Ovigerous male and late embryo of Nymphon floridanum. A Adult male bearing different postembryonic instars; lateral view; stereomicroscopic image. At first, the attaching instars are equipped with yellowish yolk reserves (arrowheads). In postlarval instar 3 (double arrow) the yolk has been exhausted. Note significant collapse and folding of the ethanol-preserved instar 3 specimen. B and C Pre-hatching embryo with cheliphores and anlagen of palps and leg pairs 1–3; SEM micrographs showing lateral (B) and ventrolateral (C) views. The embryonic cuticle is extensively folded. The small arrowhead points to fibrous secretions that project from the attachment gland spine’s distal tip. The stippled outline marks a remaining piece of the manually removed egg membrane. The asterisk labels a dirt particle. Abbreviations: ags – attachment gland spine; ch – cheliphore; l1-3 – leg pairs 1–3; pa – palp; pr – proboscis
