Morphological ontogeny of Oribatella similesuperbula Weigmann, 2001 considering specimens from Romania, is described and illustrated. The nymphs of this types are apopheredermous, for example. they carry the exuvial scalps of past instars from the dorsal integument, using changed setal pair da. The prodorsal and most gastronotal setae of juveniles tend to be lengthy and barbed, except for method sized h2 and minute h3 in the larva, and medium size c1, p2 and p3 within the nymphs. The larva has 12 sets of gastronotal setae, the nymphs have actually 15 pairs. In every juveniles, a humeral organ is present.The morphological ontogeny of Ceratozetes parvulus Sellnick, 1922 is explained and illustrated. Some areas of its ecology may also be investigated. The juveniles of the species have actually quick prodorsal and gastronotal setae, tubercles and transverse folds on the gastronotum and setiform bothridial seta. Many knee setae tend to be brief, thick and strongly decreased (lack of setae l on femur III of deutonymph and tritonymph, pl on tarsus we, it on all tarsi, and pv on tarsus IV of nymphs), which are unique in Ceratozetes Berlese, 1908. This species is common in peatlands, where this indicates to prefer particularly drier microhabitats, like hummocks.A brand-new species, Colopalpus hibiscus sp. nov. (Acari Tenuipalpidae) is described from Hibiscus in Hainan province, Asia. The ontogenetic changes in the idiosoma and knee chaetotaxy on adults (feminine and male) and immature phases of this new types tend to be provided. An integral to types of Colopalpus is also provided.A redescription associated with the adult phases of Panonychus caglei Mellott, 1968 (Acari Tetranychidae), is presented centered on new product collected from Japan, and type specimens (holotype and paratypes). Morphological distinctions in the setation of legs have already been reported and dimensions of taxonomic figures are added. We also have described the ontogenetic growth of the juvenile stages. The ventral idiosomal chaetotaxy in larval stage does not have pregenital and genital setae that are included consecutively through development. The pregenital set of setae seems within the protonymphs while the very first set of genital setae is firstly observed in the deutonymphal stage.Rhagovelia medinae sp. nov., associated with hambletoni group (angustipes complex), and R. utria sp. nov., associated with the hirtipes team (robusta complex), are explained, illustrated, and in contrast to Noradrenaline bitartrate monohydrate comparable congeners. In line with the examination of type specimens, six brand-new synonymies tend to be suggested R. elegans Uhler, 1894 = R. pediformis Padilla-Gil, 2010, syn. nov.; R. cauca Polhemus, 1997 = R. azulita Padilla-Gil, 2009, syn. nov., R. huila Padilla-Gil, 2009, syn. nov., R. oporapa Padilla-Gil, 2009, syn. nov, R. quilichaensis Padilla-Gil, 2011, syn. nov.; and R. gaigei, Drake Hussey, 1947 = R. victoria Padilla-Gil, 2012 syn. nov. Initial record from Colombia is presented for R. trailii (White, 1879), plus the distributions associated with the following species tend to be extended in the united states R. cali Polhemus, 1997, R. castanea Gould, 1931, R. cauca Polhemus, 1997, R. gaigei Drake Hussey, 1957, R. elegans Uhler, 1894, R. femoralis Champion, 1898, R. malkini Polhemus, 1997, R. perija Polhemus, 1997, R. sinuata Gould, 1931, R. venezuelana Polhemus, 1997, R. williamsi Gould, 1931, and R. zeteki Drake, 1953.This checklist of oribatid mites regarding the Republic of Colombia compiles and provides a taxonomic improvement of all of the records known up to 2020. It offers 192 entries accounting for 68 known as and 47 unnamed types owned by 73 genera and 58 categories of non-astigmatid oribatid mites. Specimens through the brachypyline supercohort had been prominent (54.7%), accompanied by Mixonomata (30.7%). Nonetheless, present understanding is definately not becoming complete and distribution habits reveal large gaps through the entire nation as a result of this lacking knowledge and a lot of existing investigations only feature team certain studies that avoid from any conclusions in connection with genuine community composition of oribatids in Colombia. From 32 political-administrative divisions, oribatids have already been reported in 20, but 5 account fully for 65% associated with records. They are Cundinamarca -including Bogot D.C.- (24.4%), Magdalena (21.8%), Nario (6.3%), Los Angeles Guajira (6.3%), and Quindo (5.9%). Whereas most oribatid reports in the Neotropical area have taken location in the past system immunology five decades, a map presented in this document suggests that Colombia nevertheless lags behind various other Latin-American countries. Mexico, Argentina, and Brazil, by way of example, have actually reported the greatest range types when it comes to region and are also the only countries that possess nationwide oribatid checklists in Latin America. The current work presents a national baseline of oribatids encouraging further study of this clearly underrepresented group.Ischnura praematura sp. nov. (Holotype , China, Yunnan, Lijiang, 263103.54N, 1001338.89E, 2396 m, 04 xii 2015, I. Sanmartn-Villar H. Zhang knee.) is morphologically explained, illustrated and compared with close species of the genus. Ischnura praematura may be primarily distinguished from its congeners I. aurora, I. rubilio and I. asiatica by its stomach and thoracic morphology and colouration. The posterior lobe for the prothorax is raised in I. praematura as well as the mesostigmal plates possess dorsal triangular protuberances. Ischnura praematura shows pointed paraprocts, internalised wide cerci and lacks a dorsal tuberculum into the tenth stomach segment. The blue abdominal colouration is present in the last three sections (incomplete for segment eight and ten in some individuals). No female polychromatism had been detected and all females observed possessed different colouration than male (gynochrome). Morphological distinctiveness of this species is supported by genetic analyses, which reveal that I. praematura forms a well-supported, monophyletic clade, with I. asiatica, I. ezoin and I. pumilio as the most closely related species. On the go, mature females show powerful reluctance to mate, and males were seen mating with newly emerged females.Tenupalpa Lee et Li, 2021 (Gelechiidae Thiotrichinae) had been recently suggested according to a molecular and morphological study associated with the subfamily. It presently includes six species primarily proinsulin biosynthesis known from Russia, Japan and India.
