Both new species belong to a group of species characterized by the presence of a bipartite basal esophageal bulb with striated or unstriated valve plates. H. shahinae n. sp. is characterized by its comparatively shorter body length (0.4\u20130.44 mm); annulated cuticle; amphidial fovea at 6\u20139 \u00b5m from the anterior end; bipartite basal bulb with unstriated valve plates; reproductive system mono-prodelphic with reflexed ovary, presence of post uterine sac and vulva at 52\u201357% of body length and tail short conoid, straight, 1.5\u20131.8 times anal body width long. H. sandspitensis n. sp. is characterized by more than 1 mm body length (1.0\u20131.2 mm); annulated cuticle; amphidial fovea at 8\u201312 \u00b5m from the anterior end; bipartite basal bulb with striated valve plates; didelphic reproductive system, with the vulva at 40\u201347% of body length and tail elongated, conoid, 1.4\u20132.2 times anal body width long.
