In 1997, 1998 and 1999 we performed several captures in the State of Piauí, in the counties of Barro Duro, Campo Maior, Castelo, Floriano, Picos, São Raimundo Nonato and Teresina. We used CDC light traps inside houses, in a primary forest and in one cave. Seventeen species were collected being
Lutzomyia longipalpis
,
Lutzomyia samueli
,
Lutzomyia whitmani
and
Lutzomyia lenti
the most captured species. The genus
Brumptomyia
,
L. whitmani,
Lutzomyia sordellii
,
Lutzomyia carmelinoi
,
Lutzomyia termitophila
,
Lutzomyia peresi
and
Lutzomyia quinquefer
are reported for first time in Piauí. We call the attention for the presence of
L. whitmani and
L. longipalpis, important vectors of leishmaniasis in various regions of South America.
