Species of the superfamily Dracunculoidea have neither lips nor valves; the round mouth is enclosed in a thin circumoral membrane, on the outside of which cuticularized protuberances may be present (Dracunculus, 9 Av i ? s e r p ens ) or absent (Philometra, Micropleura) (Figure 2). The inner ring of papillae is well developed; the outer ring consists of eight papillae. In Micropleura and Philometra all the papillae are dis- tinctly developed, while in Dracunculus and Avioserpens the median papillae of the outer ring are partly fused. In Dracunculus the interoventral and interodorsal papillae become fused in the female during development, but in the male the papillae maintain the normal arrangement. Species of Dracunculidae have a thickened cuticular shield which projects anteriorly, forming a circumoral protuberance, and it surrounds the anterior end of the esophagus posteriorly. The genus Dracunculus differs from Avioserpens in the presence of a cuticular ring around the mouth on the cephalic shield characteristic for both FIGURE 2.
