... (Cylloceriinae) was scored as having two because the additional insertion is bilateral rather than median. We were unable to score this character for Pseudorhyssa which, although possessing a reservoir, lacks venom glands ( Figure 11D), and in the case of the Collyriinae, there is a well-developed venom gland but no reservoir (Quicke 1997). We were unable to find a gland in the specimen of Euceros frigidus prepared ( Figure 9F), however, the second Euceros species examined had a very small gland inserting at the apex of the reservoir ( Figure 9E). ...
