Original description:
Vaejovis intermedius Borelli, 1915: 6;

Subsequent Accounts

distribution: NORTH AMERICA. México (Chihuahua, Coahuila, Durango, Nuevo León), USA (Texas).

Published Records:  Vaejovis intermedius Borelli Paralectotypes: 2M, 3F (MIZT), same locality as lectotype.

notes: Hoffmann’s (1931) record of V. intermedius from the Sierra de Guadalupe north of MéxicoCity (repeated by Díaz Najera, 1975: 22 and Beutelspacher, 2000: 89, 139) is either referable to a different species or is a labeling error. The specimens could not be located for confirmation of their identity. Sissom (1991) suspected that they might be V. nigrescens, which closely resembles V. intermedius and occurs in parts of central México. However, E. González Santillán (pers. obs.) is aware of only V. granulatus in the Sierra de Guadalupe, but suspects V. mexicanus mexicanus is also there.
As pointed out earlier (Sissom, 1991b), Díaz Najera's (1975) record of V. intermedius from San Juan de los Lagos, Jalisco (repeated by Beutelspacher, 2000) is based on a misidentification of V. intrepidus cristimanus; his record for Ixmiquilpan, Hidalgo is probably based on a misidentification of V. nitidulus. New records from Distrito Federal and Jalisco reported by Beutelspacher (2000) are also in error; another record based on a specimen from Vizarrón, Querétaro is referable to V. nitidulus.
