Remarks.

Notomastus aberans was described from South Africa and de León-González (1994) reported it for the western coast of the Baja California Peninsula. Examination of the Mexican material, found that this was Notomastus polyodon Gallardo, 1968 described from Vietnam. This was corroborated after the revision of the holotype of that species. The Mexican specimens as well as the type material of Notomastus polyodon have a mid-dorsal lobe between the thoracic notopodia on chaetiger 8 to 11 and the abdominal notopodia and neuropodia have expanded edges appearing as triangular lobes. Furthermore, methyl green staining patterns are similar in both specimens, with the prostomium and first three segments staining light green, segments 4 to 8 intensely green, segments 9 to 11 with a wide prechaetal dark green band moderately staining, abdominal segments, and two intensely staining lateral bands to the end of the fragment.
