Ribautia is a genus of centipedes in the family Geophilidae. This genus was described by French myriapodologist Henry Wilfred Brolemann in 1909. [2] Centipedes in this genus are found in South America, tropical Africa, Madagascar, the Arabian peninsula, Australia, New Zealand, and Melanesia. [3]
Centipedes in this genus feature elongate heads, elongate forcipules, mandibles with long bristles, and sternal pores in one or two paired fields; the coxosternite of the second maxillae has sclerotized ridges and peculiar anterior projections. [3] These centipedes range from about 1 cm to about 7 cm in length and can have as few as 31 or as many as 125 pairs of legs. [3] The small species Ribautia platensis, [4] found in Argentina, measures only 9 mm in length and can have as few as 31 leg pairs (31 pairs in males, 31 or 33 in females), [5] the minimum number recorded in this genus. [3] Other small species of Ribautia with notably few legs include the Peruvian species R. williamsi (known from a female specimen measuring 12 mm in length with 37 leg pairs), [6] the African species R. paucipes (reaching 15 mm in length, with 39 leg pairs in type specimens including both sexes), [7] [8] and the Brazilian species R. onycophaena (reaching 13 mm in length, with 39 leg pairs in males and 41 in females). [9] The large species R. taeniata , found in New Caledonia, can reach 75 mm in length and can have as many as 125 leg pairs (105 to 121 pairs in males, 111 to 125 in females), [10] the maximum number recorded in this genus. [3]
There are over 50 valid species, [2] including:
Pachymerium syriacum is a species of centipede in the family Geophilidae. The original description of this species is based on a female specimen measuring 110 mm in length with 87 pairs of legs. Authorities now place this species in another genus under the name Gnathoribautia syriaca, a species found in Turkey, Greece, and Lebanon.
Geophilus is a large, heterogeneous genus of soil centipedes in the family Geophilidae largely considered to be synonymous with Brachygeophilus. This genus is mostly Holarctic and characterized by a claw-shaped ultimate pretarsus, complete or nearly complete coxo-pleural sutures at the prosternum, and incomplete chitin-lines. Centipedes in this genus feature slightly elongate heads and labral intermediate parts with tubercles, the forcipules are usually poorly elongate with a single small tubercle at the base of each tarsungulum, and the anterior trunk metasternites usually have an anterior medial socket and a posterior transversally elongate pore-field. The generic name first appeared in Brewster's Edinburgh Encyclopaedia in 1814 as Geophilus electricus.
Schendylidae is a family of centipedes in the order Geophilomorpha found in the Americas, the Palearctic region, Africa, Madagascar, Australia, and southeast Asia, and also on some Pacific islands.
Sepedonophilus is a genus of three species of centipedes in the family Geophilidae. This genus is endemic to Australia, and was first described by Austrian myriapodologist Carl Attems in 1909. Centipedes in this genus feature scattered coxal pores and have no sternal pores; the lateral parts of the labrum almost touch medially, and the intermediate part is inconspicuous; the coxosternite of the second maxillae have peculiar anterior projections. These centipedes range from about 2 cm to 5 cm in length and have 49 to 79 pairs of legs. The smallest species in this genus, Sepedonophilus hodites, measures only 18 mm in length and has only 49 leg pairs, the minimum number recorded in this genus, whereas the largest species, S. perforatus, measures 50 mm in length and has 79 leg pairs, the maximum number recorded in this genus.
Pachymerinus is a genus of centipedes in the family Geophilidae. It was described by Italian entomologist Filippo Silvestri in 1905. Centipedes in this genus feature elongate heads, elongate forcipules with denticles, scattered coxal pores, and few sternal pores, if any; the intermediate part of the labrum is narrow and has no denticles. These centipedes range from about 3 cm to 8 cm in length, have 47 to 81 pairs of legs, and are found in Chile and southeast Australia. The Australian species Pachymerinus froggatti is notable for its relatively small size, measuring only 28 mm in length. The larger Chilean species P. porteri measures 46 mm in length but can have as few as 47 leg pairs, the minimum number recorded in this genus. The Chilean species P. pluripes measures only 32 mm in length but can have 79 or 81 leg pairs, the maximum number recorded in this genus. The Chilean species P. canaliculatus is known from a female specimen with 75 leg pairs and is notable for its large size, measuring 75 mm in length.
Queenslandophilus is a genus of centipedes in the family Geophilidae. It was described by German myriapodologist Karl Wilhelm Verhoeff in 1925. Centipedes in this genus feature second maxillae with sclerotized ridges on the coxosternite, no sternal pores, and coxopleura many scattered pores; the lateral parts of the labrum almost touch medially, and the ultimate legs most often have claws. These centipedes range from 1 cm to 6 cm in length, have 37 to 75 pairs of legs, and are found in Australia, Japan, and North America. The Japanese species Queenslandophilus monoporus and Q. macropalpus are notable for their small sizes, measuring only 10 mm and 15 mm in length, respectively. The species Q. elongatus, found in California, is notable for its large size, ranging from 40 mm to 63 mm in length. The species Q. macropalpus has only 37 leg pairs, the minimum number recorded in this genus, whereas Q. elongatus has 73 to 75 leg pairs, the maximum number recorded in this genus.
Ribautia aggregata is a species of centipede in the Geophilidae family. It is endemic to Australia, and was first described in 1915 by French myriapodologist Henry Wilfred Brolemann. Females of this species have 67 to 71 pairs of legs and are about 50 mm long.
Ribautia rainbowi is a species of centipede in the Geophilidae family. It is endemic to Australia, and was first described in 1912 by French myriapodologist Henry Wilfred Brolemann.

Centipedes in this genus feature second maxillae with claws fringed by two rows of filaments, transversally elliptical sternal pore-fields on almost all trunk segments, two pores on each coxopleuron, and ultimate legs without claws. These centipedes range from 16 mm to 67 mm in length, have 35 to 73 pairs of legs, and are found in the tropical and subtropical regions of the Americas, Fiji, and west Africa. The African species Pectiniunguis minutus is notable not only for being the smallest in this genus but also for having as few as 35 leg pairs, the minimum number in this genus. The Brazilian species P. ducalis is notable not only for being the largest in this genus but also for having as many as 73 leg pairs, the maximum number in this genus.
