[Paramaritremopsis solielangi n. sp. and Microphallus kinsellai n. sp. (Digenea: Microphallidae) parasites of Charadrii (Aves) of Belize (Central America)].

The authors describe and illustrate two trematodes from Belize (Central America): Paramaritremopsis solielangi n. sp. from the small intestine of Arenaria interpres is characterised by a body length of 478 microm, two short and pre-acetabular caeca, part of the uterus in close association with the cirrus-sac and left caecum, vitelline glands in the shape of a horseshoe, a short pre-ovarian cirrus-sac containing a long, cylindrical, voluminous and unarmed cirrus (size when evaginated: 150 x 20-30 microm) and Microphallus kinsellai n. sp. from the caeca of Actitis macularia characterised by a body length of 370 microm and a phallus which is 30 microm in diameter and asymmetrical (basically a pad with a moderately developed accessory lobe) and a straight ejaculatory canal. Levinseniella carteretensis is another microphallid recovered from Arenaria interpres. The term of "phallus" is proposed to name the male copulatory organ which characterizes the Microphallinae.
