“…The current Diplopoda checklist for Laos lists only 34 species (Likhitrakarn et al 2014a), which is probably less than 10% of what can be expected. Indeed, recent taxonomic studies have already added 29 additional species (Likhitrakarn et al 2014a(Likhitrakarn et al , 2014b(Likhitrakarn et al , 2014c(Likhitrakarn et al , 2015a(Likhitrakarn et al , 2015b(Likhitrakarn et al , 2016a(Likhitrakarn et al , 2016bGolovatch 2016aGolovatch , 2016bGolovatch et al 2016aGolovatch et al , 2016bLiu et al 2017a). The record of Diplopoda in Laos is currently limited to species from just seven of the 16 orders.…”

Before this study, giant pill-millipedes (order Sphaerotheriida) were unknown from Laos despite their presence in all surrounding countries. As by-catch from collections by arachnologists, 31 specimens of Sphaerotheriida from Laos became available for study. The sample included 14 species. Three species were only represented by females, which are described but cannot be named. Of the remaining 11 species, a single species belongs to the genus Zephronia Gray, 1832: Z. laotica n. sp.; and the other ten belong to the genus Sphaerobelum Verhoeff, 1924: S. bolavensis n. sp., S. phouloei n. sp., S. denticulatum n. sp., S. spinatum n. sp., S. lachneeis n. sp., S. peterjaegeri n. sp., S. nigrum n. sp., S. splendidum n. sp., S. laoticum n. sp., and S. schwendingeri n. sp. This more than doubles the known diversity of Sphaerobelum. Here, I integratively describe these species, combining morphology and DNA barcodes with a molecular analysis including all Zephroniidae species deposited on GenBank—including the only giant pill-millipede species known from Cambodia, Zephronia dawydoffi Attems, 1953. An updated determination key to the species of the genus is presented. Zephronia laotica n. sp. belongs to the monophyletic Zephronia sensu stricto group, which is confirmed by molecular barcoding. In contrast, most species of Sphaerobelum are in a weakly supported clade. Genetically, Sphaerobelum species differ greatly from one another, with most p-distances >15%. The lowest observed p-distance (9.8%) is between S. truncatum Wongthamwanich et al. 2012 from Thailand and S. peterjaegeri n. sp.

Laos has large areas of primary forest with a largely unexplored fauna. This is evidenced by millipedes, class Diplopoda, with fewer than 60 species being recorded from the country. In the widespread Southeast Asian “Star Millipede” genus Eutrichodesmus Silvestri, 1910 (family Haplodesmidae), only two of 49 recorded species have been found in Laos. Four new species of Star Millipedes are here described from caves in Laos: Eutrichodesmus steineri Liu & Wesener, sp. n., Eutrichodesmus deporatus Liu & Wesener, sp. n., Eutrichodesmus paraster Liu & Wesener, sp. n. and Eutrichodesmus parvus Liu & Wesener, sp. n.. A fifth species, for which only a female is available, remains unnamed. The defensive glands (ozopores) are found to be strongly or entirely suppressed in two of the new species, Eutrichodesmus deporatus Liu & Wesener, sp. n. and Eutrichodesmus paraster Liu & Wesener, sp. n., both troglobionts, which is new to the family. All of the Star Millipedes were collected during Northern Lao-European Cave Project faunal surveys conducted by the Senckenberg Museum, Frankfurt. A key to the six species of Eutrichodesmus currently known to occur in Laos is provided.

Two new species of Glyphiulus are described and illustrated from northern Laos. The epigean Glyphiulus subbedosae Likhitrakarn, Golovatch & Panha, sp. n. is the second member of the granulatus-group to be found in that country and it seems to be especially similar to G. bedosae Golovatch, Geoffroy, Mauriès & VandenSpiegel, 2007. However, it differs from the latter species by a row of several strong setae near the median marginal ridge on the paraprocts, combined with the gnathochilarium being considerably less densely setose on the caudal face, and the anterior gonopods showing a pair of smaller, apical, but larger lateral teeth on the coxosternal plate. Glyphiulus semicostulifer Likhitrakarn, Golovatch & Panha, sp. n. is the fourth member of the javanicus-group to be discovered in Laos, taken from a cave. It seems to be particularly similar to G. costulifer Golovatch, Geoffroy, Mauriès & VandenSpiegel, 2007, but is distinguished by the more sparsely alveolate background fine structure of the metazonae, coupled with the gnathochilarium being considerably less densely setose on the caudal face, much stronger paramedian prongs and 4-segmented telopodites on ♂ coxae 1, the slightly longer and more slender apicoparamedian sternal projections on the anterior gonopods, and the much longer flagella of the posterior gonopods. An identification key to and a distribution map of Glyphiulus species in Laos are also presented.

Review of the millipede genus Kronopolites Attems, 1914 (Diplopoda, Polydesmida, Paradoxosomatidae), with the description of a new species from Laos

Abstract: The millipede genus Kronopolites currently comprises 11 species, including a new species from northern Laos: Kronopolites lunatus sp. n. The generic diagnosis is updated, a key given to all known species, and their distributions are mapped.
