Material Examined

. California, Stanislaus Co., Modesto; lawn;
29 September 1961
; H. Sinclair, coll.
Holotype
on one slide, California Department of Agriculture # 61J2–105, deposited at the California Academy of Sciences (entomology
type
# 15020).
Description
: The following additions to the description of the species are based on the
holotype
. Length of
holotype
1.1 mm. Colour pattern not seen but originally described as shown in
Fig. 42
. Ant. 1 with 2 dorsal macrosetae. Prelabral setae 2. Postlabial column CG obstructed, but apparently all setae ciliate. Tergal macrochaetotaxy of Th. 2–Abd. 2 as 4, 6, 4, 2 (
Figs. 25–26
): chaetotaxy of Th. 3 and Abd. 1 arranged as in
S. bidentata
. Abd. 4 with 4 posterior setae. Trochanteral organ with 13+14 setae. Unguis with only one distal unpaired tooth. Collophore anterior face with 3 macro- and 3 microsetae; lateral setae 15; posterior face with 1+1 setae. Proportions of dens/manubrium≈ 1, proportion dental vesicle/mucro ≈ 1. Mucro with basal dorsal denticle.
Remarks
:
Salina beta
has a unique colour pattern that distinguishes it from all other New World species. In chaetotaxy
S. beta
is intermediate between
S

wolcotti

ventricolor
and
