Remarks

• Systematics: This species is similar to R. malloti, the type species, especially in the state of the trullae, in which they represent the derivative extreme in the genus. (Takagi, 2021)
• Structure: Adult female at full growth robust fusiform or broadly elliptical, with msth, mtth, and abd I–IV lobed laterally and with pygidium broadly roundish along free margin. Median trullae entirely produced at apex of pygidium, robust, appressed together along mesal margins, broadly rounded apically, roughly serrate on lateral margins. In addition to an abundance of the dorsal macroducts, the infrasegmental submarginal row of macroducts occurring on the fifth abdominal segment, the submedian and submarginal clusters of macroducts on the sixth segment, the closely appressed and entirely produced median trullae, and the absence of lateral trullae may make the recognition of the species easy and certain. (Takagi, 2021)
• Biology: Females and males occurring on twigs. Male tests standing on the cephalic end, crowding together to make thick masses around female tests. (Takagi, 2021)
• General Remarks: Detailed description and illustration in Takagi, 2021. Comment by Takagi: This species has abundant macroducts. However, in the examined specimens, not all of the macroducts occurring on the head and thorax could be clearly distinguished into dorsal and ventral ones. These macroducts are, therefore, drawn all on the dorsal surface in Fig. 14, and none of them on the ventral surface except for the drawing B, in which some macroducts occurring laterally to the gland spines of the metathorax are shown to be ventral. In reality, some macroducts occurring within the margin of the cephalothorax and laterally to the gland spines of the mesothorax also appear to be ventral.
