Remarks. Cyclocoelum mathuri Jain, 1984 was originally described from two specimens from Actitis hypoleucos collected in the Agra District of India; however, C. mathuri cannot be distinguished from Cyclocoelum mehrotrai Sinha & Sahay, 1975 and is synonymized herein with the latter. Cyclocoelum mehrotrai is larger than C. mathuri (38,000–38,200 compared to 21,800), and although C. mehrotrai has a somewhat smaller cirrus sac (600, 2% of body length compared to 700, 3%) and a shorter posttesticular space (542–767, 1–2% of body length compared to about 850, 4%), the similar percentages of these sizes relative to body length suggest that these differences are a product of growth (size). In addition to the similarities in the measurements, both species have a largely intercecal uterus, the posterior-most uterine loops do not invade the posttesticular space, both are from scolopacid birds from India, and both have a rudimentary oral sucker present—Sinha & Sahay (1975); Jain (1984).
