List of species in the genus Lutzomyia, França, 1924 (Psychodidae, Phlebotominae) from the State of Mato Grosso

This work had the objective of listing the sand fly species that occur in the State of Mato Grosso, Brazil. Data relating to entomological surveys conducted between 1996 and 2004 were obtained from the National Health Foundation and the State Health Department, and this was supplemented with information from research carried out in the state and from the specialized literature. There were records of 106 sand fly species belonging to the genus Lutzomyia. This is a rich and diversified fauna, with some species restricted to forested areas and others recorded throughout the state, independent of the vegetation type, and in areas modified by human action, with predominance of Lutzomyia whitmani.

Biologia de Glena unipennaria unipennaria (Guenée, 1857) (Lepidoptera, Geometridae) em folhas de Eucalyptus grandis (Hill) Maiden

Este trabalho trata do estudo da biologia de Glena unipennaria unipennaria (Guenée, 1857) (Lepidoptera, Geometridae), cujas lagartas são desfolhadoras e consideradas como praga de grande importância econômica, em povoamentos homogêneos e implantados de Eucalyptus spp. (Myrtaceae), no Brasil. Os insetos foram criados em condições de laboratório (temperatura 25±3°C; UR:70±10; fotoperíodo de 12 horas), no Laboratório de Controle Biológico, do Departamento de Entomologia, da Escola Superior de Agricultura "Luiz de Queiroz"-USP, em Piracicaba, SP, em 1978. As lagartas foram alimentadas, exclusivamente, com folhas de Eucalyptus grandis (Hill) Maiden. Foram estudados os seguintes parâmetros: período e viabilidade das fases de ovo, lagarta (exceto viabilidade), pré-pupa; número e duração dos ínstares larvais e consumo foliar na fase larval; longevidade dos a dultos e proporção quanto ao sexo. Medidas lineares foram tomadas das cápsulas cefálicas das lagartas, comprimento e maior largura das pupas e envergadura das asas anteriores dos adultos. Aspectos relacionados com o comportamento e morfologia externa também foram observados.

Philander opossum (Marsupialia), a new host record for Sparganum of Lueheella Baer, 1924 (= Spirometra Mueller, 1937)

Two samples of Sparganum, the larval form of Lueheella Baer, 1924 (= Spirometra Mueller, 1937) were recovered from Philander opossum (L. 1758) captured in Salobra, Mato Grosso State, Brazil, by Dr. Lauro Travassos in may, 1942. This is the first report of the presence of this larval form in P. opossum. Dealing with helminths recovered from Brazilian Marsupialia, deposited in Oswaldo Cruz Institute Helminthological Collection, we examined in two samples of the preserved material collected in Salobra. Mato Grosso State, nine larval forms (Sparganum) of Lueheella sp. One of the samples, with six specimens, tissue. It is the first report of philander opossum harbouring this larval stage. The studied preserved wet material was stained and whole mounts were deposited in the Oswaldo Cruz institute Helminthological collection ns. 31.470 and 31.471. Measurements are in mm.

Espécie nova de Mytilopsis Conrad, 1857, do rio Tocantins, Tucuruí, Pará, Brasil: (Mollusca, Bivalvia, Dreissenidae)

A new species of Mytilopsis, mollusk bivalvi from Brazilian Amazon Region (Tocantins, Pará) is described. It is different from the American other species due small dimensions and height/width relation.

Spasskyellina mandi n. sp. (Proteocephalidea: Monticelliidae), parasite of Pimelodus ornatus Kner, 1857 (Pisces: Pimelodidae) of the Paraná River, Paraná, Brazil

Spasskyellina mandi n. sp. (Proteocephalidea: Monticelliidae) is described from the Siluriform fish Pimelodus ornatus Kner, 1857, caught in the Paraná River, Paraná, Brazil. The new species differs from other species of the same genus mainly by a fewer number of testes and by a larger osmoregulatory canal. This is the second species of proteocephalidean cestode collected in P. ornatus.
