The Strongylophthalmyia ustulata group (Diptera: Brachycera: Strongylophthalmyiidae) from China is revised. Five species are recognized, including three new species (S. elongata sp. nov., S. flavimarginata sp. nov., and S. sivelli sp. nov.) and one new record species [S. ustulata (Zetterstedt, 1847)]. Strongylophthalmyia yaoshana Yang & Wang, 1998, previously placed in the S. ustulata group, is herein transferred to the S. fascipennis group based on its bare antennal arista and patterned wing. A key to the Chinese species of the S. ustulata group is provided.

A redescription of the genus Aldrichiopa Aldrich, 1934 (Diptera: Tachinidae) is provided and a new species, Aldrichiopa serrata Torres-Domnguez & Mulieri sp. nov. is described from specimens collected in Argentina and Chile. A detailed morphological description of the egg, first instar larva, and adult male and female including terminalia are presented for the first time. Exhaustive photographic records, scanning electron microscopy images, morphological detail of antennal ultrastructure, and updated geographic distributions are provided for the two species of the genus, Aldrichiopa coracella (Aldrich) and A. serrata sp. nov. An identification key based on males is provided. The taxonomic placement of Aldrichiopa to subfamily and tribe is discussed and information on the hosts of this genus of small tachinid flies is compiled.

A new record of the rare species Mirocastnia pyrrhopygoides (Houlbert) from Ecuador is reported, along with range extensions for M. smalli (J. Y. Miller) and M. canis (Lathy). In addition, the genus Mirocastnia J. Y. Miller is revised and the diagnostic phenotypic characteristics of males and females, as well as male genitalia, are illustrated. Details on its natural history, biogeography, and biology are included with the purpose of solving the confusion in the taxonomy of the genus. All taxa previously considered to be species are herein relegated to subspecific status, i.e. M. pyrrhopygoides canis stat. nov. and M. p. smalli stat. nov.

The taxonomy of the crickets from the genus Odontogryllodes Chopard, 1969 is reviewed. Two species new to science are described here, one from Peninsular Malaysia (part of Malay Peninsula) and another from East Malaysia (part of Borneo): Odontogryllodes undatus Tan, Muhammad & Abdullah sp. nov. from Panti Forest Reserve and Odontogryllodes magnus Tan, Japir & Chung sp. nov. from Tenompok Forest Reserve, respectively. We also present an updated key to the species of Odontogryllodes. In total, nine species are currently known.

The southern African genus Antoniejanse Kemal & Koak, 2005 is revised. Seven species are recognized here as valid, of which four species are described as new for science from South Africa (A. varii sp. nov. and A. tenebrosa sp. nov.) and Namibia (A. minima sp. nov. and A. mediopunctata sp. nov.). One new combination is proposed: Antoniejanse sagittata (Bidzilya, 2019) comb. nov. (ex Paratelphusa). All species of Antoniejanse are re-diagnosed. Wing patterns, as well as male and female genitalia are depicted. An identification key to all species of the genus is provided and the checklist of the genus is updated.

Three Asian longhorned ticks (Haemaphysalis longicornis) were collected on Staten Island, Richmond County, New York, in 2014-2015 as part of a tick-borne disease surveillance program conducted by the New York City Department of Health and Mental Hygiene and the Defense Centers of Public Health - Aberdeen Tick-Borne Disease Laboratory. These records mark the earliest known occurrence of H. longicornis in New York State outside of quarantine areas, predating previously reported detections by several years. Robust populations of H. longicornis were collected in subsequent years at the Staten Island site where these few ticks were found, demonstrating that small infestations have the potential to proliferate quickly. Haemaphysalis longicornis is a 3-host ixodid tick native to eastern Asia but now established in the United States, as well as Australasia and several Pacific islands. Although H. longicornis has not yet been associated with human disease transmission in the United States, it warrants attention as a potential vector, as it is demonstrated to harbor various pathogens of medical and veterinary interest across its native and introduced range.

A review of the subgenus Mesolethrus Nikolajev, 2003, with diagnostic characters, distribution data and a key to the species is provided. Lethrus (Mesolethrus) dyonini A. Shapovalov & Bagaturov, new species, is described from Uzbekistan (Tashkent Region). Lethrus (Mesolethrus) shakhristanicus Nikolajev, 2003 is recorded for the first time from Kyrgyzstan and Uzbekistan. Previous records of L. (M.) inermis Reitter, 1866 from Kyrgyzstan are considered erroneous.

Agenamyia Albuquerque, an endemic neotropical genus with two species, has been revised to include three new species: Agenamyia colombiana de Carvalho, Wolff & Fogaa sp. nov. from Envigado; Agenamyia maculata de Carvalho, Wolff & Fogaa sp. nov. from El Retiro; and Agenamyia timida de Carvalho, Wolff & Fogaa sp. nov. from Sopetrn, all localities in Antioquia, Colombia. This review presents an identification key for all species, including color images and illustrations of male and female terminalia. The distribution of all species is mapped and discussed.

The genus Ashibusa Matsumura, 1931 is reviewed from China. Eight new species are described: A. apicodonta Li, sp. nov., A. biniprocessa Li, sp. nov., A. dilatirotunda Li, sp. nov., A. improjecta Li, sp. nov., A. ledongensis Li, sp. nov., A. longispina Li, sp. nov., A. similativalvula Li, sp. nov. and A. subfalcativalva Li, sp. nov. The females of A. flavalba Zhang & Li, 2009 and A. lativalvula Zhang & Li, 2009 are described for the first time. Images of adults and genitalia are provided for the new species and for the newly described female genitalia. A key to all the species and a map showing the distribution of these species are provided.

The spider genus Echinax Deeleman-Reinhold, 2001 is reviewed in China. Two new species, E. breviducta sp. nov. () and E. wuzhishan sp. nov. (), are described and illustrated. The female of E. baisha Lu & Li, 2023 is reported for the first time, and three known species, E. anlongensis Yang, Song & Zhu, 2004, E. oxyopoides (Deeleman-Reinhold, 1995) and E. panache Deeleman-Reinhold, 2001, are illustrated.
