Scanning electron microscopy and intraspecific variation of <i>Chordodes festae</i> Camerano, 1897 and <i>C. peraccae</i> (Camerano, 1894) (Nematomorpha: Gordioidea)

| Sumario: | The nematomorph species <i>Chordodes festae</i> Camerano, 1897 and <i>C. peraccae</i> (Camerano, 1894) are redescribed by using scanning electron microscopy (SEM). C. festae has a cuticle with four different areolar types, the crown areoles being the most noticeable with long spiniform processes. The terminal end in the male specimen has two short lobe-like structures and a ventral groove. <i>C. peraccae</i> has three areolar types in which, as in C. festae, some areoles form groups surrounding the crown areoles. Intraspecific variations were found in body length and body colour in both species and, in <i>C. peraccae</i>, also in the cuticle. |
