TYPES:
Male holotype from
San Diego, CA, May 9, 1969 by B. J.
Kaston; female
allotype from San Diego, CA, pit traps, June 1971 by B. J.
Kaston,
both deposited in
FSCA.
DIAGNOSIS: Males distinguished by
large
triangular to rounded.
blade-like dorsal process on fixed cheliceral finger peaked over distal
half of fondal notch; fondal notch much narrower than width of base of
fixed cheliceral finger and slightly wider than deep; distinct rounded
to
subquadrate anterior
process on movable cheliceral finger; unusually distinct ventral notch
of movable cheliceral finger from lateral view (fig. 149); 17-58
papillae in basal palpal , metatarsal scopula; and 6 short to long
abdominal ctenidia on first post-stigmatic sternite (figs. 150- 151).
Females distinguished by opercula twice as wide as long; short to long,
broad, anterior, opercular lobes; small posterior opercular notch with
slightly convex lateral margins; a wide, bowed, vulvular opening located
near posterior margin of opercula (figs. 154, 155, and 156).
DESCRIPTION: Pale to dusty
yellow in color with dusky purplish markings. Palpi lightly to
distinctly dusky on all segments except pale basally on femora (fig.
157). Legs IV dusty yellow to lightly
dusky with pale metatarsi and tarsi with irregular, narrow to wide
submarginal band (fig. 157). Propeltidia dusky to dark; anterior margin
dark; with an irregular broad to narrow pale median stripe (figs.
152-153). Mesopeltidia, metapeltidia, and abdominal terga dusky with
pleura dark but lighter than tergites. Venters pale. Allotype paler than
others.
Males (6) slightly variable in size; CP varies from 9.25-9.75 (mean
9.50). Legs moderately long;
A/CP;
varies
from 6.33-6.47 (mean
6.36). Fondal notches vary from 0.78-0.89 (mean 0.82). Mesal tooth
absent or indistinct. Short abdominal ctenidia vary from 5-6 (mean 5.6).
Number of papillae in basal palpal metatarsal scopula varies 17-58 (mean
41.6). One male from Los Angeles County lacked a scopula.
Female allotype has a CP of 10.0; A/CP of 5.0,
indistinct mesal
tooth , and posterior opercular notch occupies 27% of opercular area and
is more or less triangular in outline.
DISTRIBUTION:
We have examined 11 males and 3 females from 4 localities in Los Angeles
County, Hesperia in San Bernardino County, and San Diego County most in
extreme southwestern California. Most collections were made during May,
June, and July; we have one record during September from San Diego,
California.
REMARKS:
Although this species seems to have some affinities with the
scopulatus-vicinus
complex, it is most closely related
to E.
scopulatellus,
which
tends to be a more northern form, with distinctively different markings.
