- Checklist and identification key to Brazilian species of Triplocania Roesler (Psocodea: ‘Psocoptera’: Psocomorpha: Ptiloneuridae), with four new cave-dwelling species(Magnolia Press, 2021-03-03) SILVA NETO, ALBERTO MOREIRA DA; GARCÍA ALDRETE, ALFONSO N.; RAFAEL, JOSÉ ALBERTINO; FERREIRA, RODRIGO LOPESFour species of Triplocania are described and illustrated (T.brancoin. sp., T.ferratilisn. sp., T. painsn. sp., and T. zairaen. sp.), all based on male specimens collected in caves of the Brazilian state of Minas Gerais. An identification key is presented to the Brazilian species of Triplocania, based on males, together with information on both sexes and distributions.
- Three new cave-dwelling Eukoenenia (Palpigradi: Eukoeneniidae) from limestone caves in Northern Minas Gerais state, Brazil(Magnolia Press, 2020-07-02) SOUZA, MAYSA FERNANDA VILLELA REZENDE; FERREIRA, RODRIGO LOPESIn this paper, we describe three new Eukoenenia species from specimens collected in limestone caves in the northern region of the Minas Gerais state, Brazil. These species present different degrees of adaptation to the subterranean habitat, with Eukoenenia magnasp. nov., with 6 blades on lateral organs and body ratios very close to other troglobitic species, being the most troglomorphic among them. This species is morphologically very similar to the Brazilian troglobites E. navi, E. eywa and E. neytiri. Eukoenenia lundisp. nov. and Eukoenenia jequitaisp. nov. are probably closely related species due to their substantial morphological resemblance. These two species are closer to E. virgemdalapa among the Brazilian species described to date. We provide a table summarizing the main diagnostic characters of the three species herein described and those of the Brazilian congeners to facilitate morphological comparisons.
- New troglobitic and troglophilic syntopic species of Endecous(Orthoptera, Grylloidea, Phalangopsidae) from a Brazilian cave: a case of sympatric speciation?(Magnolia Press, 2020) CASTRO-SOUZA, RODRIGO ANTÔNIO; ZEFA, EDISON; LOPES FERREIRA, RODRIGOCrickets of the genus Endecous (Orthoptera: Grylloidea: Phalangopsidae) are frequently found in caves, in some cases presenting strictly subterranean lifestyle. In addition to the morphological diagnostic characters of the group, bioacoustic and karyotype, also help on delimiting species. Here, we describe two new sympatric species of this genus, which occur in the largest cave of Minas Gerais state, Brazil, using the morphology of phallic complex, the courtship song and karyotype. Moreover, we discuss the criteria used, the troglomorphisms for this genus, as well as hypothesis on the speciation process involving these species.
