Bousquet and Grebennikov (1999) redescribed the species and illustrated the male and female genitalia.

Taxonomic Note.

With the exception of accessory setae on the pronotum, elytra, and mesosternum, this species is structurally very similar to those of Patrobus and possibly simply represents an offspring of Patrobus . The larva does not differ significantly from those of Patrobus (Bousquet and Grebennikov 1999).
