Figure 1From: The evolution of antennal courtship in diplazontine parasitoid wasps (Hymenoptera, Ichneumonidae, Diplazontinae)Variation in tyloid morphology in Diplazontinae. Shape of tyloids found in four species of diplazontine wasps. (A) and (C) Syrphoctonus tarsatorius, antennal segments 9 to 15 (A) and 10 (C), showing narrow, linear tyloids with abundant pores. Scale bars = 200 μm and 30 μm. (B) and (D) Enizemum ornatum, antennal segments 8 to 14 (B) and 10 (D), showing broad, linear tyloids with no pores. Scale bars = 200 μm and 50 μm. (E) and (G) Sussaba erigator, antennal segments 6 to 12 (E) and 8 (G), showing drop-shaped tyloids with pores. Scale bars = 200 μm and 50 μm. (F) and (G) Sussaba pulchella, antennal segments 6 to 14 (F) and 10 (G), showing oval, two-coloured tyloids with pores. Scale bars = 200 μm and 50 μm.Back to article page
