Paramarimetropsis solielangi n.sp and Microphallus kinsellai n.sp (Digenea: Microphallidae), parasites of Charadrii (Aves) in Belize (South America)

The authors describe and illustrate two trematodes from Belize (Central Ame rica): Paramaritremopsis solielangi n. sp. from the small intestine of Aren aria interpres is characterised by a body length of 478 mu m, two short and pre-acetabular caeca, part of the uterus in close association with the cir rus-sac and left caecum, vitelline glands in the shape of a horseshoe, a sh ort pre-ovarian cirrus-sac containing a long, cylindrical, voluminous and u narmed cirrus (size when evaginated: 150x20-30 mu m) and Microphallus kinse llai n. sp. from the caeca of Actitis macularia characterised by a body len gth of 370 mu m and a phallus which is 30 mu m in diameter and asymmetrical (basically a pad with a moderately developed accessory lobe) and a straigh t ejaculatory canal. Levinseniella carteretensis is another microphallid re covered from Arenaria interpres. The term of "phallus" is proposed to name the male copulatory organ which characterizes the Microphallinae.
