Genus Phaneromerium Verhoeff, 1941

Type species: Cryptogonodesmus obtusangulus Carl, 1914 , from Colombia, by subsequent designation of Verhoeff [1941] .

Other species included: P. laticeps ( Kraus, 1954) , P. longipes ( Kraus, 1954) , P. minimum ( Kraus, 1954) , P. robustum ( Kraus, 1955) , P. taulisense ( Kraus, 1954) , all from Peru, P. distinctum Golovatch, 1994 , P. latum Golovatch, 1994 , P. minutum Golovatch, 1994 , all three from near Manaus, Brazil, P. cavernicolum Golovatch et Wytwer, 2004 , and P. troglopterygotum Golovatch et Gallo , in Golovatch et al., 2022, both latter species being troglobionts from Bahia, Brazil [ Carl, 1914; Verhoeff, 1941; Kraus, 1954, 1955; Golovatch, 1994; Golovatch, Wytwer, 2004; Golovatch et al., 2022]. Most species of the genus have been keyed [ Golovatch, Wytwer, 2004].

DIAGNOSIS. To slightly extend the earlier characterization [ Golovatch et al., 2022], this is one of the basalmost genera of Trichopolydesmidae with relatively little enlarged gonopod coxites that form together no considerable gonocoel cavity, but support instead almost fully exposed, suberect and relatively simple to complex telopodites, uni-, bi- or tripartite, held parallel to each other [ Golovatch, 1994]. This condition is deemed to be the most primitive in the gonopodal evolution of Neotropical Trichopolydesmidae compared to the developments observed in the remaining eight recognized genera that occur in the region [ Golovatch, 1992, 1994; Golovatch, Wytwer, 2004].
