 Heterorhabdus 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).

 Heterorhabdus lobatus male: 1 - See key to species groups of Heterorhabdus: ''papilliger'' Group (p.90, 102). 2 - Medianterior tubercular process of forehead angular and not produced into a spiniform process. Basal inner lobe of left P5 rather poorly developed with angular distally (Fig.74-f). 3 - In right P5, medial projection of 2nd exopodal segment terminally expanded, with a large, rounded lobe (Fig.74-h). 4 - In medial projection of 2nd exopodal segment of right P5, distal lobe more or less rounded and similar in size to proximal lobe (Fig.74-k).

epi-mesopelagic.
After Park (2000, p.105) this species is similar in habitus to H. guineanensis and H. papilliger.
This species is closely related to H. papilliger. Confusions can exist between this species and H. papilliger.
