Figure 3. Sting parts of Crabro scutellatus. (a) – lateral parts of tergite 9, dorsal view; (b) – lateral sclerite of tergite 9, medial view; (c) – furcula, lateral view; (d) – 2nd valvula, lateral view, scale bar; (e) – the 2nd ramus, fused with the rostral process of the 2nd valvifer, laterofrontal view; (f) – the 3rd valvula, lateral view; (g) – apical cone-shaped process of the 3rd valvula, laterodorsal view; (h) – the 1st valvula +1st ramus+1st valvifer+2ndramus+2nd valvifer; (i)–valvillus, medial view; (j) – the 1st and 2nd valvulae, lateral view. A-D – LM; E-J – SEM. Arrowheads indicate regions of interest. Scale bars: 200 µm in A and D; 100 µm – in B, F, H; 50 µm – in C; 20 µm – in E, G, I, J. l – lateral direction; p – posterior direction; v– ventral direction.
