TY - JOUR AU1 - Poinar, George O. AB - A new species of fossil mermithid, Cretacimermis aphidophilus sp. n. (Nematoda: Mermithidae), is described from the primitive extinct aphid, Caulinus burmitis (Hemiptera: Burmitaphididae), in mid-Cretaceous Myanmar amber. Aphid parasitism by mermithid nematodes is rare today with only two known cases involving root-feeding aphids. Based on the habits of the parasitised extant aphid hosts, it is likely that the fossil aphid was also a root parasite and encountered the infective stage mermithid in the soil. Such fossils provide rare glimpses of nematode-host associations from the distant past and provide minimum dates for the appearance of specific mermithid clades.
