Key to species of Dasymutilla   in Panama (Males)

This key should function for any Panamanian male mutillids that have the axillae armed with a posterior tooth or truncate projection, have T1 petiolate with T2, and have their tergal fringes lacking plumose setae. Although Traumatomutilla   are not treated here, the genus is included in the key to help with diagnosis.

1. S2 with a seta-filled pit.......................................................... 2 — S2 without a seta-filled pit....................................................... 6

2(1). Mesopleuron with a strong protuberance near tegula; S2 with a conspicuous longitudinal carina or keel running from anterior margin of sternal pit to anterior margin of segment; T2 mostly yellow..................................................... D. pulchra (Smith)  

— Mesopleuron without protuberance; S2 without longitudinal carina; T2 black or mostly yellow ............................................................................. 3
