Type material examined. Lectotype of Eophileurus felschei Prell, 1913 (♀, MFNB, Figs. 38–41), labeled: “ GENJI 25 août – 15 sept 1901 // COROMANDEL M. MAINDRON // Eophileurus felschei Prell ♀ - Type // Lectotypus Eophileurus felschei Prell SEndrődi”. Paralectotype of E. felschei Prell, 1913 (♂, MTD, Figs. 42–48), labeled: “Sum.

Remarks. Eophileurus felschei Prell, 1913 was described based on one pair of specimens from “Genji, India ”. The lectotype (Figs. 38–41) was designated by Endrődi (1977), which is the female specimen housed in MFNB. The paralectotype (Figs. 42–48) of this species is the male specimen housed in MTD. In recent years, Dupuis (2014) described E. grossepunctatus Dupuis, 2014 from “Shimoga, India ” (Holotype: Figs. 49–53) without providing any comparison to E. felschei. After the examination of the type material of both taxa, it is clear that no major differences are present in both the appearance and the parameres other than slight differences on the lateral processes of the parameres of the two male types (the lateral processes are slightly more enlarged and expanded at their apices in the type of E. felschei and less so in E. grossepunctatus. This mild difference can be seen in Fig. 46 versus Fig. 52 for the front view, and Fig. 47 versus Fig. 51 for the lateral view). Following the conclusion of the discussion section at the end of this paper, it is observed that the lateral processes bare the largest individual and geographical variations, and with differences this mild, the differences are too insignificant to separate them from a single species. Hence, E. grossepunctatus is conspecific with E. felschei and thus synonymized here.
