The millipede genus <i>Cryptocorypha</i> Attems, 1907 revisited, with descriptions of two new Oriental species (Diplopoda: Polydesmida: Pyrgodesmidae)
The largely Old World, tropical or subtropical diplopod genus Cryptocorypha Attems, 1907 is reviewed, with the following three new formal generic synonyms established: Carlodesmus Verhoeff, 1941, Cryptomauritius Verhoeff, 1941 and Sisyrodesmus Attems, 1912, all syn.n. Two species are newly synonymized: C. fungifer (Attems, 1953), comb.n. (= C. leleupi Golovatch, Nzoko Fiemapong et VandenSpiegel, 2017), and C. riparia (Carl, 1932), comb.n. (= C. lawrencei (Verhoeff, 1941)), both syn.n. Another two new species are described: C. bicolorata sp.n. from Laos and C. jaegeri sp.n. from northern Thailand. A provisional key is compiled to all 25 currently recognized species of Cryptocorypha , including two old congeners, C. tobana Chamberlin, 1945, from Sumatra, Indonesia and C. leia Chamberlin, 1945, from Java, Indonesia, based on a revision of their holotypes.
