| Sumario: |
Parasitological examination of a stranded hawksbill turtle (Eretmochelys imbricata) from Pacific coast
of Costa Rica revealed the presence of a rich digenean fauna including Carettacola stunkardi (Spi-
rorchiidae), Enodiotrema reductum (Plagiorchiidae), Cricocephalus albus, Adenogaster serialis, Epi-
bathra crassa, Pleurogonius lobatus, P. trigonocephalus, P. linearis, and Pyelosomum posterorchis
(Pronocephalidae). All helminths except C. albus and P. lobatus represent new geographical records
for Costa Rica. Carettacola stunkardi is reported for first time in an Eastern Pacific hawksbill turtle
and its pathological changes are here described. Histologically, nodular lesions on the serosal sur-
face of intestine revealed a mixed infiltrate of heterophils, lymphocytes, and histiocytes within necrotic debris. Granulomas with spirorchiid eggs were observed
