Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="cbin10449-sec-0001" sec-type="section"> <p>Spermatological characteristics are described for the first time in the genus <italic>Neomultitestis</italic> Machida, 1982, belonging to the family Lepocreadiidae Odhner, 1905. Adult <italic>Neomultitestis aspidogastriformis</italic> were collected from the digestive tract of <italic>Platax teira</italic>, caught off New Caledonia. The mature spermatozoon of <italic>N. aspidogastriformis</italic> is described by transmission electron microscopy (TEM). It includes two axonemes with 9 + "1" pattern of Trepaxonemata, an antero‐lateral electron‐dense material, attachment zones, two mitochondria, a nucleus, two bundles of parallel cortical microtubules, external ornamentation of the plasma membrane, spine‐like bodies, and granules of glycogen. Certain ultrastructural characteristics of the spermatozoon, especially the antero‐lateral electron‐dense material, are shared by <italic>N. aspidogastriformis</italic> and all species of the superfamily Lepocreadioidea studied so far. The antero‐lateral electron‐dense material, present in different families of lepocreadioids, supports the monophyletic status of the superfamily. We also list several ultrastructural characteristics which characterize the mature spermatozoon of the Lepocreadioidea.</p> </sec> </abstract>
