HOLOTYPE.—USNM 73710.

TYPE-LOCALITY.—Santiago, Rio Colorado.

Described from the unique male holotype (10 Apr 1953, L. E. Peña).

Although atypical by reason of its divided uncus, D. glebula nevertheless keys to this group. A different generic designation is indicated here but in the absence of more material I leave D. glebula in this genus.

Superficially, D. glebula resembles closely darker examples of the North American Agonopterix argillacea (Walsingham), but is immediately distinguishable structurally.
