Taeniarhynchaena micropalamae gen. et sp. n. (Cestoda, dilepididae) from the stilt sandpiper Micropalama himantopus (Bonaparte, 1826).
Taeniarhynchaena gen. n. differs from other genera in its long, cylindrical, proboscidiform rostellum that can be withdrawn and coiled within the rostellar sac. The distal end of the rostellum is expanded and bifid forming two lobes each bearing wrench-shaped hooks peripherally. Other generic characters are the regular alternation of genital apertures, genital ducts dorsal to excretory vessels, testes restricted to posterior moiety of the proglottis, and a persistent uterus. Type species: Taeniarhynchaena micropalamae gen. et sp. n. from the stilt sandpiper Micropalama himantopus (Bonaparte, 1826) taken near Churchill on Hudson Bay, Canada. It is 1.5 to 2.9 mm long with 11 to 16 proglottides. The rostellum 0.45 to 0.5 long and 0.023 to 0.036 mm in diameter has five hooks 0.023 mm long on each lobe. Testes 14 in posterior two-fifths of the proglottis.
