Brazilian scientists have described a new species of annual killifish from southern Brazil in a recent issue of the journal Neotropical Ichthyology.

Julian Ferrer, Luiz Malabarba and Wilson Costa describe Austrolebias paucisquama from the laguna dos Patos drainage, distinguishing it from congeners in having a combination of: dark grey pectoral fins, bright blue iridescence in males, 12 scales around the caudal peduncle, 17"21 dorsal-fin rays in males, lack of contact organs on the inner surface of the pectoral fin in males and light brownish females with a variable number of large black spots mostly on the posterior portion of the body.

Austrolebias paucisquamis was collected from a temporary pool and is named after the relatively few scales around the caudal peduncle (Latin paucus=few and squama=scale).

For more information, see the paper: Ferrer, J, LR Malabarba, WJEM Costa (2008) Austrolebias paucisquama (Cyprinodontiformes: Rivulidae), a new species of annual killifish from southern Brazil. Neotoprical Ichthyology 6, pp. 175"180.
