Cotvlea 
Charaeters: 
• frontal tentaeles present or absent 
• ventral sueker 
• diagnostie pigmentation patterns 
• if ruffled pharynx present, will be in anterior third of body (rather than posterior half as found 
in Aeotyleans) 
• if tubular pharynx present, will be in anterior third of body 
• frontal = marginal = nuehal tentaeles (all referenee the same strueture) 
Pseudoceros montereyensis - ruffled pharynx anteriorly; dark brown frontal tentaeles (Euryleptids 
similar but with reddish-orange frontal tentaeles); eerebral eye eluster in anterior 1/3 of body; 
marginal eyes along anterior margin to either side of median line; body white with blaekish- 
brown mid-dorsal stripe; outer margin white, with thin blaek line inside of white margin; small 
blaekish-brown spots seattered aeross dorsum. 
Pseudoceros mexicanus - ruffled pharynx anteriorly; eerebral eye eluster in anterior 1/3 of 
body; marginal eyes along anterior margin and along anterior of frontal tentaeles; very thin, laey 
margins; dorsum eolored brown with white spots. 
Acerotisa californica - tubular pharynx anteriorly; without frontal tentaeles; hard to see very 
small ventral sueker; white body is typieal, but ean be pigmented; one pair large eerebral eyes
