Notes: This species was exhaustively described by Shelley (1997). Our SEMs show details not noted on the drawings in that paper. The filaments on the posterior side of the anterior gonopods are seen here (f, Fig. 254 ) to be finely serrate, and representing a continuation of previously undetected fimbriate lamellae that border a distinct channel (c, Fig. 254 ) leading up the posterior surface of the gonopod from a similar region at its base. This basal fimbriate area may partially conceal a pore (p?, Fig. 254 ) homologous to the large pores seen posterior on the anterior gonopods in many of the other conotylids illustrated in this paper. The posterior gonopods, as Shelley (1997) illustrated, bear coxites seemingly arising from a reduced coxa fused to the sternum (cxs, Fig. 253 ), and with a strong, setose anterior lobe (al, Fig. 253 ) that is tightly appresed to the coxite on the lateral side. As in species of Austrotyla , the posterior gonopod coxites are cupped anteriorly and more or less conceal the smaller anterior gonopods in situ.
