With Chalon Boesel. We were on a search for a unknown snail in Campo reported by Miller years ago. I thought this was possibly an immature H. edwardsi, but when I got home and looked under the scope, it proved to be mature and had the incised lines of a traskii group snail. Perhaps this is H. traskii isidroensis? Or Miller's mystery snail? It doesn't look like a typical traskii.
Chalon will post more photos, and I will as well. This looks very much like https://www.inaturalist.org/observations/10407945, found near Portrero a few years ago, which generated much discussion.

In range for Helminthoglypta micrometalleoides. We had misinterpreted the type locality of this species in Miller 1970, and hence ended up at this habitat. Pretty shocked to find snails of any form here, period.
