abdominal segments 2-6 ferruginous red ; wings very dark fuscous 
with a purple effulgence. Head, thorax basal and apical two 
abdominal segments covered with erect black hairs, the legs and 
sparse irregular apical fringes, dorsally and ventrally to the 2nd,

conical projections or teeth; forewings with two cubital cells and

intermediate and posterior tibiae without distinct spines. Abdomen

This form is unlike any Odontomutilla known to me, 
and has a coloration that is common in the males of many 
true Mutillas. 
Described from a single example.
