|
Four new species of the genus Amynthas are described from Korea: Amynthas mujuensis sp. nov., Amynthas assimilis sp. nov., Amynthas moakensis sp. nov., and Amynthas sangumburi sp. nov. The intestinal caeca are of simple type and genital markings lacking in all four species. Amynthas mujuensis sp. nov. has male field with large oval papillae, each papilla with longitudinal seminal groove; paired spermathecal pores present in 6/7, 7/8 dorsally. Amynthas assimilis sp. nov. has male field composed of paired symmetrical pear?shaped pads with broad ends laterally, axes of symmetry diagonally oriented towards posterior; spermathecal pores in 5/6, 6/7. Amynthas moakensis sp. nov. has male pores on small porophores surrounded by swollen concentric furrows, with the spermathecal pores in 6/7, 7/8, 8/9, ventrally. Amynthas sangumburi sp. nov. has male pores centered on 0.8 mm circular flat porophores, with the spermathecal pores in 5/6, 6/7, 7/8, 8/9, late rally.
