A survey of Bariditae in Mississippi resulted in 75 species in 32 genera and included two undescribed species and 36 new state records. An additional two species were recognized as possibly occurring in Mississippi. Diagnoses for all of the genera and species in the state are provided, and keys to the genera as well as all of the species were made. Species were found in every county within Mississippi and are representative of the Bariditae fauna of the southeastern United States. Open, prairie-like habitats and aquatic wetlands were the habitats with the highest biodiversity of Bariditae in the state. Species of Baris, Geraeus, Linogeraeus, and Odontocorynus were found in the highest numbers, and Linogeraeus and Sibariops were found to be the most speciose genera in the state. Sibariops amica, S. benigna, and S. houstoni, are proposed as new synonyms of S. concinna. New state records are included for Mississippi as well as Alabama, Arkansas, Kentucky, Louisisna, Maryland, Missouri, North Caolina, and Tennessee.

The aim of this study is understanding faunistic and zoogeographical composition of the Turkish Buprestidae fauna and determining similarities between Turkey and its adjacent countries. Palaearctic region is handled in nine subregions (Southern Europe, Western Europe, Northern Europe, Eastern Europe, Siberia, Middle East, Middle Asia, Far Eastern Asian and North Africa). Buprestidae fauna of Turkey has 421 species belonging 37 genera and 6 subfamilies according to present literature. Chrysochroinae (130 species) and Buprestinae (132 species) are the most specios subfamilies in Turkey. The genera Anthaxia (103 species) and Sphenoptera (82 species) were the most species-rich genera. The fauna of Greece have highest of similarity with Buprestidae fauna of Turkey. Acmaeoderella flavofasciata (Piller and Mitterpacher, 1783), Capnodis cariosa (Pallas, 1776), Capnodis porosa (Klug, 1829), Capnodis tenebricosa (Olivier, 1790), Capnodis tenebrionis (Linnaeus, 1761), Anthaxia anatolica Chevrolat, 1838, Chrysobothris affinis (Fabricius, 1794), Melanophila cuspidata (Klug, 1829), Trachypteris picta (Pallas, 1773), Coraebus rubi (Linnaeus, 1767) and Meliboeus parvulus Küster, 1852 are existing in Turkey and all adjacent countries.

Gnamptogenys triangularis (Mayr) is a predatory ant that feeds primarily on millipedes. This species has an enormous native range in South and Central America that extends from subtropical Argentina (38.1°S) to tropical Costa Rica (10.4°N). The earliest known records of G. triangularis outside its native range were from Florida beginning in 1985, with subsequent published records from Alabama (1996–) and Mississippi (2002–). Here, we present new records of G. triangularis documenting further expansion of populations in the southeastern US, including first published site records from Texas (2013–), Louisiana (2019–), and South Carolina (2019–). In the southeastern US, G. triangularis occurs in a wide range of habitats, from relatively intact forest to highly disturbed urban sites. Its northernmost site records are from South Carolina (34.1°N), but based on its South American range, G. triangularis may have the potential to spread further north. Gnamptogenys triangularis readily consumes the greenhouse millipede, Oxidus gracilis (Koch), a cosmopolitan species originally from Asia, which is now very common in disturbed environments of the southeastern US, so potential prey for G. triangularis may be plentiful throughout this region.

We present an annotated list of 22 species of blow flies (Diptera: Calliphoridae) and one species of cluster flies (Polleniidae) known from the state of Mississippi, with one additional blow fly species likely to occur there based on a record in neighboring Alabama. New state records include five species from the subfamily Calliphorinae: Angioneura flavescens (Reinhard), Angioneura obscura (Townsend), Opsodexia bicolor (Coquillett), and Opsodexia nox (Downes), and Lucilia eximia (Wiedemann). The number and density of taxa per 100,000 km² is consistent with that of blow fly taxa recorded for other states across the contiguous United States.
