| B. S. Lieberman 2001 | Same as for genus. [Parafrontal band long (exsag.) anterior of anterolateral margins of LA (L4), 50 percent length (sag.) of L0; length (sag.) of LA (L4) equal to length of L0 and L1; outer band of ocular lobe near lateral margin of LA (L4) expands prominently exsagittally; ocular lobes of constant dorso-ventral elevation between axial furrows and mid-point of ocular lobes, contact anterior and posterior parts of LA; ocular lobe between visual surfaces and LA equal to approximately 33 percent width (tr.) of glabella at L1; distal margins of L3 convex outward; S3 jaggedly convex; distal margins of L2 diverge anteriorly; width (tr.) of extraocular region opposite L1 equal to approximately 125 percent width of glabella at L1; genal spine angle developed opposite medial part of distal margin of L0; intergenal angle directed anteriorly at roughly 30 degree angle; anteromedial margin of third thoracic pleural segment parallels transverse line; third thoracic segment macropleural; anteromedial margin of third thoracic pleural furrow directed weakly posteriorly; thoracic pleural spines on segments 5–8 developed as short projections extending three segments back; thoracic pleural furrows extend roughly width of in- ner pleural region.] |
