title: Description of Micropygomyia (Micropygomyia) ancashensis sp. nov. and the female of Lutzomyia (Helcocyrtomyia) chavinensis Pérez & Ogusuku (Diptera, Psychodidae, Phlebotominae) from Ancash department, Peru.
abstract: A male of a new species Micropygomyia (Micropygomyia) ancashensis sp. nov. and a female of the Lutzomyia (Helcocyrtomyia) chavinensis Pérez & Ogusuku, 1999 captured in the Antonio Raymondi province, department of Ancash, Peru are described and illustrated. The new species belongs to the cayennensis series, being closest to Mi. lewisi (Feliciangeli Ordoñez & Férnandez) though presenting highly sclerotized pseudotracheae on the labella that seem to constitute an autapomorphy among American Phlebotominae, and a clypeus almost completely covered with setae, as in Warileya. The female of Lu. chavinensis is close to those of Lu. blancasi Galati & Cáceres 1990, Lu. noguchii (Shannon, 1929), and Lu. pallidithorax Galati & Cáceres 1994.
