== Etymology ==
The name means "Echinopsis with bristles", referring to the floral tube covered with characteristic hairs and bristles.

== Description ==
'''Setiechinopsis''' is a monotypic genus of small, short-lived cacti with a distinctive floral morphology.

* '''Habit''': Small, usually solitary; sometimes branching; lifespan typically 3–5 years.
* '''Roots''': Short, thick taproot with fine secondary roots.
* '''Stems''': Cylindrical, strongly pigmented; brownish or purplish-green to nearly black.
* '''Ribs''': 11–12, low and straight.
* '''Areoles''': Covered with white wool.
* '''Spines''': 9–14 radial spines; 1 longer central spine; fine and slightly pubescent.
* '''Flowers''': Nocturnal, funnel-shaped, white, strongly scented; appearing near the apex; self-fertile.
* '''Floral tube''': Very long, slender, scaly, covered with hairs and bristles.
* '''Pollination''': By long-tongued moths (e.g. ''Manduca sexta'').
* '''Fruits''': Fusiform, drying at maturity; longitudinally dehiscent; floral remains persistent.
* '''Seeds''': Globose to elongated, dark brown, dull, tuberculate, with mucilage.

== Habitat ==
Occurs in unusual habitats for cacti:

* saline and brackish soils
* grasslands and open shrublands (e.g. ''Atriplex'')
* foothills and low mountain areas

Altitude range: approximately 200–1250 m.

== Distribution ==
Argentina:

* Catamarca
* La Rioja
* Mendoza
* San Juan
* San Luis
* Santiago del Estero

== Taxonomy ==
The genus has a complex history but is now widely accepted.

Key points:

* Originally described as ''Echinopsis mirabilis'' (Spegazzini, 1905)
* Later transferred to multiple genera (''Arthrocereus'', ''Acanthopetalus'')
* Often included in ''Echinopsis'' sensu lato in modern classifications
* Ritz et al. (2007): showed it is not part of ''Echinopsis''
* Las Peñas et al. (2010): cytogenetic evidence supports separation
* Albesiano & Kiesling (2012): identified multiple autapomorphies
* Schlumpberger & Renner (2012): placed it basally in a clade with ''Denmoza'' and related taxa

The genus is therefore recognized as distinct and evolutionarily isolated.

== Species ==
Monotypic genus:

* [[Setiechinopsis mirabilis]]

== Notes ==
* One of the shortest-lived genera within Cactaceae.
* Morphology shows strong convergence with ''Echinopsis'', but molecular data contradicts this relationship.
* Adapted to atypical, often saline environments.
* Represents an early-diverging lineage within its clade.
