Figure 5. Camera lucida drawings of half transverse (frontal or cross) 10 μm sections of the prosoma of a fifth instar Phidippus clarus (1), and a sixth instar P. johnsoni Peckham & Peckham 1883 (2). In each drawing the midline is at the right. 1, Section through the posterior lateral eye (PLE). The short optic nerve of each lateral eye (ALE and PLE) has its own folded first neuropile (PL1 for the PLE). interneurons associated with this neuropile are associated with tracts leading to both the glomerlar synapses (or glomeruli) of the corpora pedunculata, and to a lateral eye neuropile. 2, Section through the sucking stomach. The CNS is separated from the sucking stomach by the endosternite, an internal skeletal element comprised of a cartilage-like material. This view emphasizes the powerful musculature that fills much of the prosoma. Many of these striated muscles are attached to the endosternite. After Hill (1975, 2006).
