The oviscape is the elongate, tubular or conical, basal part of the ovipositor. It is formed from the fused tergite and sternite of segment 7. It bears a pair of spiracles laterally, and a pair of flangelike lobes basolaterally. Its length is measured ventrally along the midline. The mesonotum is the dorsal side of the thorax. It is measured in dorsal view along its midline, from the anterior margin of the scutum to the apex of the scutellum.
