Ablabesmyia fusariae Neubern sp. n.

( Figs 29–32 View FIGURES 29 View FIGURES 30 View FIGURES 31 View FIGURES 32 )

Type material. Holotype: ♂ with larval and pupal exuviae, Brazil, São Paulo, São Carlos, Fazzari reservoir, 47°53`08``W – 21°58`07``S, xi.2004, L.M. Fusari — LEIA. GoogleMaps

Diagnostic characters. A. fusariae sp. n. differs from other species by combination of the following characters: Male —expanded megaseta, anal point present, aedeagal complex with with two types of blades aedeagal, smooth and grooved and with only 1 dorsal lobe; Pupa —morphology of anal lobe; Larva —head capsule expanded, ligula teeth in concave arch, dorsal pore present, projections postoccipital margin absent, procercus with 7 anal setae, posterior parapods with all claws yellow.
