Characters
of the genus. Spear 40-45u long. Excretory
pore and 2 or 3 hypodermal pores visible on the
neck. A pair of hypodermal lateral pores present just posterior
to vulva, a conspicuous
feature from a
ventral view. Uteri forming elongate spermathecae. Anus
and caudal pores almost terminal. Males with 3 ventromedian supplements
arranged as
illustrated for T. proximus.
Habitat: A single collection from native turf near Milbank, South Dakota.
These specimens are slightly longer than those reported by Allen from
the Netherlands, Maryland and
Pennsylvania. They most closely resemble T. proximus
from which they are readily distinguished by
the shorter spear, 45u : 60u, large hypodermal
lateral pores just posterior to vulva, and terminal anus.
