SEM images of Venturia canescens. a The posterior part of the metasoma (lateral view) with the exhibited ovipositor that consists of the female T9, two pairs of valvifers and three pairs of valvulae. Because of the storage in ethanol and the drying procedure, the 3rd valvulae are coiled and do not embrace the terebra (formed by the interlocked 1st and 2nd valvulae) as in living animals (left is anterior). b Habitus image of V. canescens (lateral aspect). c–e Ovipositor excised from the genital chamber (left is anterior; c, lateral view; d, dorsolateral view; e, ventral view), so that the articulations of the 1st valvifer and the female T9 (tergo-valvifer articulation) and of the 1st valvifer with the 2nd valvifer (intervalvifer articulation) become visible. The dorsal rami of the 1st valvulae are continuous with the 1st valvifers. The fat arrows represent the direction of view of the other SEM images. f–g Detailed images of the tergo-valvifer and the intervalvifer articulation (lateral view, left is anterior) and the sensillar patch of the 2nd valvifer (in g). Abbreviations: 1vf, 1st valvifer; 1vv, 1st valvula; 2vf, 2nd valvifer; 2vv, 2nd valvula; 3vv, 3rd valvula; dr1, Dorsal ramus of the 1st valvula; iar, Interarticular ridge of the 1st valvifer; iva, Intervalvifer articulation; sp, Sensillar patch of the 2nd valvifer; T6, 6th abdimonal tergum; T7, 7th abdominal tergum; T8, 8th abdominal tergum; T9, Female T9; T10, 10th abdominal tergum; tva, Tergo-valvifer articulation
