E-mail: [email protected] Received: 10 June 2011; Accepted: 20 July 2011 ABSTRACT.– Faunistic records are provided, summarized and mapped for several smaller families of the millipede order Polydesmida in Taiwan. Both Pyrgodesmidae and Opisotretidae are new to the Taiwanese list. The former family is represented there by the nearly pantropical Cryptocorypha ornata (Attems, 1938) which is new to the island’s fauna, as well as by two new species of Ampelodesmus Miyosi, 1956: A. taiwanensis n. sp. and A. similis n. sp.; both latter taxa are incorporated in a key to all five species of the genus. Cryptodesmidae are actually represented in Taiwan by a single, widespread, briefly redescribed and richly illustrated species, Niponia nodulosa Verhoeff, 1931 (= Onomatoplanus simplexus Wang, 1957, n. syn.), while both Opisotretidae and Xystodesmidae by a closer unidentified species of ?Corypholophus Attems, 1937 and Riukiaria Attems, 1938, respectively. In addition to Eutrichodesmus taiwanensis Golovatch, Mikhaljova, Korsós and Chang, 2010, the family Haplodesmidae contains in Taiwan the almost pantropical Prosopodesmus jacobsoni Silvestri, 1910, thus confirming an earlier record.
