Lopesiodinia alvarengai Prado, 1973 (Odiniidae: Traginopinae) with the first description of the male and the neotype designation.

The type specimen of Lopesiodinia alvarengai Prado is lost. It is being redescribed and illustrated based on specimens from the type locality (Jacareacanga, Par, Brazil) and the neotype is here designated with the purpose of clarifying the taxonomic status and objectively securing stability of nomenclature.

Mantodea (Insecta) in the Invertebrate Collection of Instituto Nacional de Pesquisas da Amaznia (INPA), Manaus, Brazil.

Increasingly, scientific collections play a fundamental role in the conservation and analysis of biodiversity as a witness and repository of ecosystem organisms at risk of losing their species. The Invertebrate Collection of the Instituto Nacional de Pesquisas da Amaznia (INPA) safeguards biological information, mainly from the Amazon biome, one of the most diverse and threatened ecosystems on the planet. Mantodea specimens deposited dry in the INPA Collection were reviewed. A total of 2,721 specimens were found deposited until the year 2019. A total of 194 species and 81 genera were found with representatives of all the neotropical and several "Old-World" families. Families such as Mantidae, Photinaidae, and Thespidae represented the highest percentages of specimens collected within the sample, with 30%, 11%, and 9%, respectively. Four genera and fourteen species are recorded for the first time for Brazil, bringing the number of species to 247. This officially makes Brazil the most diverse country in terms of Mantodea fauna on the planet. The Collection stands out for being the most diverse reported in Latin America, even with several species yet to be described. Presently it has seven primary type specimens and 26 secondary type specimens. The excellent state of conservation of the specimens, the number of specimens, and the diversity represented have made the INPA Collection an international benchmark for Amazonian and Neotropical studies on Mantodea.

Insect (Hexapoda) Diversity in the Oceanic Archipelago of Fernando de Noronha, Brazil: Clusiidae (Diptera).

For the first time, Clusiidae (Diptera) species are recorded from the oceanic Archipelago Fernando de Noronha, Brazil. They are represented by three genera and seven species: Czernyola fumialula sp. nov., Heteromeringia czernyi Kertsz, 1903, Sobarocephala araujoi sp. nov., S. finnilaei Frey, 1918, S. icmbio sp. nov., S. protea Lonsdale & Marshall, 2012, and S. sp. For S. icmbio sp. nov., the aggregation behavior at night was observed on the undersides of broad leaves, females contained an average of 71 eggs, and flight interception traps correlated a positive linear relationship with precipitation seasonally. An illustrated key is presented for all species of the Archipelago.

Description of the female of Copestylum tigrinum Ricarte amp; Hancock in Ricarte et al., 2015 (Diptera, Syrphidae), first record in mainland South America and new larval host plant.

Larvae of Copestylum tigrinum Ricarte Hancock in Ricarte et al. 2015 were reared from fallen fruits of Casearia combaymensis Tul. (Salicaceae) collected in the Brazilian Amazon (Amazonas, Brazil). This is the first record of this species in mainland South America and Brazil, and the first record of a fruit of Salicaceae as a food substrate for the larvae of C. tigrinum. The female and its genitalia are described for the first time, the puparium is redescribed and some aspects of the biology of Copestylum are discussed.

Taxonomic review of the millipede genus Haematotropis Jeekel, 2000 (Diplopoda, Polydesmida, Aphelidesmidae, Aphelidesminae) with descriptions of thirteen new species.

The northern South American genus Haematotropis Jeekel, 2000 is shown to presently encompass 21 species, all duly redescribed, illustrated, keyed, and mapped, including 13 new species: H. amazonica sp. nov. (Amazonas, Brazil), H. aripuanensis sp. nov. (Mato Grosso, Brazil), H. callyi sp. nov. (French Guiana), H. dentata sp. nov. (Maranho, Brazil), H. disjunctoides sp. nov. (Par, Brazil), H. goeldii sp. nov. (Par, Brazil), H. jurutiensis sp. nov. (Par, Brazil), H. driki sp. nov. (Amazonas, Brazil), H. melgacensis sp. nov. (Par, Brazil), H. mosaica sp. nov. (Par, Brazil), H. paraensis sp. nov. (Par, Brazil), H. poranga sp. nov. (Par, Brazil) and H. tysoni sp. nov. (Amazonas, Brazil). New characters are used in all descriptions and redescriptions. Aphelidesmus guianensis Chamberlin, 1923, the type species of Ochrotropis Jeekel, 2000, is a new junior synonym of Aphelidesmus divergens Chamberlin, 1918, comb. nov. ex Ochrotropis in Haematotropis.

Revision of the genus Lopesiodinia Prado, 1973 (Diptera: Odiniidae) with description of three new species, and a key to the extant Neotropical genera and species of Traginopinae.

The Neotropical genus Lopesiodinia Prado is represented by two species, L. diversa Prado (Brazil: Rio de Janeiro) and L. alvarengai Prado (Brazil: Par). The genus is reviewed here, and three new species are described and illustrated: Lopesiodinia marcusi sp. nov. (Brazil: Amazonas, Maranho), L. argentata sp. nov. (Brazil: Amazonas) and L. pontarolloi sp. nov. (Brazil: Amazonas, Maranho). A key to identify the subfamilies and extant genera and the species of Traginopinae from the Neotropical Region is presented.
