A male Diachasma muliebre (Musebeck, 1956) (Hymenoptera: Braconidae), an historically reported monophagous, thelytokous parasitoid, was reared from Rhagoletis indifferens Curran, 1932 (Diptera: Tephritidae) puparia. The fly larvae were reared from Prunus emarginata (Douglas ex Hooker) Eaton (Rosaceae) fruit collected in Placer County, California in 2022. An examination of D. muliebre specimens in California collections found four additional males in the California State Collection of Arthropods, the Bohart Museum of Entomology, and the Essig Museum of Entomology. The males were collected over a 60-year period from 1962 to 2022 in Nevada, Placer and Siskiyou Counties some 272 air km apart in northern California. Possible mechanisms explaining the predominately asexual reproduction in D. muliebre and the periodic presence of males are proposed.

This study investigates the diversity, abundance, and composition spider communities in Rancho Las Playitas, Arizpe and Bacoachi, Sonora, Mexico. Moreover, we present a comprehensive species list for the Sky Island Mountains of Sonora, compiled from recent surveys. Spiders were collected using three methods: visual searching, foliage beating, and pitfall trapping. We report 29 new distributional records for spider species, four of which are new country records for Mexico and 25 for the state of Sonora. Additionally, we describe and image the vulva of Calilena arizonica Chamberlin & Ivie, 1941 for the first time, and provide images of 28 additional species. Our findings expand the known spider diversity in the region and reveal richness and compositional pattern in Rancho Las Playitas that exhibit low similarity to other spider communities from arid environments.

Estudiamos la diversidad, abundancia y composición de una comunidad de arañas en Rancho Las Playitas, Arizpe y Bacoachi, Sonora México. Además, se compiló una lista de arañas de las Islas Serranas (Archipiélago Madrense) de Sonora con base en colectas recientes. Las arañas se colectaron mediante tres métodos: búsqueda visual, golpeo en la vegetación y trampas de caída. Además, proporcionamos nuevos datos de distribución de 29 especies de arañas, de las cuales cuatro especies se registran por primera vez para México y 25 para el estado de Sonora. Adicionalmente, describimos e ilustramos la vulva de Calilena arizonica Chamberlin & Ivie, 1941 y proveemos imágenes de 28 especies adicionales. Nuestros resultados son una contribución al conocimiento de la diversidad de arañas en esta región y demuestra que los patrones de riqueza y composición en Las Playitas presentan una baja similitud en comparación con otras comunidades de las zonas áridas.

Clarifying comments are provided for several previously published records from North America, including the Palearctic species Agrilus integerrimus (Ratzeburg, 1837) and Buprestis (Ancylocheira) hameorrhoidalis Herbst, 1780, which are considered erroneous and are excluded from the North American fauna.

Since its introduction into Seattle, King County, Washington, prior to 1952, the European thomisid Ozyptila praticola (C. L. Koch, 1837) has spread throughout the eastern Puget Lowlands to inhabit an area of over 1300 sq mi (3400 sq km) centered in western King and Snohomish Counties. A separate population of O. praticola was also found in western Whatcom Co. that may be linked to the O. praticola population in Metro Vancouver, British Columbia, Canada. Ozyptila praticola was eudominant (> 10% abundance) in 86% of fallen conifer cone, 69% of moss, and 55% of litter samples. It was largely found in anthropogenically disturbed habitats, with some invasion into forests adjacent to development. Females, penultimates, and a consistent size-range of pre-penultimate juveniles were present year-round. Males were found mainly in spring and fall. Ozyptila praticola may be expected to continue increasing its range in anthropogenic and adjacent habitats in western Washington.

The morphology of head of the genus Coraebus Gory et Laporte, 1839 is introduced and discussed. Two new species from China are described and illustrated: Coraebus iridicollis, sp. nov. and Coraebus xiapu sp. nov.
