Diagnoses. Nymphs: 1) frontal keel present; 2) lingua rounded apically; 3) glossa 0.8x length of paraglossa; 4) apex of paraglossa with rows of simple setae; 5) segment II of labial palp with a strong distomedial projection; 6) posterior margin of abdominal terga with pointed spines; 7) abdomen elongate.

Male imago: 1) turbinate eyes uniformly separated from each other, upper surface ellipsoidal; 2) terga with a light yellowish brown band along midline; 3) forceps with first segment distinctly constricted medioapically; 4) posterior margin of subgenital plate without a small rounded projection; 5) length of body relatively long (6.3 mm).

Distribution. PARAGUAY, URUGUAY, BRAZIL: Rio Grande do Sul, Paraná, Santa Catarina; Rio de Janeiro, Espírito Santo, Minas Gerais, São Paulo ( Fig. 1c View FIGURE 1 ).

Comments. Nymphs of A. longetron are present almost exclusively in banks with marginal vegetation in areas with slow to moderate current; they resemble A. alphus in several aspects, as mouthpart morphology and somewhat similar habitat ( Fig. 28 View FIGURES 27–30 ). However, the distribution of A. longetron is far restricted when compared to that of A. alphus . The altitudinal range of this species varies from 371 to 1063 m.a.s.l.
