Ticks were found on two bat guano deposits in the Big Room during the initial study. They were not found on the two major guano deposits (Lunch Spot and Maternity Roost), but about 10 meters west of the Maternity Roost site. Since he found only immatures of the species in the cave Welbourn suggested that they were brought into the cave by bats, but were probably not reproducing in the cave (Welbourn 1999). We do not have access to any tick specimens from the initial study, so we cannot make the comparison with the animals found during the recent study. Intuitively it seems reasonable that only one species is involved here, and since we had adult animals for identification, we know that C. yumatensis is currently present in the cave. However, without specimens from the initial study we can not preclude the presence of C. nr. hasei in the cave at the time. Welbourn (1999) mentions a record of C. hasei taken from M. velifer in the state of Sinaloa, Mexico. We know of no confirmed records of this neotropical species from the U.S. (BMOC).
