Ablabesmyia parannulata Neubern   sp. n.

( Figs 57 View FIGURES 57 , 58 View FIGURES 58 )

Type material. Holotype: ♂, Brazil, Amazonas, Manaus, Catalão , 60°01`10``W – 03°08`00``S, 07.vii.2008, light trap, C.S.N. Oliveira & L.M. Fusari — LEIA GoogleMaps   . Paratypes: 2 ♂♂, same data as holotype— LEIA GoogleMaps   ; 2 ♂♂, Mato Grosso, Ribeirão Cascalheira, Suiamissu river, Campina Verde farm, 51°53`47``W – 12°55`59``S, 10.x.2007, light trap, L.C. Pinho — LEIA GoogleMaps   ; 6 ♂♂, same data as paratypes— DZUP GoogleMaps   .

Diagnostic characters. A. parannulata   sp. n. differs from other Ablabesmyia species   by the combination of the following characters: front and middle femora with 3 bands, hind femur with 1 band, middle tibia with 3 bands, m-cu positioned toward f-cu, R 3 apex close to C, gonostylus with 6 apical teeth; tapered megaseta, aedeagal blade extending beyond basidorsal lobe, dorsal lobe club-shaped with fringe and anal point present.

Etymology. Named due proximity to the species Ablabesmyia annulata ( Say, 1823)   .
