Four species of leeches were found in the Apolobamba Range of the Bolivian Andes. Collections were made from 4100 m down to 2820 m—among the highest collecting localities ever for leeches. There were three new species in the genus Helobdella including Helobdella ringueleti, Helobdella nununununojensis and Helobdella sorojchi as well as one representative of Cylicobdella coccinea One of the new species exhibited an attitude of parental care unique among glossiphoniids in that the brood was enclosed within two halves of the folded parent. None of these species is known to be sanguivorous.
