A new dwarf species, new distribution records, and supplementary descriptive notes of the centipede genus Ityphilus Cook, 1899 (Chilopoda: Geophilomorpha: Ballophilidae) from central Amazonia, Brazil
Provedor de dados: 84
Autores: Pereira,Luis Alberto.
A new dwarf species of the centipede genus Ityphilus Cook, 1899, named I. donatellae sp. nov. (Chilopoda: Geophilomorpha: Ballophilidae) is hereby proposed on the basis of specimens from the vicinity of Manaus, Central Amazonia (Brazil), previously identified as Ityphilus calinus Chamberlin, 1957 (hereby designated holotype female, paratype male and paratype female). Supplementary morphological data and new illustrations are provided after this type material. The new species, characterized by having the internal edge of the forcipular tarsungulum serrate, is herein included in a key that will enable the identification of the 10 other Neotropical members of the genus Ityphilus sharing the same trait. New distribution records and supplementary descriptive...

Redescription of Pectiniunguis gaigei (Chamberlin, 1921) from Guyana, with new distributional data and complementary descriptive notes on similar neotropical species (Chilopoda: Geophilomorpha: Schendylidae)
Provedor de dados: 84
Autores: Pereira,Luis Alberto.
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 &amp;amp; Ribaut, 1911) from Brazil; P. ducalis Pereira, Minelli &amp;amp; Barbieri, 1995 from Brazil; and P. roigi Pereira, Foddai &amp;amp; Minelli, 2001 from Ecuador), with which P. gaigei is here compared in...

Discovery of a second geophilomorph species (Myriapoda: Chilopoda) having twenty-seven leg-bearing segments, the lowest number recorded up to the present in the centipede order Geophilomorpha
Provedor de dados: 84
Autores: Pereira,Luis Alberto.
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 &amp;amp; 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...

A further contribution to the knowledge of Pectiniunguis minutus (Demange, 1968), a little known dwarf schendylid centipede from western equatorial Africa (Chilopoda: geophilomorpha)
Provedor de dados: 84
Autores: Pereira,Luis Alberto.
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...

First record of a ballophilid centipede from French Guiana with a description of Ityphilus betschi sp. nov. (Myriapoda: Chilopoda: Geophilomorpha)
Provedor de dados: 84
Autores: Pereira,Luis Alberto.
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 &amp;amp; Barbieri, 1994 (from Brazil); I. demoraisi Pereira, Minelli &amp;amp; Barbieri, 1995 (from Brazil); I. guianensis Chamberlin, 1921 (from Guyana, Brazil,...
