USATypes
Only a holotype has been assigned: UMMZ 190922 (ex WMM 31.P.16.5) immature male 68.7mm SL. This species is the type species by original designation and monotypy of the cave‑restricted genus Satan.
Distribution
This species (and its confamilial Trogloglanis pattersoni) is restricted to very deep artesian waters (up to 600m) in the Central, or San Antonio, Pool of the Edwards Aquifer, Bexar County, Texas, USA (29o30’N, 98o30’W). It is distributed over an area of at least 500 km2 but has only been collected from man‑made wells which penetrate the aquifer. The collection localities are given below with depth in metres.
Artesian wells from which Satan eurystomus has been collected. Compiled from data in Longley and Karnei (1979). There may be more recent records from other sites.

Habitat
The underground cavities inhabited by this species and Trogloglanis pattersoni are probably the most extreme of any from which cave dwelling fishes are known. Details of the actual habitat are of course unknown and will probably remain so. What little is known has been gleaned from samples taken at the wells. Longley (1981) considered the aquifer to be the earths most diverse groundwater ecosystem and summarised its fauna. Kuehn and Koehn (1991) and Kuehn, O’Neil and Koehn (1992) isolated various fungi and algae which may play an important role in the trophic economy of the system. Northup and Lavoie (2001) suggest that bacteria growing at the interface between saline and freshwater may take part in the food web within this aquifer. Moraver and Huffman (1988) report the parasitic nematode Rhabdochona longleyi from both species of fishes. The most detailed account of the animals and their environs is that of Longley and Karnei (1979,1979).
Systematics
There are currently two principle hypotheses for the relationships of Satan eurystomus which are summarized in detail by Arce et al. (2017) and Lundberg et al. (2017). First is the relationship with the epigean and monotypic Pylodictis olivaris (Rafinesque 1818), first suggested by Taylor (1969) in his revision of Noturus. Lundberg et al. (2017) used HRXCT imaging to study the skelton of Satan and found 10 synapomorphies between the two species (see Dahdul et al. 2010 for details of the terminology) : 1. Head shape and mouth position, 2. Mesethmoid bone shape, 3. Lateral ethmoid posterior process, 4. Supraoccipital posterior process, 5. Parasagittal and occipital crests, 6. Opercular frame and panel, 7. First mandibular sensory canal pore, 8. Preoperculo-mandibular sensory canal foramina and pores, 9. Posterior ceratohyal, 10. Fourth supraneural and anterior nuchal plate. Some of these anatomical features are related to suction feeding in Pylodictis and Satan. There are a number of uncertainties in other anatomical features. The second hypothesis is that the four North and Central American troglobitic ictalurids Satan eurystomus, Trogloglanis pattersoni, Prietella phreatophila and P. lundbergi form a monophyletic group with fifteen synapomorphies (Arce et al. 2017): 1. Absence of eyes, 2. depigmentation, 3. Fifth vertebra, 4. Lateral line extent, 5. Mesethmoid cornua, 6. Anterior cranial fontanel, 7. Descending wing of frontal, 8. Supraoccipital posterior process, 9. Pterotic wings, 10. Parasphenoid and orbitosphenoid, 11. Abductor arcus palatine scars, 12. Anterior ceratohyal-ventral hypohyal joint, 13. Dorsal hypohyal, 14. Upper hypurals, 15. Transcapular ligament ossification. In addition to these synapomorphies Satan exhibits a number of singular features not seen in the other three ictalurid troglobites (Lundberg et al. 2017:155-157). It would be highly valuable to compare these anatomical synapomorphies with those from molecular markers but there are no suitable specimens of Satan from which to obtain tissue samples and no new living specimens have been seen for a decade or more. This group of four is the sister group to all other ictalurids in the analysis and they presumably share a last common ancestor which lived in the northern Mexico area.

Conservation Status
(NatureServe. 2014. Satan eurystomus. The IUCN Red List of Threatened Species 2014: http://dx.doi.org/10.2305/IUCN.UK.2014-3.RLTS.T19917A19032828.en. Downloaded on 07 July 2017). V (Miller, 1977), R (IUCN, 1988), V (IUCN, 1990), V (IUCN, 1993), VU D2 (IUCN, 1996, 2000). T1 (Williams, Johnson, Hendrickson, Contreras-Balderas, Williams., Navarro-Mendoza, McAllister and Deacon, 1989). G1 (NatureServe, 2002). This species is potentially threatened by overpumping of the aquifer, which is the primary source of water for people in the region. In the 1990s the world's largest water well (at that time) was drilled close to the known habitat of the species, and the water was briefly used to support a catfish farm; subsequently the well and water rights were purchased by the San Antonio Water System, which now uses the well for aquifer monitoring purposes. Depletion of the aquifer poses a threat by possibly allowing the poor-quality anaerobic water of the "bad water" zone to replace good-quality water where the fish now resides (G. Longley, The Handbook of Texas Online).
Pollution from industrial and agricultural sources is a potential threat, but protection of the aquifer for human uses will probably also protect the fish.
Longley and Karnei (1979b) point out, however, that the greatest threat to this animal is from depletion of the groundwater by pumping. Groundwater pollution could also pose a serious threat, especially in the light of the evidence gathered by Winograd and Robertson (1982) that the residence time of water in very deep aquifers may be as much as 10000 years. See also the San Marcos Recovery Plan (Edwards, Beaty, Longley, Riskind, Tupa and Whiteside 1984).
