Notes on morphological characteristics of 25 cyst nematodes and related Heteroderidae

摘要

Based on the study of type specimens and other reliably identified nematode material, data supplementing or correcting the original descriptions of 18 Heterodera species (including four species mostly considered as species inquirendae), two Meloidodera and two Globodera species and one species each of the genera Cactodera, Camelodera and Cryphodera are presented. The main focus is on morphological characters of second-stage juveniles.
