Abstract
The present paper represents some taxonomie notes on the genera Centrodesmus Po-cock 1894 and Pratinus Attems 1937. It is found that the two Chinese known species, C. longispinus Loksa 1960 and C. cornutus Zhang 1982, should be placed in the Pratinusand to it should be assigned also two new species which are described as follows.Pratinus minutuberosus, sp. nov. (figs. 1-7)Eolotype ♂ (810410-1), allotype ♂ (810410-2), paratypes 2♀♀ (810410-3, 4), from Tianlin County, (24° N,. 106° E),, Guanxi Zhuang Autonomous Kegion, on Nov. 27.1978.Length 25 nim in male and 27 mm in female. Body colour, yellow.Head somewhat wider than collum. Metatergite not only with normally disposed ser tiferous tubercles, but also with a row of similar tutereles along the posterior rim. Ster-nite of the 5th segment with a rather wide and short prwess between the amterior legs, which bears a short longitudinal furrow on the ventral surfaoe and a slight incision at the posterior margin. Gonopod with the femur bent moderately backward and the. ti-biotarsus rather short, eoiled from. lateral to snedial side along the dorsal surface and with two laminellae at the end.The new species is closely related to Pratinus longispinus, but it is distinguishedfrom the latter by a process on. the femur of the 6th instead of the ,5th legPratinus raatrituberous, sp. nov. (figs. 8-14)Holotype ♂ (830916-l), allotype ♀ (830916-2), paratypes ♂ (830916-3) 2♀♀ (830916-4, -5) from Mangshi, Lusi County (24° N, 98° E);Yunnan Province, on July 22, 1983.Length 20mm in male and 22mm in female. Body colour blackish brown,Collum slightly wider than head. Legs of anterior foody without any modifications, but the femur of the 5th and 6th legs slightly swollen. 5th sternite with two processes. between anterior legs; the anterior one squarish and produced forward; and the poste-rior one a swelling produced slightly cauded and bearing two pores. Gonopod with the femur relatively slender and ereet, but becoming stout .distally, and the lamins latera-lis of tibiotarsus somewhat reduced, the lamina medialis with a narrow furrow suppor-ting the solenomerite and two latninellae at the end.The new species reserables Pratinus teras Jeekel. 1964 in the sfeape of keels, but dif-fers from it in the stouter tubereles at posterior transverse row and the process on ster-nite of 5th segment.All the type speamens of the two new species are preserved in the Institute of Zoology, Aeademka Sinica.

Based on all available information, 339 species from 71 genera, 26 families, and eleven orders of Diplopoda have hitherto been recorded from mainland China, the fauna thus being very rich, albeit far from completely known, comprising various zoogeographic elements and populating very different environments. Diplopods mainly occur in various woodlands, in caves, and high in the mountains. Most species (> 90 %, usually highly localised, including 160 cavernicoles), 18 genera, and one family are st...

: The dragon millipede genus Desmoxytes s.l. is split into five genera, based on morphological characters and preliminary molecular phylogenetic analyses. The present article includes a review of Desmoxytes s.s., while future articles will deal with Hylomus Cook and Loomis, 1924 and three new genera which preliminarily are referred to as the 'acantherpestes', 'gigas', and 'spiny' groups. Diagnostic morphological characters of each group are discussed. Hylomus is resurrected as a valid genus and ...

Four new species of Desmoxytes are described from southern China: Desmoxytes lingulata sp. n., Desmoxytes parvula sp. n., and Desmoxytes nodulosa sp. n., from Guangxi Zhuang Autonomous Region, and Desmoxytes getuhensis sp. n. from Guizhou Province. In addition, new records of Desmoxytes scutigeroides Golovatch, Geoffroy & Mauries, 2010 and Desmoxytes scolopendroides Golovatch, Geoffroy & Mauries, 2010 are provided, with a modified key to Desmoxytes species currently known to occur in China. Two ...

The large Southeast Asian genus Desmoxytes is slightly rediagnosed. A number of troglomorphic, most likely troglobitic, species occur in southern China. A key is provided to all 10 Desmoxytes spp. currently known from China, including three new presumed troglobites: Desmoxytes eupterygota sp. n. from Hunan Province, as well as Desmoxytes spinissima sp. n. and Desmoxytes lui sp. n. from Guangxi Province. “Desmoxytes” philippina Nguyen Duc & Sierwald, 2010, from the Philippines, is formally remove...

A new dragon millipede species, Desmoxytes philippina, from the Philippines is described. This fi rst Philippine dragon millipede species expands the previously known distribution of the group, from Southeast Asia (Desmoxytes Chamberlin, 1923) and Australia (Desmoxytoides Mesibov, 2006).
