FIGURE 11 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 11. The last three body segments (XXV–XXVII) of the Albemarle turtle leech constitute the peduncle. A, specimen (PM-21a) showing typical configuration of pre-anal tubercles (pt1–pt3), a characteristic of this species. B, atypical specimen (PM-1a) with a distinctive narrowing of the peduncle as fixed during extension of the body. C, D, under ultraviolet light. C, fluorescence restricted to margins of this specimen (PM-14b). D, fluorescence primarily confined to tips of the pre-anal tubercles in this specimen (PM-14d). Scale bar: 1.0 mm.
