Systematics: Subfamily DIASPIDINAE Tribe DIASPIDINI Subtribe FIORINIINA (Normark, et al., 2019) Rutherfordia appears to be closely related to Pseudaulacaspis. A number of species which may or may not fall into Pseudaulacaspis have one or two of the characters of Rutherfordia, but none of them fulfill the full requirements. Rutherfordia is adopted only provisionally (Takagi et al., 1989).
Structure: Adult female body fusiform to broadly turbinate. L1 prominent, zygotic basally, tightly appressed or almost fused together throughout, or separated from each other except basally and with a pair of well-developed setae between. Lateral lobes rudimentary if present (Takagi et al., 1989). These species except one agree in the adult females in having two small but thick patch-like scleroses on each side of the pygidial margin, one on the sixth abdominal segment just laterally to the mesal marginal macroduct and the other on the seventh segment laterally to the marginal macroduct. The exceptional species has stalked scleroses arising at those positions. All these species have unusually elongated marginal gland spines forming tufts on a few or several abdominal segments.
