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... |

Pectiniunguis gaigei (Chamberlin, 1921) from Guyana, (Chilopoda: Geophilomorpha: Schendylidae) is here redescribed and illustrated on the basis of type material. The species is characterized by the absence of pore-field on the first sternum; presence of undivided ventral pore-fields in an uninterrupted series along the whole trunk length; parunguis of walking legs thin and pale; and last leg praetarsus as a small tubercle with numerous spines. All these combined traits are shared by three other Neotropical members of the genus (P. geayi (Brölemann & Ribaut, 1911) from Brazil; P. ducalis Pereira, Minelli & Barbieri, 1995 from Brazil; and P. roigi Pereira, Foddai & Minelli, 2001 from Ecuador), with which P. gaigei is here compared in... |

The geophilomorph centipede Pectiniunguis minutus (Demange, 1968), a little known dwarf schendylid from Gabon (Western equatorial Africa), is redescribed and illustrated based on the type material and an additional non-type specimen preserved in the collections of the Muséum national d'Histoire naturelle, Paris. P. minutus can be easily differentiated from all the other species currently assigned to the genus Pectiniunguis, by the very low number of leg-bearing segments (35 in the males, 37 or 39 in the females) and very small body size (12-16 mm in length). P. minutus is also distinguished by having ventral pore-fields on the anterior region of the body only, this character being shared by a single species of the genus, i.e., P. ascendens Pereira, Minelli... |
