One of the most phylogenetically enigmatic taxa of Trombidiformes is the supercohort Eupodides (=Eupodina) consists of five superfamilies: Bdelloidea, Eriophyoidea, Eupodoidea, Halacaroidea, and Tydeoidea. However, this taxonomic system has not been supported by formal reconstruction of the phylogeny of these mite groups. In this paper, we present the results of the phylogenetic relationships of major lineages of Eupodides based on 18S rDNA, 28S rDNA, and COI sequences. By critically analysing the key morphological features of the mite taxa indicated by molecular analysis as the main eupodine lineages, we reconstructed a cladogram showing the cladistic hypothesis of the internal phylogenetic structure of Eupodides. Subsequently, the result was compared to the character evolution course suggested by tracing the morphological characters of eupodine mites on the reconstructed molecular tree. According to our data, Eupodides should still be classified as a monophyletic taxon grouping representatives of Bdelloidea, Eupodoidea, Tydeoidea, and Eriophyoidea; however, the taxonomic status of some superfamilies was not confirmed. Particularly, only the bdelloid clade with Cunaxidae nested within Bdellidae may correspond to the superfamily in the current taxonomic view. Additionally, the superfamilies Eupodoidea and Tydeoidea were demonstrated to be paraphyletic. Moreover, morphological, as well as molecular, data recovered Eriophyoidea nested within Tydeoidea.

Altogether, 31 species were collected and identified from 48 collecting localities. Detailed geographical distribution data are presented for all species recorded from Jiangxi, of which three new species are herein described and illustrated: Habroloma flavopilosulumsp. nov.; H. shengisp. nov. and H. tianpaishanensissp. nov., 10 species are regarded as new to Jiangxi Province.
Since the description of Ptilophorus dufourii (Latreille, 1818), the unknown immature stages and biology of Ptilophorinae is one of the longest persisting gap in the research of the wedge-shaped beetles (Ripiphoridae). Here we describe the primary larva of P. dufourii based on SEM and CLSM images. Its modified mouthparts unsuitable to grasp prey rule out predaceous habits and also processing any solid substrates (e.g., wood or other fresh plant tissues). In contrast, the weakly sclerotized and very small body, the enlargement of the sensorial appendage of the antennae, and simplified mouthparts strongly suggest parasitism and consumption of liquid food. We provide a comparison with the only known larva of Pelecotominae, another possible basal lineage of Ripiphoridae, and discuss potential synapomorphies and differences between larvae of both subfamilies. A sistergroup relationship between Ptilophorinae and Pelecotominae is suggested by the presence of only two stemmata, spatulate femoral setae, a scale-like lateral cranial surface, and an enlarged antennal sensorial appendage, and a clade Ripidiini + Ripiphorinae by a characteristic boat-shape of the primary larvae. The host of P. dufourii remains unknown. We reviewed published host records, but none of them is based on traceable evidence and none of them appears credible. Observations of adult behaviour of P. dufourii are documented. Taxonomy and systematics of Ptilophorus and Ptilophorinae are discussed. The Cretaceous Spinotoma ruicheni Hsiao et Huang, 2017 is transferred from Pelecotominae to Ptilophorinae in accordance with diagnostic characters given in the original description and current definitions of both subfamilies.
Lagriine genus Strongylagria Pic, 1915 was found congeneric with DonaciolagriaPic, 1914.

The genera of Australian Dermestidae are revised based on the results from the recent molecular phylogeny research. Revised classification of Australian Dermestidae includes more than 130 described species classified in 20 genera in six subfamilies. Subfamily Orphilinae LeConte, 1861 includes only RanolusBlair, 1929 (three species); subfamily Trinodinae Casey, 1900 includes Evorinea Beal, 1961(one species), Trinoparvus Háva, 2004 (one species), ThylodriasMotschulsky, 1839 (one introduced species) and TrichelodesCarter, 1935 (one species); subfamily Trogoparvinae Zhou et al, 2022 includes Trogoparvus Háva, 2001 (two species, including T. cockatoosp. nov. from Queensland) and Attagenoparvusgen. nov. (one species, T. calperumsp. nov. from South Australia); subfamily Dermestinae Latreille, 1804 includes only Dermestes Linnaeus, 1758 (four introduced and one native species); subfamily Attageninae Laporte de Castelnau, 1840 includes AdelaidiaBlackburn, 1891 (two species), AttagenusLatreille, 1802 (three introduced species), Aethriostoma Motschulsky, 1858 (two species), Katkaenus Háva, 2006 (one species) and TelopesRedtenbacher, 1843 (one introduced species); Megatominae Leach, 1815 includes AnthrenusGeoffroy, 1762 (one introduced species), Orphinus Motschulsky, 1858 (11 species), ThaumaglossaRedtenbacher, 1867 (one species), Eurhopalus Solier in Gay, 1849 (95 species), PhradonomaJacquelin du Val, 1859 (one introduced species) and Trogoderma Latreille, 1821 (three introduced species).
