Abstract: the phlebotomine sand flies nyssomyia intermedia (lutz & neiva, 1912) and nyssomyia neivai (pinto, 1926) are very close and may be involved in the transmission of leishmania spp. ross, 1903 in brazil. the biology of the first laboratory-reared generations of these species, descended from insects captured in além paraíba (n. intermedia) and corinto (n. neivai) in the brazilian state of minas gerais, is described here. the captured females were fed on hamsters and maintained individually in rearing pots. laboratory temperature and relative humidity were maintained at 25-26oc and 80% respectively. the productivity of the first generation of n. intermedia was greater than that of n. neivai, and its development time clearly shorter, particularly for the second and third larval instars.

Abstract: during a study of the phlebotomines of the brazilian state of tocantins, a new species was discovered in porto nacional county, here described as micropygomyia (silvamyia) echinatopharynx sp. nov. this is only the second species of the subgenus micropygomyia (silvamyia) to be described.
Description of Pintomyia (Pifanomyia) paleotrichia, a Miocene period new species from the Dominican Republic (Diptera: Psychodidae: Phlebotominae)
Andrade Filho, José Dilermando;Brazil, Reginaldo Pe?anha;Falco, Alda Lima;Galati, Eunice A Bianchi;
Memórias do Instituto Oswaldo Cruz , 2007, DOI: 10.1590/S0074-02762007005000110
Abstract: a new fossil species of phlebotomine sandflies is described from dominican amber based in one specimen. pintomyia (pifanomyia) paleotrichia sp. nov. is distinguished from the other extant and extinct species by aspects of paramere and the basal tuft of bristles in the gonocoxite.

Abstract: a sand fly fossil was found in amber, a vegetal resin, which allows all the external phlebotomine structures to be seen. the piece that contains the new species is 14 mm long ′ 8 mm wide ′ 3 mm high. all the structures from the head, thorax, and abdomen were examined under the microscope and measured with a calibrated micrometric eye-piece. the morphological aspects of the new species suggest its inclusion in the pintomyia genus, pifanomyia subgenus though it is not possible to include it in any of the series known for this subgenus. the presence of two atrophied spines on the gonostyles and gonocoxites without tufts of setae permit the exclusion of the new species from the other species of the subgenus pifanomyia. the new species is named pintomyia (pifanomyia) brazilorum sp. nov.

Memórias do Instituto Oswaldo Cruz , 2006, DOI: 10.1590/S0074-02762006001000010
Abstract: phlebotominae includes some vector species, mainly that of leishmaniases, with a very old host-parasite relationship. some species fossils of this subfamily have been recently described and this paper presents the description of a new sand fly pintomyia (pifanomyia) paleotownsendi sp. nov in amber. the gonostyle present four spines, being one apical, one external superior implanted close to the apical third, one external inferior in the middle of the structure and one internal implanted in the basal third. this disposition of the spines may separate the new species from others in the sub genus.
Description of Micropygomyia brandaoi sp. n. (Diptera: Psychodidae: Phlebotominae), a fossil phlebotomine from the Dominican Republic
Andrade Filho, José Dilermando;Galati, Eunice A Bianchi;Falco, Alda Lima;Brazil, Reginaldo Pe?anha;
Memórias do Instituto Oswaldo Cruz , 2008, DOI: 10.1590/S0074-02762008000400005
Abstract: the description of micropygomyia brandaoi, a new species of fossil phlebotomine sand fly, is based on one male specimen obtained from dominican amber of the miocene period (20 million years). in this new species, the fifth palpal segment is long, the coxite lacks a setal tuft and the style shows four well-developed spines. this set of characters allowed us to place the new species in the genus micropygomyia barretto.
Redescription of Nyssomyia intermedia (Lutz & Neiva, 1912) and Nyssomyia neivai (Pinto, 1926) (Diptera: Psychodidae)
Andrade Filho, José Dilermando;Galati, Eunice A Bianchi;Falco, Alda Lima;
Memórias do Instituto Oswaldo Cruz , 2003, DOI: 10.1590/S0074-02762003000800015
Abstract: the phlebotomine sand flies nyssomyia intermedia and nyssomyia neivai are the probable vectors of american tegumentary leishmaniasis in the southern and southeastern regions of brazil. these species form a complex, being difficult to separate between either females or males of the two members based on recognized morphological characteristics. both n. intermedia and n. neivai are redescribed here in the search for characters that facilitate their correct identification. it was possible to differentiate females by means of spermathecal characteristics. males could be separated with confidence by the tips of the genital filaments, which have the form of a deep spoon, the angle of the concavity being well accentuated in n. intermedia and much shallower in n. neivai.

Nyssomyia intermedia (Lutz & Neiva, 1912) and Nyssomyia neivai (Pinto, 1926) (Diptera: Psychodidae: Phlebotominae) geographical distribution and epidemiological importance

Memórias do Instituto Oswaldo Cruz , 2007, DOI: 10.1590/S0074-02762007005000035
Abstract: nyssomyia intermedia (lutz & neiva 1912) and n. neivai (pinto 1926) are possible vectors of tegumentary leishmaniasis in some regions of brazil. further, the latter was until recently, considered a junior synonym of the former. this study has the purpose of updating our knowledge of the geographical distribution of these species, based on specimens deposited at the collection of the centro de pesquisas rené rachou-fiocruz, faculdade de saúde pública-universidade de s?o paulo, and on data presented by literature as also to associate this distribution with the cutaneous leishmaniasis cases reported. it has been reported that n. intermedia occurs in the states of the northeastern region, in rio de janeiro, espírito santo, on the northern coast of s?o paulo, in eastern minas gerais, mato grosso do sul, and goiás, close to the border with minas gerais and bahia. n. neivai occurs in the southern region, southern coast and in western s?o paulo, southern and western minas gerais, southern goiás, and southern pará, beyond argentina, bolivia, and paraguay. it is important to highlight that n. intermedia and n. neivai occur in sympatry in minas gerais and s?o paulo. n. intermedia or n. neivai are predominant or are captured abundantly in several cutaneous leishmaniasis foci in the southeastern and southern regions of brazil.

Andrade Filho, José Dilermando;Galati, Eunice A. Bianchi;Falco, Alda Lima;
Revista Brasileira de Entomologia , 2006, DOI: 10.1590/S0085-56262006000300008
Abstract: nyssomyia intermedia (lutz & neiva) and nyssomyia neivai (pinto) are morphologically very close and both present great variation in some structures. the objective of this study is a description of the variation among the females of these species in populations from the states of minas gerais and s?o paulo. the morphological structures studied were the number of horizontal teeth in the cibarium and the number of rings and the shape of the terminal knob of the spermathecae. the spermatheca rings are significantly more numerous in n. intermedia than in n. neivai and the simple shape of the terminal knob predominated in both species. regarding the cibarium, eight to eleven teeth have been found in both species, with up to twelve teeth in the latter. the number of horizontal teeth and the shape of the terminal knob of the spermathecae were variable throughout the populations of both species and all structures were polymorphic in the populations studied.
