Holotype: BMNH 1994.12.1:1 51mm SL. Paratype: BMNH 1994.12.1:2 48mm SL.
Known only from the type locality: River Cave 2 (=G14a), Canon Forestier, Ankarana, northern Madagascar (12o45’S,49o15’E).
Some fishes were seen in the flowing cave river while others were in pools above the dry season river level. In September the water temperature was 21oC. The food supply probably consists of a mixture of stygobitic and non-stygobitic Crustacea, and insects, detritus etc., brought in with the river and by lemurs, bats and birds (Wilson 1996).
Glossogobius giuris is a widespread species in the area and is similar in morphology (Banister 1994). Doha (1974) gives details of the biology of this species. Wilson (1996) records that Glossogobius callidus is found in Rive Cave 2.
Kuang et al. (2018) used molecular markers to study the internal structure of the Suborder Gobioidei which contains within it eleven Families. They demonstrated that Milyeringidae is sister Family to a group of four Families: Oxudercidae+Gobiidae+Butidae+ Eleotridae and is only disttantly related to four others: Odontobutidae, Rhyacichthyidae, Apogonidae and Kurtidae (samples from Thalasseleotridae and Trichonotidae were not availabe for analysis).
(Sparks, J.S. 2016. Glossogobius ankaranensis. The IUCN Red List of Threatened Species 2016: http://dx.doi.org/10.2305/IUCN.UK.2016-3.RLTS.T9267A58295968.en. Downloaded on 06 July 2017). CR B1+2c (IUCN 1996, 2000), VU D2:3.1:2004. The range of this cave-dwelling species falls entirely within the boundaries of Ankarana National Park. Its habitat is not subject to anthropogenic degradation and powerful "fady" (taboo) protects it from direct exploitation by the local populous. It currently has no exotic predators or competitors. The species is rarely collected given its isolated habitat, so further information is lacking. Surveys in recent years (2008, 2011) indicate that populations are relatively stable (J. Sparks pers. obs.). It is therefore assessed as Least Concern but the population should be monitored.
This species, and its undescribed congener Glossogobius sp., is found in Ecoregion 67 (Madagascar northwestern basins) of Thieme et al. (2005). This is an area of savana and dry forest rivers which is globally outstading faunistically with a conservation status of endangered and of Priority Class 1 (Sparks 2005).
