Comments. The morphological characters observed in the two female specimens collected agree with the description of the genus Trichuris, i.e. anterior part of body being long, narrow, tapered and whip-like; posterior part of body being broad and handlelike with bacillary band located in anterior portion of body (e.g. Robles, 2011). These specimens show a nonprotrusive vulva, oval and flat eggs with bipolar plugs. More material should be collected to identify them at species level.

This is the first record of the genus Trichuris in E. russatus .
