(previous page) SEM (a–d) and light microscopic (e–i) images of the ovipositor of Habrobracon hebetor a overview of the ovipositor (lateral aspect; visible pore-like structures are presumably artefacts of detached trichomes) c 1st valvifer exhibiting the interarticular ridge and the hook-shaped lobe of the 2nd valvifer. The 1st valvifer is continuous with the dorsal rami of the 1st valvula and is articulated with the 2nd valvifer and the female T9 via the intervalvifer articulation and the tergo-valvifer articulation, respectively d sensillar patch of the 2nd valvifer (made visible by partly removal of the 1st valvifer) b, f sensillar patch of the 2nd valvifer e overview of the 2nd valvifer and female T9. The arrow shows the dorsal hump of the T9 g tergo-valfiver articulation between the 1st valvifer and female T9 h detail image of e. The laterally placed bulbs of the most proximal part of the 2nd valvula are articulated with the paired 2nd valvifers via the basal articulation i sensilla in a row at the dorsal margin of the 2nd valvifer.
