* Vogtia glabra Bigelow is not included in this comparison because it has rounded nectophores. 
The nectophores of V. kuruae n. sp. present 
an outline like a three-pointed star. Three 
isosceles triangles are arranged surrounding the 
nectosac in such a way that the imaginary bases 
or smallest side of the triangles circumscribe the 
nectosac (Figs. 1 and 2). These nectophores 
thus display the most exaggerated angular shape 
of all the previously described species, where the 
three-pointed shape is already incipient. In this 
species both edges and facets are completely 
smooth, without protuberances, spines, or serra- 
tions. 
On the dorsal part of the nectophores appears 
the nectosac, a shallow cavity outlined as a quite
