Acmaeodera daveverityi, sp. nov., is described from Colima, Mexico, and a habitus image is provided.

Chrysobothris daveverityi sp. nov. from Guerrero, Morelos, Michoacán, Oaxaca, and Puebla in southwestern Mexico is described and illustrated. The species has been confused with C. acutipennis Chevrolat, 1835 and C. merkelii Horn, 1886, from both of which it can be distinguished by color, surface sculpture, and male genitalia. The new species is diagnosed, figures of dorsal habitus and male genitalia for the three species are provided, and comments are made regarding their relationship and distribution, including three new state records and one new adult host plant record. The new species is named to honor the late David Verity in recognition of his contributions to the knowledge of Buprestidae.

Chrysobothris daveverity sp. nov. de Guerrero, Morelos, Michoacán, Oaxaca, y Puebla en el suroeste de México se describe e ilustra. La especie se ha confudido con C. acutipennis Chevrolat, 1835 y C. merkelii Horn, 1886, de los cuales se puede distinguir por el color, la escultura superficial, y los genitales masculinos. Se diagnostica la nueva especie, y se proporcionan figuras de habitus dorsal y genitales masculinos para las tres especies, y se hacen comentarios con respecto a su relación y distribución, incluyendo tres nuevos registros estatales y un nuevo registro de planta huésped adulta. La nueva especie lleva el nombre en honor al difunto David Verity en reconocimiento a sus contribuciones al conocimiento de Buprestidae.

Cafius chilensis sp. nov. is described from the Chilean coast. Adults of the new species were collected under seaweed and are similar to those of C. algophilus Broun, 1894 and C. maritimus (Broun, 1880) from the New Zealand coast. Morphological comparison for these three species is presented. A description, SEM and habitus photographs, and illustrations of diagnostic characters of the new species are provided to facilitate identification.

A total of 5183 adult aquatic insects, representing 3 orders, 7 families, and 16 genera, and 1447 adult terrestrial insects representing 8 orders and 21 families, were light trapped at Lake Murray Reservoir, San Diego County, California, from 17 April–25 November 2019. Diptera was the most abundant taxon for all sampled individuals. A single species of mayfly, Caenis amica Hagen, 1861, was collected. Five aquatic Diptera and three Trichoptera species are new distribution records for San Diego County. A second state distribution record for the micro-caddisfly, Oxyethira arizona Ross, 1948, is also reported. New observations of adult swarming behavior of the caddisfly, Oecetis inconspicua (Walker, 1852), are reported.

The bow-legged bug genus Hyalymenus Amyot & Serville, 1843 (Hemiptera: Heteroptera: Coreoidea: Alydidae) includes 20 New World species. Of these, nymphs of only one species, H. tarsatus (Fabricius, 1803), have been described, and the description was restricted to the fifth instar. Nine specimens of H. subinermis Van Duzee, 1923, representing the first through the fifth instars, were collected on two Schinus terebinthifolia Raddi (Anacardiaceae) shrubs from a residential neighborhood (approximately 177,828 m² surveyed) in Long Beach, California, U.S.A. in June 2021. Several other locations within the city were surveyed (i.e., parks, residential areas, and riparian habitats; approximately 109,177 m² surveyed, collectively), but this species was not observed on other S. terebinthifolia plants or other plant species in these areas. Here, we give the first California record for H. subinermis, describe the five nymphal instars, provide habitus images of each instar, and discuss the distribution of the species in California, known host plants, and putative ant models that nymphs may mimic.

The Euxesta sororcula species group, which contains several pests of corn, is reviewed based on study of type and newly collected specimens. A new synonymy is proposed: Euxesta obliquestriata Hendel, 1909 = Euxesta mazorca Steyskal, 1974, syn. nov. Euxesta sororcula (Wiedemann, 1830), previously known from South and Central America as a pest of sweet corn, is here reported for the first time in the United States, in the state of Texas. Illustrations of and a key to the species of the E. sororcula species group are provided.
