The genus Ashworthius contains the following species: A. pattoni Le Roux, 1930 (genotype) from Tragelaphus scriptus sylvaticus (bush buck), A. sidemi Schulz, 1933 from Cervus nippon hortilorum (Sika deer) and C. elaphus asiaticus (red deer), A. martinagliai Ortlepp, 1935 from Bosclaphus tragocamelus (Nilgai) and A. lerouxi Diaouré, 1964 from Syncerus coffer nanus (dwarf forest buffalo). Pike (1969) revised the genus and redescribed A. lerouxi from Syncerus caffer coffer (African buffalo). He gave accounts of other valid species and amended the generic diagnosis.
