Table 1. Human perception tests of mimetic fidelity of Psorthaspis species reported by volunteers (N = 35).
| Spider wasp species | Average mimetic fidelity score | SD | Assigned mimicry ring |
| P. formosa | 4.60 | 2.19 | Madrean |
| P. texana | 4.71 | 3.18 | Texan |
| P. connexa | 8.74 | 1.52 | Tropical |
| P. variegata | 6.29 | 2.53 | Tropical |
| P. legata | 8.83 | 1.69 | Eastern |
| P. mariae | 6.74 | 2.17 | Eastern |
| P. sanguinea | 6.63 | 2.17 | Eastern |
| P. portiae | 5.26 | 2.13 | Western |
| P. nigriceps | 5.89 | 1.91 | Western |
Average mimetic fidelity of each spider wasp species indicates how well each species matches the velvet ant mimicry ring it was phenotypically and geographically most similar to. Scores are based on a scale of 1 (very poor mimic) to 10 (excellent mimic).
