First Time

The phlebotomine sand fly Pintomyia monticola (Costa Lima, 1932) is recorded for the first time in Brasília, central-west Brazil. A review of the geographical distribution of the species in South America is presented, and its distribution is extended. The potential geographical distribution of P. monticola is predicted based on ecological niche modeling. Ecological aspects of this species are discussed.

The genus Psammolestes is comprised of three recognized Rhodniini species: P. arthuri, P. coreodes, and P. tertius. The geographical distribution of these triatomines in South America was analyzed using ecological niche modeling. Additionally, temperature, precipitation, and altitude limits for these species were estimated. The genetic algorithm for rule-set production (GARP) was applied to predict their geographical distribution. The models used were able to predict, with high probabilities, the occurrence of P. tertius in open woodlands of South America (mainly Cerrado and Caatinga ecoregions), making it the Psammolestes species with the widest distribution. P. arthuri presented a discontinuous potential distribution covering the Venezuelan Llanos and southeastern/southwestern fringes of Amazonia. P. coreodes presented the southernmost area of distribution, occurring mainly in the Argentinean Chaco. The models also support potential areas of co-occurrence for P. tertius and P. coreodes in southwestern Brazil. Clear ecological niche differences were observed for the three species: while P. arthuri occurred in warm and humid areas, P. coreodes occupied the driest and coldest areas. P. tertius presented intermediate climatological limits and occurred in the highest altitudes. Although climatic factors may determine the triatomine distribution, biotic factors, such as the association with thornbirds (Phacellodomus), may also influence the geographical distribution of Psammolestes species. Finally, this study confirms the usefulness of ecological niche modeling as a tool for studies on biogeographical aspects of triatomines.

Ecological niche modeling of Triatominae bugs allow us to establish the local risk of transmission of the parasiteTrypanosoma cruzi,which causes Chagas disease.This information could help to guide health authority recommendations on infection monitoring, prevention, and control. In this study, we estimated the geographic distribution of triatomine species in Colombia and identified the relationship between landscape structure and climatic factors influencing their occurrence. A total of 2451 records of 4 triatomine species (Panstrongylus geniculatus,Rhodnius pallescens,R. prolixus, andTriatoma maculata) were analyzed.The variables that provided more information to explain the ecologic niche of these vectors were related to precipitation, altitude, and temperature. We found that the species with the broadest potential geographic distribution wereP. geniculatus,R. pallescens, andR. prolixus. In general, the models predicted the highest occurrence probability of these vectors in the eastern slope of the Eastern Cordillera, the southern region of the Magdalena valley, and the Sierra Nevada of Santa Marta.
