Remarks

• Systematics: Williamsrhizoecus coffeae differs from the other two species in the genus in having multilocular disc pores and lacking a circulus and any tritubular cerores on the venter. In addition, the distribution of the clavate setae is present only on the anal ring and the body setae are flagellate. In W. basikyi, clavate setae are present on both dorsal and ventral surfaces, and the antennae and legs, but the setae on the anal ring are flagellate.
• Structure: Body elongate oval. Osioles absent. Antenna 6-segmented; clavate setae present on entire dorsal surface and restricted to submarginal and marginal areas of venter, absent from antennae; multilocular disc pores present on venter and circulus absent.
• General Remarks: Detailed description, illustration and photographs in Caballero & Ramos-Portilla, 2018.
