Fabriciidae Rioja, 1923

Overview of Fabriciidae species collected from Falkland Islands in this study

	Form of collar	Prostomial eyes +/-	Pseudospatulate notochaetae +/-	Pygidial eyes +/-
Fabricinuda sp. 1	reduced to a low ridge all around, (with lateral notches?)	prominent black eyes present	present in ch. 3-8	pair of small black eyes present
Fabricinuda sp. 2	reduced to a low ridge all around, entire (except middorsally), ventrally with a large square-shaped pad	absent or very faint	present in ch. 3-8	absent
Novafabricia? sp.	with well-developed lobe ventrally	absent	?	absent

EXAMPLES OF ANTERIOR PERISTOMIAL COLLARS IN FABRICIIDAE:

1. Collar reduced to a low ridge all around except for conical to elongated lobes on either side of dorsal midline, or incomplete middorsally Fabriciola, or complete middorsally Pseudofabriciola.         

Fabricinuda (from Fitzhugh 2002).   

2. Collar membranous all around as in:                                       

e.g. Fabriciola (from Fitzhugh, 1983).

3. Collar as a low ridge dorsally and laterally, as a well-developed lobe ventrally (all other genera) e.g.:

                      

Pseudoaugeneriella                                                                                 Raficiba
