Distribution:

Rather rare genus that has been reported in Africa, Asia, Europe and North America (Alvarez-Ortega et al, 2021).

Feeding:

 Xiphinemella species have been reported associated with forest trees and herbaceous plants such as cowpea (Vigna unguiculata (L.) Walp.), rice (Oryza sativa L.) and others (De Bruin and Heyns, 1991). However, there are no reports on the feeding habits of these species. So far, the species X. esseri has been found only in Florida, where it is often associated with oak trees such as live oak and Spanish oak or Southern red oak (Quercus falcata Michx.). Many longidorids such as Longidorus longicaudatus (Siddiqi, 1962), species of Xiphinema americanum group and Xiphinema setariae (Luc, 1958) feed on oak roots and are sometimes associated with X. esseri. It is possible that  X. esseri may have plant parasitic habits as suggested by Chitwood (1957) but parasitism of this and other species of the genus has not been scientifically demonstrated. (Alvarez-Ortega et al., 2021)
