A taxonomic study of the Indian species of Euops Schoenherr (Coleoptera: Curculionoidea: Attelabidae)

摘要

The Euops species of India excluding the Himalaya region are revised. Seven species are recorded from the area, placed in three subgenera (Parasynaptopsis Legalov, 2003 stat. n., Flavoriedeliops Legalov, 2003 stat. n. and Riedeliops Alonso-Zarazaga &Lyal, 2002) as follows: E. (Parasynaptopsis) andrewesi Voss, 1935, E. (Flavoriedeliops) tamilnadunsis Legalov (2003), E. (Riedeliops) bowringii Jekel, 1860, E. (Riedeliops) indicus (Legalov, 2004), E. (Riedeliops) keiseri Voss, 1957, E. (Riedeliops) pseudoindicus sp. n. and E. (Riedeliops) trichinopoliensis (Legalov, 2007). Diagnoses are provided for the subgenera E. (Parasynaptopsis) and E. (Flavoriedeliops) and a description for E. (Riedeliops). The genera Asynaptops Legalov, 2007, Nigroeuops Legalov,2003, Orienteuops Legalov, 2003 and Sawadaeuops Legalov, 2003 are downgraded to subgenera and synonymised with E. (Riedeliops) (syn. n.), as are the subgenera Asynaptopsis Legalov, 2007 and Orienteuopsidius Legalov, 2008 (syn. n.), while the genera Indoeuops Legalov, 2007, Morphoeuops Legalov, 2003 are synonymised with E. (Parasynaptopsis) (syn. n.). Euops bowringii Jekel, 1860, E. indicus (Legalov, 2004) comb, n., E. keiseri Voss, 1957, E. rasuwanus (Legalov, 2003) comb. n. and E. trichinopoliensis (Legalov 2007) comb. n. are transferred to E. (Riedeliops) and E. andrewesi Voss, 1935 to E. (Parasynaptopsis) (new placements). The following new synonymies are proposed: Euops andrewesi Voss, 1935 (= E. ammattiensis (Legalov, 2007) syn. n.); Euops bowringii Jekel, 1860 (= E. armipes Voss, 1933 syn. n., E. submetallicus Voss, 1935, syn. n., Asynaptops (Asynaptopsis) colombensis Legalov, 2007, syn. n.); Euops (Riedeliops) rasuwanus (Legalov), 2003 ( = Parasynaptops bengalensis Legalov, 2007, syn. n.). Lectotypes are designated for the names E. andrewesi, E. bowringii, E. armipes and E. submetallicus. One new species, E. pseudoindicus sp. n., and one new subspecies, E. keiseri nilgiriensis ssp. n., are proposed. All species are described or redescribed indetail, primary types and relevant characters are illustrated, a key to the species is provided and the distributions of the species are mapped.
