Venezuelan and Colombian members of the schismatotheline cluster, a group that sits oddly in the hobby's usual categories: New World, but with reduced urticating equipment and a temperament closer to the flighty dwarfs than the calm terrestrials.
Small to moderate, webbing, quick, and undemanding otherwise. The oddity is taxonomic as much as behavioural, and the group's placement has moved more than once.
Venezuelan export has been effectively closed for years, so circulating stock descends from older European lines on a narrow founder base. Listings are sparse, priced without anchors, and carried by a handful of breeders whose provenance is most of the identification. Obscurity, not difficulty, is the whole market structure.
