Botryopera
sp. A
Plate 6,
Figs. 7A
–

.
Remarks.
This species is similar to
Botryopera amabie
n. sp.
(Pl. 7,
Figs. 1A
–
6
) except that the cephalis is proportionally shorter and narrower, compared to the thorax dimensions. On average, the cephalis height is ~33 microns, rather than the
43 micron
mean of
B. amabie
.
The shoulders on the thorax are also more distinct, and the thorax tapers more dramatically, causing the shape to be less cylindrical in outline. The overall size is smaller than in
B. amabie
n. sp.
