Abstract

The Eulichas dudgeoni species group of the genus Eulichas Jacobson, 1913 is revised. Three informal species complexes are established. All included species are described and their diagnostic characters are illustrated. The following eleven new species are described: E. alesbezdeki Hájek, sp. nov. (Laos, Vietnam), E. jakli Hájek, sp. nov. (Indonesia: Kalimantan), E. oborili Hájek, sp. nov. (Thailand), E. robusta Hájek, sp. nov. (Malaysia), E. sausai Hájek, sp. nov. (Indonesia: Sumatra, Malaysia), E. serricornis Hájek, sp. nov. (Malaysia), E. siamensis Hájek, sp. nov. (Laos, Thailand, Vietnam), E. similis Hájek, sp. nov. (Laos, Thailand), E. sundaensis Hájek, sp. nov. (Indonesia: Sumatra, Java), E. villosa Hájek, sp. nov. (Malaysia: Sabah), and E. wewalkai Hájek, sp. nov. (Nepal). E. baeri (Fairmaire, 1898) is synonymised with E. baeri var. innotatus Pic, 1924 syn. nov. Lectotypes are designated for Eulichas baeri innotatus (Luzon, Philippines), E. incisicollis Pic, 1933 (Cameron Highlands, Malaysia), and Lichas subocellata Fairmaire, 1898 (Kinabalu, Sabah, Malaysia).
