on the right side are preserved, as are the thorax and head. Spine 
bases are present on the bulbous region of the prothorax, although 
the spines themselves have broken off (see fig. 15). 
Synonymies 
S. lerichei. Holotype. IP 23. Specimen examined. Obverse half. 
S. agnusi. Holotype. IP 19/21. Specimen examined. Obverse and 
reverse halves. 
I am synonymizing these species with G. fischeri as there are no 
obvious specific level differences by which they may be recognized. 
The specimen of 5". lerichei is a well-preserved, dorsal compres- 
sion of almost the entire insect. Because the wings are separated, it is 
possible to interpret the venation of both fore and hind wings, and 
especially that of the fore wing. The venation, the prothorax (includ- 
ing spine bases) and the size of this insect are perfectly compatible 
with G.fisheri. 
The specimen of S. agnusi is a single fore wing, superbly pre- 
served. Although the apex of the wing is missing, the basal area.
