“…intermedia by Dyar (1929) and Pinto (1930), a status which was maintained until their differentiation based on morphological and molecular approaches was proposed by Marcondes (1996). The morphological distinction was based mainly on the appearance of the spermathecae and the number of the horizontal teeth of the cibarium of the females, but it was not applicable to the male characteristics, despite the morphometric and artificial neural network analysis undertaken (Marcondes & Borges 2000). Nonetheless, due to the great polymorphism of the two species, the characteristics proposed by Marcondes (1996) for the distinction of their females could not always consistently be applied.…”

ABSTRACT. Nyssomyia intermedia (Lutz & Neiva) and Nyssomyia neivai (Pinto) (Diptera, Psychodidae, Phlebotominae) in a sympatric area: seasonal and nocturnal hourly rhythm in black and white modified Shannon traps. Captures with black and white Shannon traps were undertaken to identify aspects of the behavior of the two cryptic and sympatric species implicated as vectors of cutaneous leishmaniasis, Nyssomyia intermedia (Lutz & Neiva, 1912) and Nyssomyia neivai (Pinto, 1926). The traps were installed side by side, monthly, from July 2001 to June 2002, from 18 to 07 hours, in a peridomicile of Iporanga municipality, state of São Paulo, Brazil. A total of 2,142 specimens were captured, Ny. intermedia (47.4%) and Ny. neivai (50.5%). The white trap was more attractive to both sexes of both species. Males of Ny. neivai predominated (70%) over those of Ny. intermedia on the two traps; on the black trap, the females of Ny. intermedia predominated (63.3%) over those of Ny. neivai (36.7%). Seventy percent of the specimens of both species were captured between 18 and 24 h. Females of Ny. intermedia presented the highest peak at 19-20 h, and those of Ny. neivai at 20-21 h. The highest hourly average for females of Ny. intermedia on the black trap occurred in the winter and that for males in the summer. For Ny. neivai, both sexes predominated in the summer. The two species probably transmit the cutaneous leishmaniasis in the area due to their great predominance.

“…Measurement values for the wing venation (alpha length and alpha/beta ratio) of both sexes and the male ejaculatory pump/genital filament ratio were both significantly greater in N. neivai. Nevertheless, Marcondes and Borges (2000) were unable to distinguish between the males of these species with confidence based on their morphology and could only separate them using morphometric studies and analyse artificial neural network.…”

“…neivai (L. intermedia complex) was the prevalent species in all the sites sampled in the departments of Itapúa and Misiones. L. intermedia complex was recently differentiated in two species, L. intermedia sensu strictu and L. neivai (Marcondes 1996, Marcondes et al 1998, Marcondes & Borges 2000. The previous captures are referred here as L. intermedia s.l., although the specimens captured in Paraguay could be attributed to L. neivai considering the latitude and longitude where they were collected.…”
