Figure 1:

Photomicrographs of cysts, vulva cones and second-stage juveniles (J2) of Cactodera torreyanae. A: Entire cyst; B-C: Vulva cones; D-E: Anterior end of J2s; F: Cyst anterior end (arrow showing anterior end of J2 with stylet sticking out); G-H: Tails of J2s; I: Lateral field with 4 incisures for J2.

Phylogenetic relationships within the genus Cactodera as inferred from Bayesian analysis using the D2-D3 of 28S rRNA gene sequences under the GTR + I + G model. Posterior probabilities are given for appropriate clades. New sequences obtained in the present study are indicated in bold.
