A new genus of Odontopygid Millipeds from Tanzania (Diplopoda: Spirostreptida: Odontopygidae)

The new generic taxon Calyptomastix is proposed to accommodate the type species Odontopyge kakandae Kraus, 1958, and, tentatively, Odontopyge dorsalis Carl, 1909, Haplothysanus leviceps Attems, 1909, and Spirostreptus pardalis Gerstäcker, 1873, all from Tanzania. This genus is defined by the broad basal separation of the male genitalia, the elongated basal whorl (torsion) of the gonopod telopodite, and the concealment of the solenomere within apical folds of the telopodite.Keywords: Odontopygidae, Calyptomastix, distribution, TanzaniaJournal of East African Natural History 101(1): 67–72 (2012
