Thirty species of nematodes recovered from Piciformes hosts
are reported. Procyrnea anterovulvata n. sp. from
Chelidoptera tenebrosa brasiliensis is described and
compared to P. colaptes and P. pileata. The
considered morphometric parameters are mainly related to the
ratio between length of the body/distance of the vulva to the
anterior end. It is approximately 1:0.5 in P. colaptes
and P. pileata compared to 1:0.1 in the new species.
The male of Synhimantus (Dispharynx) crassissima is
described for the first time. Thelazia ( Thelaziella)
spizaeti is revalidated and new records are reported for
some species.
