Diagnosis
ReferenceDiagnosis
J. S. Hollingsworth 2007A fallotaspidid trilobite with a wide cephalon and outwardly directed genal spines. Genal spine angle is advanced to align (tr.) with L1. Anterior border is wide, about 25% of cephalic length and strongly convex dorsally. Glabella narrow, parallel-sided to slightly tapered.
Ocular lobes connected to LA in posterior twothirds by eye ridges as wide as, but less elevated than the ocular lobes. At LA, eye ridges form an angle of 65ยบ with the sagittal axis. Ocular lobes wide and elevated posteriorly. Interocular area about as wide (tr.) as extraocular area.
