Material examined earlier. Four localities in the State of Mexico, Mexico ( Kotov et al. 2003a).

Subspecies diagnosis. Chitinous insertions within distal segments of swimming setae far from bases of segments; on IDL 3 clusters of long setules; setules on distal lobe of limb II long; longest seta of exopodite III with long, fine setules; seta 1 of exopodite IV relatively short; a two-lobed body on inner margin of limb V.

Description, taxonomic comments. See Kotov et al. (2003a)

Distribution. At present, the subspecies is known with certainty only from the central Mexican plateau.
