Amphids medium sized, rounded oval shaped, located posterior to head papillae, amphidial opening pocket-shaped (Fig.
Second stage larvae (11 to 17 dpi) possessed a smooth circular oral opening, with presumptive lateral amphids (Fig.
Since diacetyl is detected primarily by the AWA amphid neurons and benzaldehyde by the AWC neurons (7), use of these two volatile attractants allowed for the separation of these two chemosensory pathways and the assessment of their interactions with the thermosensory circuits.
Cephalic end rounded, bearing four distinct circumoral papillae and a pair of lateral amphids present.
Amphids about at middle of stoma, oval 2.5-3.0 um wide, one fourth of corresponding body width.
nigrescens female, one of the dendrites in each amphidial nerve bundle forms a multilamellar structure within the pigmented cup, beginning about 100 [micro]m posterior to the amphid (Figs.
The studied specimens can be differentiated from Camallanus hypophthalmichthys Dogel and Akhmerov, 1959 (Moravec et al., 2004) described in China by the absence of 3 small caudal processes on the mail tail tip, the highest measurements of body length in both sexes, the greater number of ridges and anal papillae pairs, the size ratio of spicules and by the absence of amphids and deirids as well.
The head was bluntly rounded and contained 4 externolabial papillae, 4 cephalic papillae, 2 amphids, and a buccal cavity (length 5 [micro]m, width 4.5 [micro]m) with a tiny cuticular ring.
