Abstract. American Tegumentary Leishmaniasis is an endemic disease in north of Argentina. Different epidemic and focused outbreak scenarios were registered in Salta. This antecedent shown the need of carrying out more detailed and recent in situ studies of vector. Objectives were, identify species of Lutzomyia and determine which of them was the most prevalent one. The collects were made in the Farm “El Oculto” Orán, Salta, belonging to the Yungas; collects were seasonal and during a year. These were made in non-modified environments, border zones and peridomestic sites. CDC miniature light traps were used, during four hours in the noon and Shannon trap with human protected bait during three hours from the twilight. In this study 1064 sand flies were identified, 93,9 %  Lu. neivai, 5,8 %  Lu. shannoni  and  0,3 % Lu. cortelezzii. Lu. neivai was the most abundant species among all the environments and the only one in the peridomestic sites; in these places we can observe  antropic changes. Lu. neivai shows a great adaptability to environments that suffered these changes. Although they were not registered leishmaniasis cases in the studied locality, this one is quite close to places of risk.
