The species G. hadesi is named after Hades, god of the underworld in Greek mythology and the husband of Persephone, the namesake of the first troglobite discovered among the soil centipedes.

The species G. hadesi has been observed in a cave as far as 1,100 meters below the surface, the deepest underground that any centipede has ever been recorded.

[3] This species was first described in 2015 by a team of biologists led by the Bulgarian myriapodologist Pavel Stoev of the National Museum of Natural History in Sofia, Bulgaria.

The original description of this species is based on three specimens collected by biospeleologists in 2011 from three different caves in the Velebit mountains in Croatia.

[3] Traits shared by these three species also include second maxillae that end in a stout tubercle with a small tip instead of a curved article that tapers gradually.

[3][9] Furthermore, the species G. persephones and G. hadesi also share troglomorphic features, such as long antennae and legs.
