Diaphanotheca is a generally thick, light colored, amorphous layer adjacently below the tectum which is the darker primary wall layer.  Kariotheca, which developed from Diaphanotheca has a honecomb-like alveolar structure, seen as narrow  pillars in cross section.  Upper and lower tectora can be thought of as veneers on the upper and lower sides.

Loeblich and Tappan 1988 <small>[1]</small> separates the Schubertellinae as the family [[Schubertellidae]] and the Schwagerininae as the family [[Schwageridinae]]; defines the Fusulinidae as having  a wall composed of tectum and upper and lower tectora or of tectum and diaphanotheca; a single tunnel and weak to massive chomata.  The Schubertellidae have varied coiling especially in the early stages and a variety of wall structures.  The Schagerinidae have a wall of tectum and alveolar kariotheca and strongly fluted septa.
