Skrjabinoclava tupacincai Freitas, Vicente & Ibáñez, 1970 in Brazil and some other helminths from tyrannidae birds

Brief comments are made on five species of nematodes: Skrjabinoclava tupacincai Freitas, Vicente & Ibáñez, 1970, Deliria gomesae Vicente, Pinto & Noronha, 1980, Ornithofilaria pitangi Vicente, Pinto & Noronha, 1980, Diplotriaena delirae Pinto & Noronha, 1970, Thelazia sp.; three species of trematodes: Lutztrema transversum (Travassos, 1917) Travassos, 1941, Lophosicyadiplostomum nephrocystis (Lutz, 1928) Dubois, 1937, Gynaecotyla jägerskiöldi (Travassos, 1920) Yamaguti, 1939; one species of cestode: Biuterina campanulata (Rudolphi, 1819) and one species of acanthocephala: Centrorhynchus opimus Travassos, 1921, that were studied in order to provide some data concerning the examined samples.

Redescription of the type-material of creptotrema creptotrema travassos, Artigas & Pereira, 1928 (Digenea, Allocreadiidae)

Creptotrema creptotrema Travassos, Artigas & Pereira, 1928, a digenetic trematode parasite of Leporinus elongatus, is redescribed from the type-material with additional morphological data and original figures.

Redescription of Teratotrema dubium, Travassos, Artigas & Pereira, 1928 (Callodistomidae: Digenea)

Teratotrema dubium Travassos, Artigas & Pereira, 1928, a digenetic trematode parasite of Pseudocurimata plumbea (Curimatidae: Pisces) is redescribed with additional morphological data, confirming the presence of a single testis.

Culex saltanensis Dyar, 1928: natural vector of Plasmodium juxtanucleare in Rio de Janeiro, Brazil

Searching for the natural vector of Plasmodium juxtanucleare in an enzootic locality: Granjas Calábria (33% of the chickens infected), Jacarepaguá, in Rio de Janeiro, Brazil, 13 comparative captures of mosquitoes were carried out, simultaneously on man (out-doors) and on chiken (in a poultry-yard), between 6 and 9 p.m., from September to March 1989. Culex saltanensis was the most frequent species in captures on chicken, accounting for 41.7% of the mosquitoes collected on this bait, showing to be highly ornithophilic (90% captured on chicken versus 10% on man). Seven specimens of Cx. saltanensis were found naturally infected in granjas Calábria: five with mature pedunculate oocysts and two with sporozoites (on in the haemocoele and one in the salivary glands). These sporozoites porudced an infection by P. juxtanucleare in a chick, which had parasitemia on day 41 after inoculation. One Cx. coronator was found with mature pedunculate oocysts. Culex saltanensis was regarded as primary vector of P. juxtanucleare in Rio de Janeiro for being highly ornithophilic and in enough density to maintain the transmission, having been found with infective sporozoites in its salivary glands, and being susceptible to the parasite and able to transmit experimentally it by the bite.

Crithidia ricardoi sp. n. a new species of trypanosomatidae isolated from Culex saltanensis Dyar, 1928 (Diptera: Culicidae)

A flagellte trypanosomatid was isolated in culture from the digestive tract of the mosquito Culex saltanensis Dyar, 1928. It grows exuberantly in liver infusion in the form of epimastigotes and choanomastigotes typical of the genus Crithidia. The trypanosomatid was compared to C. deanei, C. fasciculata, C. luciliae, C. oncopelti and C. guilhermei. The techniques used for comparison were electron transmission microscopy, isoenzymes and kDNA restriction profiles. No endosymbionts were found at electron microscopy. Results for the biochemical methods employd indicate that the trypanosomatid isolated from C. saltanensis is a new species of Crithidia. The name C. ricardoi sp. n. is proposed for thes new species.
