HOLOTYPE:  Vaejovis pattersoni Williams and Haradon. Holotype: M (CAS, Type No. 12250), vicinity of La Laguna (elev. 1,707 m). Sierra de La Laguna, Baja California Sur, Mexico, 1-3-VIII-1974, R. M. Haradon, V. F. Lee, W. E Savary.

Original description:
Vaejovis pattersoni Williams and Haradon in Williams, 1980: 54, 65-66, fig. 56F, 69, 75 :

Diagnosis.  - Prominent dorsal markings giving striped appearance. Pectine teeth 11-15 in males, 11-12 in females; females with proximal pectinal tooth distinctly smaller than other teeth in series; fourth and fifth enlarged denticles of primary dentate row retrolaterally offset on both pedipalp fingers; with distinct sharply pointed subaculear tooth on telson (Fig. 56F).
Description of Holotype. Male. Base color light yellow to yellow-orange; extensive dark fuscous markings on all body parts and appendages; dorsal mesosoma with two submedial and two lateral series of dark blotches giving appearance of stripes. Carapace surface lightly granular; anterior margin straight; median ocular tubercle set well forward of center of carapace. Terga lightly granular. Entire metasomal surface finely granular; dorsal and dorsolateral keels strongly crenulate to serrate; ventrolateral keels crenulate to serrate; ventromedian keels lightly granular on segment I, granular on segments IIV. Telson conspicuously smaller and narrower than metasomal segment V; ventral surface lightly tubercular, eight pairs of ventral and ventrolateral setae; distinct, well-developed subaculear tooth. Pedipalp palm surface smooth, keels obsolete; fingers scalloped proximally, form small gap when closed; 6 (fixed finger) and 7 (movable finger) large supernumerary granules, set well away from primary row; primary row denticles subdivided by 5 enlarged denticles on each finger, fourth and fifth enlarged denticles offset along retrolateral margin of each row; primary-row denticles do not extend to articulating margin.

distribution: NORTH AMERICA. México (Baja California Sur - Sierra de La Laguna).

Published Records:  Vaejovis pattersoni Williams, allotype and 24 topoparatypes: CAS ; from the vicinity of La Laguna (elev. 1,707 m). Sierra de La Laguna, Baja California Sur, Mexico, 1-3-VIII-1974, R. M. Haradon, V. F. Lee, W. E Savary.

notes:Sissom (2006): Williams (1980) placed this species in the eusthenura group.  Examination of a topoparatype revealed that it is closely related to members of the mexicanus group (e.g., V. granulatus Pocock) from mainland México (W. D. Sissom, pers. obs.). Williams and Haradon in Williams, (1980): "Variation within Paratypes.- Carapace length of males ranged 2.8-3.5 mm, females 2.9-3.7 mm. Pectine teeth 11-15 in males, 11-12 in females.", "Named after Donald Patterson, who encouraged and supported biological exploration of Baja California", "Most specimens were found under the bark of dead trees, although several were found under rocks".
