A New Species

AbstractA new species of the genus Diomedenema, a spiruromorph nematode, collected from the lung of Spheniscus magellanicus (Sphenisciformes) found on the southern coast of the state of Rio Grande do Sul, Brazil, is described. The new species is differentiated from the only previously described species of the genus, D. diomedeae Johston & Mawson, 1952, by males possessing a set of caudal papillae with three pairs of precloacal, two pairs of adcloacal and one pair of postcloacal papillae; precloacal papillae with the papillae of the first two pairs being closer to each other than those of the third pair; a longer and pointed tail in males; and females with the vulva at mid-body. This is the first report of a nematode infecting the lung of a sphenisciforme host.

A New Species

(A new species of Graphis [Graphidaceae: Lichenized Ascomycota] and a revised key of the genus in Rio Grande do Sul, southern Brazil). In this paper we describe a new species of the lichen genus Graphis, namely G. suzanae Koch & Feuerstein. This species is characterized mainly by lirellae with entire labia, a partially exposed disc with orange pigment in the epithecium, a lateral thalline margin, a laterally carbonized excipulum, a clear hymenium, and transversely septate ascospores measuring 40–44 × 8–10 μm. The chemistry of the species was assessed through TLC analysis. A complete key with G. suzanae and 56 more species of Graphis that where previously recorded to the state of Rio Grande do Sul, southern Brazil, is included.

A New Species

AbstractA new species of Cacatuocotyle is described from the external surface of Astyanax aff. fasciatus and Astyanax jacuhiensis from Lake Guaíba, State of Rio Grande do Sul, Brazil. It differs from the other three species of the genus, recorded from Mexico and the State of Paraná, Brazil, by possessing an accessory piece with a long proximal portion, a U-shaped bar with irregular posterior margin in its midportion, and a haptor containing two circular thickenings with muscular anterior margins. Only one monogenean species, Urocleidoides astyanacis (= Characithecium costaricensis) was recorded for the host Astyanax aff. fasciatus, whereas none were known for A. jacuhiensis. This paper records a new host (A. jacuhiensis) for monogeneans in southern Brazil and extends southward with the geographical distribution of the genus Cacatuocotyle to the State of Rio Grande do Sul, Brazil.

Eleven Species

The genus Caponina Simon, 1891 comprises eleven species of medium-sized, soil-dwelling caponiids. Most members of Caponina have six eyes, but some have five, four, three or two eyes (Brignoli 1977, Platnick 1994). The genus is widespread in South and Central America (Platnick 2012). To date, only three species have been recorded from Brazil: Caponina alegre Platnick, 1994 from the state of Rio Grande do Sul, C. notabilis (Mello-Leitão, 1939) from the states of Paraná and Rio Grande do Sul, and C. tijuca Platnick, 1994 from the state of Rio de Janeiro (Platnick 1994). In this paper we describe a new species from the state of Pará, in Brazilian Amazonia. Caponina papamanga new species was collected during the “Butantan na Amazonia” project, founded by the Instituto Butantan. The phylogenetic relationships of C. papamanga could not be studied, but the greatly elongated embolus, the dorsal tubercle on the palpal femur (Figs. 7, 9) and the massive epigynal sclerotizations (Fig. 10) suggest that this species belongs to the monophyletic Andean group proposed by Platnick (1994: 7).
