Squamapion gardinii n. sp. from Italy, France and Spain (♂♀; type locality Italy Liguria Genoa Province Genova-Quinto al Mare Rio San Pietro), associated with Thymus vulgaris L., is described. Squamapion solariorum (Wagner, 1908) n. stat., upgraded to species rank from subspecies of Squamapion consors (Desbrochers des Loges, 1875), is redescribed (holotype ♀ examined). New chorological records for Squamapion minutissimum (Rosenhauer, 1856) and Squamapion serpyllicola (Wencker, 1864) are also given; the latter species is recorded for the first time from Italy and Romania. A provisional key is provided to the species of Squamapion, related to Squamapion atomarium (Kirby, 1808), present in the Mediterranean region.The endemic New Caledonian Brachyglutini genus Baraxina is revised. Seventeen species are recognized, of which sixteen are newly described B. francoisi Raffray, 1886; B. amieuana sp. n., B. grimbacheri sp. n., B. kanakorum sp. n., B. rutai sp. n., B. aoupinica sp. n., B. asymmetrica sp. n., B. burwelli sp. n., B. dzumacana sp. n., B. jenisi sp. n., B. koghisiana sp. n., B. lescheni sp. n., B. monteithi sp. n., B. parakoghisiana sp. n., B. pecki sp. n., B. poroana sp. n., and B. wanati sp. n.Oneilliella shivii sp.n. (Panchaetothripinae) is described from India as the second species in this genus. Trachynotothrips brevispinis and T. striatus (Thripinae) are newly recorded from India, and the first description provided of the female of T. brevispinis. Partial sequence data of mitochondrial cytochrome c oxidase (mtCOI) of these species were generated.Four new species of zerconid mites of the genus Halozercon are described and illustrated based on material collected from litter and soil in Altai and Tuva mountains, South Siberia, Russia-H. alataus sp. n., H. gryphus sp. n., H. kumir sp. n. and H. aesopi sp. n. Morphological characters for the new Halozercon species are given. A key for all known species of Halozercon is attached.A new species of cumacean belonging to the genus Diastylis Say, 1818 was collected from the Nokdo Island, Korea. The new species, Diastylis uniplicata sp. https://www.selleckchem.com/products/cpd-37.html nov., can be distinguished from all other Diastylis species by the combination of the smooth carapace surface with a transverse ridge and a pair of oblique ridges, and telson 1.7 times as long as pleonite 6, with 5-6 short stout simple setae laterally. Full illustrations of the new species, including the mouthparts, are given in this paper. Also, a key to the Korean species of Diastylis is provided.A new soft scale species (Hemiptera Coccomorpha Coccidae), Pulvinaria kalyaniensis Talukder Das, sp. n., is described from specimens collected on twigs of Azadirachta indica A. Juss. (Meliaceae) from Kalyani, West Bengal, India. This new species is similar to P. aligarhensis Avasthi Shafee and P. ixorae Green, but can be distinguished by different character states of dorsal areolations, submarginal tubercles, dorsal tubular ducts, the number of prevulvar setae and the number of loculi in each multilocular pore. An updated identification key to the species of Pulvinaria Targioni Tozzetti found in India is provided.Two new species of the green lacewing subgenus Ankylopteryx Brauer are described from southern Yunnan, China, namely Ankylopteryx (A.) diffluens sp. nov. and Ankylopteryx (A.) rubrocincta sp. nov.. An updated key to the species of this subgenus is provided.Two new Beana species (B. mutaneni sp. nov and B. penniuncus sp. nov) are described here. Based on molecular data, Beana nitida Tams is removed to its own genus Beanoides gen. nov. and placed in the subfamily Chloephorinae. Morphological characteristics and DNA barcodes are provided for the new species, with a comparison of morphological structures and genetic distances to Beana terminigera Walker. The current number of valid species in the genus is six.Neuroterus apenninus Trotter, 1923 associated with a Cerris section oak, Quercus cerris L., was rediscovered in Italy in 2017. Alessandro Trotter (1903) described a leaf gall collected on Q. cerris from the Italian Apennines; he did not obtain the gall inductor and ascribed the galls to the genus Neuroterus, based on morphological similarity with other Neuroterus galls. We have found the same gall and obtained the gall inducer. Detailed study of morphological characters of adults revealed that the species belongs to the genus Cerroneuroterus Melika Pujade-Villar, 2010. The asexual generation of Cerroneuroterus apenninus comb. n. is described for the first time, a neotype is designated, and a diagnosis, host associations and biological notes are given; an identification key to the Western Palaearctic Cerroneuroterus species is provided.Cladocera (Crustacea Branchiopoda) of South-East Asia have been intensively investigated over the last decades, but males and ephippial females of many taxa remain unknown or poorly studied. Males and ephippial females of ten species of Chydoridae were collected by monthly sampling of eight water bodies during autumn-winter dry season in Сat Tien National Park, South Vietnam. Morphology of studied specimens is described and taxonomic status of studied species is discussed. Gamogenetic specimens were sparse in all studied taxa, contributing less than 8 % of the populations in samples. Gamogenetic specimens were found mostly during December-January, what suggests that daylight period is the main factor inducing a sexual reproduction in most studied species.The island of Barbuda was recently surveyed for the presence of Haplaxius crudus to establish the risk of Lethal Yellowing to palms on the island. After extensive collecting, H. crudus was not found on the island. A new species of Patara Westwood was found on coconut palms on the southwest portion of Barbuda. Herein, we describe the new species as Patara cooki sp. n. and provide DNA sequence data for cytochrome c oxidase subunit I (COI) and 18S genes for it and Patara guttata Westwood. Patara cooki differed from Patara guttata sp. n. by 1.8% for 18S and 7.8% for COI, similar to intrageneric differences reported for other taxa. A phylogenetic analysis of available Otiocerinae near Patara using found Patara cooki sp. n. nested among other Patara species. We also offer commentary regarding the interpretation of forewing venation in Patara.
