Ethmorhabdus camaratus Bukry, 1969
Species of Ralphsalomonia are constructed of cretarhabdid pelaga surrounding a large central area spanned by a diagonal cross that supports a distal process. The inter-cross area is occupied by numerous pentagonal pores arranged in one or more complete concentric cycles. The number of pores in the outer cycle is typically 10-20.
Optical properties consistent with those of Ralphsalomonia.
