Remarks
- Systematics: Following Kozár & Konczné Benedicty (2007), this genus belongs to the subtribe Rhizoecina based on the presence of tritubular pores; the presence of clavate body setae distinguishes this genus from the others in the subtribe. However, the study of adult male morphology by Hodgson (2012) found little support for the subdivisions of Rhizoecini (now Rhizoecidae) proposed by Kozár & Konczné Benedicty. This casts some doubt on their decision to separate Ripersiellina from Rhizoecina, which was based on adult females having either bitubular or tritubular pores, respectively. The possession of blunt sensory setae on the penultimate antennal segment is not diagnostic for this genus, as originally described (Kozár & Konczné Benedicty 2007), as this feature is common throughout the family. The description of Williamsrhizoecus was updated by Schneider & LaPolla in 2020. The
genus now includes species with 5 or 6-segmented antennae (originally 5-segmented only), with or without circuli (originally described as present), with or without multilocular disc pores (originally described as absent), with anal ring cells oval to elongate (originally described as elongate), and with 6–18 anal ring setae (originally described as having 6 setae).
- Structure: Body elongate oval. Antennae each with 5 or 6 segments; with 1 blunt sensory seta situated on penultimate antennal segment. Legs well developed. Dorsum and venter with trilocular pores. Multilocular disc pores present or absent. Oral collar tubular ducts absent. Tritubular pores present on dorsum and venter. With flagellate and clavate or falcate setae present on body surface, anal ring, legs, and antennae in varying combinations. Anal ring with oval to elongate pores, some with spicules, and 6–18 flagellate or clavate setae. Dorsal ostioles entirely absent, or only weakly developed if present. Circuli present or absent (Schneider & LaPolla, 2020)
