Note

Historical notes

The first specimens were collected in July 1956 by Renaud Paulian, Director of the Institut de Recherche Scientifique de Madagascar, in caves near the Baie des Assasins, between the towns of Morombe and Toliara (formerly Tulear), southwest Madagascar. The species was described three years later by Jaques Arnoult of the zoological laboratory of the Museum National d'Histoire Naturelle de Paris. The name is derived from the collector. (Information from Berti and Messana 2010).

Synonyms

None.

At Tehafe one specimen may have been a hybrid between T. madagascarienisis and T. pauliani.

At Tehafe one specimen may have been a hybrid between T. mararybe and T. pauliani.

Habitat

Very little information is available. This species and its congeners, T. madagascariensis and T. mararybe appear to live in vadose caves.

Systematics

Vences, Rasoloariniaina and Reimann (2018) obtained tissue samples from 122 individuals of the three Typhleotris species (T. madagascariensis, T. pauliani and T. mararybe). These were analysed to get DNA sequences fron one mitochondrial gene (cox1) and two nuclear genes (kiaa1239 and rag-1). cox 1 sequences were obtained from 118 individuals from 11 localities, rag-1 from 19 individuals from 6 localities and kiaa1239 from 85 individuals from 12 localities. The cox1 marker showed a clear separation of the thee nominal taxa but with some suggestion of hybridization between T. pauliani and T. madagascariensis and between T. pauliani and T. mararybe. All individuals of T. mararybe belong to one clade but both of the other species are divided into two clearly separate clades. Three geographic groupings were revealed. The northern group consisted only of one clade of T. pauliani at Safora, conderably separate from the central and southern groups. All T. maraybe sampled were in the southern group together with one clade of T. madagascariensis and the central group consisted only of the second clade of T. magagascariensis. The second clade of T. pauliani is found in both central and southern groups.

Chakrabarty, Davis and Sparks (2012) demonstrated that the three Madagascar species of Typhleotris are the sister group to the two Australian species of Milyeringa. They placed all five known species in the family Milyeringidae Whitley 1945. This action was fully supported by a multiple molecular marker study by Page et al. (2018).

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).

Conservation Status

TLO, MuG [CR B1ab(iii):3.1:2016]

(FishBase team RMCA & Sparks, J.S. 2016. Typhleotris pauliani. The IUCN Red List of Threatened Species 2016: http://dx.doi.org/10.2305/IUCN.UK.2016-3.RLTS.T22596A58303542.en. Downloaded on 06 July 2017). VU D2 (IUCN, 1996, 2000), “fragile et vulnerable” (Kiener 1972). This species is endemic to southwestern coastal Madagascar and occurs in the vicinity of Andalambezo. It has a restricted range and a patchy distribution, given it only occurs in subterranean habitats and interconnected sites such as caves, sinkholes and wells. For this species, the estimated extent of occurrence (EOO) is approximately 100 km². It is in a single location threatened by increasing tourist visitation and collection of guano. On this basis this species is assessed as Critically Endangered.

This species is found in Ecoregion 87 (Madagascar southern basins) and Ecoregion 68 (Madagascar western basins) of Thieme et al. (2005). These are respectively xeric and savanna-dry forest regions. Er87 is regionally outstanding with a conservation status of relatively stable and a priority class of 5 (Sarks 2005). Er68 is continentally outstanding, with a conservation status of vulnerable and a priority class of 2 (Sparks 2005)
