5B513F7ACF1BDABDFCACC19D91806155.taxon	diagnosis	Diagnosis. Acanthobothrium soniae sp. nov. is a Category 2 species. It is small, with a range of 10 - 13 acraspedote proglottids. The testes are wider than long with a range of 31 - 47 testes per proglottid. The arms of the ovary are unequal (asymmetrical). Finally, this species also can be distinguished from similar congeners by total length, number of proglottids, diameter of accessory sucker, the length of the cirrus sac, number of testes per proglottid, and size of the hooks.	en	Zaragoza-Tapia, Francisco, Pulido-Flores, Griselda, Violante-Gonzalez, Juan, Monks, Scott (2019): Two new species of Acanthobothrium Blanchard, 1848 (Onchobothriidae) in Narcineentemedor Jordan & Starks, 1895 (Narcinidae) from Acapulco, Guerrero, Mexico.
