A new species of Lentiella (Cestoda: Anoplocephalidae) from Proechimys simonsi (Rodentia: Echimyidae) in Bolivia

Abstract

DURING A BIODIVERSITY SURVEY OF MAMMALS AND THEIR PARASITES IN THE BENI, BOLIVIA IN THE SUMMER OF 2000, SEVERAL SPINY RATS, PROECHIMYS SIMONSI THOMAS, 1900, WERE COLLECTED AND EXAMINED FOR PARASITES. HEREIN WE DESCRIBE LENTIELLA LAMOTHEI N. SP. FROM ONE OF THESE HOSTS. THIS SPECIES IS CAN BE DISTINGUISHED FROM L. MACHADOI RÚGO, 1964 BY HAVING A GREATER TOTAL LENGTH BUT SMALLER MAXIMUM WIDTH, A GREATER NUMBER OF SEGMENTS, A SMALLER CIRRUS SAC, A SMALLER SCOLEX DIAMETER, AND IN THE EGGS, A LARGER PYRIFORM APPARATUS. IN ADDITION, WE FORMALLY VALIDATE THE GENUS LENTIELLA RÚGO, 1964, THAT HAD BEEN PLACED IN SYNONOMY WITH MONOECOCESTUS BEDDARD, 1914.
