This is a progress paper on the taxonomy of eleven genera in the grasshopper family Lentulidae from South Africa. They are: Afrotettix Dirsh with eight species, six of which are new (abuntix, berupo, eduva, tinipa, frixo and rabex); Calviniacris Dirsh with one species; Atopotattix Brown with one species; Devylderia Sjostedt, with eleven species, seven of which are new (locapsa, lishe, compoti, seche, segasa, solveigae, and koenigkrameri); Karruia Rehn with three species, one of which is new (nova); Dirshidium Brown with three species, two of which are new (kado and jati); Gymnidium Karsch, with three species, one of which is new (ydiumi); Leatettix Dirsh with 18 species, eleven of which are new (carinae, lillianae, erymnita, fursti, elizabethae, cowperi, greeni, knowlesi, armstrongi, cadei and rohweri); Tsautettix Otte, with one new species (adriani); Kalaharicus Brown, with one species; and Shelfordites Karny with five species, three of which are new (lapollai, laurelae, and spearmani).

The fauna of Iranian Dytiscidae (Coleoptera) is reviewed listing all hitherto known distribution records. Comments on taxonomy, identification and nomenclature are provided. The type locality is also given for each species originally described from Iran. One species, Rhantus (Rhantus) frontalis (Marsham, 1802) is new for the fauna of Iran. According to the literature and the new record, 140 dytiscid taxa representing 32 genera are at present known from Iran. Four species, Deronectes sahlbergi Zimmermann, 1932, Hydroporus nigrita (Fabricius, 1792), Hygrotus (Hygrotus) versicolor (Schaller, 1783), and Nebrioporus insignis (Klug, 1834) are doubtful. Five taxa, Agabus (Acatodes) elongatus (Gyllenhal, 1826), Coptotomus interrogatus (Fabricius, 1801), Hydaticus (Guignotites) fabricii (MacLeay, 1825), Hydroporus bodemeyeri bodemeyeri Ganglbauer, 1900, and Pachydrus sp. are excluded from the fauna of Iran.

In this study, the faunistic, ecological, and zoogeographical properties of Cerambycidae of the eastern Black Sea Region and also male genitalic structures of some species were examined for the first time in detail. In total, 62 species, 20 tribes, and 36 genera were identified. The Cerambycidae fauna of the eastern Black Sea region share many species with the Middle East and European part of the Western Palearctic.

A new species of Melanoplus belonging to the mancus species group is described from open woodlands on the Cumberland Plateau of Tennessee.

Since the discovery of Melanoplus punctulatus (Scudder) in the western Great Plains in Dawes County, Nebraska in 2014, this grasshopper was later found in northeastern Wyoming in 2018. In 2019 this grasshopper was found in a new county in western Nebraska (Sioux County) at two locations. The Sioux County record represents only the fifth county record for Nebraska and the third county record for any state in the western Great Plains. In addition, many observations of the behavior of this species were made, and are discussed here, particularly in regard to thermoregulation and to how these and other behaviors affect our ability to detect new populations.

The Neotropical carpenter ant Camponotus sexguttatus (Fabricius) has widespread records from the West Indies, Mexico, Central America, and South America. Across its broad native range, C. sexguttatus shows great variation, most notably in color, ranging from almost black to pale yellow. Non-native populations of C. sexguttatus were recorded for the first time in Florida in 1993, and in the Bahamas in 1995. Here, I examine the known native and non-native geographic distribution of C. sexguttatus.

I compiled and mapped C. sexguttatus specimen records from >850 sites, including my own records from 583 sites. Camponotus sexguttatus has West Indian range from Hispaniola, Puerto Rico, and the Virgin Islands in the Greater Antilles through all major islands of the Lesser Antilles. On at least ten islands of the Lesser Antilles, two distinctly different C. sexguttatus color morphs coexist, the typical dark brown/black form plus a lighter form, suggesting that there are at least two separate lines of C. sexguttatus on these islands. Light forms have been previously described on four of these islands as three different subspecies.

Camponotus sexguttatus has a continental range from Mexico, through Central America, to subtropical parts of Argentina, Uruguay, and Brazil. Records from the northern parts of this range, however, are very sparse, e.g., just a single record each from Mexico, Belize, Guatemala, and Honduras, and no records from El Salvador. In addition to the typical C. sexguttatus sexguttatus, seven currently valid subspecies have been described from South America. Genetic analyses should examine whether the different subspecific forms in the West Indies and South America should be considered distinct species.

In its non-native range in peninsular Florida, C. sexguttatus is now known from 16 counties (Brevard, Broward, Collier, Glades, Hendry, Highlands, Indian River, Lee, Martin, Miami-Dade, Monroe, Okeechobee, Orange, Osceola, Palm Beach, and St Lucie), where it is often one of the most common and conspicuous arboreal ants. Variation among C. sexguttatus populations in Florida suggest that they descend from introductions from at least two different source populations. In Bahamas, there are just five records of C. sexguttatus, all from New Providence. It is likely that C. sexguttatus will continue to spread in Florida and the Bahamas, possibly impacting both native and non-native arboreal ants.

A sampling survey for scolytine bark beetles undertaken in Pēpē‘ōpae Bog, part of The Nature Conservancy's Kamakou Preserve on the Hawaiian island of Moloka‘i, revealed the presence there of two native species of the xyleborine genus Xyleborus Eichhoff not previously known from the island: X. obliquus Sharp, 1885, and X. vulcanus Perkins, 1900. We report these new records in detail, discussing their significance to our understanding of the distribution of Hawaiian bark beetles, list all known native species from Moloka‘i together with their known host plants, and provide photographs of the newly recorded beetles, together with a locality map.

The presence of the little-known flea Caenopsylla laptevi lapteviMikulin & Zagniborodova, 1958 is reported for the first time in Turkey. All known hosts and distribution reports of C. laptevi laptevi are outlined and the significance of the new record is discussed. Also, re-descriptions of male and female of C. laptevi laptevi based on Turkish specimens are given. All specimens (three males and two females) of C. laptevi laptevi were collected from a European brown hare, Lepus europaeus Pallas, 1778, which represents a new host record.
