A new Oriental species of the genus Sphaeridium Fabricius, 1775, S. daemonicum sp. nov., is described based on specimens recently collected in the Brahmaputra valley (lowland part of Arunachal Pradesh, India) and historical specimens from southern Myanmar. The new species differs from all other described Oriental species by its wide parameres partly enveloping the median lobe, small body size, and coloration of the body. It is unique among Oriental species by the presence of a series of small spines along the lateral margin of pronotum and elytra. In the latter character, it resembles the members of the Afrotropical S. simplicipes group.
