Stylochus franciscanus - note more eerebral eye pairs than S. exiguus and marginal eyes only 
about 1/3 to 1/2 way along the body (just to or slightly beyond eerebral tentaeles); tentaeular eyes 
within tentaeles; this speeies is mueh thieker than Stylochus exiguus. 
Stylochus insolitus - easy to ID by eolor pattern; brown spots and longitudinal bars in mid and 
posterior seetions and transverse bar aeross anterior region (tentaeles). 
Stylochus tripartitus - thin speeies, note thin line of eerebral eyes between tentaeles; tentaeular 
eyes within tentaeles. 
Cryptocelis occidentalis - eommon in the infaunal eommunity; note eerebral eyes in two, 
unstruetured longitudinal rows between tentaeles, reaehing anterior and posterior to tentaeles. 
Hylocelis californica - very thiek animal; see voueher sheet for dififerenee between Interplana and 
Hylocelis, the latter having more eyes. 
Interplana sandiegensis - nuehal tentaeles nipple-like; tentaeular eyes loosely seattered and 
extending only posteriorly from base of nuehal tentaeles; eerebral eyes start sparsely at base of 
tentaeles, extending forward into a broad group; shallow bays/harbors but also shallow off-shore. 
Hoploplana californica - ean be heavily pigmented (red to purple); dorsum with dense papillae, 
oeeasionally with surfaee papillae absent (removed via sieving); tentaeular eyes in ring at base of 
tentaeles, not within tentaeles; eerebral eyes medial and anterior to tentaeles. 
Hoploplana sp A - only speeimens seen are ivory white and with dense, elongate dorsal papillae; 
tentaeular eyes in ring at base of tentaeles, not within tentaeles; eerebral eyes in linear row 
between tentaeles. 
Parviplana hymani - no nuehal tentaeles; ean be without pigment and/or spotting or will have 
reddish-brown body eoloration with some spotting; eerebral and tentaeular eye elusters few in 
number, tentaeular eyes larger (previously referred to as P. californica by SCAMIT). 
Leptoplanidae sp A - two eerebral rows of three eyes (3 pairs). NOTE - voueher sheet shows set 
of spots posterior to eyes, not aetual eyes, but debris artifaet. 
Notocomplana acticola - eommon in the ISS (Introdueed Speeies Survey); reddish-brown 
dorsum, exeept where eerebral and tentaeular eyes are loeated; this area (eye loeation) is opaque, 
appears like headlights; tends to be a thiek speeies. 
Notocomplana rupicola - Van Veen grab speeies; four distinet, separate eerebral and tentaeular 
eye elusters; deeper water (>100 meters). 
Pleioplana inquieta - body beige to light tan, with distinetive brown spots eovering the dorsum; 
more prevalent in bays and harbors but rarely present offshore. 
Armatoplana reishi - not elongated; eerebral eyes starting anterior to tentaeles and extending 
posteriorly between tentaeles; pieture shows ruffled pharynx and ovaries. 
Emprosthopharynx gracilis (was as Stylochoplana) - “euneate” form (anteriorly broad, posteriorly 
narrowed); pharynx ruffled; tentaeular sets of eyes widely separated. 
Phaenoplana longipenis - tentaeular and eerebral eye elusters form a eontinuous band, tentaeular 
eyes mueh larger; body elongate, thin, opaque to light brown.
