Present study.

A. felis 

Supplementary observations

(measurements based on seven specimens). Body 890 (762-1,025; 7) long; greatest width 158 (107-200; 7). Pharynx 67-80 wide. MCO 81 (70-90; 7) long. Haptor 128 (105-145) wide. Onchium 39 (32-43; 5) long. Ventral anchor 40 (37-42; n=8) long; dorsal anchor 42 (38-45; 9). Ventral bar 61 (56-65; 4) long; dorsal bar 44 (38-49; 4) long. Hook pair 7, 46 (40-52; 5).


In A. felis  a simultaneous infection with N. felis  was found. Since all worms could not be identified, the data on infection rate relate to N. bravohollisae  and N. felis  . Neotetraonchus bravohollisae  was originally described on Galeichthys felis  (Linnaeus) (now A. felis  ), from Dauphin Island, Alabama coast, Gulf of Mexico ( Paperna 1977), and posteriorly reported on Hexanemathichthys assimilis  [now Ariopsis assimilis  ( Günther, 1864)] from Chetumal Bay, Yucatan, Peninsula on the border between Mexico and Belize ( Aguirre-Macedo et al. 2007). More recently, N. bravohollisae  was redescribed based on its type specimens and other specimens collected on A. felis  in the Gulf of Mexico off the Yucatan, Peninsula Gulf of Mexico (Telchac Puerto and Port of Celestun) ( Kritsky et al. 2009a). Measurements and the morphology of the sclerotized structures of the present specimens fit well with those redescribed by these latter authors.

Specimens deposited.

Seven reference specimens in the CNHE (10617).
