Distribution:

Many groups of insects are associated with parasitic, phoretic, mutualistic and ammensal nematodes. However, the nematode associates of tenebrionid beetles have not been sufficiently examined except for those used as bait for entomopathogenic nematodes All field-collected tenebrionid-associated nematodes are the juveniles or eggs of spirurid and ascarid vertebrate parasites that apparently use the beetles as intermediate hosts.  In the case of Lenisaphelenchus ulomae,  the parasitic nematode uses the tenebrionid beetle as its final host.

The host insect, Uloma marseuli, is widely distributed in East Asia. It is univoltine and overwinters in dead trees so its habitat is sufficiently humid. The eggs of both nematode parasite and host beetle hatch and develop to adults in the same place, suggesting both parasites and phoretic associates can be transmitted vertically (Kanzaki and Hamaguchi, 2020.
