Figure 6. Ontogenetic dimorphism in Gagrellinae. Scanning electron micrographs of pedipalp patella and tibia. A, B, Metagagrella cf. minax: A, juvenile with a large patellar and a small tibial apophysis and plumose setae; B, adult female with reduced patellar apophysis and lacking tibial apophysis, glandular setae lacking, strong denticles present. C, D, Gagrella cf. disticta: C, juvenile, with plumose setae (marked with circles); D, adult female, with denticles. pa, patella; ti, tibia. Scale bars = 200 µm.
