then reported as H. chitwoodi, was considered
as being as common as dagger nematode along north and central coastal vineyards of
California by Chang and Raski (1972). However, Pinochet and Raski (1975) considered this a misidentification and described the species on
grapevines in California as H. californianus.
Chang and Raski
(1972) reported that their "H. chitwoodi", from the type
host and locality of H. californianus, reproduced on grape, Vitis
vinifera 'Thompson Seedless', Vitis rupestris Scheele, 1848, and
grapevine hybrid 1613 (Solonis Othello). It did not reproduce on Camellia
japonica L., Wisteria or Cycas, leading to the conclusion that it was a biotype
different from typical H. chitwoodi.
A population of 10 females from
St. Helena, California, reported as H. mangiferae Siddiqi, 1961 by
Dasgupta et al. (1969) should be correctly classified as H. californianus.
