Diagnosis. Adults to 55 mm long. Base color of body pale yellow, pedipalp fingers similar to palm in color, no contrasting pattern. Metasoma with ventrolateral keels smooth on segments I-IV, ventromedian keels smooth to obsolete on segments I-IV, segment I distinctly wider than long, segment II as long as wide or longer, segment III longer than wide, segment V 1.9-2.1 times longer than wide. Pedipalp with moderately long fingers, palm moderately slender, ratio of movable-finger length to carapace length 0.7-0.8, ratio of chela length to palm width 3.6-4.6, ratio of movable-finger length to palm width 2.2-2.7, supernumerary granules 6 on fixed finger, 7 on movable finger, primary row denticles subdivided into 6 subrows by 5 slightly enlarged denticles on fixed finger, subdivided into 7 subrows by 6 slightly enlarged denticles on movable finger, mature males with large open scallop between fingers when chela closed. Pectine teeth 18-21 in males, 16-17 in females; carapace with frontal margin set with 4 or more pairs of conspicuous erect hairs. Similar to Vaejovis diazi but differs as follows: carapace with frontal margin set with 4 or more pairs long setae (not 3 pairs setae).

Distribution: NORTH AMERICA. México (Baja California Sur: Cabo San Lucas north to San Antonio).

Published Records: Baja California Sur, Mexico: 10.9 km SE San Antonio, 24-VII-I968 (Williams, Bentzien); 0.8 km E San Bartolo. 24-VII-1968 (Williams, Bentzien): 0.5 km S Rancho Buena Vista, 6-V-1969 (Williams): Punta Pulmo. 2-VII-1973 (Williams, Blair); La Ribera, 10-11-1966 (Roth, AMNH); 27 km N Todos Santos, Hondo Arroyo, 4-II-1966 (Roth. AMNH): 18 km W Punta Palmilla, 9-V-1969( Williams): Cabo San Lucas, 19-VII-I968 (Williams, Cazier).

Notes: Williams (1980): "In the original description, the type-locality was stated to be Cape San Lucas with Xantus de Vesey as collector.  Numerous scorpions were subsequently taken in the Cabo San Lucas region to resolve the identity of V. eusthenura.  Seven species of scorpions were found in the Cabo San Lucas region.  Of these, three were in the genus Vaejovis, and only one of these agreed with Wood's original description of V. eusthenura.  The above diagnosis is based on presumed topotypes from Cabo San Lucas since there is little doubt that these represent the same population described by Wood as V. eusthenura."
