Diagnosis. Using the key in Stark (1998), the presence of a yellow median pronotal band, the lack of a hammer, and a wing length of 20–22 mm, the male readily runs to “ A. magnirufa  ”. However, the aedeagus of the true A. magnirufa  lacks the narrower apex and the thin transverse ridge. Additionally, the dorsal head patterns differ. The complete lack of a hammer of this species is shared by two other Central American species, A. brava Mayorga and Contreras-Ramos, 2017  from Mexico ( Mayorga and Contreras-Ramos 2017), and the A. tuberculata  sp. n. from Costa Rica. The dark coloration and the distinctive aedeagus of A. brava  easily distinguish this species from both A. magnirufa  and A. tuberculata  .

Comments. Jewett (1958) described A. magnirufa  based on a female adult holotype from Chiriquí Province, El Volcán, Panama. The male ‘allotype’ and a male paratype were from Honduras. Stark (1998) treated A. magnirufa  based on specimens from Costa Rica, noting however, that the Panamanian males “are larger and have a slightly wider aedeagal apex and less conspicuous dorsal keel than Costa Rican specimens.” Additionally, the subgenital plate of the species being provided a new name below has a mesal tubercule near the subgenital plate notch ( Stark 1998, fig. 144). The subgenital plate of all Panamanian females of A. magnirufa  examined in this study lacked this tubercle ( Fig. 6View FIGURES 1–6).
