Abstract. New state records for 35 species of Eucnemidae (Coleoptera: Elateroidea) are reported from the eastern United States based on examination and identification of specimens from several institutional and two private collections in the last year. Images of 18 eucnemid species are provided.

Members of the genus Centris Fabricius (Hymenoptera: Apoidea: Anthophila) constitute a significant component of the Neotropical (including insular) bee fauna, exhibiting high species richness, a moderate to large body size, and extensive interactions with various important plant groups. Females of most species possess specialized morphology adapted for collecting oils from flowers. This study documents the presence of the genus in Cuba, recognizing six species: C. aethiops Cresson, C. cornuta Cresson, C. fulviventris Cresson, C. poecila Lepeletier, C. taina Genaro and Breto new species, and C. tarsata F. Smith. Detailed information is provided for each species, encompassing a diagnosis, natural history, floral associations, seasonal occurrence, and distribution. Centris taina new species is described from Cuba, based on both sexes, which were previously misidentified as C. versicolor (Fabr.) for females and C. fasciatus F. Smith for males due to sexual dimorphism. Centris tarsata is reported as a new national record for Cuba, possibly introduced by humans from South America and now established and widely distributed across the entire island. A key to differentiate the Cuban species of Centris is presented.

A checklist of the dung beetles (Coleoptera: Geotrupidae; Scarabaeidae: Aphodiinae and Scarabaeinae) of Oaxaca, Mexico, is presented for the first time. The checklist contains 252 taxa, 15 Geotrupidae, 77 Aphodiinae, and 160 Scarabaeinae. The state includes 58 genera and 15 tribes, where Onthophagus is the most species-rich genus with 49 taxa, followed by Ataenius with 22, Canthon with 17 and Phanaeus with 15 taxa. Valid names, as well as synonyms, are provided. First records, notes on presently recognized species, nomenclatural problems, and biodiversity comparisons are included. Phanaeus dionysius Kohlmann, Arriaga-Jiménez and Rös, 2018 (Coleoptera: Scarabaeidae: Scarabaeinae) is re-established as a valid species.

We describe and illustrate a new Neotropical predaceous midge, Parabezzia carlae Huerta, Spinelli and Grogan, new species (Diptera: Ceratopogonidae) from males collected by Malaise trap in La Union, Ayutla de los Libres, state of Guerrero, Mexico. We also report a second record of P. alexanderi Wirth from Veracruz, Mexico. A key to the known species in Mexico is included.
There are 214 species of the suborder Tipulomorpha (Diptera) known from Panama. Of these, 162 species were described by the noted American entomologist, Charles Paul Alexander, from Panama during the period from 1912 through 1979. Panama hosts two of the four families found within the Tipulomorpha: Limoniidae (197 species) and Tipulidae (17 species). We have records of only three species from multiple provinces (n = 2) within Panama and 211 species from just one province. The vast majority of the latter are known from a single location within their respective provinces. There are 142 endemic species (66.4%) included in Panama’s Tipulomorpha fauna, with the remainder being found elsewhere in South America (48 species), Central America (44), Mexico (23 species), the Caribbean (14 species), and the United States (4 species). Whereas, this taxonomic group has benefited from collecting in the Canal Zone and the popular western highlands in Chiriqui Province, we know little or nothing of the distribution of species within the country, their natural history, or their relationship to water quality.
Seventy-nine Cerambycidae and two Vesperidae species not previously recorded from Bolivia are listed along with the department where they were collected, and are thus added to the known fauna. An additional 22 species from existing publications, but whose Bolivian distribution is not recorded in the 2013 version of Bezark and Monné (2013), are listed separately to assist inclusion in this important reference. These records, along with the 60 new species described (through February, 2013) since Wappes et al. (2011), brings the total number of Cerambycidae and, closely related families Disteniidae, Oxypeltidae and Vesperidae, to 1,717 species known from Bolivia. New departmental records for another 254 species are listed. Color illustrations for 80 of the 81 species newly recorded from Bolivia are provided. Among the new records for Bolivia is Lathroeus oreoderoides Thomson, 1864 previously known only from South America without exact locality, hence this is its first recorded distribution. A male of Myzomorphus Dejean, 1835 collected at the same time and locality as a female Myzomorphus amabilis (Tippmann, 1960) is likely the previously unknown male of the species. Both sexes are illustrated.
