Country

México

Types

Only a holotype has been assigned: UNAM 7705, 45.2mm SL, female.

Distribution

Type locality: Nacimiento de San Rafael de Los Castros, c. 15 km WNW of Ciudad Mante, Tamaulipas State, México (22o45’N, 99o05’W). This thermal resurgence cave is situated in the Sierra de El Abra (part of the Sierra Madre Oriental range). Epigean, eyed, Astyanax mexicanus, have been recorded from The Nacimiento de San Rafael de Los Castros (Mitchell, Russell and Elliott 1977).  P. lundbergi has now been discovered in Cueva del Nacimiento del Río Frío, Tamaulipas (Hendrickson, Krejca and Rodriguez Martinez 2001).

Habitat

The true habitat of this animal is not known. The holotype was collected from a depth of 4.5m at top of a deep, thermal (26.7oC), vauclusian rising. The substrate at this point was of silt and bedrock. In normal conditions this rising is not active but after rain it does resurge. It is possible that this outward flow will transport individuals from their true habitat which is deeper into the cave. Since two other hypogean ictalurids, Trogloglanis pattersoni and Satan eurystomus, are found in very deep artesian waters is in quite possible that P. lundbergi is also ‘speleo-bathyal’.

Systematics

Most closely related to its hypogean congener Prietella phreatophila which is, however, found over 600 km away. Detailed studies the four North and Central American troglobitic ictalurids Satan eurystomus, Trogloglanis pattersoni, Prietella phreatophila and P. lundbergi  by Arce et al. (2017) suggest that they form a monophyletic group with fifteen synapomorphies: 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. It would be highly valuable to compare these anatomical synapomorphies with those from molecular markers. 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

MuG [VU D2:3.1:2009]

VU D2:3.1:2009. (Snoeks, J., Laleye, P. & Contreras-MacBeath, T. 2009. Prietella lundbergi. The IUCN Red List of Threatened Species 2009:http://dx.doi.org/10.2305/IUCN.UK.2009-2.RLTS.T18137A7670013.en. Downloaded on 07 July 2017). Assessed as Vulnerable due to it inhabiting only two locations. P. lundbergi's very restricted distribution makes it extremely vulnerable to threats, such as water pollution, which would rapidly affect all the individuals in the population. However, it is mainly threatened by large-scale water extraction.

E (Contreras-Balderas, Almada-Villela, Lozano-Vilano and Garcia-Ramirez 2003). Since it may have a very limited range, and lives in a habitat that may be seriously affected by human disturbance (pollution, potential water abstraction etc), this species may be classed as endangered by the Mexican Government (H. E. Perez in Walsh and Gilbert 1995).
