This minute, vaguely colored species is closely related to /Spilochalcis 

 xantha, described below, in having the thorax broad, the anterior 

 margin of the pronotum acarinate, the head nearly one-half as long 

 as wide, and the vertex broadly rounded ; it differs in that the dorsum 

 of the thorax is very coarsely (rather than lightly) punctured, the 

 compound eyes and posterior ocelli are almost contiguous, the abdomen 

 is distinctly acuminate (rather than semiglobose), and the basal tooth 

 of the metafemur is acute rather than rounded. jS. pollens is also 

 slightly smaller and more vaguely marked than S. xantha.
