Fig. 5From: Morphological and molecular characterisation of Helicotylenchus zengchengensis n. sp. (Nematoda: Hoplolaimidae) from China, with a review on Helicotylenchus species in ChinaPhylogenetic relationships of Helicotylenchus zengchengensis n. sp. with the species of the genus Helicotylenchus. The phylogenetic tree was constructed by Bayesian analysis using 18S rRNA partial sequences, with the optimal model GTR + I + G under AIC standard. Posterior probability values exceeding 50% are given on appropriate cladesBack to article page
