Treatment

Synonyms: Dacnitis Törnquist, 1931 nec Dujardin, 1845; Bulbodacnitis Maggenti, 1971 nec Lane, 1916 Preamble: Choudhury & Dick (1996b) analysed phylogenetically the genus Truttaedacnitis referring inter alia to the morphology and arrangement of the various cephalic plates. Because the homology of some of the cephalic plates could not be determined, these workers did not use the total number of plates in their analysis. Illustrations of the plates in the four species of Truttaedacnitis are given here ( Fig. 86 View FIGURE 86 ).

Generic diagnosis (after Berland 1970). Cucullanidae . Mouth a dorso-ventral slit, directed antero-dorsally, surrounded by cuticular collarette bearing conspicuous or inconspicuous “teeth”. A dorsal cephalic swelling (tubercle) more or less pronounced. Oesophagus with three pairs of longitudinal rods and serrated plates diverging in pseudobuccal capsule, leaving between them thick cuticular plates separated by narrow sutures forming a characteristic pattern. Vulva with conspicuous lips. Male with ventral pre-cloacal sucker. Spicules equal or subequal, straight or bent. Short gubernaculum. Eleven pairs caudal papillae.
