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.

The present study is based upon soldier flies (Diptera: Stratiomyidae) collected from Turkey between 1996 and 2007. A total of 21 species in seven genera belonging to the subfamilies Hermetiinae, Sarginae, Stratiomyinae, and Nemotelinae are presented, with the first records of Exochostoma ornatum Lindner, 1974, Odontomyia annulata (Meigen, 1822), Stratiomys singularior (Harris, 1778), and Nemotelus aerosus Gimmerthal, 1847 for the Turkish fauna. New distribution records for previously reported species are given. Photographs of the species are provided, and a zoogeography characterization for each species is discussed.

Two new species of the genus Kubaniellus Kalashian, 1997 are described and illustrated, both from China: Kubaniellus kalashiani sp. nov., from Guangdong Province and K. daguishancola sp. nov. from Guangxi Zhuang Autonomous Region.

Eulophid larvae discovered in galleries of Agrilus cuprescens (Ménétries, 1832) within canes of Rubus sp. (Rosaceae) in the Pacific Northwest, U.S.A. region between 2018 and 2021 were identified as Baryscapus rugglesi (Rohwer, 1919) (subfamily Tetrastichinae). This species had previously only been found in eastern North America. Identification was based on numerous specimens reared from larvae collected from eight disparate locations in western Oregon and Washington State, U.S.A., in 2019 and 2021, and examination against its type series from 1919 in Minnesota, U.S.A. and specimens from 1938 in New York, U.S.A (Mundinger 1941). Both sexes of B. rugglesi are herein redescribed and illustrated. Additionally, DNA sequences from specimens collected in 2019 were direct sequence matches with original specimens collected in 2018. The ubiquitous occurrence of B. rugglesi suggests it is likely a predominant parasitoid of A. cuprescens in the region. Baryscapus rugglesi is a gregarious larval parasitoid of several native Agrilus spp. in North America, so it is presumably native to the Nearctic region and has adapted as an alternative parasitoid of A. cuprescens, a Eurasian-native pest introduced into North America. However, COI sequences of B. rugglesi were similar to those of an unidentified eulophid from Europe in the Barcode of Life Database (almost 96% identity), possibly indicating a Holarctic distribution. Observed wasp biology, behavior, and perspectives on the potential role of B. rugglesi as a natural enemy within integrated pest management programs for A. cuprescens control are discussed.

Several species of lady(bird) beetles have been purposefully and inadvertently introduced for more than 100 years in the Hawaiian Archipelago. Here, we report new state records for two lady beetle species in Hawai‘i, 20 new island records associated with 14 lady beetle species, and prey information associated with eight records. The update includes new geographic distribution records from five of the eight main islands and the Northwestern Islands of the Hawaiian Archipelago. New state records are reported for Delphastus pallidus LeConte, 1878 and Novius pumilus (Weise, 1892) in Hawai‘i. New island records are reported for Brumoides suturalis (Fabricius, 1798); Cycloneda sanguinea sanguinea Linnaeus, 1763; Diomus roseicollis (Mulsant, 1853); Hyperaspis connectens (Thunberg, 1808); Hyperaspis silvestrii Weise, 1909; Nephaspis bicolor Gordon, 1982; Nephus roepkei (Fluiter, 1938); Psyllobora vigintimaculata (Say, 1824); Rhyzobius lophanthae (Blaisdell, 1892); Scymnobius bilucernarius (Mulsant, 1850); Scymnus (Pullus) latemaculatus Motschulsky, 1858; Serangium maculigerum Blackburn, 1892; an undetermined Pharoscymnus sp. previously recorded in Hawai‘i; and an undetermined Sticholotis sp. previously reported from Hawai‘i. We report Laos as a new country record for the Sticholotis sp. Prey records are documented in Hawai‘i that include Tetraleurodes acaciae (Quaintance, 1900) for D. pallidus; Aleurodicus dispersus Russell, 1965 for S. maculigerum; Bemisia argentifolii Bellows & Perring 1994 and Metaleurodicus cardini (Back, 1912) for N. bicolor; Aleurotrachelus trachoides (Back, 1912) for N. indus and D. roseicollis; Aonidiella orientalis for R. lophanthae; and Aphis nerii Boyer de Fonscolombe, 1841 for S. latemaculatus. The new records demonstrate the value of ongoing sampling and regular examination of undetermined collections.
