Nine new species of the water scavenger beetle genus Oocyclus Sharp, 1882 are described from the Brazilian Shield: O. ecolab sp. n., O. espinhacu sp. n., O. giganteus sp. n., O. humboldti sp. n., O. lacia sp. n., O. ovalis sp. n., O. sulcatus sp. n., O. thrixdiastematus sp. n., and O. thysanus sp. n. New locality records are provided for four species previously known from Brazil: O. rotundus Clarkson & Short, 2012, O. pilosus Jordão, Clarkon & Ferreira-Jr, 2018, O. xanthus Clarkson & Short, 2012 and O. yubai Clarkson & Short, 2012. All species are associated with rock-face seepages such as wet rocks, waterfalls, and seepages. An updated key to the Brazilian species of Oocyclus is provided.

Abstract— Praxelis scaturicola, a new Cerrado biome species, is described and illustrated. The main morphological features of this new species are: i) capitula usually isolated; ii) vinaceous involucral bracts; iii) reduced glabrous leaves well-spaced on the stem. This study also presents information on aspects of the new species’ habitat, as well as field images and illustrations. Praxelis scaturicola is known only from the Paraúna municipality in Goiás state, Brazil. A key and comments on the Brazilian species of Praxelis are also presented with a special note on the status of P. grandiflora. Additionally, the synonymy of P. macrocarpa under P. capillaris is proposed.

The Brazilian standard ABNT NBR 7190 (1997) governs the premises for the wood structure sizing through a table and the simplified method. Thus, this research aims to analyze whether the simplified method shown in the standard matches the resistance values of 72Brazilian species, separated from class C20 to C60. In the end, it was possible to conclude that the value displayed by the standard between theratio of shear and compressionin thedirection parallel to the fibers is half of what actually happens in Brazilian species, showing anurgent review in the standard premises.

We increase the knowledge on the taxonomy of Brazilian Syneches describing 10 new species: S. amorimi sp. nov., S. barrettoi sp. nov., S. digitatus sp. nov., S. fasciatus sp. nov., S. flaviscutellatus sp. nov., S. fuscus sp. nov., S. nordestino sp. nov., S. plaumanni sp. nov., S. sinclairi sp. nov., and S. smithi sp. nov., and redescribing three species: S. catarinae Smith, 1962, S. luteus (Wiedemann, 1830) and S. tomentosus Smith, 1962. Syneches ruficollis (Walker, 1852) is proposed as a nomen dubium since the type is lost and the original description does not allow identification. An identification key, high-resolution images of relevant characters, short diagnoses and maps of geographic records for all 34 Brazilian species now included in the genus are provided, as well as a checklist for the South American species of Syneches.

In this paper, we presented additional information to the description of Cheletomimus (Hemicheyletia) wellsi (Baker, 1949) (Acari: Cheyletidae) collected on Vitis vinifera L. (Vitaceae), Ruellia angustiflora (Ness) Lindau ex Rambo (Acanthaceae) from Dois Lajeados, Marques de Souza and Pantano Grande municipalities in Rio Grande do Sul state, and on Malus domestica Borkh (Rosaceae) in Campo do Tenente municipality, Paraná state, Brazil. The specimens examined presented intraspecific variations from those described previously. These variations will be discussed herein. A key to the known Brazilian species of the genus is provided.

This study concerns the diplopod genus Eucampesmella Schubart, 1955, widespread in Brazil. After this work, the genus includes 12 valid species, and three incertae sedis: E. pugiuncula (Schubart, 1946), E. brunnea Kraus, 1959 and E. schubarti Kraus, 1957. The type-species, Eucampesmella tricuspis (Attems, 1931), is redescribed based on the holotype, and the following six new Brazilian species are added: Eucampesmella macunaima sp. nov. from the states of Rondônia, Pará, and Piauí; E. capitu sp. nov. from the states of Piauí and Paraíba; E. brascubas sp. nov. from the state of Sergipe; E. iracema sp. nov. from the state of Pernambuco; E. pedrobala sp. nov. from the state of Ceará; and E. lalla sp. nov. from the state of Rio Grande do Norte. Furthermore, E. lartiguei ferrii (Schubart, 1956) is recognized as a junior synonym of E. lartiguei lartiguei (Silvestri, 1897), which also had its status changed, and E. sulcata (Attems, 1898) is revalidated, prevailing under the name Leptodesmus tuberculiporus Attems, 1898. In addition, drawings, diagnoses, and distribution maps for all species of the genus are provided.

Anaulacomera currently contains 147 valid species, of those 50 are recorded from Brazil. The genus is further divided into six subgenera, which can be distinguished on characteristics of the male terminalia. A new Brazilian species is presently proposed, Anaulacomera (Anallomes) curvata sp. nov., based on three males and one female collected at Parque Nacional de Itatiaia, Itatiaia, Rio de Janeiro State. It can be distinguished from all other species because of the pair of cerciform projections of the tenth male abdominal tergite and a combination of shape and size of the male cerci.
