In size like D. ruficeps, and otherwise similar, but of a lighter, brighter 

 rufous throughout; the back, rump, and ventral surface less olivaceous; 

 the pileum less trenchantly defined from the back. It resembles also

 pileum is rufous-chestnut, instead of olive-rufous, and is more con-

 from Yucatan and Campeche, Mexico, seem to be rather paler than 

 those from Guatemala, but the difference is barely appreciable,
