Remarks

• Systematics: Heteromargarodes was defined based on adult female morphology and originally included only H. americanus Jakubski, 1965. Unruh and Gullan (2007) later transferred Margarodes chukar (La Rivers, 1967) and Porphyrophora hiemalis (Cockerell, 1899) to the genus based on “(i) raised bare patches on the derm, (ii) long hairlike body setae, and (iii) sievelike multilocular pores” All species of Recent Heteromargarodes are distributed in North America. The adult males of H. americanus and H. ?chukar have been described (Hodgson and Foldi, 2006). At the time of the description H.?chukar was assigned to Margarodes, and based on comparison with Margarodes prieskaensis (Jakubski, 1965), the authors already doubted the assignment of this species to Margarodes, although they did not suggest a potential genus transfer. Additionally, it is possible that the specimen identified and described in Hodgson and Foldi (2006) is not H. chuckar. Therefore, Heteromargarodes hukamsinghi is assigned within this genus based on the description of the adult male of H. americanus. (Vea & Grimaldi, 2015) It differs from the male of H. americanus described in Hodgson and Foldi (2006) based on the following characters: leg setae spinose (vs. hairlike), large bristles on flagellar segments absent (vs. present), penial sheath longer.
