From various Texas caves, Ceuthophilus species B appears to share similarities with C. secretus and C. cunicularis.

From various caves of the Guadalupe Escarpment, C. carlsbadensis and C. longipes share similar cave adaptations with C. conicaudus (Pate 2001).

Primnoa resedaeformis Lamouroux 1812

For over 150 years Primnoa was the name used when referring to a genus of Eurasian grasshoppers or a deep water red tree coral. In 2003 two aspiring Orthopterists (i.e. Ito 2003, Mayer 2004) working in separate parts of the world, both realized the need for a nomenclatural change with regard to Primnoa (Orthoptera).
