), though in the numerous examinations made, none appeared to have sperm in the spermatheca. Presence of a well-developed female reproductive tract does not, by itself, disprove that the species is parthenogenetic (it may simply be a retained attribute), but there appears to be good circumstantial evidence that this species has only females.

, which also shares a similar ecology: small forested streams and stream pools. While it may seem tempting to claim this is an artifact of collection bias, the region has been subjected to intensive collection efforts for aquatic beetles in the last decade. We have examined more than 100,000 water beetle specimens from northern South America. While we presume the distribution of the genus is certainly more widespread than is currently known, this general biogeographic pattern seems likely to hold and warrants further study.
