saw (lancet or first valvula) dissected from female - with hair bands and 16 teeth, each bearing smaller denticulations (serrulae). different number of teeth to T. australis and different to T. nitidus in possessing serrulae

different number of teeth to T. australis and different to T. nitidus in possessing serrulae

enlarged view of end of saw (lancet or first valvula) showing teeth 1-6, each with 3 small serrulae (denticulations) Malagon-Aldana et al (2021) state that in the Trichorhachus sp. ovipositor examined (Fig. 27A,B) serrulae were absent.
