Meggiorini, 1 &amp;female; (MNHN JC 314). <b>Name.</b> To emphasize the deeply incised caudolateral lobulations on most metaterga. <b>Diagnosis.</b> Differs from all congeners by the unusually deeply incised caudolateral and lateral lobulations on most of the metaterga, as well as the peculiar, biramous, multituberculate, midway, lateral process (dp) of the gonopod telopodite. <b>Description.</b> Length of adults of both sexes <i>ca</i> 7-8 mm, width 1.1-1.2 mm, body broadest at segments 3 and 4. Holotype <i>ca</i> 7 mm long and 1.2 mm wide. Coloration rather uniformly whitish to light yellow, anterior body parts often a little infuscate, light yellow-brownish. Adults with 20 segments (Fig. 22A), conglobation pattern typical of “ Doratodesmidae ”, complete. Head (Fig. 23B) basically as in preceding species, but tegument slightly rougher (Figs 24A, B, D-F), antennae somewhat shorter (Fig. 23B), collum not covering head from above, regularly convex, with four rows of high, conical tubercles (Figs 22B, E). Metaterga behind collum with three transverse, rather regular rows of similarly high tubercles, most of which still retain very short, bisegmented setae (Fig. 22; 24E, F); limbus microcrenulate. Paraterga mostly directed ventrolaterad, strongly declivous, narrow, tips clearly surpassing the level of venter, unusually distinctly crenulate/lobulate laterally and caudolaterally, usually with characteristic, deep incisions between lobules (Figs 22; 23E, F); paraterga 2 strongly enlarged, subvertical, anterolateral and lateral margins both evidently trilobate, caudal margin above schism with 4-5 similarly evident lobules, both schism and hyposchism small; paraterga 3 and 4 slightly shorter than others, bilobate laterally (Fig. 22B), following paraterga broadly rounded and mostly evidently trilobate, overlap typical. Pore formula normal, ozopores located near base of ventrocaudal lobulation (Fig. 23F). Pleurotergal carinae wanting. Epiproct strongly flattened, dorsally also tuberculate, with several deep incisions at lateral edge, directed ventrocaudad, with the usual four cones just below tip; para- and hypoprocts as in Figs 23A, D. Sterna usually with a rather deep, narrow depression between coxae (Fig. 24C), only those between coxae 6, 7 and 9 much wider (Fig. 25A). Gonopod aperture transverse-oval, relatively small, far from reaching lateral sides of segment 7. Legs rather short; femoral and tarsal segments equal and longest; several basal segments microtuberculate; claw simple, slightly curved ventrad; some setae very sparsely microdenticulate (Fig. 24C). Gonopods (Figs 25A, B) relatively complex. Coxae subquadrate, large, microtuberculate and abundantly setose ventrolaterally, with a conspicuous triangular lobe frontolaterally. Telopodite considerably longer than coxite, unciform, rather slender, setose in its basal half, with a conspicuous, biramous, microtuberculate, distofemoral process (dp) laterally at about midway, more distally with a slightly folded acropodite bearing several small outgrowths, but devoid of a hairpad; seminal groove terminating subapically. <b>Remarks.</b> <i>Glyphiulus latellai</i> Golovatch, Geoffroy, Mauriès &amp; VandenSpiegel, 2007 is another millipede recorded from Tiao Shuz Dong and Shu Jia Yan caves (Golovatch et al. 2007a), whereas Liao Jing Ling Dong Cave contains the subcosmopolitan <i>Oxidus gracilis</i> (C. L. Koch, 1847) (Geoffroy and Golovatch 2004).
