One half, the hypotheca, is slightly smaller than the other half, the epitheca.
3.
The body is laterally compressed with a small, cap-like epitheca and a much larger hypotheca.
4.
Each daughter receives one of the parent cell's thecae, which becomes that cell's epitheca.
5.
:* Two-spotted Dragonfly " Epitheca bimaculata " was reported from Leicestershire in 2002 see Parr ( 2003 ).

As the diatom prepares to separate it undergoes several processes in order to start the production of either a new hypotheca or new epitheca.

9.
The dinoflagellate is separated into an upper portion called the epitheca ( C ) where the apical horn resides ( E ) and a lower portion called the hypotheca ( D ).
10.
This overlapping region is reinforced with silica girdle bands, and constitutes a natural " expansion joint . " The larger theca is usually thought of as " upper, " and is thus termed the epitheca.
