A new species ofItyphilus(Chilopoda: Geophilomorpha: Ballophilidae) from the tropical rainforest of French Guiana, northern South America

Abstract

Ityphilus geoffroyi sp. nov. (Chilopoda: Geophilomorpha: Ballophilidae) is herein described and illustrated from the holotype female, paratype male and additional non type specimens collected in French Guiana. The new species is characterized by having the internal edge of the forcipular tarsungulum partially serrate; antennae apically distinctly thickened; ventral pore-fields present in an uninterrupted series along the entire body length; all pore-fields undivided; and sternite of leg-bearing segment 1 bearing a pore-field. It is compared in detail with I. demoraisi Pereira, Minelli & Barbieri, 1995 (from Brazil) and I. guianensis Chamberlin, 1921 (from Guyana) which share these five combined traits and have a roughly similar range of leg-bearing segments. Ityphilus geoffroyi sp. nov. is only the fourth geophilomorph centipede recorded from this vast French overseas Department in northern South America, the others being I. betschi Pereira, 2010 (Ballophilidae), Schendylops tropicus (Brölemann & Ribaut, 1911) (Schendylidae), and Ribautia proxima Pereira, Minelli & Barbieri, 1995 (Geophilidae).

First record of the endemic Neotropical genusHyphydrophilus(Chilopoda: Geophilomorpha, Geophilidae) from Argentina, with description ofH. minelliisp. nov., a new centipede with small tentorial process, inhabiting the Yungas

“…A detailed account of the epimorphic centipedes, for which the maximum body length measured in adults is 11 mm or less, can be found in Bonato et al (2015). Several other species with reduced body size are known to occur for diverse families of the Geophilomorpha (see Crabill 1960;Pereira et al 1994Pereira et al , 1995Pereira et al , 2000Foddai & Minelli 1999;Minelli et al 2000;Foddai et al 2003;Minelli 2003;Uliana et al 2007;Pereira 2009Pereira , 2011Pereira , 2012Pereira , 2013aPereira , 2013bPereira , 2013cPereira , 2014aPereira , 2014bMoretto et al 2015).…”

A new species ofRibautiaBrölemann, 1909 (Chilopoda: Geophilomorpha: Geophilidae) from Peruvian Amazonia, with a key to the Neotropical species of the genus with coxal organs grouped in clusters

“…nov. (with 12 mm body length), a few other Neotropical species of Ribautia have a similar small body size (see Pereira 2014). Several other occurrences of species with reduced body size are known for the Geophilomorpha; besides the Geophilidae, this is known to occur in some genera of the Aphilodontidae, Ballophilidae, Linotaeniidae, Macronicophilidae, Mecistocephalidae, and Schendylidae (see Foddai & Minelli 1999;Minelli et al 2000;Pereira et al 2000;Foddai et al 2003;Minelli 2003;Uliana et al 2007;Pereira 2009Pereira , 2011Pereira , 2012Pereira , 2013aPereira , 2013cPereira , 2013dPereira , 2014.…”

First report of geophilid centipedes of the genus Ribautia <br />(Myriapoda: Chilopoda: Geophilomorpha) from the Atlantic Forest biome, with description of a new miniature species from Misiones Province, Northeastern Argentina

“…tropica (Brölemann, 1898); and R. silvana Kraus, 1954 (all 14 mm long). Several other occurrences of species with reduced body size are known for the Geophilomorpha; besides the Geophilidae, this is known to occur in some genera of the Aphilodontidae, Ballophilidae, Linotaeniidae, Macronocophilidae, Mecistocephalidae, and Schendylidae (see Foddai & Minelli 1999;Foddai et al 2003;Minelli 2003;Minelli et al 2000;Pereira 2009Pereira , 2011Pereira , 2012Pereira , 2013aPereira , 2013cPereira , 2013dPereira et al 2000;Uliana et al 2007).…”
