本文报道了三个新的盔形目双壳类：Divariscintilla acententaculata，D. luteocrinita和D. cordi cordiformis被描述为占据来自佛罗里达中东部的螳螂虾Lysiosquilla scabricauda的洞穴的寄生虫。形态学比较与所有其他已知成员的属，包括两个先前描述的物种从同一洞穴系统（D。yoyo，D. troglodytes）和模式种D. Maoria，来自新西兰。定义本属的关键特征（铰链形态，花状器官，“悬足”结构）进行了讨论，特别是关于他们的存在，在其他galeommatoidea属。类似交配行为的种内相互作用被指出并作为双壳类中少数可能的例子之一进行讨论。
Three new galeommatid bivalves, Divariscintilla octotentaculata, D. luteocrinita, and D. cordi formis, are described as commensals occupying the burrows of the mantis shrimp Lysiosquilla scabricauda from central eastern Florida. Morphological comparisons are made with all other known members of the genus, comprising two previously described species from the same burrow system (D. yoyo, D. troglodytes) and the type species, D. maoria, from New Zealand. Key characters defining this genus (hinge morphology, flower-like organs, "hanging foot" struc ture) are discussed, especially with regard to their presence in other galeommatoidean genera. lntraspecific interaction resembling mating behavior is noted and discussed as one of the few possible examples in the Bivalvia.
