In addition to two species of the diplopod family Cryptodesmidae already reported from Indochina, Trichopeltis kometis (Attems, 1938) and Ophrydesmus anichkini Golovatch, 2015, the fauna of that region is supplemented by three species: Niponia nodulosa Verhoeff, 1931, a millipede hitherto known only from southern Japan and Taiwan, is now recorded from Vietnam; Trichopeltis cavernicola sp. n. from Laos, the sixth species in that tropical Asian genus, is the first presumed troglobite to be described amongst the Asian cryptodesmids and shows several distinct troglomorphic features; and Circulocryptus gen. n., monobasic, which joins the tribe Dyakryptini, but differs from all three contribal genera (two monobasic from Borneo, and another, oligotypic, from New Guinea) primarily in the gonopods of Circulocryptus faillei sp. n., from Vietnam, being especially elaborate and subcircular, the telopodites strongly twisted, and the solenomere lying much more basally.

The diversity of Diplopoda in caves of southern China is remarkably high, often 5-6 species per cave, consisting mostly of local endemics and presumed troglobionts. These are evidently biased to just a few lineages, mainly members of the orders Chordeumatida and Callipodida, the families Cambalopsidae (Spirostreptida) and Haplodesmidae (Polydesmida) or the genera Pacidesmus, Epanerchodus and Glenniea (all Polydesmida, Polydesmidae), Trichopeltis (Polydesmida, Cryptodesmidae), Dexmoxytes (Polydesmida, Paradoxosomatidae) and Hyleoglomeris (Glomerida, Glomeridae). All these taxa, especially the Paradoxosomatidae and Cambalopsidae (usually amounting to about 60% and 10% of the total species diversity in the Oriental fauna, respectively), are moderately to highly speciose across Southeast Asia, being largely epigean.

Surface structures have rarely been the subject of a comprehensive study in Polydesmida despite their tremendous variety within this order. A number of these peripheral structures are here studied in most families of the suborders Polydesmidea and Dalodesmidea (sensu Hoffman 1980), using scanning electron microscopy. An illustrated description of the surface sculpture of the prozonite, the limbus and the intercalary cuticular micro-scutes on the metazonite is given for the first time for the studied families, together with an account of some other poorly known surface structures.
