The order Haplobothriidea is a very small, but morphologically peculiar group consisting of one genus and only two described species, both of which parasitize the bowfin (Amia calva L.) in North America (Jones, 1994). The first species of haplobothriidean was described by Cooper (1914a) as Haplobothrium globuliforme Cooper, 1914 on the basis of its possession of a secondary scolex (pseudoscolex) and secondary strobila. The genus Haplobothrium Cooper, 1914 was originally placed in the pseudophyllidean family Dibothriocephalidae Lühe, 1899 (Cooper, 1914a, b). Three years later Cooper (1917) discovered a primary scolex with tentacles and proposed the subfamily Haplobothriinae Cooper, 1917 to accommodate the genus and its single species. At that time, Cooper (1917, pg. 51) noted the resemblance between the tentacles of the primary scolex of H. globuliforme and those of elasmobranch-hosted trypanorhynchs stating “It thus bears a remarkable resemblance to the scolex of the members of the order Trypanorhyncha, which is emphasized by the fact that each proboscis consists of an eversible portion, a muscular bulb for its activation, and a permanently protruded stump, quite comparable morphologically as well as physiologically with the three divisions of the trypanorhynchid proboscis.” Nonetheless, he retained the species and subfamily in the Diphyllobothriidae Lühe, 1910 based on the configuration of the reproductive organs, which resemble those of the Diphyllobothriinae Lühe, 1910.
