As a whole, 300 species, belonging to 110 genera, 38 people, 23 instructions, and three classes had been recognized from Iranian basins, using the presence of 11 reported types that need confirmation by specimens. Extra notes about the taxonomy of several taxa are provided when you look at the discussion section.Thirteen brand-new files of Goniasteridae showing mesophotic event are provided, including a new types of Pseudoceramaster doto n. sp. from south Japan and a fresh genus and species, Churaumiastra hoshi nov. gen. nov. sp. which happens in south Japan, the Philippines and Western Australia.A new subspecies of Lithoxenus haptapotamicus minutus Korsunovskaya subsp. nov. and new shade form of Eulithoxenus mongolicus caeruleum tend to be described. Data concerning the male calling tune of L. miramae (Velt.) in addition to framework for the sound apparatus of Eulithoxenus mongolicus Uv.and L. miramae is given to the 1st time.The seta, a form of projection of the cuticle in crustaceans, has essential technical and physical features. As a result of diversity of their morphology and distribution habits from the articles of different appendages, setae are a good idea as taxonomic characters. To aid future researches in the prospective utilization of Taiwan Biobank setae as a diagnostic personality in aeglids, we utilized checking electron microscopy to evaluate the morphology of setae through the dental apparatus of Aegla longirostri Bond-Buckup & Buckup, 1994, and compared our information into the literary works. We identified nine setal kinds (simple, serrate, stout serrate, sword, plumose, pappose, comb, serrulate, and cuspidate), of that the final two was not formerly explained in adult aeglids. Our results are a primary step towards future comparisons of setal morphology in the genus Aegla, which includes cryptic types complexes, to determine the usefulness of setae as a character to assist in the information of species of this team, that has a conserved general morphology.A list of acrodont lizard type specimens extant when you look at the Naturalis collection is presented here the very first time. The collections combines original specimens of this previous Rijksmuseum van Natuurlijke Historie, Leiden (RMNH) and also the previous Zologisch Museum Amsterdam (ZMA). Presently the Naturalis collection holds primary kinds of 25 agamid lizard species (11 holotypes, six lectotypes and syntypes for eight types, including types of two species where in actuality the type status is not clear) along with numerous additional kinds for 22 types (14 para- and eight paralectotype series). Type material present in the collection presents 29 currently legitimate agamid lizards taxa and three currently valid chameleon taxa.A new species for the micrasterid genus Micraster, Micraster ernsti sp. nov., is explained from the Lower Campanian from the Hannover location (Lower Saxony, Germany). This species shows a peristome that is not near the anterior margin, an only moderately-projecting labrum with a smooth rim and well-developed phyllodes, contrary to contemporary Micraster species. These morphologies might have been the result of an adaptation to feeding from within the inhabited sediment, in the place of from the sediment-water screen. This eating method unveils an ecological niche perhaps not occupied by the co-occurring Micraster species.During a research performed from the Surgical Wound Infection helminth fauna of fishes in the centre Munim River basin, State of Maranho, northeastern Brazil, three species (two new) of Diaphorocleidus Jogunoori, Kritsky & Venkatanarasaiah, 2004 tend to be reported through the gills of the piaba Bryconops cf. affinis (Iguanodectidae) Diaphorocleidus affinis (Mizelle, Kritsky & Crane, 1968), D. forcipiformis n. sp. and D. munimensis n. sp. New morphological information, drawings, and geographic distribution were provided for D. affinis. Diaphorocleidus forcipiformis n. sp. is characterized by a male copulatory organ with 2 rings counterclockwise and base forming a tiny tube with two circular flanges and accessory piece bifurcated, claw-shaped, with components similar fit and size, certainly one of all of them distally bifid. Diaphorocleidus munimensis n. sp. is differentiated by the accessory piece, that is consists of two big pieces, united inside their proximal part, claw-shaped, and distally hooked. The conclusions for this initial survey regarding the helminth parasites of fishes in this region stress the necessity of performing similar surveys on various other seafood types. Such surveys can result in the recognition of unknown species or brand-new occurrences.Two brand-new types of Grotea Cresson are explained from Brazil, Grotea claudiae Kumagai sp. n. and G. fernandoi Lima sp. n. New documents and recognition secret for Brazilian types of Grotea are supplied check details . Grotea amazonensis Herrera-Flrez, 2019 is proposed as nomen nudum.First Upper Triassic dipterans (Nematocera) are described according to isolated wings from Fuchsberg near Seinstedt (Sevatian, uppermost Norian of Lower Saxony, Germany) Crivoptychoptera nebrias gen. et sp. nov. (Psychodomorpha, Ptychopteridae), Ptychopteridae incertae sedis, Dohloboyia triassica gen. et sp. nov. (Bibionomorpha, Boholdoyidae) and Chironomidae incertae sedis (Culicomorpha). All taxa under discussion found the oldest occurrences of their families. Geological background and structure of this Upper Triassic insect fauna of Seinstedt are shortly discussed.The questionable status of Branchiobdella tetrodonta Pierantoni, 1906 is fixed together with types is used in the correct genus. The original information was made from specimens taken out of signal crayfish obtained in Ca, United States Of America, unfortuitously, Pierantoni (1906c) didn’t designate any type specimens nor where arrangements had been deposited; they are now presumed lost. Holt (1967) believed B. tetrodonta possessed unique penial hooks and a chitinous sheath that has been as a result of his mistranslation of this original Italian description.
