Ribautia is a genus of centipedes in the family Geophilidae. [1] [2] [3] This genus was described by French myriapodologist Henry Wilfred Brolemann in 1909. [4] [1] Centipedes in this genus are found in South America, tropical Africa, Madagascar, the Arabian peninsula, Australia, New Zealand, and Melanesia. [5]

Description

Centipedes in this genus feature elongate heads, elongate forcipules, and mandibles with long bristles. [5] The second maxillae are connected by only a narrow bridge in the middle of the coxosternite. [6] This coxosternite features processes projecting from the inner corners of the anterior margins and prominent sclerotized ridges. [6] [5] The forcipular sternite features a pair of narrow sclerotized stripes (chitin lines). [6] [7] Pores arranged in a single field appear on sternites on at least the anterior segments of the trunk. [6]

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. [5] The small species Ribautia platensis , [8] 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), [9] the minimum number recorded in this genus. [5] 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), [10] the African species R. paucipes (reaching 15 mm in length, with 39 leg pairs in type specimens including both sexes), [11] [12] and the Brazilian species R. onycophaena (reaching 13 mm in length, with 39 leg pairs in males and 41 in females). [13] 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), [14] the maximum number recorded in this genus. [5]

Phylogeny

A phylogenetic analysis of the order Geophilomorpha using both molecular data and morphology places a representative of the genus Ribautia in a clade with a sister group formed by representatives of two other genera in the family Geophilidae, Polygonarea and Hyphydrophilus . This phylogenetic tree suggests that these two genera are more closely related to Ribautia than any other genera included in this analysis. These three close relatives form a sister group for a representative of another genus in the same family, Plateurytion , which emerges as the next closest relative included in this analysis. These four close relatives also form a sister group for a representative of another genus in the same family, Steneurytion , which emerges as the next closest relative included in this analysis. [15]

This genus contains more than 50 valid species, including the following: [1] [2]
