Placobdelloides stellapapillium

External morphology

three annulate with a maximum relaxed length of 17 mm and width of 5 mm (N=10). The dorsal surface has 12–14 star-shaped papillae on the dorsal sur face of each annulus. Star-shaped papillae are typic ally larger and more pronounced on a2 annuli than on a1 or a3 annuli. Additional minute cone-shaped papillae may occur between the larger star-shaped papillae or may replace these papillae on a1 and a3 annuli. When preserved in 10% formalin, the dorsal surface is green in colour, but pigment is lost when preserved in 70% ethanol. The ventral surface is transparent
