This chapter describes the genus Paraheterohabdus. It reports that the taxon was erected by Brodsky (1950) as a subgenus with Heterorhabdus robustus Farran 1908 as a type species. It notes that Brodsky originally characterized Paraheterorhabdus as having a stocky body, massive legs, and short distal spines on the exopods of the male P5. It further notes that not all the species subsequently referred to by Heptner (1972b) as Paraheterorhabdus share such characters. It observes that Paraheterorhabdus vipera (Giesbrecht 1889) and P. medianus (Park 1970), for example, have an elongate body and slender legs, as in Heterorhabdus spinifrons (Claus 1863), the type species of the genus Heterorhabdus. It notes however, that Pareheterorhabdus is a valid taxon clearly distinguishable from all the other genera of the family Heterorhabdidae in morphological details mainly of Mx2 and Mxp.
