Key to species of Dasymutilla in Panama (Females)

This key should function for any Panamanian female mutillids that have a pygidium at least partially defined by lateral carinae on T6, have T1 petiolate or sub-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. Tibial spurs white, contrasting with brown to black tibiae............................. 2 — Tibial spurs black, concolorous with black legs....................................... 4

2(1). T2 marked with two white setal patches, integument brown to black beneath patches ( Fig. 14 )............................................... D. spilota Manley and Pitts

— T2 marked with two or four whitish to yellow integumental patches..................... 3

3(2). Mesosoma red, contrasting with black head, T2 with two small white pale integumental patches on discal area ( Fig. 17 ); pygidium higher than wide, narrow at base ( Fig. 19 )........................ D. colorado Cambra, Williams and Quintero , sp. nov.

— Head and mesosoma black, T2 with two or four yellow integumental patches; pygidium generally broad, nearly as wide as high............................ Traumatomutilla André

4(3). Scutellar scale absent, mesosoma elongate with dorsal propodeal face longer than posterior face ( Fig. 6, 9 ); subgenal carina present, parallel with genal carina....................... 5

— Scutellar scale present, mesosoma perpendicularly truncate posteriorly, posterior propodeal face as long or longer than dorsal face ( Fig. 3, 12 ); subgenal carina absent................. 6

5(4). Pygidium convex, with lateral carinae obscure posteriorly; clypeus evenly convex; T2 apical fringe and T3 predominantly with black setae......................... D. phya (Cameron)

— Pygidium flat, defined by a distinct carina on the apical and lateral margins; clypeus with longitudinal medial tubercle; T2 and T3 predominantly with golden setae or interspersed black and golden setae................................. D. paradoxa (Gestaecker)

6(4). T2 black but marked with four golden yellow integumental patches that can be medially confluent; mesonotal dorsum armed with lateral tubercle ( Fig. 11 )............ D. pulchra (Smith)

— T2 marked with two white setal patches, integument black beneath patches; mesonotal dorsum rounded laterally ( Fig. 2 ).................................. D. araneoides (Smith)
