Diagnosis. FEMALE. This species is recognized by a unique combination of characters: the antennal scrobe is ecarinate; the gena is weakly carinae; the scutellar scale is distinct and is accompanied by anterior and anterolateral transverse carinae; the tibial spurs are white; the head and mesosoma are predominantly clothed with white to golden setae; and T2 has a pair of laterally situated whitish setal patches. MALE. This species can be recognized by a unique combination of characters: the clypeus is rounded anteriorly; the axillae are sessile basally and have a posteriorly directed tooth; the tibial spurs are white; the body is black except the mesosomal dorsum is usually reddish; T2 has a basal pair of laterally situated whitish setal patches; and the hypopygium is margined laterally by a sharp carina.

Distribution. Mexico, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica and Panama.

Remarks. This sex association and synonymy is based on coincidental distribution and a pair observed in copula in Isla Coibita, Veraguas. Dasymutilla spilota could be a junior synonym of Dasymutilla xalisco (Blake, 1871) (holotype female Mexico ANSP, No. 4507 examined). Females of both species are similar, except D. xalisco has the pubescent white patches of T2 connected medially, while in D. spilota they are separated medially. These pubescent patches, however, are variable in size in D. spilota , from widely separated medially to almost in contact. Also, the presence of male of D. spilota in Mexico ( Manley and Pitts 2007), suggests that both species might fall in synonymy.
