New World species of the histerid beetle genus Xestipyge Marseul (Coleoptera: Histeridae: Dendrophilinae: Paromalini) are reviewed, and X. skelleyi, new species, is described. A dichotomous key and illustrations are provided as identification means for the now five included species from the Western Hemisphere.

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.

A new genus and new species of Onciderini Thomson, 1860 (Coleoptera: Cerambycidae: Lamiinae) are described and illustrated: Velozideres buntyni, from Ecuador. The following two new synonymies in Onciderini are proposed: Oncideres paurosoma Noguera, 1993 = Microcanus minor (Bates, 1885); Oncioderes piauiensis Martins and Galileo, 2013 = Oncioderes rondoniae Martins and Galileo, 1990. The following seven new country records are reported: Clavidesmus chicae Giorgi, 1998 (Onciderini) (Argentina); Ecthoea quadricornis (Olivier, 1795) (Onciderini) (Venezuela); Oncideres ophthalmalis Dillon and Dillon, 1946 (Onciderini) (Costa Rica); Oncideres punctata Dillon and Dillon, 1946 (Onciderini) (El Salvador); Oncideres xavieri Galileo and Martins, 2010 (Onciderini) (Peru); Trestonia signifera Buquet, 1859 (Onciderini) (Brazil); and Oideterus crenatocerus (Galileo, 1987) (Cerambycidae: Prioninae: Anacolini) (Costa Rica).

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.

We also report a second record of P. alexanderi Wirth from Veracruz, Mexico. A key to the known species in Mexico is included.

New records for a new species and other exotic Dirrhagofarsus Fleutiaux (Coleoptera: Eucnemidae: Melasinae: Dirhagini) species are reported from throughout much of the northeastern and southern areas of the United States. Dirrhagofarsus brevis, new species, is hereby described in this study. Two other exotic species, Dirrhagofarsus modestus (Fleutiaux) and Dirrhagofarsus unicolor (Hisamatsu), new country records, are redescribed and diagnosed as they were compared with other Dirrhagofarsus species present in the Nearctic region. All Dirrhagofarsus species in this study are imaged, highlighting essential character states to facilitate better diagnosis in conjunction to the new identification key provided in this study.

Fractipes tayrona new species (Coleoptera: Chrysomelidae: Eumolpinae: Eumolpini) is described from a dry forest on the Caribbean coast of Colombia. This locality is very distant from the localities in southeast Brazil, where the other two known species of Fractipes Bechynĕ were described. Male and female genitalia are described for the first time in this genus, and F. tayrona is compared with holotype photographs of F. rhabdopteroides Bechynĕ and F. secundus Bechynĕ and Springlová de Bechynĕ.
