A trap-nesting program in northern Spain undertaken in cooper- 
ation with Dr. Enrique Asensio (Instituto Nacional de Investigaci- 
ones Agrarias, Valladolid) over the past few years has resulted in 
numerous nests of megachilids. One of these represents a new spe- 
cies of Protosmia Ducke. It is described here in order to make the 
name available for the description of its nesting biology, and is 
named in honor of Dr. Asensio, in recognition of his considerable 
help in this trap-nesting study. 
In the following description, abdominal segments are numbered 
based on the metasoma; expressions in parentheses in the descrip- 
tion of the male represent departures among male paratypes from 
characteristics described for the holotype.
