An updated checklist of the Arabian species of Bethylidae is provided here. The list includes 29 identified valid species in 25 genera and five subfamilies Bethylinae (2 genera, 0 species), Epyrinae (5 genera, 8 species), Mesitiinae (7 genera, 13 species), Pristocerinae (5 genus, 1 species) and Scleroderminae (6 genera, 7 species). Distributions, both on the Peninsula and extra-limital, are provided for each species; 17 species (59%) are endemic to the Arabian Peninsula.An updated checklist of the Arabian species of Sphecidae is provided here. The list includes 70 identified valid species in 10 genera and four subfamilies Ammophilinae (4 genera, 35 species), Chloriontinae (1 genus, 6 species), Sceliphrinae (2 genera, 8 species) and Sphecinae (3 genera, 21 species). Distributions, both on the Peninsula and extra-limital, are provided for each species and subspecies; four species (6%) are endemic to the Arabian Peninsula.An updated checklist of the Arabian species of Heterogynaidae is provided here. The list includes two identified valid species in one genus. Distributions on the Peninsula are provided for each species; both (100%) are endemic to the Arabian Peninsula.An updated checklist of the Arabian species of Crabronidae is provided here. DJ4 The list includes 383 identified valid species in 54 genera and seven subfamilies Astatinae (3 genera, 16 species), Bembicinae (10 genera, 86 species), Crabroninae (27 genera, 199 species), Dinetinae (1 genus, 3 species), Eremiaspheciinae (2 genera, 7 species), Pemphredoninae (7 genera, 14 species) and Philanthinae (4 genera, 58 species). DJ4 Distributions, both on the Peninsula and extra-limital, are provided for each species and subspecies; 77 species (20%) are endemic to the Arabian Peninsula, as is one subspecies.An updated checklist of the Arabian species of Ampulicidae is provided here. The list includes four identified valid species in three genera and two subfamilies Ampulicinae (2 genera, 3 species) and Dolichurinae (1 genus, 1 species). Distributions, both on the Peninsula and extra-limital, are provided for each species; of these, one (25%) is confined to the Arabian Peninsula.The current knowledge of the distribution and diversity of extant aculeate wasps (Aculeata excluding ants and bees) in the Arabian Peninsula (and Socotra) is reviewed. The number of species (1096 of which about 28% are apparently endemic) represents about 3% of the world fauna, with Crabronidae the most diverse family (about 35% of Arabian species). Most species (46%) are Afrotropical, 37% are Palaearctic, and 17% are Indo-Malayan (Oriental).During the past 20 decades, many taxonomic and ecological studies were undertaken on different taxa of a fascinating, biologically diverse group of insects, the aculeate wasps, in different areas of the Arabian Peninsula. These wasps comprise all Aculeata, except for the ants (Formicidae) and bees (Anthophila) which are specialized monophyletic groups that have attracted more focused attention across the world. The Arabian studies have been published in the form of scattered articles in various journals, newsletters, book chapters, etc., many being rather obscure and difficult to trace. Recently, the number of such studies has increased as a result of targeted collecting projects. The results of most of these have now been published, making this an opportune time to collect all the available information into a single volume that makes it more accessible to researchers interested in this group of insects. In the process, this provides us an opportunity to estimate the diversity and distributions of aculeate wasps in the Arabian countries. This is also important for the development of the Arabian national collections, especially in aggregating taxonomic changes with their subsequent synonymous forms and pointing out the very many gaps in sampling, so indicating where additional work is needed.A list of genus names in the scale insects published between 2014 and the end of 2019 is provided; it follows on from an earlier comprehensive list of the names published between 1758 and the end of 2013. Each genus name and its type species are assigned to one of the 53 scale insect families now recognised.The majority of tyrannosauroid phylogenies published in the last 10 years have recovered a clade of basal tyrannosauroids that include Stokesosaurus clevelandi Madsen, 1974, Eotyrannus lengi Hutt et al., 2001 and Juratyrant langhami (Benson, 2008), which is positioned between Dilong Xu et al., 2004 and more derived tyrannosauroids such as Xiongguanlong Li et al., 2010 (e.g., Brusatte et al., 2010, 2011; Brusatte and Benson, 2013; Lü et al., 2014; Brusatte and Carr, 2016; Yun, 2016; Carr et al., 2017; Delcourt and Grillo, 2018; Nesbitt et al., 2019; Zanno et al., 2019; Wu et al., 2020). Carr et al. (2017) first called this clade as "Stokesosauridae", but did not define or diagnose this clade; but later the name was adopted and used as valid by Wu et al. (2020).Chaetonerius Hendel is the only native genus of Neriidae from the African continent, with 21 species described. Although widely distributed across the Afrotropical region, the species of Chaetonerius are still poorly known and recent efforts are being devoted to clarify the taxonomy of the family and discover its diversity. Here, we describe a new neriid species from Tanzania, Chaetonerius stichodactylus sp. n. Illustrations of the male holotype, including the external and internal genitalia, are presented and a key for the species of Neriidae of Tanzania is provided.This paper reports three new species of the genus Nazeris Fauvel, 1873 from mainland China, namely Nazeris mahuanggouensis Su, Li and Zhou, sp. nov. and Nazeris zhouhaishengi Su, Li and Zhou, sp. nov. from Sichuan Province, Nazeris wuluozhenensis Su, Li and Zhou, sp. nov. from Guizhou Province. For all species included we offer color plates of normal light photos for general morphology and detailed aedeagus structures.Two new species of Silba Macquart, 1851 namely Silba mitsuii sp. nov. and Silba fungicola sp. nov. are described from Japan. The adults of the first species were obtained from larvae found in the flower buds of Camellia japonica L. and of the second from fungal fruiting bodies. This is the first time these types of larval habitat have been recorded for a Silba species.
