Georgiev, Eva Murai*, and Robert L. Rauscht Instituteof Ecology,Bulgarian Academy of Sciences, 2 GagarinStreet, 1113 Sofia, Bulgaria ABSTRACT: Burhinotaeniacolombiana n. sp. (Dilepididae)is describedfrom the small intestine of the double-stripedstone curlewBurhinus bistriatus (Burhinidae) captured at Carimagua,Colombia. The new speciesis distinguishedfrom the most similar Burhinotaeniadelachauxi (Baer, 1925), a parasiteof the Old World Burhinusspp., by the longercirrus-sac (375-590, avg. 514 Aimvs. 322-393, avg. 354 Mm)and longerrostellar hooks (412-451, avg. 440 ,umvs. 358-367, avg. 364 Am).The validity of the genus BurhinotaeniaSpasskii and Spasskaya,1965 and its genericdiagnosis as proposedby Bona (1994) are confirmed.This is the first recordof a species of Burhinotaeniain the New World. The double-striped stone curlew Burhinus bistriatus (Wagler) DESCRIPTION occurs in Central America and northern South America, from Burhinotaeniacolombiana n. sp. southern Mexico to northern Colombia and northern Brazil (Figs.1-15) (Howard and Moore, 1980).
