Note

The status of the hypogean populations of Astyanax species in San Luis Potosi and Tamaulipas, Mexico, and the consequences for taxonomy and nomenclature, have been debated since their discovery in 1936. The problems have been exacerbated because there are no modern taxonomic or systematic studies of the genus. Although originally included in a separate genus (Anoptichthys) most references to these animals called them either Astyanax mexicanus (de Filippi 1853) or Astyanax  fasciatus (Cuvier 1819). This was in recognition that the hypogean and epigean populations are able to interbreed, a tenet of the Biological Species Concept. There are however many important autapomorphies in the hypogean populations and, under the Phylogenetic Species Concept, the hypogean and epigean animals are separate species. This debate will continue, but I have decided here to follow my own instincts and include the hypogean forms as a separate species. This decision is supported in the most recent authoritative account of the genus (Buckup 2003). In this account A. jordani is treated as a valid separate species, and is not placed in the synonymy of either A. fasciatus or A. mexicanus. Numerous other authors (e.g. Reddell 1981; Trajano 2001) accept that the hypogean and epigean fishes belong to different species. See also the discussion of this topic in Kullander (1999:339-340) which also concludes that the epigean and hypogean populations must be considered as separate species. Two of the most recent reviews of the biology of the fishes (Wilkens and Strecker 2017, Elliott 2018) also draw this conclusion.

There are complications ahead, as it is very likely that more than one invasion of caves from the surface has taken place and that more than one species is now present in the caves of the area. However, at least one of these (from the type locality, Cueva Chica) will be validly Astyanax jordani. The others will obtain names when the situation is better understood.

Synonyms

Anoptichthys jordani  Hubbs and Innes 1936

Anoptichthys antrobius  Alvarez 1946

Anoptichthys hubbsi  Alvarez 1947

These are the only true synonyms. Since the cave fish has often been regarded as conspecific with Astyanax mexicanus (de Filippi, 1853), and with Astyanax fasciatus (Cuvier 1819), it has often been referred to under these names. Reddell (1981:238 243, 325) provides a list of names used and a full bibliography to that date.

Habitat

Most of the populations are known from lakes and streams within the vadose region of the caves. Two exceptions to this are the populations in Sótano de Soyate and Sótano del Venadito which are almost certainly living in the low level phreatic zone of the karst area. In particular the Soyate population is in a huge deep lake-like area which is probably the main groundwater flow in this area. During high flow the water levels rise considerably and fishes from the phreatic populations may become washed into vadose areas and become stranded there for a time.

Systematics

This fish is the most extensively studied of cave dwelling animals. The reason for its pre-eminence is that it is easy to breed in captivity and interfertile with the epigean Astyanax mexicanus. These properties allow very detailed studies, and in particular genetical ones, to be made easily. A large number of publications have resulted from these studies (see Elliott (2018) and this web site for bibliographies) but there has been great confusion as to the name and status of the animal. The following discussion outlines the problem and poses a solution.

The first population to be discovered, in La Cueva Chica, was described by Hubbs and Innes (1936) as a new genus and species, Anoptichthys jordani. In the following ten years two other populations were discovered in La Cueva de El Pachon and La Cueva de Los Sabinos. Alvarez (1946, 1947) included them in the genus Anoptichthys as Anoptichthys antrobius and Anoptichthys hubbsi respectively. It is now known that the cave fishes are widespread (Mitchell, Russell, and Elliott 1977), (Reddell 1981:238‑243, 325), (Elliott 2018)  and there are now 31 known sites.

