| Elapsed time from first contact of the probe with the scorpion's body to the moment when the scorpion's aculeus touched the target was recorded as sting latency. |
| Characters of the females, primarily of the aculeus, and body and wing markings, were considered in identifying species of Anastrepha identified by Garcia and Zucchi. |
| At the end of the abdomen is the telson, which bears a bulb-shaped structure containing the venom glands and a sharp, curved aculeus to deliver the venom. |
| Aculeus typical for Tephrellini, elongate, with narrow needle-like distal part. |
| The specific name, aculeus, means 'spine' or 'thorn' in reference to the sharp spine-like projections on the apices of the uncal lobes. |