Species diversity is remarkable especially in Dorcadion genus, which spreads in Europe and the Caucasus. Most members of the genus are incapable of flight, generally isolated, and some are endemic. Therefore, there are many studies on the distribution and diversity of species of Dorcadion. However, there is no study on endosymbiotic bacteria that play a critical role in the ecology, physiology and evolution of arthropods. In this study, endosymbiotic Wolbachia bacteria were investigated in members of D. cruxBilberg, 1817, D. micans micansThomson, 1867, D. anatolicumPic, 1900, D. septemlineatumWaltl, 1838 and D. scabricolleDalman, 1817, collected from six different localities. Studies were performed with the Wspec-F/R primer pair. Two of the five examined species of Dorcadion (D. septemlineatum and D. micans micans) are not infected by Wolbachia. On the other hand, Wolbachia (supergroup B type) with the same consensus sequence was detected in D. anatolicum, D. scabricolle and D. crux. Interestingly, Wolbachia, which was thought to be accidental, was found to be common in males, but unfortunately this could not be explained by the data set obtained. However, considering the variations in Dorcadion species and the evaluations according to them, it can be claimed that there is no ordinary association between this taxon and Wolbachia. We hypothesize that among the possible explanations for the large morphological variability in Dorcadionini is the influence of the maternally inherited endosymbiotic Wolbachia. Therefore, we believe that the data obtained in this manuscript will contribute to studies on Dorcadion diversity and distribution.
Crematogaster ghoneimi, sp. nov. is described from the southwestern mountains of the Kingdom of Saudi Arabia (KSA) based on the worker caste. The new species is most similar to C. chiarinii Emery, 1881, type locality Ethiopia, and can be readily distinguished from all other regional congeners by the long, thin, and acute propodeal spines, presence of a single pair of hairs on the promesonotum, and lacking a subpetiolar process.
Two species Melanopachycerina guizhouensissp. nov. and Melanopachycerina processasp. nov. are described as new to science. A key to separate world species of the genus Melanopachycerina is provided.
The basal classification of planthoppers (Hemiptera Fulgoromorpha) is revised. The wrinkled ambient vein (appendix) on the fore wing is given as an apomorphic character for the Fulgoromorpha for which the Pennsylvanian, Moscovian genus Aviorrhyncha (310 Mya), Aviorrhynchidae, is the oldest representative to date. All other planthopper taxa belong to the informal eucixioidean lineage. Coleoscytoidea and Surijokocixiioidea are downgraded to the family level. Permian genus Reticulocicada is formally transferred from Hemiptera incertae sedis to Coleoscytidae. Fulgoridiidae are reviewed and upgraded to superfamily Fulgoridioidea superfam. nov. Superfamilies Fulgoroidea stat. nov. includes all extant families, except families Cixiidae, Delphacidae, and Lalacidae grouped into Cixioidea superfam. nov., while Jubisentidae, Mimarachnidae, Neazoniidae and Perforissidae remain incertae sedis families in the eucixioidean lineage. Rather than being seen as a “stratigraphic taxon” (e.g., all Jurassic planthoppers belong to Fulgorididiidae), monophyly of Fulgoridioidea is confirmed, based on a complex synapomorphic character: posterior branches of the CuA aligned in series along the CuP, arising from two successive prenodal nodes, and whose anterior branches emerge distinctly anteriorly. Accordingly, the taxonomic composition of Fulgoridioidea includes: 1) Fulgoridiidae (restricted to genera Cixiites, Eofulgoridium, Stonymetopus, Fulgoridium (type genus) and Valvifulgoria, 2) the already described families: Jurassic Qiyangiricaniidae, Triassic Szeiinidae, mid-Cretaceous taxa Dorytocidae, Inoderbidae, Katlasidae; 3) several incertae sedis genera transferred from Perforissidae: Aafrita, Aonikenkissus, Foveopsis, Iberofoveopsis, Lanlakawa, aberrant paratype specimen of Tsaganema oshanini, and genus Aulieezidium excluded from Fulgoridiidae, and 4) the Eocene taxa Weiwoboidae and genus Emiliana transferred from Tropiduchidae. In reverse, genera Compactofulgoridium, Conofulgoridium, Fenghuangor, Fulgoridiella, Fulgoridulum, Fulgoropsis, Margaroptilon, Metafulgoridium, Parafulgoridium, Procercofulgoridium, Productofulgoridium and Tetrafulgoria, are excluded from Fulgoridiidae and transferred to eucixioidean lineage incertae sedis.
The whitefly genus Rhachisphora Quaintance & Baker is reported for the first time from the Andaman Islands. Puparia and earlier stages of immatures of a new whitefly, R. saddlensissp. nov. found infesting Semecarpus kurzii Engl. (Anacardiaceae) are described with illustrations of its habitus on the leaf, line drawings, photographs, and SEM microphotographs of the type specimens are provided. Puparia of the new species differ from other Rhachisphora species in having an elongate cordate vasiform orifice, a row of submarginal pores and the caudal tracheal pore deeply inset from the margin. The new whitefly is dimorphic in which female puparia are larger than the male puparia and found feeding on both surfaces of the leaves. In addition, an identification key to Rhachisphora species known from India is provided.
A new monotypic genus of ricaniid planthoppers (Hemiptera: Fulgoromorpha: Ricaniidae), Tarehymalahelogen. nov., is described for Tarehymalahelo meridianasp. nov. (type species), based on male and females collected in the spiny forests ecoregion of south Madagascar. Habitus, external and internal genital structures of the new species are described and illustrated.
A new genus and species of planthopper – Yobuenahuaboshka rectangialatusgen. et sp. nov., preserved as inclusion in late Lower Miocene, Burdigalian amber from Hispaniola (Dominican Republic) is described and illustrated. Classification and fossil records of the family Nogodinidae, and their issues, are briefly overviewed. The morphological characters of the new taxon with related recent and fossil Colpopterini are discussed. Hypotheses based on the distributional pattern of the Colpopterini and geotectonic events in the Caribbean, with dispersal over water barriers, through more or less continuous landmasses as well as continent-island are presented.
