Nephila clavipes and maculata

The Nephila species (Figs. 5-9) have a very much stronger chelicerai m.antero-medialis verticalis than Azilia and thus resemble the Araneidae earlier dissected by me. N.clavipes has a cleft suspensor IV,. N.maculata a single one; this feature is apparently of little taxonomic value.

The anterior tergo-pedipalpal muscle [pa) is double-fanned in N. clavipes , but triple-fanned in.AT. maculata . The m. tergo-coxalis anterior profundus (c,, "anterior rotator") of the first leg arises in JV. clavipes as two broad portions; in N.maculata one of the portions is very narrow. None of the Nephila species has caecal pouches protruding between the tergo-coxal muscles. In JV clavipes the dorsal pouch is short. In JV. maculala it extends to the base of the chelicerae and sends a very narrow tube into them, a feature reminiscent of the Tetragnathidae . In this species the poison gland is short, while in JV. clavipes it extends to the dorsal apodeme. I have previously drawn attention to the apparent competition for space between the poison glands and the dorsal caecum.
