HOLOTYPE:  Vejovis (Paruroctonus) grandis Williams holotype (male), CAS (Type No. 10417), Oakies Landing, 27 mi (43 km) S Puertecitos, Baja California, México, 12-VI-1968, S. C. Williams, M. A. Cazier.

Original description: Vejovis (Paruroctonus) grandis Williams, 1970b: 277-281, fig. 1-2.

subsequent accounts:
Williams (1980):

"Diagnosis. Adults to 80 mm long; base color of carapace, mesosoma, metasoma, pedipalps, and walking legs uniform bright yellow; carapace with underlying intricate, dark color pattern; mesosomal terga with dark underlying markings, posterior terga with dark markings more faded and not as extensive; pedipalp fingers reddish brown in adults. Ventrolateral keels irregularly serrate to deeply crenulate; ventromedian keels irregularly crenulate on segments I—III , irregularly crenulate to serrate on IV; space between ventrolateral keels on segments I-IV densely covered with stout reddish bristles, these very conspicuous.
Similar to P. vachoni and P. mesaensis, but differs from P. mesaensis as follows: dark dorsal markings, presence of red pedipalp fingers. Differs from P. vachoni as follows: telson more elongate and less swollen, vesicle with hairs longer and less bristlelike in males; pedipalp chela without deep, conspicuous, double-dentate proximal scallop."

distribution: NORTH AMERICA. México (Baja California Norte - northeastern desert regions from Mexicali south to Punta Trinidad, and following islands: Mejia, Angel de la Guarda, Pond, and Estanque.).

Published Records:  Vejovis (Paruroctonus) grandis Williams Paratypes: 1F (CAS, Type No. 10417; allotype), same locality as holotype; 1,895 specimens from the type locality and 12 other locations on the eastern side of the Baja Peninsula, Baja California Norte, México.
Baja California Norte, Mexico: 8.0 km W Colonia Progreso, 8-VII-1969 (Williams, Lee): 6.4 km N Rio Hardy Fish Camp, I9-VII-1969 (Williams, Lee); 4.8 km N El Marmol, 27-111-1956 (Wood, SDMNH); Agua de Higuera. 21-11-1969 (Snelling. LACM); 19.6 km E San Borja, 24-XI-1961 (Parrish); Isla Mejia (E side). 16-IV-1962 (Campbell): Isla Angel de la Guarda, 25-VI-I96I (Soule, Parrish); Isla Estanque, 13—III— 1971 (Lee); Punta Trinidad, 20-111-1971 (Lee).

notes:  Williams (1980) noted that this species was found only along the eastern side of Baja California in rocky volcanic habitats where considerable soil had accumulated and that it forms local color races throughout its distribution, being dark on dark soils and lighter on light soils.
