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.
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.
Contributions to the knowledge of the mite genus Stigmaeus Koch, 1836 (Acari: Stigmaeidae) of Turkey
(2017)
Based on the mite specimens collected within the scope of a study on Erzincan (Turkey) mite biodiversity, two species of the genus Stigmaeus are described and illustrated here: S. bifurcus sp. nov. as new to science and S. miandoabiensis Bagheri & Zarei, 2012 as a new record for Turkey. Some morphological abnormalities in the new species are noted. The deutonymph of S. miandoabiensis is described for the first time in this study. Discovery of this stage from soil and litter under Pinus sylvestris in Turkey adds more data to our knowledge of the species.

Dorylaimellus andrassyi, D. discocephalus, D. belondirelloides, D. chakpilus are redescribed based on the specimens collected from several localities of the Western Ghats.
The female of Nothopleurus subsulcatus (Dalman, 1823) (Coleoptera: Cerambycidae: Prioninae: Macrotomini) is described for the first time, and the female of Strongylaspis bullata Bates, 1872 is redescribed. Color photographs of the habitus of both, and key characters for the former are included. New distributional records within Mexico for N. subsulcatus and Strongylaspis championi Bates, 1884 are given.

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.
Pristomerus species of Madagascar are revised. We report 15 species, of which 12 are newly described: P. guinness sp. nov., P. hansoni sp. nov., P. kelikely sp. nov., P. keyka sp. nov., P. moramora sp. nov., P. melissa sp. nov., P. patator sp. nov., P. ranomafana sp. nov., P. roberti sp. nov., P. vahaza sp. nov., P. veloma sp. nov. and P. yago sp. nov. Pristomerus albescens (Morley) and P. cunctator Tosquinet are newly recorded from Madagascar and new host and/or distribution records are provided for this species. A dichotomous key to all species is provided. The zoogeographical relation of the Malagasy fauna of Pristomerus with respect to mainland Africa is discussed: only three of the 15 species are reported to occur outside of Madagascar, suggesting a high level of endemism in Madagascar which was not unexpected.