In their original description of Anoptichthys jordani Hubbs and Innes (1936) recognised that: "Anoptichthys agrees with the genus and subgenus Astyanax in all apparent characters other than those associated with blindness and subterranean life". The epigean Astyanax mexicanus (for a discussion of the Astyanax mexicanus / Astyanax fasciatus “problem” see Miller and Smith 1986) and the hypogean Anoptichthys jordani are not only very similar in morphology, but they possess the same (or very similar) karyotype (Kirby, Thompson, and Hubbs 1977) and are interfertile. These, plus the sympatric distribution, provide strong evidence that Anoptichthys jordani is very closely related to, and in all probability, directly evolved from, Astyanax mexicanus. There is therefore no reason for recognising a distinct genus for the cave fishes. (See Greenwood (1976), Roberts and Stewart (1976), and Banister and Bunni (1980) for discussions of this philosophy). So, should the cave and surface fishes be regarded as members of the same species (with specifically adapted local races) or as distinct subspecies or species within the genus Astyanax ? Most authors have uncritically accepted that they are conspecific because of the interfertility. However there are a number of trenchant differences between the epigean and hypogean populations. They differ in fright reaction (Pfeiffer 1977), feeding behaviour (Schemmel 1980), the distribution and density of the taste buds (Schemmel 1980), metabolic rate (Huppop 1986), the neuromasts of the lateral line (Teyke 1990) and in competitive abilities within the cave environment (Wilkens and Hüppop 1986). Although the epigean fishes can survive and breed in darkness (contrary to the evidence of Rasquin and Rosenbloom 1954) they are out-competed by the better adapted cave fish (Wilkens and Hüppop 1986). It is certain that the hypogean fishes could neither compete nor survive on the surface. The genetic distance (as calculated by Nei's D parameter) is also relevant to this discussion. Values for D of 0.142 (Pachon population) and 0.105 (Sabinos population) (Chakraborty and Nei 1974) fall within the ranges for both subspecies (0.004 ‑ 0.351) and species (0.004 ‑ 3.000) and above that for local races (0.000 ‑ 0.049) as given by Nei (1987). A simple reading of the biological species concept (Mayr 1970:12) would confine both surface and cave fishes to the same species as a result of their interfertility. Rosen (1979:275‑278; see also Kottelat (1997:10-20)) has argued however that the biological species concept is worthless as a determiner of relationships since its primary definer, reproductive compatibility, is a primitive (plesiomorphic) attribute of members of a lineage. It therefore has no power to specify relationships within a genealogical framework. In the present case it is obvious that the cave form exhibits a number of autapomorphies (see above). The two forms should therefore be considered as good separate sister species which have not yet attained reproductive isolation.

The taxonomic consequences of this would be: one species of cave‑dwelling fish Astyanax jordani (Hubbs and Innes 1936) with one junior objective synonym, Anoptichthys jordani Hubbs and Innes 1936, and two junior subjective synonyms, Anoptichthys antrobius Alvarez 1946 and Anoptichthys hubbsi Alvarez 1947.

The above discussion is based principally on morphology. Recent work by Richard Borowsky (e.g. Borowsky 1994, 1996; Borowsky and Espinasa 1997; Borowsky and Wilkens 2002; Espinasa and Borowsky 2000, 2001), indicates that there may have been at least three independent invasions of surface fishes all of which now exhibit similar troglomorphic facies. If this is the case, and we accept that genetic characters are useful, then there should have three different names (see Kottelat (1997) for an excellent discussion of these points). Recently Dowling, Martasian and Jeffery (2002), Strecker, Bernatchez and Wilkens (2003) and Wilkens and Strecker (2003) have also shown that some cave populations are independently derived from surface fishes.

Oliveira et al. (2011) made an extensive ingroup study of the Family Characidae. Their results strongly support a sister group relationship between Astyanax jordani and a group containing Astyanax aeneus, Bramocharax caballeroi and Bramocharax baileyi (Figure below), and explicitally not a sister group relationship with Astyanax mexicanus, which is sister to the four species listed above.

The above discussion was largely written for the first edition of my book (Proudlove 2006) and needs revising in the light of much information discovered in the 14 years since it was writen. However, it is worth empasising that the conclusion of the discussion, that the cave fishes should be called Astyanax jordani, is strongly supported in the two most recent reviews of the these fishes, their habitats and their history (Wilkens and Strecker 2017:70-74 and Elliott 2018:39-44) and in an extensive phylogentic study of the Family Characidae (Oliveira  et al. 2011) - see phylogenetic tree below.

Conservation Status

[NE]

R (IUCN, 1990), VU A1ac+2c,B1+2c,D2 (IUCN, 1996, 2000). These criteria indicate: (A1ac+2c) that the population has been, or will be, reduced by 20% over the past 10 years (and/or over the next 10 years) as a result of habitat loss or degeneration, (B1+2c) that the area of occupancy is less than 2000 km2 and a severely fragmented population with a decline in extent or quality of habitat, (D2) that the population exists in 5 or less sites. This latter criterion is not valid as the species is known from 31 sites (Mitchell, Russell and Elliott 1977, Elliott 2018). Special Concern (Contreras-Balderas, Almada-Villela, Lozano-Vilano and Garcia-Ramirez 2003).

Key References

This species has been studied in much greater detail than any other subterranean fish, and probably any other subterranean organism. Consequently the literature is very large. Anyone working with this species, or taking a serious interest in it, will need to follow the primary literature which is published across a very wide array of primary scientific journals. Those people starting out in research on Astyanax jordani, and those with a passing interest, will have to read and fully digest all of the major review publications, outlined below, all of which are required initial reading. Only by being fully familiar with these works can it be possible to move onto the primary literature with confidence that all the necessary background is firmly embedded in memory.
