Differential diagnosis. The genus differs from representatives of Bimichaeliini  by the features listed under the tribal diagnosis. Superficially, Proteromichaelia  appears similar to species of Bimichaeliini  with a neotrichous prodorsum, but can be separated from these by the pattern of prodorsal setae: the accessory setae are inserted only on the in -area, posterior to the sensilla, i.e., unlike in the other bimichaeliine genera, there are no accessory setae on the soft parts of the prodorsal rim. Instead, two of the three pairs of setae on the rim flank a pair of lateral eyes, which is also unique to the genus ( Figs. 90, 91View FIGURES 90−100).

Description. Clumps of large lamellae inside roundish cells of large lamellae (=primary pattern), secondary pattern by fine ridges, accessory dorsal setae with 10 to 20 cilia each ( Figs. 92View FIGURES 90−100, 134A, BView FIGURE 134); naso narrowest at base, enlarging distally, holotrichous set of prodorsal setae (six pairs) recognizable but some accessory setae present posterior to setae in, anterior pair of sensilla (ve) branched, setae vi, sce, exp and a pair of finely ridged eyes on the anterior rim, crista sclerotized ( Figs. 90, 91View FIGURES 90−100); chelicerae straight, with a pair of setae dorsally ( Fig. 94View FIGURES 90−100); palps short and stout, palpal solenidion without a basal tubercle ( Fig. 95View FIGURES 90−100); two baculiform solenidia on tarsi I and II, one baculiform solenidion on each of tibiae I-IV (instead of 2), one baculiform solenidion on genu II and III ( Figs. 98–100View FIGURES 90−100; Uusitalo 2010: Appendix 3); weak neotrichy on larval dorsum, venter holotrichous ( Figs. 103, 104View FIGURES 101−104).

Etymology. The name of the tribe and genus is a latinized combination of the Greek word “protero”, meaning earlier or more ancient, and “Michael”, referring to the British acarologist Albert Davidson Michael (1836–1927). The name refers to the set of primitive characters listed in the diagnosis of the tribe.
