Gertsch & Soleglad 1972:
holotype from Malibu, Los Angeles County, California, June 14, 1954 (W. J.
Gertsch, V. Roth), in collection
of the American Museum of Natural History..
Gertsch & Soleglad,
reddish brown species similar to williamsi, distinguished by following
combination of characters: total length of male 30.8 mm., median ocular
tubercle situated well in front ofmiddle ofcarapace; pectinal tooth
count of male 11; lower margin of movable finger of chelicera smooth;
inferior lateral and median keels of cauda granulated; vesicle of sting
lightly inflated at apex.
COLORATION: Dusky to reddish brown scorpion with underside of preabdomen,
legs, chelicerae, and telson yellowish.
STRUCTURE: Like that of williamsi except as indicated. For measurements,
see table 4.
Carapace: Entire surfaces granulated; frontal lobes with six short
bristles. Frontal emargination a quite deep, rounded notch. Median eyes
small, 0.19 mm., separated by their diameter. Lateral eyes two; third
Preabdomen: All tergites granulated, those in front finely, posterior
ones more coarsely, with largest granules along posterior edges;
scarcely any traces of median keels apparent. Tergite VII with
well-developed median and lateral keels and numerous granules in
intercarinal spaces. Sternites I-IV smooth; sternite V lightly granulose
on each side and with weak lateral keel represented by row ofsmall
Cauda: First caudal segment about as broad as long; succeeding one
progressively longer than broad; segment V slightly longer than
carapace. Keels on all surfaces prominent and granulated.
Telson: See figure 124. Vesicle elongate oval, broader than fifth caudal
segment, flattened above, and weakly inflated in front of sting, mostly
smooth but with light, round granulation below and on sides. Sting less
than half as long as vesicle.
Pectines: Middle lamellae, seven or eight; pectinal tooth count, 11.
Chelicerae: Teeth sharper and more distinctly formed than those of
williamsi; lower margin ofmovable finger smooth.
Pedipalps: All keels prominent, more finely granulated than those of
williamsi; superior keel lightly crenulated in lateral view. Inner view
of fixed finger as shown in figure 121.
Walking legs: Setation like that of mordax; ventral line of spinules on
tarsi flanked by three or four spines on each side."

Gertsch and Soleglad (1972) derived
the species name "from Latin angelus, angel." Williams (1976) listed V.
williamsi (Gertsch & Soleglad, 1972) as a junior synonym of this
species. Later, Williams & Savary (1991) regarded this taxon as a separate
