Entelegyne spiders have a conserved pattern of two major
ampullate gland spigots (MaAmp) on the mesal margin of the anterior
lateral spinneret spinning field, and a larger field of piriform
gland spigots (Pi) occupying most of the remaining surface of the
spinning field (Fig. 4A–C; Griswold et al., 2005: 58; Ramirez, 2014).
