Notes on asteropygids

Many revisions have been made to this family in the past few years- For example: Most of the Moroccan trilobites referred to Metacanthina are now known as Philipsmithiana hyfinkeli or P- burtandmimae- Most Greenops boothi are now either Greenops grabaui, G- barberi, or G- widderensis- Most Neometacanthus calliteles are now various species of Bellacartwrightia, mainly B- jennyae, B- whiteleyi, and B- calderonae- These revisions are due mainly to a recent analysis done by Lieberman and Kloc, 1997- They eliminated most subgenera and erected 11 new genera- Although it stands for now, not all of their assignments are accepted-

But their work on North American species was quite good- Greenops boothi was restricted to specimens from the type locality in Pennsylvania, thus changing all other G- boothi to new species- The genus Neometacanthus was restricted to species resembling the type N- stellifer, so all North American species (calliteles) became new species of Bellacartwrightia-

Currently, most of the Moroccan species are under study by Brett (me) and Chatterton- Most can be assigned to Neometacanthus, Comura, Philonyx, Kayserops, Asteropyge, Heliopyge, Philipsmithiana, Hollardops, Rhenops, Psychopyge, Treveropyge, and maybe Metacanthina, among a few other possibilities-
