( Figs 14 View FIGURES 14 , 15 View FIGURES 15 )

Type material. Holotype: ♂, Brazil, Amazonas, Manaus, Cueiras park ZF02, 60°06`55``W – 02°35`22``S, 14.vii.2008, C.S.N. Oliveira — LEIA GoogleMaps   . Paratypes: 2 ♂♂, same data as holotype— LEIA GoogleMaps   ; 4 ♂♂, same data as holotype— DZUP GoogleMaps   .

Diagnostic characters. Ablabesmyia cordeiroi   sp. n. differs from other species by the combination of the following characters: femora with 2 bands, middle tibia with 3 bands, m-cu towards to f-cu, R 3 apex close to C, gonostylus with 6 apical teeth, tapered megaseta, grooved aedeagal blade, dorsal lobe club-shaped with fringe, anal point absent.

Etymology. Named after Dr. Danilo Pacheco Cordeiro, in recognition for his friendship and continuous support.
