A Figs. 19G, K, O, P, Q ; 20 T, Y, Z 2015 Novispathodus aff. Clinatus Orchard & Sweet ; Chen et al., p. 111, fig. 7, nr. 6 (only). Number of specimens .> 10. Description. Segminate P 1 element. 6–10 denticles present. Te cusp is terminal and distinctly conical and often more reclined than anterior denticles. Anteriorly, the denticles are almost as high as the cusp and decline gradually towards the anterior end. Te denticles are mostly fused and the cusp is conical or sometimes swollen at mid-height. Te lower margin is straight to slightly upturned in the posterior half. Basal cavity rounded at posterior margin and tapers towards the anterior end. Basal groove runs from the basal pit to the anterior end. Remarks . Similar to Nv . ex gr. pingdingshanensis in size and in its overall morphological outline, but differs by having a conical and terminal cusp. Te denticles are straight, upright to slightly reclined, not recurved as in Nv. pingdingshanensis . In Nv . abruptus , the posteriormost denticles show a gradual decline that is not observed here. One of the elements illustrated by Chen et al. (2015) as Nv . aff. clinatus seems to fall within the variation of this species although it has more inclined posterior denticles. Occurrence. In the late Smithian UAZ 7 in Qiakong, Lilong, Guangxi , South China (this study).
