Table 2 Somatic and sexual characters used for the morphometric analysis of Paracanthonchus gynodiporata sp. n. from the four studied populations along the northeastern coast of Brazil. Morphometry of the holotype (holo) and paratypes of Paracanthonchus gynodiporata sp. n. from Cupe-PE in the northeastern coast of Brazil

From: Low genetic but high morphological variation over more than 1000 km coastline refutes omnipresence of cryptic diversity in marine nematodes
