Nerve ring 139-151, excretory pore 374-413 and deirids 262. Excretory pore posterior to distal end of esophagus, deirids on its posterior end of esophagus or slightly anterior to it. Tail elongate, 105-113 long, with pointed tip.

Remarks.

These were two very small and poorly developed cucullanid larvae and it was not possible to identify them to species. Perhaps, they represent new infections, or this fish acts as paratenic host. These are the first cucullanid nematodes reported from C. ignobilis and the family Carangidae in the Indo-Pacific Ocean.
