa y Panamá para Lacus pectinatus. Se proporcionan claves de identificación para especies de Adelothyreus Chevrolat, Onichodon Newman, Dromaeolus Kiesenwetter, Deltometopus Bonvouloir and Nematodes Berthold en Costa Rica. Las diferencias de diagnóstico se observan brevemente para cada especie dentro de la región neotropical. Se proporciona una lista de verificación de Eucnemidae de la provincia de Heredia.
