Fritz , MACN, examined) Diagnosis. This species is similar to A. romeroi in size (length of forewing 5.9–7.3 mm ). It is distinguished by the color of the forewing, which has the entire apical margin darkened, and by the shorter pubescence. The hairs on the mesopleuron are 1.7–2.7x MOD (male) and 1.8–1.9x MOD (female). Males are characterized by the black scape and pedicel (8D). The shape of the hind basitarsus is similar to that of A. romeroi , with a basal inner rounded projection followed by a median tooth, but the apex is pointed (11D). The hidden sterna and genital capsule have been drawn by Rodríguez and Roig-Alsina (2004). Distribution . Argentina : province of Salta .
