I have another Eriosyce to ID please, this one is from seed collected in habitat, collected and grown by John Henshaw (Croston Cactus). He's not sure what it is, thinking it might be paucicostata, but I think it might be a long spined form of heinrichiana.
EDIT: It does have a substantial taproot.
The collection point was a layby off the Panamericana Norte in the Coquimbo Region, Co-ords -29.3791981 -71.0909922

Here's photos of the parent plant and habitat:

Re: Another Eriosyce to ID
Id add eriosyce atroviridis to the possibilities. Also, those berries look tasty. edit But too big for the suggestion. Maybe Eriosyce taltalensis, esmeraldiana or napina seem to be a closer match fruit and spinewise. From what youve shown me in your on site photos, henirachiana has a different build in the wild(either taller, thiccker spines, or somewhat spineless-think theyre kinda unsure about ID).
Re: Another Eriosyce to ID
Pyrrhocactus heinrichiana is my best guess
Re: Another Eriosyce to ID
E. esmeralda and napina are Thelocephala's, a quite different section from the above plant.
E. paucicostata and E. neohankeana come from much further north in the Taltal/Paposo region, as does E. taltalensis sensu stricto. I have not had time to check what comes from around your quoted region yet.

Re: Another Eriosyce to ID
I've finally got around to checking Katterman's maps, which I should have done in the first place instead of being lazy!
The closest Horridocacti on his maps to the coordinates (-29.3791979, -71.0909919) are heinrichiana and kunzei/eriosyzoides, nothing else seems to be close by. It certainly doesn't seem to be kunzei/eriosyzoides!

Re: Another Eriosyce to ID
E. heinrichianus is fairly widespread in that area. In the past it used to be better known in cultivation as Pyrrhocactus jussieui, as Ritter called it at first and I think Knize did also, but Backeberg's name heinrichianus takes priority. If I remember correctly Knize's P. subikii is also part of the same population.
I have a job identifying a lot of these black spined Eriosyce (Horridocactus) since most look very similar in habitat and there is quite a range of variation in spination even in the same population. Also bodies can sometimes be greenish or blackish according to if they grow in shade or full sun. It's often "if its so and so locality it must be so and so species".
