Larval stages of Pyromaia tuberculata (Lockington, 1877) (Decapoda, Majidae, Inachinae) reared in the laboratory

The larval development of Pyromaia tuberculata (Lockington, 1877) is described from specimens reared in the laboratory. Larvae were obtained from ovigerous females collected by trawl in Ubatuba, São Paulo state, Brazil. Rearing was carried out at 24 +/- 1 degrees C in 35 parts per thousand S. The larvae pass through two zoeal stages before moulting to the megalopa. A comparison is made with previously studied majid species occurring in the southern and southeastern regions of Brazil.

A new species of Pterodectes Robin, 1877 (Proctophyllodidae: Pterodectinae) from the pale-breasted thrush, Turdus leucomelas (Passeriformes: Turdidae)

A new species of feather mite, Pterodectes fissuratus sp. n., is described from the pale-breasted thrush, Turdus leucomelas Veillot (Passeriformes: Turdidae), in Brazil. This species is easily distinguished by having numerous well-pronounced lacunae and a longitudinal median furrow on prodorsal and hysteronotal shields in both sexes. Copyright © 2005 Magnolia Press.

Sedenions of Cayley-Dickson and the Cauchy-Riemann like relations

This work is an extension to sedenions of the Cauchy-Riemann relations, following a similar earlier construction made by one of the authors (M. Borges) to quaternions and octonions, see [1], [2], [3]. © 2011 Academic Publications.
