Abstract
A new species, Sclerocardius lyali sp. nov., is described and illustrated from Mae Hong Son Province, Thailand. The new species is close to Sclerocardius indicus Hartmann, 1903, but differs in the body covered with short setiform yellowish and pale scales, the postero-ventral side of the protibia lacking teeth, a pronotum with quite large punctation, and a narrower aedeagus. This is the first record of Sclerocardius Schoenherr, 1847, from Thailand. A key to Asian species of the genus Sclerocardius is also given.

Diagnosis. This new species is closely related to Sclerocardius indicus Hartmann, 1903, but differs in that it has short setiform yellowish and pale scales on the body, a postero-ventral side of the protibia without teeth, a pronotum with quite large punctation, and a narrower aedeagus. Sclerocardius indicus is characterised by a body covered in long, narrow, orange scales; a pronotum with relatively small punctation; a postero-ventral side of the protibia with three rounded teeth; and the aedeagus is also wider.
