Cyathorobbea hypermnestra View in CoL View at ENA , Cy. ruetzleri and Cy. agricola

The dorsal gland opening is positioned roughly at the centre of the corpus in all three species, at around 40–50% of the corpus length ( Figs. 1d View Fig , 2c, d View Fig , 4e, 5g, h, k View Fig and 11c View Fig ). The subventral gland ampullae also have the same position in all three species: at the anterior-most end of the isthmus, anterior to the anterior-most nuclei of the isthmus ( Figs. 5i–l View Fig and 11c, d View Fig ).

in the dorsal sector, they are restricted to the anterior and posterior-most part ( Figs. 1h View Fig , 7f View Fig and 13f View Fig ). In contrast, myofilaments in Cy. agricola are absent in the anterior part of the bulbus and are restricted to the posterior-most end ( Figs. 1i View Fig , 7d View Fig and 13g View Fig ).
