Abstract: Here, we present the first record of Sphingonotus (Sphingonotus) savignyi savignyi Saussure, 1884, for Mongolia, collected from the Gobi area. This collection location defines the currently most north-eastern collection location of the species.

Abstract: Pachymelus Smith, 1879, is a small bee genus comprising 21 species restricted to sub-Saharan Africa and Madagascar. Despite the small size of the genus, several uncertainties persist within the subgenus Pachymelus (Pachymelopsis) Cockerell, 1905, which contains five species and is restricted to sub-Saharan Africa. Based on a revision of museum material and inspection of contemporary collections, a number of changes are implemented. Pachymelus bettoni (Cockerell, 1910), described in the male sex, was incorrectly considered to be a distinct species; it is actually the male of Pachymelus (Pachymelopsis) conspicuus Smith, 1879, syn. nov., and is returned to synonymy with it. Pachymelus (Pachymelopsis) armatipes (Friese, 1911), stat. rev. is returned to species status, having been incorrectly considered conspecific with P. conspicuus. Pachymelus (Pachymelopsis) haladai sp. nov. is described from Ethiopia. A lectotype is designated for Habropoda capensis Cameron, 1905 (= Pachymelus festivus (Dours, 1869)) from material that was previously considered lost; the species is newly reported from East Africa (Kenya), and the status of Afromelecta lieftincki Eardley, 1991 is discussed. The type locality of Pachymelus (Pachymelopsis) abessinicus (Friese, 1912) is clarified, moving from Uganda to Kenya, which is shown to host five of the now six members of this subgenus. These revisions further illustrate the need for greater survey effort and taxonomic revision of bees in dry parts of Eastern Africa.

Abstract: A new case of hemidystrophy in Trogidae is here described and illustrated. The teratological specimen was identified as a male of Omorgus (Omorgus) alternans (MacLeay, 1827), being the first record of a teratological specimen of a trogid from Australia. While teratological cases provide limited taxonomic insights, they offer significant understanding of the environmental influences on insect development. The study emphasizes the importance of documenting such anomalies, contributing to the broader knowledge of developmental biology in insects, particularly within the under-researched Australian Trogidae

Abstract: This paper presents all available information on the Orthoptera of the Socotra Archipelago, an area well-known for its endemic flora and fauna. General information is provided about the climate and geology of the Socotra Archipelago. The various habitats where grasshoppers have been found are described and illustrated, followed by a concise history of Orthoptera research on Socotra. Besides an identification key to the species, additional information about the material examined, taxonomy, diagnostic notes, distribution and occurrence, including maps, habitat, biology and bioacoustics, is provided for each species. In total, 65 Orthoptera species are reported here from Socotra, Abd el Kuri, Samha and Darsa, including Oecanthus castaneus Felix & Bouwman, sp. nov. and two unknown species assigned to Ectatoderus. Of these 65 species, 30 (46%) are endemic to the Socotra Archipelago. Re-descriptive notes on Acrotylus innotatus Uvarov, 1933 and Glomeremus capitatus Uvarov, 1957 are provided, including the description of the female of the latter species and the male of Oxytruxalis ensis (Burr, 1899). Acrotylus innotatus Uvarov, 1933, Dictyophorus griseus (Reiche & Fairmaire, 1850), Eumodicogryllus chivensis (Tarbinsky, 1930), Ochrilidia geniculata (Bolívar, 1913), Sphingonotus rubescens (Walker, 1870) and S. balteatus (Serville, 1838) are recorded for the first time from the Archipelago. Bioacoustics are presented for: Ochrilidia socotrae Massa, 2009, Stenohippus socotranus (Popov, 1957), Sphingonotus ganglbaueri Krauss, 1907, S. insularis (Popov, 1957), Acheta rufopictus Uvarov, 1957, Eumodicogryllus chivensis (Tarbinsky, 1930), Ectatoderus guichardi Gorochov, 1993 as well as two other species assigned to Ectatoderus, Oecanthus castaneus Felix & Bouwman, sp. nov., Ruspolia aff. R. basiguttata (Bolívar, 1906) and Pachysmopoda abbreviata (Taschenberg, 1883). Red List Assessments for 29 endemic species have been prepared including Oxytruxalis ensis (Burr, 1899) (Critically Endangered, CR), Cataloipus brunneri (Kirby, 1910) (Endangered, EN) and Glomeremus capitatus Uvarov, 1957, Phaneroptila insularis Uvarov, 1957, Phaulotypus granti Burr, 1899, Socotracris kleukersi Felix & Desutter-Grandcolas, 2012, Socotrella monstrosa Popov, 1957 and Xenephias socotranus Kevan, 1973 (all Vulnerable, VU).

