§ Omorgus (Haroldomorgus) batesi (Harold, 1872)

Trox batesi Harold 1872: 126 (Brazil - LECTOTYPE)

Distribution. Brazil (NA): Blackwelder 1944: 218 (as Trox batesi); Vaurie 1962: 154 (as Trox batesi) (NA); Scholtz 1990: 1418 (designation LECTOTYPE Trox batesi) (NA); Zídek 2013: 7, 2017: 98. “Amazon Basin”: Harold 1872: 126 (as Trox batesi); Arrow 1912: 54 (as Trox batesi). Other: Vaurie 1962: 154 (Argentina, Paraguay - as Trox batesi); Scholtz 1990: 1418 (Argentina); Zídek 2013: 7 (Argentina, Paraguay), 2017: 98 (Argentina, Paraguay).

Note. It is unclear to us why and how Scholtz (1990: 1418) designates a lectotype of Omorgus batesi from the ISNB, as Vaurie (1962: 154) explicitly reports to have examined the type in the MNHN. Harold (1872: 126) mentions only a single specimen in his description. We consider the validity of the lectotype questionable.
