Research of Retinometra longivaginata (Fuhrmann, 1906) and R. longicirrosa
(Fuhrmann, 1906) showed the presence of a morphologically peculiar ring, ca
lled ad hoc praeputium ciri, situated on the protruded cirrus of both speci
es. This tegument has also been observed in the revised type specimen of Hy
menolepis longivaginata Furmann, 1906. Moreover, data on inadequately studi
ed characters have been expanded. The two species are registered iu Slovaki
a for the first time.
The findings are discussed morphologically and taxonomically, mainly in rel
ation to the genera Retinometra Spassky, 1955 and Cladogynia Baer, 1937.
