Remarks.
Dolichodorus heterocephalus
was described from specimens collected from fresh water at Silver Springs, Florida, and Douglas Lake, Michigan, by
Cobb (1914)
. It was reported from Massachusetts (
Paracer 1968
) and New
Jersey
(
Hutchinson
et al
. 1961
). It is also known from
South Africa
(
Heyns 1971
) and
Italy
(D'Errico
et al
. 1977).
Golden
et al
. (1986)
designated a
lectotype
of
D. heterocephalus
and presented detailed morphometric data from its
type
locality and several other populations including ones from Sanford and Gainesville, Florida, and East Wareham, Massachusetts, which revealed some differences in morphometrics among populations.
Perry (1953)
reported that
D. heterocephalus
caused severe stunting accompanied by depleted root systems of celery and corn in Florida. In the current study,
D. heterocephalus
was only found in a bermudagrass tee in Beaufort County, SC. The morphological features did not differ from the original and other populations (
Cobb 1914
;
Orton Williams 1974b
). The morphometrics of the identified population matched the
type
population in Gainesville, Florida (
Golden
et al
. 1986
), except for a slightly smaller range in body lengths for males and females, and a greater
a
value for females. This is the first record of
D. heterocephalus
from turfgrasses in SC.
