Pereira, Luis Alberto, 2014, First report of geophilid centipedes of the genus Ribautia (Myriapoda: Chilopoda: Geophilomorpha) from the Atlantic Forest biome, with description of a new miniature species from Misiones Province, Northeastern Argentina, Zootaxa 3779 (4), pp. 433-455 : 434-435

Genus Ribautia Brölemann, 1909

Diagnosis. This genus can be distinguished from all other genera currently recognized in the family Geophilidae by the following combination of features. Second maxillae: united by a small coxosternal bridge only; antero-internal corners of coxosternite with a more or less developed process; prominent distally convergent ridges (statuminia sensu Crabill 1960) present. Forcipules: pleurocoxosternal sutures extending obliquely to the outer margin; chitinlines present; medial edge of trochanteroprefemur of telopodites either with a small unpigmented protuberance, with a conspicuous pigmented or unpigmented tooth, with two of these teeth, or without teeth. Sternal pores arranged in a single subcircular or longitudinaly elongate area on the anterior part of the trunk, in a single or two paired areas on the posterior part of the trunk (or even totally absent on the latter). Each coxopleuron of the ultimate leg-bearing segment with coxal organs, distributed in one of the following ways: (1) opening separately, (2) an anterior organ opening separately and all the remaining grouped in a cluster, (3) grouped in one to three clusters. Pretarsus of ultimate legs either claw-like or tubercle-like.
