First record of the beekeeping pest Aethina tumida Murray (Coleoptera: Nitidulidae) for Honduras
(2024)
Aethina tumida Murray (Coleoptera: Nitidulidae) (also known as the small hive beetle), an important pest in apiaries, is reported from Honduras for the first time, new country record. The precise distribution in the country is unknown, and no damage related to it has been observed. Photographs are provided to aid in its identification. Differentiation of A. tumida from Aethina villosa Reitter and Aethina quadrata Sharp, which also occur in Honduras, is provided.

The chenopodium aphid, Hayhurstia atriplicis (Linnaeus, 1761) (Hemiptera: Aphididae), is reported for the first time in Colombia. The aphid was found on the aerial parts of the quinoa plant, Chenopodium quinoa Willd. (Amaranthaceae), especially on the leaves, in five municipalities in the department of Cauca, Colombia. Brief information on its natural enemies, distribution and biology is provided. This is the only aphid in Colombia known to cause malformations on the leaves of quinoa plants. In South America, this aphid has been found previously only in Ecuador, where it was reported for the first time in 2023 based on specimens collected from 2019 to 2021. However, we report that H. atriplicis was likely introduced to Ecuador in the 2000s or earlier, based on a collection dated 2006 found in the United States National Museum of Natural History.

Three species of false click beetles (Coleoptera: Eucnemidae) are added to the Nearctic fauna. One new species, Isorhipis bicolor, is described from a small series collected in Florida, U.S.A. Eighteen specimens collected from Georgia were identified as Dyscharachthis amplicollis (Fleutiaux), new U.S.A. records for a species previously taken from Japan and Southeast Asia. Examination of a series of eucnemids collected by Kyle Schnepp in Florida allowed me to revisit the Deltometopus fauna in eastern North America. Antennal structures present in a series of male specimens in the loan and past examined specimens are definitive enough to resurrect Deltometopus ereptus Bonvouloir, status restored, from synonymy with Deltometopus amoenicornis (Say). Species identification keys are provided for Deltometopus Bonvouloir and Isorhipis Boisduval and Lacordaire in the Nearctic region. Diagnostic differences are briefly noted for each of the three newly added species found in the United States. Images of three species and the related D. amoenicornis are provided.

An overview of the genus Psephenops Grouvelle (Coleoptera: Psephenidae: Psepheninae) is provided with geographic distributions of the species. The taxonomic history of Psephenops smithi Grouvelle, the type species from Grenada and St. Vincent, and junior synonym Xexanchorinus latus Grouvelle from Grenada, is discussed, and lectotypes and paralectotypes are designated for both. Photographs of the type series and a non-type specimen with illustrated male genitalia, along with new distributional information for the species, are provided. The male, female, and associated larva of Psephenops trini Barr and Shepard, new species, are described and illustrated, as is the habitat of this species in Trinidad and Tobago. The Peruvian species Psephenus robacki Spangler is transferred from Psephenus Haldeman to Psephenops as Psephenops robacki (Spangler) new combination. Photographs of the female holotype are included, and possible new distributional records from Peru are reported.

Pears, Pyrus pyrifolia (Burm.f.) Nak. (Rosaceae) are one of the most widely grown fruit trees in South Korea. Approximately 11% of the total pear production in 2022 was exported to countries such as the US and Vietnam. Exported pears must be free of pest species that are considered of quarantine importance by the importing countries. Herein, a list of scale insects (Hemiptera: Coccomorpha) associated with pear trees is updated. Additionally, Spilococcus pacificus (Borchsenius) is added to the list of mealybugs affecting pears in South Korea and is briefly diagnosed based on non-type specimens and illustrated using photographs. Information on its distribution and plant hosts are also provided.

The beetle genus Pharaxonotha Reitter (Coleoptera: Erotylidae: Pharaxonothinae) is found in the cones of cycad genera in the New World, including species of Ceratozamia Brongn., Dioon Lindl., Microcycas (Miq.) A.DC and Zamia L. Its presence and diversity are analyzed for the 17 species of Zamia known to occur in Panama. Nine species are recognized, and five new species are described: Pharaxonotha clarkorum Pakaluk, P. confusa Pakaluk, P. fortunensis Tang, Skelley and Taylor new species, P. holzmani Tang, Skelley and Taylor new species, P. kirschii Reitter, P. manicatae Tang, Skelley and Taylor new species, P. panamensis Tang, Skelley and Taylor new species, P. pseudoparasitica Tang, Skelley and Taylor new species, and P. taylori Skelley and Tang. A key to species of Pharaxonotha in Panama is presented.

A new species, Chlorocoris charluzae Thomas (Hemiptera: Heteroptera: Pentatomidae), is described from Panama. Eludocoris grandis Thomas is reported from Panama for the first time. The distribution of Chlorocoris rufispinus Dallas to include Panama is confirmed. Arawacoris Thomas, described as a subgenus of Chlorocoris Spinola, is elevated to full genus.

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.

Pseudococcus longispinus (Targioni-Tozzetti) (Hemiptera: Pseudococcidae) is a widely-distributed pest that feeds on many economically important hosts, particularly tropical fruits and ornamentals. The potential distribution of this mealybug pest in South Korea remains a primary concern because of its high incidence of interceptions screened during inspection. Hence, this species prompted a modelling effort to assess its potential risk of introduction. Potential risk maps were developed for this pest with a CLIMEX model based on occurrence records under environmental data. The potential distribution of these pests in South Korea in the 2020s, 2050s and 2090s was projected based on the RCP 8.5 climate change scenario. Results showed that P. longispinus has little potential for invasion in the outdoor environment of South Korea due to high cold stress in the 2020s. However, some locations in Jejudo were predicted to be marginally suitable under future climate factors. In that respect, the results of this model prediction could be used to prepare a risk-based surveying program that improves the probability of detecting early P. longispinus populations.
