Travisia Johnston, 1840
Travisia sp. 1
Voucher. TOROA: station T4FB.
Diagnosis. Small, complete specimen; body inflated, compact (=”grub-shaped”), thickest at middle and tapering to both ends; 3 mm long and 1 mm for 17 chaetigers. Body whitish to pale yellow. Integument rugose; ventrally segments crowded; dorsally each segment with 3 rows of reticulated pattern, composed of rectangularish (much wider than long) cells. Prostomium sharply conical, much longer than wide; eyes absent. All chaetigers biramous; without obvious parapodia. First chaetiger with chaetal fascicles shifted dorsally; chaetal fascicles well separated in all chaetigers. Branchiae absent. Two achaetous, pre-anal segments. Anal cylinder abrupt after last parapodial segment, very small and short, composed terminally of 4-5 short, rounded lobes.
Remarks. This is a small, featureless specimen that does not appear to fit any known species in this genus as it is very small in size, possesses low number of segments and lacks characters such as branchiae, distinct parapodial lobe or obvious nephridiophores. The lack of branchiae align this species with abranchiate species previously assigned to genus Kesun Chamberlin, 1919, which has been synonymised with Travisia by Dauvin and Bellan (1994). Falkland Island specimen is here assigned to morphospecies Travisia sp. 1.
