title: [Leptomonas jaculum (Leger, 1902) Woodcock 1914: a leptomonas or a blastocrithidia?].
abstract: Flagellates Leptomonas jaculum, inhabiting the intestine of the water scorpion Nepa cinerea posses promastigote organization, typical of the genus Leptomonas. Nevertheless phylogenetic analysis of the 18S rRNA gene revealed that these trypanosomatids form a common phylogenetic clade with cyst-forming representatives of the genus Blastocrithidia. Morphological characters supporting the unity of the group Blastocrithidia + L. jaculum and the probability of including L. oncopelti in it are discussed.
