type(s):  Vejovis minimus Kraepelin 1911 -  Lectotype (designated by Gertsch & Soleglad, 1972: 600): F (ZMH), San Pedro, Los Angeles County, California, USA.

Original Description:

subsequent accounts:
Gertsch & Soleglad (1972):

"Small, granulated species with thick cauda about three times as long as carapace; frontal emargination shallow; median eyes situated in front of middle of carapace about one-third of distance back; lower margin of movable finger of chelicera smooth; segments I-III of cauda much broader than long, segment IV as broad as long, all about equal in width instead of segments III-IV being much broader in baueri; all keels on cauda granulated."

Williams (1980):

"Diagnosis. - Adults to 30 mm long. Metasoma short, stout, segments I through III distinctly wider than long, segment IV with length approximating width; segment V 1.3-1.4 times longer than wide; ventromedian and ventrolateral keels well developed, crenular. Pedipalp with short fingers, palms swollen; ratio of movable finger length to carapace length 0.8-0.9; ratio of chela length to palm width 2.3-2.4; ratio of movable-finger length to palm width 1.4-1.5; supernumerary granules 6 on fixed finger, 6 or 7 on movable finger. Pectine teeth 10-11 in males, 9-10 in females.
Similar to V. rufulus and V. baueri but differs from V. rufulus as follows: metasomal segment III wider than long (not as wide as long or longer); metasomal segment IV as wide as long (not distinctly longer than wide). Differs from V. baueri as follows: pedipalp fingers not terminating distally in conspicuous elongate, toothlike denticle; fixed pedipalp finger with terminal denticle length less than 34 depth of finger at first supernumerary granule; metasomal segment V not wider than segment III."

distribution: NORTH AMERICA. USA (California: Los Angeles County).

Published Records:  Paralectotypes: 1M, 1F (ZMH), same locality as lectotype.

notes: Gertsch & Soleglad (1972): Kraepelin (1911) based the name minimus on three examples of a small scorpion from San Pedro, California, and compared it with what were then the only presumed relatives, Vejovis carolinus of the southeastern United States and Vejovis pusillus of Mexico. The structure of minimus seems to ally it more closely with Vejovis baueri Gertsch (1958, p. 6) and various undescribed species of Baja California, and also to species of the wupatkiensis complex of the southwestern United States and adjacent Mexico. The principal feature of minimus is the very short, wide cauda, with three basal segments broader than long, and the fourth segment as broad as long. This character is shared by specimens from San Diego County, the mainland and southern Channel Islands of Los Angeles County, and the northern Channel Islands of Santa Barbara and Ventura counties. Specimens from each of these centers show differences that have prompted us to regard the complex as being derived from the same stock and representing a single polytypic species.
