Dinogeophilus

Dinogeophilus is a genus of soil centipedes in the family Schendylidae. This genus contains only two species, Dinogeophilus pauropus and D. oligopodus, which range from in length. These species are notable as the smallest not only in the order Geophilomorpha but also in any epimorphic order of centipedes. The species D. oligopodus is also notable as one of only six species of soil centipedes to feature only 29 pairs of legs and one of only two species to include females with only 29 pairs, the minimum number recorded for females in the order Geophilomorpha.

== Discovery and distribution == This genus was created by the Italian entomologist Filippo Silvestri in 1909 to contain the newly discovered type species D. pauropus. This species is known from only one specimen, a male collected near Salto, along the Uruguay river, in Uruguay. In 1984, the zoologist Luis Alberto Pereira described the second species in this genus, D. oligopodus, based on five specimens collected near Puerto Iguazu, close to the Paraná river, in the Missiones province of Argentina. These specimens include a male holotype, three male paratypes, and one female allotype. Since the original description of D. oligopodus, Pereira and three biologists from the University of Padua (Lucio Bonato, Alessandro Minelli, and Leandro Drago) examined seven more specimens (two males and five females) collected from La Plata in Argentina. All thirteen specimens of this genus are adults or at least subadults, based on an examination of the size and shape of the gonopods. All specimens of the genus have been found in a small region of South America, straddling Uruguay and Argentina, between the northern Pampas and the Brazilian Highlands, in the middle and lower part of the basin of the Uruguay and Paraná rivers.
