Papéis Avulsos de Zoologia, 36(28): 323-331. and Guaporeptus paradisiusHoffman, 1988Hoffman, R.L. 1988a. Diplopoda from Rondonia, Brasil. I. Two new genera and species of Spirostreptidae. Papéis Avulsos de Zoologia, 36(28): 323-331., known only from the state of Rondônia, are made from the state of Mato Grosso, Brazil. Figures of gonopods, first and second leg-pair of males are provided. In addition, an updated list of 19 Spirostreptidae species from Mato Grosso is provided, with the species Plusioporus salvadorii, Trichogonostreptus (Oreastreptus) mattogrossensis, and Urostreptus tampiitauensis widely distributed in the state.
