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 . FIGURES 1–6. Anacroneuria magnirufa male., 1.

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. 6 ).
