Description of the Pupa and Redescription of the Imagines of Geyeria decussata and their Association with Bromeliads in Southern Brazil (Lepidoptera: Castniidae)

ALBERTONI F F [Fed Univ, Florianopolis, Brazil], MORAES S S [Mus Zool USP, Sao Paulo, Brazil], STEINER J [Fed Univ. Florianopolis, Brazil] & ZILLIKENS A [Univ Tubingen, Germany]: Description of the Pupa and Redescription of the Imagines of Geyeria decussata and their Association with Bromeliads in Southern Brazil (Lepidoptera: Castniidae). - Entomol Gener 34 (1-2): 061-074: Stuttgart 2012-09. - [Article] Bromeliads can serve as a resource for numerous arthropods, especially insects. Caterpillars of the moth Geyeria decussata (Godart 1824) were recorded in the leaf rosettes of the bromeliads Wittrockia superba, Vriesea philippocoburgii and Aechmea nudicaulis. The larvae were feeding on the leaf bases, eventually killing the plants. In addition to life history data a description of the pupa and a re-description of the imagines are provided here. These findings constitute new records of larval hosts for this species and confirm a close association of castniid moths and bromeliads.

The cascudos of the genus Hypostomus Lacépède (Ostariophysi: Loricariidae) from the rio Iguaçu basin

We reviewed several large collections of the genus Hypostomus from the rio Iguaçu basin summing up to 793 specimens mainly from the Laboratório de Ictiologia do Departamento de Ecologia e Biologia Evolutiva from Universidade Federal de São Carlos, from fish collection of Núcleo de Pesquisas em Limnologia, Ictiologia e Aquicultura da Universidade Estadual de Maringá, and from the Museu de História Natural do Capão da Imbuia. Hypostomus albopunctatus, H. commersoni, H. derbyi, and H. myersi are redescribed and Hypostomus nigropunctatus is described as a new species. A practical key for identification of Hypostomus species from the rio Iguaçu is also provided.
