Figures & Tables

Fig. 1

Labrys filiformis n. sp. (female). A, B: Neck (stoma ; pharynx) C, D: Anterior end E: Entire body; F: Lateral field at mid-body; G: Reproductive system; H, I: Tail.

Fig. 2

Interpretative drawing of lip region of Labrys filiformis n. sp. based on scanning electron microscopy (SEM) observations in frontal (A) and lateral (B) view.

Fig. 3

Labrys filiformis n. sp. (light microscopy, female). A, B: Pharyngeal region; C: Anterior end; D: Amphidial aperture E: Spermatheca filled with sperm; F: Lateral field at mid-body; G: Reproductive system; H: Tail tip. All scale bars =10 µm.

Fig. 4

Labrys filiformis n. sp. (scanning electron microscopy [SEM], female). A: Anterior region (arrow at the excretory pore); B–E: Lip region in right lateral, subdorsal, sublateral and frontal views, respectively; F: Posterior region (white arrow at the vulva, black arrow at the anus); G, H: Vulva in lateral and subventral views, respectively; I: Excretory pore (arrow); J: Anus.

Bayesian 50% majority rule consensus tree inferred from 64 sequences of 18S rDNA (GenBank accession number and species name) under the GTR+G+I model. Bayesian posterior probabilities and maximum likelihood bootstrap values are given for appropriate clades in the form of BPP/ML BS. The new species is in bold.

Fig. 6

Bayesian 50% majority rule consensus tree inferred from 66 sequences of 28S rDNA D2-D3 (GenBank accession number and species name) under the GTR+G+I model. Bayesian posterior probabilities and maximum likelihood bootstrap values are given for appropriate clades in the form of BPP/ML BS. The new species is in bold.
