'''''Sinocallipus ''''' is a [[genus]] of predominantly cave-dwelling [[millipede]]s in the [[order (biology)|order]] [[Callipodida]]. Five of the six known species are found in limestone caves on the [[Indochinese Peninsula]] from Vietnam to southern China, and it is the only callipodidan genus entirely confined to the [[tropics]].<ref name=StoevEnghoff2011>{{cite journal|last=Stoev|first=Pavel|author2=Enghoff, Henrik |title=A review of the millipede genus ''Sinocallipus'' Zhang, 1993 (Diplopoda: Callipodida: Sinocallipodidae), with notes on gonopods monotony vs. peripheral diversity in millipedes|journal=ZooKeys|date=2011|issue=90|doi=10.3897/zookeys.90.1291|pages=13–34|pmid=21594105|pmc=3084490|doi-access=free}}</ref> Individuals range from {{convert|40-70|mm|in|abbr=on}} long and possess 55 to 70 segments. ''Sinocallipus'' is the sole taxon of the callipodidan suborder '''Sinocallipodidea''', and thought to be the most primitive and [[sister group]] to all other callipodidans.<ref name=StoevEnghoff2011/> In contrast to many other millipede groups, the [[gonopod]]s (reproductive legs) of ''Sinocallipus'' show little variation between species, while other characters such as color, size, and other body parts differ more noticeably between species.<ref name=StoevEnghoff2011/>

==Species== All species except ''S. thai'' have been collected solely from caves, and show [[troglomorphic]] (cave-adapted) traits such as pale coloration, long antennae, and long legs. ''S. jaegeri'' and ''S. simplipodicus'' show reduced eyes, consisting of only 10 to 16 colorless [[Simple eyes in arthropods|ocelli]] each, while the other species have 33 to 50 black ocelli. ''S. thai'' is unique for its dark coloration and terrestrial habitat, and correspondingly has the most ocelli and shortest antennae.<ref name=StoevEnghoff2011/><ref name="Pavel et al 2007">{{cite journal|author=Stoev, P. |author2=Enghoff, H. |author3=Panha, S |author4=Fuangarworn, M |title= A second species in the millipede suborder Sinocallipodidea Shear, 2000 (Diplopoda: Callipodida)|journal=Zootaxa|number= 1450|year=2007|pages= 63–68|url=http://www.mapress.com/zootaxa/2007f/zt01450p068.pdf}}</ref> {||cellspacing=0 cellpadding=4 border=1 style="width: 70%; border-collapse: collapse;" |- |- !bgcolor="#f0f0f0"|Species !bgcolor="#f0f0f0"|Distribution !bgcolor="#f0f0f0"|Notes !bgcolor="#f0f0f0"|Image |- |''Sinocallipus catba'' <br /><small>Stoev & Enghoff, 2011</small> |Vietnam, [[Hai Phong Province]] |Pale yellow body with light brown antennae. |[[File:Sinocallipus catba profile.jpg|200px|center]] |- |''Sinocallipus deharvengi''<br /><small>Stoev & Enghoff, 2011</small> |Vietnam, [[Quảng Bình Province]] |Very long antennae reach past 10th body segment | |- |''Sinocallipus jaegeri''<br /><small>Stoev & Enghoff, 2011</small> | Laos, [[Khammouane Province]] |Eyes inconspicuous and transparent |[[File:Sinocallipus jaegeri habitus.png|200px|center]] |- |''Sinocallipus&nbsp;simplipodicus'' <small> Zhang, 1993</small> | China, [[Yunnan Province]] |Reduced eyes | |- |''Sinocallipus steineri'' <br /><small>Stoev & Enghoff, 2011</small> |Laos, [[Luang Prabang Province]] | |[[File:Sinocallipus steineri profile.png|200px|center]] |- |''Sinocallipus thai'' <br /><small>Stoev, Enghoff, Panha & Fuangarworn, 2007</small> |Thailand, [[Saraburi Province]] |Dark brown body with contrasting white anterior segments and antenna tips |[[File:Sinocallipus thai.jpg|200px|center]] |}