Abstract: Heilipus Germar, 1824 (Coleoptera, Curculionidae, Molytinae, Molytini, Hylobiina) is a largely understudied tropical lineage of weevils with 90 described species distributed from the southern United States to northern Argentina. Several of its species cause damage to avocado (Persea americana Mill.; Lauraceae Juss.) crops in the Americas. Apart from the species of economic importance, there is a paucity of information regarding the host plants of species of Heilipus. This study presents a comprehensive overview of the current knowledge on the habits and host plants of this group of weevils, based on a literature review and the examination of label data associated with entomological material in museums and scientific collections. The larval stages of 24 Heilipus species are borers of either seeds or trunks of 38 plant species belonging to 13 genera: 33 species (12 genera) from the family Lauraceae and five species (one genus) from the family Annonaceae Juss. Four new host plant records and the first identification of habits and host plants for H. albovenosus (Champion), H. empiricus (Pascoe), H. fassli (Voss) and H. mirus (Pascoe) are provided. The biology and host plants of the seed and trunk borers are discussed, as well as the oligophagous feeding behaviour exhibited by these two feeding guilds. Seed-boring Heilipus species constitute one of the primary groups of pre-dispersal seed predators of the family Lauraceae in the Americas. Furthermore, the high diversity of Heilipus and its host plants in the Brazilian Atlantic Forest suggests that this area may be a possible centre of origin for these weevils.

Abstract: Within the genus Hylaeus subgenus Deranchylaeus, from sub-Saharan Africa, a distinctive new subgroup of species is established. The females of this subgroup share a striking character: the orange-coloured lower face, previously known only in H. xanthostoma. The inter-specific differences are cryptic in both sexes. Seven species are newly described: Hylaeus (Deranchylaeus) aurantiacus sp. nov. ♀♂, H. (D.) burundis sp. nov. ♂, H. (D.) lyriformis sp. nov. ♂, H. (D.) sambiensis sp. nov. ♂, H. (D.) portokalius sp. nov. ♂♀, H. (D.) diastictus sp. nov. ♂ and H. (D.) jemeniticus sp. nov. ♀. This subgroup also includes H. (D.) promontorii (Meade-Waldo, 1923) and H. (D.) venustus Dathe, 2014, whose females are described for the first time. From Cameroon, the male of a second species of the subgenus Pumilaeus is described as new: H. (Pumilaeus) soukontouai sp. nov. New records of species of the genus Hylaeus F. in sub-Saharan Africa are added and a revised identification key to the subgenus Deranchylaeus is presented, to include the new species.

Abstract: New taxonomic, biological and faunistic data are presented for some species of sawflies occurring in southern Europe and North Africa. Pamphilius mediterraneus sp. nov. is described from Italy (Sicily). It belongs to the alternans sub-group of the alternans species group. Pristiphora omalos sp. nov. is described from Greece (Crete). It belongs to the depressa species group. New junior synonyms are Calameuta tazzekae Lacourt, 1991 of Calameuta gaullei (Konow, 1896), and Emphytus leucostomus Costa, 1890 of Allantus cingulatus (Scopoli, 1763). Periclista rufiventris Zombori, 1979 is moved from the subgenus Periclista to the subgenus Neocharactus. Ametastegia (Protemphytus) persica Khayrandish, Talebi & Blank, 2015 is recorded for the first time in Europe, from Italy (Sicily), and a key to West Palaearctic Protemphytus species provided. Allantus enslini (Forsius, 1918) is more widespread in southern Europe than previously recorded. An identification key distinguishes it from its closer West Palaearctic relatives. New hostplant records are for Halidamia affinis (Fallén, 1807) (Rubia peregrina), Janus compressus (Fabricius, 1793) (Sorbus torminalis), and Macrophya albicincta (Schrank, 1776) (Centranthus ruber). New distribution records are given for a few other species.
