A new species of the hermit crab genus Diogenes Dana, 1851, D. spongicola, is described and illustrated on the basis of material collected from two locations off southern India. It appears close to D. takedai Rahayu, 2012 among about 70 congeners, but easily differentiated from the latter by the spinulose anterolateral margins of the shield, the article 2 of the antennal peduncle armed only with one distal spine, the longer, spinose antennal acicle, the absence of prominent spines on the ventrolateral margin of the cheliped meri, and the different color of the cheliped palm. Specimens of the new species were all collected from cavities of a callyspongiid sponge Callyspongia diffusa (Ridley, 1884), suggesting a possible association between the hermit crab and sponge.
基于从印度南部沿海两个地点采集的材料，描述并图示了寄居蟹属（Diogenes Dana，1851）的一个新物种——海绵寄居蟹（D. spongicola）。在约70个同属物种中，它似乎与2012年发现的武田寄居蟹（D. takedai Rahayu）相近，但很容易通过以下特征与后者区分开来：头胸甲前侧缘具小刺，触角柄节第2节仅具1个远端刺，触角鞭节较长且具刺，螯足 meri腹侧缘无突出的刺，以及螯足掌节颜色不同。新物种的标本均采自一种钙质海绵——扩散管海绵（Callyspongia diffusa，Ridley，1884）的腔室中，这表明该寄居蟹与海绵之间可能存在某种联系。
