A new Lucanidae of the genus Macrodorcas Motschulsky, 1861 from Thailand, Chantaburi province, Soi Dao district is described. The new species has the typical appearance presented by other species of the genus Macrodorcas but can be separated significantly. Macrodorcas kesininae spec. nov. has been compared by external morphology and by male genitalia with the related species Macrodorcas pseudaxis (Didier, 1926) and Macrodorcas virginiae (Bomans, 1991) which are represented also in Thailand to substantiate the hypothesis of a new species of the genus Macrodorcas.

Key words: Coleoptera, Lucanidae, Macrodorcas, Macrodorcas kesiniae, Chantaburi, Thailand, new species
