Abstract

A female of Triatoma guazu Lent & Wygodzinsky, 1979, a rare species from which the allotype was recently described, was studied by scanning electronic microscopy and videomicroscope. Some structures of the head and the thorax are shown. Some of them could have taxonomic importance, as the oculo-ocellar region, the buccula, the anterolateral angle of the collar, the scutellum, wings and the stridulatory sulcus, which has an unusual lateral high rim

9. Triatoma vandae sp. n. do complexo oliveirai encontrada no estado de Mato Grosso, Brasil (Hemiptera: Reduviidae: Triatominae)

Abstract

There are several specific complexes belonging to the genus Triatoma Laporte, 1832, which are generally associated to specific geographic areas. Recent publications have linked the oliveirai complex to ecosystems of Mato Grosso, which are also present in other Brazilian states and even in other bordering countries as eastern Paraguay. The study of the abundant material collected during the last years allowed the description of several new species of the oliveirai complex: T. jurbergi Carcavallo, Galvão & Lent, 1998; T. baratai Carcavallo & Jurberg, 2000 and T. klugi Carcavallo, Jurberg, Lent & Galvão, 2001. Another new species belonging to the same complex is described here as T. vandae sp.n. It originates from the state of Mato Grosso, and has been reared in the insectary of the Laboratório Nacional e Internacional de Referência em Taxonomia de Triatomíneos, Departamento de Entomologia, Instituto Oswaldo Cruz-Fiocruz, Rio de Janeiro.

Abstract

Following the report of triatomine nymphs in a house in Arcadia, Miguel Pereira, state of Rio de Janeiro, Brazil, the infested dwelling was checked. Several eggs and 46 specimens of Triatoma vitticeps (Stal, 1859) were collected. Among them, adults and nymphal instars accounted for 43.5% and 56.5%, respectively. Analysis of blood meals showed the ecletism of this species; 24 (52.2%) were single feeds, 18 insects (39.1%) fed on two hosts and 4 (8.7%) on three hosts. Trypanosoma cruzi infection rate of examined specimens was 13%. Finally one of the residents of the house was positive for anti-T. cruzi antibodies using indirect immunofluorescence.

Subjects
Mepraia spinolai, Triatoma spinolai, Triatominae
Abstract

The authors revalidate the genus Mepraia, described in 1940 by Mazza, Gajardo & Jörg. The genus is monotypic and represented by the species M. spinolai (Porter, 1934). Based on the characteres described below the authors considered the separation of the genus Triatoma Laporte, 1832 and the return of the genus Mepraia. Strongly alar polymorphism, the abdomen of female with connexivum like in genus Dipetalogaster Usinger 1939, seven testicular follicles, like in Triatoma, however with a different relation of lenghts; external male genitalia showing a big and foliar process of the conjunctiva, vesica with an arch-shape, struts and endosoma process absent.

28. A new species of PseudanisakisLayman & Borovkova, 1926 (Nematoda: Ascaridida) from Rioraja agassiziiand Psammobatis extenta(Rajidae) in Brazilian southwestern Atlantic waters

Author

Santos, Cláudia, Lent, Herman, and Gibson, David

Abstract

Pseudanisakis sulamericanan. sp. is described from the intestines of the rays Rioraja agassiziiand Psammobatis extentaoff the coast of Brazil. It can be readily differentiated from the three existing species of the genus. From P. tricupolaGibson, 1973, it differs in not having cupolas on the lips, having a dentigerous ridge of 90–95 denticles (vs65–78) in a continuous subtriangular ring around the mouth, and in having an ejaculatory duct which is shorter than the spicules. From P. rajae(Yamaguti, 1941), it differs in having a single rather than a double row of denticles. It appears most similar to P. baylisiGibson, 1973, but differs from it in having a smaller body-size (7.5–27 vs16–46 mm), shorter spicules (1.14–1.90 vs1.90–3.80 mm) and especially in having much more conspicuous denticles on the lips. The present record confirms the presence of the genus in subtropical waters.
