A new species of diogenid hermit crab, Diogenes minimus, is described and illustrated on the basis of material from shallow subtidal waters (5-19 m) in central Japan. It appears close to D. holthuisi Asakura Tachikawa, 2010, but easily distinguished from the latter by the shape of the antennal acicle, non-elongate male left cheliped and the armature of the right cheliped merus. Including the new species, 14 identified species of Diogenes are now known from Japanese waters. A brief overview on species of Diogenes recorded from Japanese waters is given.
基于来自日本中部浅潮下带水域（5 - 19米）的材料，描述并图示了一种新的戴奥真寄居蟹物种——微小戴奥真寄居蟹（Diogenes minimus）。它看起来与2010年朝仓立川发现的霍尔修斯戴奥真寄居蟹（D. holthuisi）相近，但通过触角刺的形状、雄性左螯足不细长以及右螯足 merus 的装甲，很容易与后者区分开来。包括这个新物种在内，目前已知有14种已鉴定的戴奥真寄居蟹物种来自日本水域。文中还对日本水域记录的戴奥真寄居蟹物种进行了简要概述。
