Holotype NHMW 2010/0036/0012 (NMMW coll.; ex. 
BL coll.), length 15.2 mm. lower shell bed, 1 km 
Southwest of Casa Cantaure, about 10 km west of 
Pueblo Nuevo, Paraguanâ Peninsula, Falcôn State, 
Venezuela. 
Discussion. Several Neogene Caribbean forms hâve 
been described. Pustularia mejasensis Schilder, 1939 
from Trinidad is represented by a single internai 
mould. However, because it is impossible to 
détermine what taxon this represents it should be 
considered nomen dubiurn. Pustularia americana 
Schilder, 1939 from the early Miocene of Cuba has a 
more solid shell, with less produced, extremities, 
wider siphonal channel, fewer columellar and labral 
teeth, which on the columellar side to not extend onto 
the ventrum and pustules on the dorsum adjacent to 
the labral marginal callus, and is better placed in the 
genus Erosaria. Propustularia caribaea (Schilder, 
1939) (holotype; Figs 151-154) from the early Middle 
Miocene Grand Bay Formation of Carriacou is 
extremely similar to P. longidentata [shell formula 
13.5 (64 - 50) 28: 23], but no bridge is developed 
between the anterior columellar teeth.

Type Iocality. lower shell bed, 1 km Southwest of 
Casa Cantaure, about 10 km west of Pueblo Nuevo, 
Falcôn State, Venezuela (=locality GS12PGNA of 
Gibson-Smith & Gibson-Smith, 1979). 
Type stratum. Cantaure Formation (early Miocene: 
Burdigalian). 
Description. Shell small for genus, solid, globular, 
weakly swollen posteriorly, spire involute, covered by 
adapical callus, extremities weakly projecting; sides 
rounded, nioderately callused, lip marginal callus 
sharply delimited and slightly thickened; ventrum 
flattened, weakly convex in profile; aperture narrow, 
edges parai lel, conspicuously curved to the left in the 
posterior third; siphonal canal moderately long, 
externally barely margined; exhalant channel 
moderately produced, strongly bent adaxially, 
externally barely margined; terminal ridge well- 
developed, tooth-like at its inner extremity; fossula 
narrow, weakly delimited from the rest of the 
columella, labral teeth extend across the fossula as 
elevated ridges and form teeth again at the inner edge 
of the fossula; 19-20 short columellar teeth, not 
extending past the angulation onto the ventrum; 20-22 
labral teeth extending less than half of the labral 
width. No dorsal sulcus, pustules or pitting présent. 
Colour pattern not preserved, under UV light 
suggestion large irregular spots on the posterior 
portion of the dorsum, the spots much wider than the 
distance between them. 
Etymology. named for the long teeth, seen especially Shell Formula. 17.0 (67.1 - 51.8) 25: 22 
in the holotype.
