Abstract

The hypostome of Glyptambon Holloway, 1981, provides additional morphological evidence that this genus is more closely related to the Siluro-Devonian subfamily Dalmanitinae than to Ordovician “Mucronaspidinae.” New species of Glyptambon are G. amsdeni n. sp., from the Ludlow Brownsport Formation in west-central Tennessee, and G. gassi n. sp., from late Wenlock strata of the Racine Formation in Illinois.
