The Bogardilla has not been observed in the wild since the late 1990s, despite repeated field surveys within its known range.

No ex situ populations exist, therefore this species is assessed as Extinct.

This species was endemic to the Jándula and Rumblar rivers, both of which are right-bank tributaries of the Guadalquivir River in southern Spain.

This species has not been observed in the wild since 1999, despite a series of field surveys covering its known range having been carried out.

This species was reportedly most abundant in flowing river and stream reaches with well-developed riparian vegetation and rocky to stony substrata, e.g., mixed bedrock, gravel and pebbles.

The upper parts of the Jándula River and most of the Rumblar River are characterised by seasonal variations in discharge, and can be significantly dewatered during summer. Some individuals would probably have survived these drought periods in remnant pools which function as refugia.

Little is known of its life history, but the annual reproductive period is understood to have taken place during April. It appears likely to have comprised an allopolyploid complex similar to the congeneric Calandino (Squalius alburnoides).

This species was probably extirpated through a combination of habitat loss due to the construction of dams and weirs throughout its range since the 1930s, plus the introduction of non-native aquatic species. The latter include Pumpkinseed (Lepomis gibbosus), Largemouth Bass (Micropterus salmoides), Common Carp (Cyprinus domestic strain), Common Bleak (Alburnus alburnus), Eastern Mosquitofish (Gambusia holbrooki) and Red Swamp Crayfish (Procambarus clarkii), all of which can negatively impact native species through predation, resource competition, habitat degradation or transmission of pathogens.

Habitat quality in some parts of the upper Jándula River may also have been negatively affected by pollution from intensive agricultural and mining activities in the area.

This species was not used or traded.

This species is listed (as Iberocypris palaciosi) in Annex II of the European Union Habitats Directive. It was assessed as Endangered in the Atlas and Red Book of the Freshwater Fishes of Spain (2002).

The majority of its range lies within protected areas included in the European Union's Natura 2000 network (sites ES0000090, ES6160006 and ES6160008), where it continues to be listed as a target species.
