Type Species. Graemeloweus iviei (Gertsch et Soleglad, 1972) , comb. nov. [= Vejovis iviei Gertsch et Soleglad, 1972 ], designated here.

Composition. This genus contains three species: G. iviei , comb. nov. [= Vejovis iviei Gertsch et Soleglad, 1972 ] (type species); G. glimmei , comb. nov. [= Pseudouroctonus glimmei ( Hjelle, 1972) ]; and G. maidu , comb. nov. [= Pseudouroctonus maidu ( Savary et Bryson, 2016) ].

Distribution. Found in northern California, USA (Butte, El Dorado, Lake, Marin, Mendocino, Napa, Nevada, Placer, Plumas, Shasta, Sierra, Sonoma, Stanislaus, Tehama, Trinity, and Yuba Counties.). See map in Figure 11.

Diagnosis. Orthobothriotaxic. Hemispermatophore median area equipped with a non-bifurcated primary lamellar hook and a secondary lamellar hook; mating plug is complex, possesses a two-part base, and a large asymmetric smooth edged barb. Chelal palm planes formed by carinae D1 | D3 | D4 and V1 | V2 | V3 are not subparallel, due to a well developed ventromedian (V2) carina. Telson vesicle lacks ventral ridges at the aculeus juncture, subaculear setal pair located on vesicle/aculeus juncture, and vesicular linear patch not presence on the dorsal surface. Cheliceral movable and fixed fingers lack dentition and/or protuberances on their ventral surfaces. Ventral surface of leg tarsus with 1–2 distal spinule pairs. See Table 1 for measurements of these species.

Etymology. This genus (masculine in gender) is named in honor of our colleague and friend Graeme Lowe (Philadelphia, Pennsylvania, USA) who has made significant contributions to scorpion systematics.
