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... |

Schendylops ramirezi sp. nov. (Myriapoda: Chilopoda), a tiny schendylid centipede (from Rio de Janeiro State, Brazil), is hereby described and illustrated based on the female holotype, male and female paratypes, and additional non-type specimens. This discovery represents the second geophilomorph species characterized by having twenty-seven leg-bearing segments, the lowest number recorded up to the present in the chilopod order Geophilomorpha. So far, this number of pairs of legs (27) had only been found in a single (male) specimen of Schendylops oligopus (Pereira, Minelli & Barbieri, 1995), collected in the vicinity of Manaus, Central Amazon (Brazil). New distribution records for S. oligopus (with which the new species is herein 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... |

Ityphilus betschi sp. nov. from French Guiana, (Chilopoda: Geophilomorpha: Ballophilidae) is here described and illustrated on the basis of the male holotype and a non-type female specimen. The new species is characterized by having the internal edge of the forcipular tarsungulum partially serrate; ventral pore-fields present along the entire body length; and all pore-fields undivided. It is compared in detail with the other Neotropical members of the genus sharing these three combined traits, and having a roughly similar range of leg-bearing segments, i.e., I. crabilli Pereira, Minelli & Barbieri, 1994 (from Brazil); I. demoraisi Pereira, Minelli & Barbieri, 1995 (from Brazil); I. guianensis Chamberlin, 1921 (from Guyana, Brazil,... |
