In contrast to other subdivisions of its genus, which include many 
well known and abundant species, the strictly Neotropical Albomar- 
ginatus Group of Coccygomimus comprises insects for the most part 
elusive, which are found only occasionally even in those areas subject 
to regular collecting both by hand and by Malaise traps. For this 
reason, although the author recently published a monograph of the 
South American Coccygomimus (Porter, 1970), it was expected 
that new species of the Albomarginatus Group would appear as field- 
work became possible in previously unexplored regions. Indeed, 
shortly thereafter both sexes of an undescribed species were recovered 
from a Malaise trap situated in virgin subtropical wet forest near 
Aguas Blancas in northern Salta Province, practically on the Bolivian 
border. The present contribution describes this new species, dem- 
onstrating that it is related most closely to C. ramirezi from the 
yungas near La Paz, Bolivia.
