Filogenia da tribo Attacobiini Roewer, 1955 (Araneae, Corinnidae, Corinninae)
(Universidade Federal do Pará, 2015-04-02) PEREIRA FILHO, José Moisés Batista; BONALDO, Alexandre Bragio; http://lattes.cnpq.br/8721994758453503
A cladistic analysis of tribe Attacobiini (Corinnidae, Corinninae) with 17 taxa and 109 characters is presented. The outgroup is composed by four species (Castianeira aff rubicunda ACR; Xeropigo cotijuba; Septentrinna yucatan and Falconina gracilis) all of them represented by males and females. The ingroup is represented by 13 Attacobiini species, seven of which represented by both sexes (Attacobius TOC; A. attarum; A. verhaaghi; A. lamellatus; A. uiriri; A. blakei and A. carranca), three represented only by females (A. luederwaldti; A. nigripes and A. kitae) and three represented only by males (Ecitocobius comissator; Attacobius PAR and A. tucurui). Regarding to terminals, the present data matrix represent an increase of two species in relation to a previous analysis of the Tribe. The availability of data was improved by adding character states on genitalic features for three terminals, of which the counterpart sex was unknown at the time in which that previous analysis was made (males of A. verhaagui and females of A. blakei and A. uiriri). Furthermore, several characters used in the previous analysis were re-interpreted and some new characters were proposed. A single tree was obtained under equal weights. Attacobinni and Attacobius were retrieved as monophyletic groups but the groups of species of Attacobius depicted here are considerably different from those recognized in the previous analysis. The exact solution under equal weights and all characters running unordered resulted in a fully resolved, single most parsimonious tree. As in the previous analysis, the bettersupported clades were Attacobiini and Attacobius. However, the groups of Attacobius species recovered here are considerably different from the ones recovered previously, with the exception of an apical clade composed by A. nigripes, A. kitae, A. attarum and A. luederwaldti, which was recognized in both analyses as the best supported group within the genus.

Revisão taxonômica do gênero Actinopus perty, 1833, com a descrição de quatro espécies novas de Missullena walckenaer, 1805 (Araneae, Mygalomorphae, Actinopodidae)
(Universidade Federal do Pará, 2014-03-06) MIGLIO, Laura Tavares; Pérez-Miles, Fernando; BONALDO, Alexandre Bragio; http://lattes.cnpq.br/8721994758453503
Actinopus Perty, 1833 is characterized and redescribed, harboring sixty-three species occurring from Panama to Argentina. Seventeen previously known species are redescribed: A. tarsalis Perty, 1833; A. rufipes (Lucas, 1834); A. longipalpis C. L. Koch, 1842; A. nattereri (Doleschall, 1871); A. insignis (Holmberg, 1881); A. crassipes (Keyserling, 1891); A. robustus (O. Pickard-Cambridge, 1892); A. wallacei F. O. P.- Cambridge, 1896; A. princeps Chamberlin, 1917, A. xenus Chamberlin, 1917; A. fractus Mello-Leitão, 1920; A. paranensis Mello-Leitão, 1920; A. pusillus Mello-Leitão, 1920; A. dubiomaculatus Mello-Leitão, 1923; A. trinotatus Mello-Leitão, 1938; A. cucutaensis Mello-Leitão, 1941; and A. echinus Mello-Leitão, 1949. Forty-four new species are described: Actinopus castelo n. sp., A. apalai n. sp., A. mairinquensis n. sp., A. obidos n. sp., A. buritiensis n. sp., A. pinhao n. sp., A. ducke n. sp., A. hirsutus n. sp., A. jaboticatubas n. sp., A. confusus n. sp., A. pampulha n. sp., A. candango n. sp., A. paraitinga n. sp., A. cornelli n. sp., A. vilhena n. sp., A. harveyi n. sp., A. itapitocai n. sp., A. ipioca n. sp., A. itaqui n. sp., A. xingu n. sp., A. mesa n. sp., A. caxiuana n. sp., A. utinga n. sp., A. emas n. sp., A. bocaina n. sp., A. guajara n. sp., A. apiacas n. sp., A. jamari n. sp. from Brazil; A. laventana n. sp. and A. calamuchita n. sp. from Argentina and Uruguay; A. lomalinda n. sp. from British Guiana and Colombia; A. concinnus n. sp. from Venezuela and Brazil; A. palmar n. sp. and A. loscocos n. sp. from Argentina; A. panguana n. sp. from Peru. The females of A. dubiomaculatus and A. cucutaensis and the unknown males of A. nattereri are described for the first time. New records are presented for A. crassipes; A. dubiomaculatus; A. fractus; A. nattereri; A. paranensis; A. princeps, A. pusillus, A. robustus and A. wallacei. Most of the species presently recognized were included in eleven informal groups based mainly in male palpal characters. A key for these groups plus three species, not included in any group, but known from males, is presented.

Revisão taxonômica e análise cladística do gênero Novamundoniscus Schultz, 1995 (Crustacea: Isopoda: Oniscidea)
(Universidade Federal do Pará, 2018-07-02) CARVALHO, Jonathas Teixeira Lisboa; ARAÚJO, Paula Beatriz de; http://lattes.cnpq.br/6693864880223173; BONALDO, Alexandre Bragio; http://lattes.cnpq.br/8721994758453503
Oniscidea was erected by Latreille in 1802. From Schmalfuss (1989), monophytic Oniscidea was accepted, based on derivated characters common to all Oniscidea. Dubioniscidae was erected by Schultz to include the genera Dubioniscus Vandel, 1963, Calycuoniscus Collinge, 1915 and Phalloniscus Budde-Lund, 1908 and the genus Novamundoniscus Schultz, 1995, erected to allocate the american species of Phalloniscus. This study aimed to make the taxonomic review of Novamundoniscus and to produce phylogenetic hipotesis of monophyletic relations of the species that compound this genus, based on morphology, to elaborate a phylogenetic relationship hipotesis among the genera that compounds Dubioniscidae, redescribe known species and describe new ones. This work is presented in a single chapter, divided into two parts, taxonomy and phylogeny of Novamundoniscus. 18 species of Dubioniscus, Novamundoniscus e Phalloniscus were analysed and a data matrix with 73 characters was generated. The final tree revealed Dubioniscidae as monophiletic, but, the validity of the genus Novamundoniscus could not be confirmed. The results of the phylogenetic analyses presented herein are considered provisory and, the taxonomic implications of the topology discussed were not adopted in the taxonomic revision of Novamundoniscus. However, the optimizations of the characters in this topology furnishes important conclusions for the understanding of the evolutive history of the taxa analysed and the characters matrix offers a solid basis for the continuation of this line of research.
