Comparative morphology of the musculature of the sting apparatus in Ampulex compressa (Hymenoptera, Ampulicidae) and Sceliphron destillatorium (Hymenoptera, Sphecidae)


	Second ramus-second valvula muscle (2r-2vv) interconnecting the second ramus and second valvula. A. Line drawing of 2r-2vv, not found during dissections, based on B. reconstructed volume of Sceliphron destillatorium. Lateral view, anterior to the right. 2r-2vv – second ramus-second valvula muscle.
