Cercariae of bird schistosomes are traditionally considered to be very similar in their morphological characteristics. In order to solve the problem, we tested some methods which might be suitable for cercarial differentiation. Fourteen isolates of three Trichobilharzia species (T. szidati, T. franki, T. regenti) occurring sympatrically in Central Europe were used. Dimensions of individual cercariae do not represent a useful criterion for identification, because the intraspecific variability exceeds the interspecific one. On the other hand, chaetotaxy appears a promising way for discrimination, although some sensory papillae do not stain sufficiently with silver nitrate. The papillary pattern (i.e. number and relative position of papillae) is specific for all Trichobilharzia species studied by us. Therefore, we compiled an identification key for the three Trichobilharzia species. In addition, we tried to find species-specific surface saccharide epitopes; none of the labeled lectin probes can be used as a speciesspecific marker.

nr 2

The first and last instars of Isturgia roraria (Fabricius, 1777) caterpillars are described and illustrated in details. The mouthparts, antennae and thoracic legs are used for the first time for the description within the genus Isturgia (Hübner, 1823). The description and complete illustration of thoracic leg of adult larva with numeration and nomenclature of all pores and setae are included. Some important characters of intermediate larval instars are recorded. New morphological details of pupa are presented.

nr 3

Juvenile stages of Punctoribates punctum (C. L. Koch, 1839) and P. hexagonus Berlese, 1908 are redescribed, those of P. sellnicki Willmann, 1928 are described for the first time, and both juveniles and adults of all species are illustrated. The juvenile stages of these species are similar in body shape and the number of setae on the prodorsum, gastronotum and anal, anogenital and epimeral regions, but differ in the shape and length of some prodorsal and gastronotal setae. Keys to the larvae and nymphs of these species are prepared.
