FIGURE 15 in Description and taxonomic analysis of a tuberculated turtle leech from the Outer Banks, North Carolina, USA, provisionally identified as Placobdella multilineata Moore, 1953 (Hirudinea: Glossiphoniidae)

FIGURE 15. The multilinear pattern of dorsal tubercles in the Albemarle turtle leech correlates with the underlying crop caeca. For comparative purposes the intermediate tubercle (ti) of segment XIX is labelled in each respective image. A, orderly pattern of five rows of dorsal tubercles of an adult individual (PM-6). B, same individual as A under intense transmitted light showing the respective dorsal tubercles in relation to underlying blood-filled crop caeca. C, unfed embryo (4.8 mm) brooded by the adult in A, B, showing presumptive tubercles linked to the same respective crop caeca. A, reflected LED light. B, C, transmitted LED light. Scale bars: A, B, 5.0 mm; C, 0.2 mm.
