Remarks. As noted above, members of the subgenus Paraspidosiphon  have a longitudinal muscle layer separated into bands. Aspidosiphon fischeri  has pale hooks with a triangular base and both unidentate and bidentate compressed hooks on the inrtovert. The morphologically similar A. parvulus Gerould, 1913  has an anal shield with a diffuse border and nephridea greater than half the trunk length.

Distribution. Aspidospiphon (Paraspidosiphon) fischeri  is common in shallow coral rock and has been collected in the Caribbean from Cuba to Brazil. It has also been recorded from several sites in the eastern Pacific Ocean ( Cutler, 1994). Rice (1975) encountered this species at Margarita Island, Cubagua Island, and Los Totumos in Venezuela and Piscadera Baai and Spaacsche Water in Curaçao in calcareous rock and Porites  rubble.
