Abstract: 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.
