HOLOTYPE:  Vejovis viscainensis, holotype (male) (CAS, Type No. 10429): 3.2 km N Miller’s Landing, Baja California Norte, México, 21-VI-1968 (S. C. Williams, M. A. Cazier).

Original description:
Vejovis viscainensis Williams, 1970f: 410-413, fig. 9-10.

Subsequent Accounts:
Williams 1980:

"Diagnosis. - Adults to 50 mm long. Base color of body uniform pale whitish yellow with very faint dusky underlying pigmentation. Metasoma with ventrolateral keels finely crenulate on segments I-IV, ventromedian keels smooth on segments I and II, smooth to finely crenulate on III, finely crenulate on IV; segment I as long or slightly longer than wide, segment II longer than wide, segment V 2.7-2.9 times longer than wide. Pedipalp with very elongate fingers and very slender palm, ratio of movable-finger length to carapace length 1.0-1.1; ratio of movable-finger length to palm width 4.2-4.3; ratio of chela length to palm width 5.8-6.2; fingers not scalloped; palm with keels smooth to obsolete, supernumerary denticles 6 on fixed finger, 7 on movable finger, primary-row denticles subdivided into 5 subrows on fixed finger, 6 subrows on movable finger. Pectine teeth 16-17 in males, 14-15 in females. Similar to V. puritanus but differs as follows: ratio of movable-finger length to palm length 4.0 or greater; males with 15-16 pectine teeth (not 17-19); pedipalp palm distinctly narrower than brachium (not with palm approximating brachium in width or wider)."

Distribution: NORTH AMERICA. México (Baja California Norte, Baja California Sur: Vizcaino Desert).

Published Records:  Vejovis viscainensis Williams paratypes: 5M, 4F (CAS), same locality as holotype; 1F (CAS; allotype), 23 km S Guerrero Negro, 16-IV-1969 (S. C. Williams), Baja California Sur, México; additional specimens, several sites in Baja California Sur (San Angel, 13 mi W San Ignacio; 1 mi E Las Bombas, 2 mi E Las Bombas), México. Baja California Norte, Mexico: 4.8 km N Manuela. 22-VI-1968 (Williams, Cazier). Baja California Sur: 42 km S El Arco, 17-IV-1969 (Williams); 32 km S Santa Rosalia,19-IV-1969 (Williams); 10 km S Santa Rosalia, 19-IV-1969 (Williams); 13 km NW San Raymundo, 30-VI-1968 (Williams, Cazier).
