REMARKS
Since the well-known name “pyloniids” is not any longer applicable to this group on account of its nomen dubium status, Larcospiroidea , a superfamily name, is used herein. The Larcospiroidea consist of the Dipylissidae , Larcospiridae , Palaeotetrapylidae , Pylodiscidae (Clade M3) and Zonariidae (Clade M4). As explained in the remarks for Phorticioidea , the presence of S1a-girdle in the sense of Zhang & Suzuki (2017) is the key distinguishing trait of the Larcospiroidea (see figs 5.1-5.4 in Zhang & Suzuki 2017 ). Differing from the G1 of Phorticioidea , the G1 of the Larcospiroidea is conjoined by both the microsphere (S1a) and the S1a-girlde. The appearance of the overlapped orientation of the microsphere (S1a) and S1a-girdle appears the same in Phorticioidea and Larcospiroidea (compare figs 5.2 with fig. 5.5 in Zhang & Suzuki 2017 ). Differing from its spherical outline in the Phorticioidea , the central part of the Larcospiroidea is elliptical, with two transparent apertures and an S1a-girdle shadow is present (the middle figure in fig. 5.2 in Zhang & Suzuki 2017 ).
