ABSTRACT A new material collected and the holotype of Entoloma azureoviride were studied. The analysis of these specimens showed some discrepancies with the protologue which are discussed here. The diagnostic characters of this species are the following: fibrillose pileus, blue lamellae, cuboid spores, and abundant oleiferous hyphae in the lamellae trama. It was also observed a peculiar pseudoparenchymatous pileus trama consisting of inflated elements up to 25 µm in diam., that become more elongated towards the hymenium. A comparison of E. azureoviride with other species with blue tints in the subgenus Inocephalus and a discussion about its morphological peculiarity are provided.

A new genus and five new species of odiniids (Odiniidae: Traginopinae) are described from the Brazilian Amazon and Cerrado biomes: Inpauema mirador gen. nov. et sp. nov. (type species), I. catarinae sp. nov., I. gaimarii sp. nov., I. raimundoluizi sp. nov., and I. xavieri sp. nov. The genus is being characterized by a unique combination of diagnostic characters: body predominantly dark brown to black, with silvery-gray pruinose spots on inner margin of eyes, longitudinally along middle of lunule and face, on notopleuron and mesopleuron; postcranium concave from dorsal view; one pair of stout proclinate ocellar setae; postocellar setae absent; lunule shorter than frons; gena lacking upturned seta; antennae separated by a maximum distance of 2X the diameter of a single antennal socket and gonocoxal apodemes directed upward, forming an arch. A key to separate Helgreelia Gaimari, 2007 from Inpauema gen. nov. and for the new species is provided.

Herein one new species of Amazhomidia Cipola & Bellini from Brazilian Amazon is described and illustrated: A. thaisae sp. nov., plus one specimen no nominal due to lack of material for formal descriptionend point.  Acanthocyrtus guianiensis Womersley is redescribed and transferred to Amazhomidia by presence of prelabral chaetae bifurcated, macrochaetotaxy pattern, manubrium laterally with long distal mac finely ciliate and dens ventrally unscaled. Acanthocyrtus croceus Womersley is confirmed as a junior synonymy of A. guianiensis. The juvenile description of Amazhomidia ducke is provided, and changes in chaetotaxy nomenclature are made based on them. Acanthocyrtus lineatus Womersley is redescribed based on type material and new diagnostic characters are revealed. Identification keys for both genera and a comparison for Entomobryinae genera with dental spines are provided. Amazhomidia has now three and Acanthocyrtus Handschin six valid species.

Abstract In this study, supplementary information on the morphology of the siphonostomatoid copepod Lepeophtheirus acutus Heller, 1865 is given based on new material collected from the ventral body surface and mouth cavity of common guitarfish, Rhinobatos rhinobatos (Linnaeus) and from the branchial cavity of bull ray, Aetomylaeus bovinus (Geoffroy Saint-Hilaire) caught in Iskenderun Bay, Turkey. This is the first report of L. acutus from Mediterranean waters. Key diagnostic characters of both sexes are reported, supported by light and scanning electron microscopy observations. In addition, Lepeophtheirus rhinobati Luque, Chaves et Cezar, 1998, which is closely related to L. acutus and has been reported from the same host genus, Rhinobatos, is reexamined based on paratypes stored in the collections of the United States National Museum of Natural History. Some of the key diagnostic characters which were incompletely known or lacking in the original description of both sexes of L. rhinobati are redescribed and/or presented for the first time.

Generic Family

One of the objects of zoological study is to ascertain more completely and more accurately the peculiarities by which one kind of animal (species, variety, genus, &c.) is distinguished from another. The advance of our knowledge in this direction depends on the more minute examination and more accurate distinction of known forms, the examination of larger numbers of specimens from familiar localities, and the examination of specimens from localities previously unsearched. There is scarcely any family so thoroughly investigated that it does not yield new discoveries on a renewed examination of more abundant material. It is found possible to recognise finer distinctions, and so split up one species into several, or convert what was considered a species into a genus. New material—that is to say, examination of a large number of specimens— often shows, too, that distinct species are more or less connected by intermediate forms. But in all this work the part played by these minute peculiarities in the life of the animal usually receives little attention. It is not the object of systematic zoology to ascertain the uses of characters, or to explain their origin. These objects require different methods, and are usually pursued by different investigators. But among the various methods employed there is one which has seldom, if ever, been followed—that of surveying the various characters of different grades,—specific, generic, family, &c.—in order to find whether it is possible to trace a connection between them and the habits of the animals which exhibit them, and generally to consider how far the principles which have been suggested in explanation of the evolution of species are applicable to the diagnostic characters of a particular family.

The Western Region

Passalus Fabricius, 1792 is the largest genus of Passalidae and presents great diversity in South America, mainly in the Amazon region. Currently this complex and heterogeneous genus is subdivided into three subgenera: P. (Pertinax) Kaup, 1869, P. (Mitrorhinus) Kaup, 1871, and P. (Passalus). Herein, two new species of Passalus from the western region of the Brazilian Amazon, a diverse but poorly studied area, are described and illustrated. The new species Passalus (Pertinax) deuterocerus sp. nov. and Passalus (Passalus) cleidecostae sp. nov. are compared with similar species occurring in nearby regions. Also, the diagnostic characters used to define the subgenera and sections of Passalus are summarized.

Three species of Pleuranthodium were encountered and collected during a survey of gingers at Mount Wilhelm, Chimbu Province, Papua New Guinea. Based on new material, the only previously known Pleuranthodium from this area, P. piundaundense, is described in more detail highlighting new diagnostic characters and its known distribution range is expanded based on identification of older specimens at Edinburgh from two other provinces. Two species so far only known from Mount Wilhelm could not be identified after studying all protologues, types and material from several herbaria. These are here described as new species, P. corniculatum and P. sagittatum. A key with both floral and vegetative characters is provided to all three species. Pleuranthodium corniculatum is distinct in having apical appendages on the calyx, and P. sagittatum has a wrinkled calyx. All species are described and illustrated, and conservation assessments are made.

Basing on the examination of new material on many-plumed moths from Tanzania, four new species have been discovered: Alucita agassizi Ustjuzhanin & Kovtunovich sp. nov., A. iringiensis Ustjuzhanin & Kovtunovich sp. nov., A. snezhinka Ustjuzhanin & Kovtunovich sp. nov. and A. tanzanica Ustjuzhanin & Kovtunovich sp. nov. They are described and compared with the closest species. The diagnostic characters for each new taxon are specified. The genitalia are described and illustrated, images of the adults are provided. Data on many-plumed moths previously unknown for Tanzania are given. Two species, A. seychellensis (Fletcher 1910) and A. malawica (Ustjuzhanin & Kovtunovich, 2016) are reported from Tanzania for the first time.

Two New Species

Two new Podischnus Burmeister, 1847 species are described here: Podischnus limeirai sp. nov. from Gurupi region, Maranhão state, Brazil, the easternmost distribution of the genus; and Podischnus cleidecostae sp. nov. from the Acre state, Western of Brazilian Amazon Forest. New diagnostic characters are illustrated and discussed for the genus. An illustrated identification key for all Podischnus species, and an up-to-date distribution map for the Brazilian species of Podischnus are provided. Moreover, we propose the inclusion of P. limeirai sp. nov. in the Red List of Threatened Species (IUCN) due to the fast loss of the Oriental Amazon Forest remnant fragment in that region.
