TL;DR: Results of previous analyses based on palaeogeographic calibrations are not contradicted by the new approach, with vicariance by plate tectonics remaining as the main explanatory factor for the amphi-Atlantic distribution displayed by this ancient group of subterranean amphipods.

TL;DR: The western shore of the Indian Ocean was hitherto a vacant spot in the distribution of circumtropical shallow marine interstitial ingolfiellids and therefore the location of the new species fills a meaningful gap in the geography of the family.
Abstract: Ingolfiella arganoi sp. n. from Abd al Kuri Island in the Arabian Sea is described from two specimens, a male and a female. The western shore of the Indian Ocean was hitherto a vacant spot in the distribution of circumtropical shallow marine interstitial ingolfiellids and therefore the location of the new species fills a meaningful gap in the geography of the family. Morphologically, the new species shows close affinities with Ingolfiella xarifae from the Maldives.

TL;DR: The origin of these amphipods and their occurrence near or far from the present marine shore are considered as the result of a ‘Two-step Model of Colonization and Evolution’.
Abstract: The Metacrangonyctidae are distributed from the Canarian Archipelago to Israel and from the Balearic Islands to the pre-Saharian areas of Algeria, but Morocco seems to be the place where the family has especially split into a number of species now living in different parts of the Country. Data on the phylogenetic relationships of the family, on the geographic distribution of species in Morocco, and on the geological history of the regions inhabited by the different species lead us to consider the origin of these amphipods and their occurrence near or far (600 km) from the present marine shore as the result of a ‘Two-step Model of Colonization and Evolution’. The first step (vertical transition of the marine ancestors) may have occurred once during the Mesozoic period, some time before the Turonian period. The second step (horizontal transition of littoral interstitial ancestors) may have occurred once each time during the Turonian and the Senonian Cretaceous marine regressions for the different groups of Metacrangonyx species, and during the Lutetian Eocene regression for the species of the genus Longipodacrangonyx. The correlation between each lineage of Metacrangonyctidae and one marine regression seems to be corroborated by a similar pattern of distribution and evolution of the Moroccan Isopoda Cirolanidae. After acceptance of the above evolutionary scenario of Moroccan Metacrangonyctidae, the occurrence of one species of the family in a new area and its inclusion in one of the identified lineages may provide valuable information about some aspects of the historical geology of the area (i.e. the occurrence of Metacrangonyx repens in the Fuerteventura Canarian Island or those of M. longipes in Balearic Islands).

TL;DR: It is concluded that Metacrangonyx is a thalassoid lineage already present in the shores of the western Tethys before the complete aperture of the central North Atlantic (circa 110 Myr BP), and with marine populations persisting at both shores of this ocean until some time in the Quaternary, in case they have not yet disappeared.
Abstract: Members of the strictly stygobiont, continental subterranean amphipod family Metacrangonyctidae are reported for the first time outside the Old World. Two new species of Metacrangonyx are described from two widely separated localities in the Dominican Republic (Hispaniola), one facing the Caribbean and the other the Atlantic ocean. The discovery of metacrangonyctids in the western Atlantic suggests that they are an ancient subterranean lineage tied to the shores of the Tethys belt, and thus weakens previous biogeographic arguments raised to favour their separate and independent family status with respect to the Hadziidae. The discovery in the Mediterranean of marine populations of metacrangonyctids is reported as well, and both findings are used to test the reliability of the scenario currently held for the origin and evolution of this peculiar group of stygobiont amphipods. It is concluded that Metacrangonyx is a thalassoid lineage already present in the shores of the western Tethys before the complete aperture of the central North Atlantic (circa 110 Myr BP), and with marine populations persisting at both shores of this ocean until some time in the Quaternary, in case they have not yet disappeared. Evidence derived from Hispaniolan and Balearic Metacrangonyx does not support the correspondence between species-groups and the time at which precise waves of colonization of continental ground waters took place (after Turonian and Senonian marine regressions, respectively) as is assumed to occur for Old World taxa.
