Scanning electron micrographs of the cribellum and spinnerets in the spider N. albofasciata. a Cribellum (CB) is located at the upper region of the anterior spinnerets (AS). b, c On the anterior lateral spinneret, the major ampullate gland (Am) and the pyriform gland (Py) spigots were observed. d On the posterior median spinneret (MS) the minor ampullate gland and the aciniform gland (Ac) spigots were distributed. e On the posterior lateral spinnerets (PS), spigots of the aciniform glands are seen. Scale bars indicate 100 μm (a), 20 μm (b, e), 10 μm (d), and 5 μm (c), respectively
