Espèce Heterorhabdus lobatus - Planche 8 de figures morphologiquesHeterorhabdus lobatus female:
1 - See key to species groups of Heterorhabdus: ''papilliger'' Group (p.90, 102).
2 - Midanterior tubercular process of forehead produced into a rounded process and not produced into a spiniform process. P5 without inner marginal seta on 1st endopodal segment.
3 - Laterally, genital prominence extending down to posterior end of somite (Fig.74-b).
4 - Laterally, genital prominence somewhat truncate, with a steep anterior wall making an angle of about 75° with longitudinal axis of somite (Fig.74-b).
