A diagnostic key to the identification of the valid species of this genus is provided.
Coilodes Westwood, 1846 is a Neotropical genus of Hybosorinae. Despite being a morphologically homogeneous genus, it presents a great deal of intraspecific variation, especially with reference to the colour of integuments. This makes identification of species even more difficult, since the majority of original descriptions present the colour as the main diagnostic character. To solve this problem, the first taxonomic revision of Coilodes is presented. The genus now comprises 13 species. Redescriptions of C. castaneus Westwood, 1846, C. fumipennis Arrow, 1909, C. humeralis (Mannerheim, 1829), C. niger (Mannerheim, 1829), C. ovalis Robinson, 1948, C. parvulus Westwood, 1846, and C. punctipennis Arrow, 1909 are presented. Coilodes niger (Mannerheim, 1829) has its status revalidated and three new synonyms are proposed: C. gibbus (Perty, 1830) and C. chilensis Westwood, 1846 with C. humeralis, and C. nigripennis Arrow, 1903 with C. castaneus. Biological and geographical distribution data are expanded. Lectotypes are designated for C. humeralis and C. niger. Six new species are described: C. bezerrai Basílio & Vaz-de-Mello sp. nov., C. edeiltae Basílio & Vaz-de-Mello sp. nov., C. lunae Basílio & Vaz-de-Mello sp. nov., C. mayae Basílio & Vaz-de-Mello sp. nov., C. ravii Basílio & Vaz-de-Mello sp. nov., and C. skelleyi Basílio & Vaz-de-Mello sp. nov. An identification key for the males of the species is presented.
Five species of the cheiracanthiid spider genus Cheiracanthium C.L. Koch, 1839 collected from China are diagnosed and described as new to science based on morphological characters: Cheiracanthium arcilongum sp. nov. (♂♀) from Yunnan, C. circulum sp. nov. (♂♀) from Yunnan, C. digitatum sp. nov. (♂♀) from Anhui, C. jiuquan sp. nov. (♂♀) from Guangxi and C. xinjiangense sp. nov. (♂♀) from Xinjiang. In addition, the photos of the habitus, copulatory organs and distribution map are provided for all species. However, DNA barcodes information is only provided for four species.
Four new species of Alloxysta (Hym.: Cynipoidea: Figitidae: Charipinae) from Petr Starý’s collection
(2023)
After the revision of Petr Starý’s Charipinae collection, four new species of Alloxysta Förster, 1869 have been found. This collection represents a good overview of the Charipinae fauna worldwide, although the best represented area is Central Europe. Here, we describe four new species of Alloxysta: A. llumae Ferrer-Suay sp. nov., A. onae Ferrer-Suay sp. nov., A. poli Ferrer-Suay sp. nov. and A. staryi Ferrer-Suay & Pujade-Villar sp. nov. Three of these new species are based on reared specimens. Diagnosis, distribution, and description of the new species are given and illustrated.
Three new species of the genus Pelodera Schneider, 1866 viz., P. indica sp. nov., P. adeeli sp. nov. and P. paratretzeli sp. nov. collected from dung beetles and P. cylindrica (Cobb, 1898) collected from soil samples, are described and illustrated. Pelodera indica sp. nov. is characterised by sexual dimorphism in anterior region, cupola-shaped tail with a spike; males having punctated, striated and lobed bursa with no genital papillae originating anterior to cloaca. Pelodera adeeli sp. nov. is characterised by coarsely annulated cuticle; relatively narrow stoma; tail conoid without spike; males with punctated, lobed bursa and nine pairs of genital papillae arranged in a 2/1+2+P+3+1 configuration. Pelodera paratretzeli sp. nov. is characterised by sexual dimorphism in anterior region, stoma wide with three well-developed metastegostomal denticles; tail cupola-shaped with a long spike; males having spicules fused distally up to 12–14% of spicule length; bursa peloderan, anteriorly closed and punctated with nine pairs of genital papillae arranged in a 3/2+P+3+1 configuration. Pelodera cylindrica is described with additional details. The comparative analysis as well as phylogenetic relationship of the species belonging to the coarctata group have been elaborated by incorporating scanning electron microscopic observations. Information on the biogeographical distribution has also been provided.
A list of abbreviations regarding literature, collections and persons as used by early authors (1758–1779) of scarabaeoid beetles (Insecta: Coleoptera) is given together with modern referrals to the Literature Cited. Notes regarding referential errors are included. Hyperlinks to all mentioned and freely online available publications are provided.

Seven new species of the genus Meta C.L. Koch, 1836 from Southwest China are described here: M. bowo sp. nov. (♂♀), M. cona sp. nov. (♂♀), M. gyirong sp. nov. (♂), M. hongyuan sp. nov. (♂♀), M. tibet sp. nov. (♂♀), M. wanglang sp. nov. (♂♀) and M. weining sp. nov. (♂♀). Detailed descriptions, photos of somatic features and copulatory organs as well as line drawings, comparisons with closely related species, and a distribution map are provided.
The classification of the genera belonging to the doryctine tribe Rhaconotini (Braconidae) is updated. The following new taxa are described: Troporhaconotus gen. nov. (with 12 species), Afroipodoryctes subgen. nov. (of Ipodoryctes Granger, 1949) (with three species), Hexarhaconotinus subgen. nov. (of Rhaconotinus Hedqvist, 1965) (with ten species), Bathycentor zimbabwensis sp. nov., Ipodoryctes (Afroipodoryctes) reunionus sp. nov., I. (A.) saintphilippensis sp. nov., Platyspathius (Platyspathius) venezuelicus sp. nov., P. (P.) ranomafanus sp. nov., Rhacontsira haeselbarthi sp. nov., Rh. mozambiquensis sp. nov., Rh. saigonensis sp. nov. and Rh. toamasina sp. nov. The generic status of Euryphrymnus Cameron, 1910 is resurrected. The generic name Aptenobracon Marsh, 1965 is synonymised under Rhaconotus Ruthe, 1854 (syn. nov.); Rhaconotus asiaticus Belokobylskij, 1990 is synonymised under Rh. kerzhneri Belokobylskij, 1985 (syn. nov.). The new name, Rhaconotinus austrochinensis nom. nov., is suggested for the preoccupied name Rhaconotus chinensis Chen & Shi, 2004 (December) not Rhaconotus chinensis Belokobylskij & Chen, 2004 (June). New species contents, in many cases with numerous new combinations, are suggested for the genera Bathycentor Saussure, 1892, Euryphrymnus Cameron, 1910, Ipodoryctes Granger, 1949, Rhaconotinus Hedqvist, 1965 and Rhaconotus. The tribe Leptorhaconotini is synonymised with Rhaconotini based on previously published molecular phylogenetic studies, though we leave this group within the subtribe Leptorhaconotina.
