Abstract
Summary: The reference of Isograptus manubriatus (T. S. Hall) to the genus Maeandrograptus Moberg by Skevington (1968) is argued to be invalid. A new genus, Pseudisograptus has been introduced to which the manubriate isograptids I. manubriatus, I. hastatus, and I. dumosus are referred.Keywords
