Median spike patch ca. 230 μm long and divided along entire length by narrow groove, spikes absent on ear-like projections and basal dorsolateral bulges ( Fig. 14 View Figs ). Apical segment ca. 147 μm wide across ear- like projections, and narrowed to ca. 29 μm at apex ( Fig. 14 View Figs ). Basal segment of upper limb ca. 280 μm long and ca. 100 μm wide for most of length; setation and dorsal longitudinal groove absent from basal segment. Lower limb ca. 200 μm wide proximal to apical spoon.
