| A pictorial field guide to the 30 species of sandfly most commonly encountered in Pará State is presented, based on the easily recognised external characters of the length of the 5th palpal segment, thoracic infuscation, abdominal colour and head and body size. In most cases this allows identification to the species. In others, especially with females, it gives an indication of the species, which may then be confirmed with data from more detailed taxanomix studies. This type of field guide helps in teaching, rapid sorting of flies prior to dissection and in acquainting visitors with the variety of species present in a given area.A rapid technique for the taxonomic sorting of unmounted, freshly killed female sandflies is required, prior to the dissection of... |

| ABSTRACT The preliminary results are given of studies on the sandfly fauna (Diptera: Psychodidae) in forest surrounding the Humboldt Research Centre, Municipio of Aripuanã, Mato Grosso State, Brazil. A total of 712 sandflies were obtained, including 26 different species: of these, 387 were caught off human bait; 317 from tree-trunks; 4 in a malaise-trap; 3 in rodent baited oil traps; and 1 in a light-trap. Man-biting species were absent or very rare during studies in the dry season (August and September, 1974), but relatively abundant at the end of the rainy season (June, 1975): this suggests a seasonal transmission of leishmaniasis. The species at present known as Lutzomyia anduzei of Floch & Abonnenc (1942) was a major man-biter, this species is an... |

| Abstract A leishmanial parasite was isolated from 11 of 18 porcupines from the general area of Ponta de Pedras, Island of Marajó, Pará State, north Brazil. Two of the infected animals were identified as Coendou prehensilis (Linnaeus), and the other 9 are considered as a hitherto undescribed species of Coendou. The organism is clearly related to L. hertigi Herrer, of the Panamanian porcupine C. rothschildi Thomas, but morphological, serological and biochemical differences necessitate taxonomic distinction. The Brazilian parasite is therefore named Leishmania hertigi deanei nov. subsp., in honour of Dr. Leonidas Deane who first recorded it in porcupines from Piaui, Brazil. Lake L. h. hertigi, L. h. deanei produces no visible pathological effects in its... |
