Diagnosis
ReferenceDiagnosis

Lamsdell 2021Cephalic border not sharply set off from convex genae and preglabellar field; alae small, semicircular; facial sutures marginal, or with parallel anterior and posterior sections running close to each other and directed anterolaterally from eye tubercles to margin; genal caeca radiating over cheek lobes and in some cases extending onto cephalic border. Hypostome subrectangular, length (sag.) equal to that of glabella. Thorax with 20 or more segments; axis narrow; long (tr.) pleurae curving back at outer part may be extended into spines, with deep pleural furrows and convex posterior bands (Fortey & Owens 1997).
