The original description of this species was based on a single female collected by T. Monod in a crater lake in

several important character states (rather small in dimensions, low number of acetabula and genital setae, well developed swimming setation comprising a group of anterior setae on IV-L-5), but differs in by far stouter leg segments. As these proportions could result from squeezing of the only available male specimen, the taxonomic weight of this difference remains unclear. I decide to accept the locality record with a question mark, but not to consider the specimen for the species diagnosis.
