Mecistocephalidae), with the description of a new species with unusually elongate denticles Naturalis
Bonato, L.; Minelli, A..
As a contribution to investigate the interspecific diversity in the large genus Mecistocephalus Newport, 1843 with respect to these centipedes’ predatorial role in soil tropical communities, we compared the patterns of maxillipede denticles in 32 species of the genus, and studied all published relevant information. All Mecistocephalus species share a conservative pattern of six distinct denticles on the mesal side of the four articles of each maxillipede. Current views on centipede phylogeny suggest that the basic pattern in Mecistocephalus originated from an ancestral array of fewer denticles, by addition of other denticles on the first and fourth articles of the maxillipede. These patterns are not affected by sexual dimorphism, and intraspecific...

The phylogenetic position of Dinogeophilus and a new evolutionary framework for the smallest epimorphic centipedes (Chilopoda: Epimorpha) Naturalis
Bonato, L.; Minelli, A.; Drago, L.; Pereira, L.A..
The centipedes of the clade Epimorpha change slightly during post-embryonic growth but there is huge variation between species in the maximum body size. New specimens of the rarely collected Neotropical genus Dinogeophilus provide further evidence that this genus comprises the smallest species of the Epimorpha, with a recorded maximum length of 5.5 mm. Up to now Dinogeophilus has been invariantly classified in Geophilidae but different sources of evidence (examination by SEM, cladistic evaluation of morphology, similarity and phylogenetic analysis of molecular data) agree on a very different phylogenetic hypothesis: Dinogeophilus is actually a derived lineage of Schendylidae, only distantly related to Geophilidae, and possibly belong to a mainly...
