When he described the genus Octodesmus , Lesne (1901) did not designate a type species. Fisher (1950) designated Octodesmus episternalis Lesne as the type species. The name is based on a series of syntypes in several museums ( Lesne 1901 ). The senior author has examined syntypes of the species in MNHN. Amongst them is a specimen labelled as lectotype by J.M.Vrydagh, but the designation was never published. In order to fix the identity of the species, we here designate this specimen as lectotype . It bears the labels: “Carin/Asciuli Cheba/ 1200-1300m /L. Fea I-88//³// Octodesmus / episternalis Lesne / type P. Lesne vid.// LECTOTYPE /J.M. Vrydagh”. Both Lesne (1901) and Fisher (1950) note that this is the only known species of Bostrichidae in which the inner margin of the metepisternum is convex towards the ventral midline.
