Phaneropsolus spinicirrus n. sp. (Digenea: Lecithodendriidae), a human parasite in Thailand.

Abstract

Phaneropsolus spinicirrus n. sp., collected in a postpraziquantel treatment stool of a 44-yr-old woman from Kalasin Province in northeastern Thailand, is described. It is the second species of the genus Phaneropsolus Looss, 1899, found to parasitize a human host. It differs from the first species, Phaneropsolus bonnei Lie, 1951, in the presence of a short spinose cirrus and the structure and distribution of tegumental spines. The new species is most similar to Phaneropsolus perodictici Goodman and Panesar, 1986, isolated from the potto, Perodicticus potto, in Uganda because digeneans of both species have numerous spines on the cirrus. However, the new species differs from P. perodictici in having more conspicuous spines, the genital pore at the posterior border of the oral sucker or lateral to the pharynx, a body and internal organs of larger size, conical spines on the tegument, an ovoid to bilobed ovary and a large V-shaped excretory bladder. Phaneropsolus spinicirrus is distinguishable from other previously reported Phaneropsolus by possessing a spinose cirrus.
