Tapas Chatterjee and Cheon-Young Chang (2007) Two new halacarid species of the genus Agauopsis (Acari: Halacaridae), collected from South Korea, are described. Both species belong to the A. brevipalpus group. Agauopsis ivanomorsellii sp. nov. is characterized by an “H”-shaped areola on the anterior dorsal plate (AD), the posterior dorsal plate (PD) with 4 costae, dorsal setae-4 situated on the PD, telofemur I with a ventral and 2 ventromedial spines, the female genitoanal plate (GA) slightly arched anteriorly, and the male GA truncated anteriorly. Agauopsis youngilensis sp. nov. is characterized by an“M”-shaped areola on the AD, a PD with 4 costae, 2 ventral and 2 ventromedial spines on telofemur I, the male GA slightly arched anteriorly, and the female GA anteriorly truncated or slightly arched. Dissimilarities with related species are discussed.
