Review of the Spirobolida on Madagascar, with descriptions of twelve new genera, including three genera of ' fire millipedes' (Diplopoda) Wesener, Thomas Enghoff, Henrik Sierwald, Petra ZooKeys 2009 2009-09-04 19 19 1 128 7NL4S Brölemann, 1913 [514,695,1116,1142] Diplopoda Spirobolellidae Animalia Spirobolida 95 96 Arthropoda family  Of special potential phylogenetic interest are the small species of the South American genus  Atlanticobolus Hoffman, 1979, the West African genus  Amblybolus Keeton, 1964, as well as the here described Malagasy genus. In these three genera, the posterior gonopod coxites touch one another while a sclerotized sternite is absent. The gonopod pair is nevertheless connected by a membrane. At least the genus  Hylekobolus gen. n.with its conspicuously elongated posterior gonopods seems to fit well with the Spirobolellidae.
