Male epiproct.
Apical segment of upper limb ca. 287 μm long, bearing a pair of dorsolateral ear- like projections and a dense median patch of wave-like spikes (
Figs. 13-16
). 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
). Apical segment ca. 147 μm wide across ear- like projections, and narrowed to ca. 29 μm at apex (
Fig. 14
). 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.
Male tergal process.
Prominent raised structures on abdominal terga 7 and 8 (
Figs. 15, 17-18
). Process of tergum 7 thin in lateral aspect, forming a triangular projection in anterodorsal aspect, covered over much of surface with scale-like structures (
Figs. 17-18
). Process of tergum 8 thin in lateral aspect (
Fig. 15
) and tapered to a slightly concave dorsal surface in anterodorsal aspect; dorsum of process covered with a narrow strip of scale-like structures; width of process ca. 176 μm.
