( Figs 29–32 ) 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 . 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. Etymology. Named after Dra. Lívia Maria Fusari, in recognition for her friendship and continuous support. Male (n =1): Dimensions : Wing length/length of profemur 2.26. Coloration ( Figs 29A–E , 30A ): wings and abdomen follow figures 29A and 29E. Legs: P I , P II —femora with 1 band, tibiae without bands; P III —femora without bands, tibiae with 3 bands. Ratio of bands, related tibiae and tarsomeres 1 follow table 22. Hypopygium: gonocoxite brown and gonostylus yellow. TABLE 22.
