A case of mosquito heavily parasitized by water Mite larvae
One female of Culex fatigans Wied., 1828, was collected in a light trap at CENA-ESA«LQ»-USP, Piracicaba, at about 500 meters off the Piracicaba River banks. This mosquito exhibited 15 partially engorged pionid larvae of water mites (Prostigmata, Hydrachnellae) of the genus Arrenurus, attached to the articular membranes of the abdominal segments; no mites were found on the thorax or coxae. The larva is drawn, dorsad and ventrad. Since species cannot be identified from larvae, no specific name is given
Nota sobre ĂĄcaros (Acari) atacando fruteira-do-conde (Rollinia sp.)
The flowers of this orchard tree presents six fleshy petals, fused two by two, and disposed propeller like. In the center is a cavity which harbors the cone shaped reproductive organs. An eriophyid mite, described by H. H. Keifer as Aculops flechtmann Keifer, 1972, causes considerable bronzing to the petals (Fig. 1-A). Large numbers of this mite attacking the basis of the reproductive organs causes them to dry and drop. On the young fruits, which are squamous, this mite causes some rusting and small necrotic areas (Fig. 1-B). As the fruit grows these small areas remain dark and barky. Very often the necrotic areas are invaded by the false spider mite Brevipalpus phoenicis (Geijskes, 1939), which enlarges the damage. The false spider mite also attacks leaves and green stems; the epidermis of the latter then assumes a barky appearance

CatĂĄlogo TaxonĂŽmico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil
The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the CatĂĄlogo TaxonĂŽmico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

Relation to host. Vagrants on inner surface of leaves causing no apparent damage. Etymology. The specific designation spinula, from the Latin, feminine, diminutive spina, thorn, refers to the short, spinelike scapular seta. Remarks.

It shares the general aspect of the epigynum with N. vasquezae Navia & Flechtmann 2003, but differs in the frontal lobe of the prodorsal shield (acuminate in N. spinula n. sp., rounded in N. vasquezae), in the scapular seta (very short, spinelike in N. spinula n. sp.; long, setiform in N. vasquezae) and in the number of dorsoÂopisthosomal annuli (26 in N. spinula n. sp., 48 in N. vasquezae).

Querino, on 2 microscopic preparations, in the collection of LaboratĂłrio de Quarentena Vegetal, Embrapa Recursos GenĂ©ticos e Biotecnologia, Brasilia, DF, Brazil and paratypes in the collection of Departamento de Entomologia, Fitopatologia e Zoologia AgrĂcola, Universidade de SĂŁo Paulo, ESALQ, Piracicaba, SĂŁo Paulo, Brazil. Relation to host. Mites are vagrants on inner surface of leaves causing no apparent damage. Colonies were observed protected under a dense layer of loose trichomes along the midrib. Etymology. This species is named after Ranyse Querino Barbosa, Entomologist at Unimontes, Montes Claros, Minas Gerais, Brazil, in appreciation of her inestimable help in collecting this material. Remarks. Palmiphytoptus barbosae n. sp. is the second species described in this genus. It differs from the type species, P. oculatus Navia & Flechtmann 2002, in the fusiform body shape (elongate, vermiform in the type species), in presenting median and admedian lines on the prodorsal shield (central shield area not ornamented in P. oculatus); in the absence of eyeÂlike structures (present in P. oculatus) and in smooth dorsoopisthosomal annuli (microtuberculated in P. oculatus). Inadvertently Amrine et al. (2003, p. 18) included the eye like structures, a specific character of the type species, as a generic character for Palmiphytoptus, in the key to genera.

Barbosa, on 2 microscopic preparations, in the collection of LaboratĂłrio de Quarentena Vegetal, Embrapa Recursos GenĂ©ticos e Biotecnologia, Brasilia, DF, Brazil and paratypes in the collection of Departamento de Entomologia, Fitopatologia e Zoologia AgrĂcola, Universidade de SĂŁo Paulo, ESALQ, Piracicaba, SĂŁo Paulo, Brazil. Relation to host. Mites are vagrants on inner surface of leaves, along midribs, causing no apparent damage. Etymology. The specific designation alternatus, from the Latin, alternating, refers to the alternating shorter and longer lateral expansions of the dorsal opisthosomal annuli. Remarks. Propilus alternatus n. sp. is distinct in presenting alternating short and long lateral projections on the dorso opisthosoma annuli. In other described species these projections are of uniform size, either with or without prominent spines.Published as part of Navia, Denise & Flechtmann, Carlos H.
