Muma and Brookhart 1988
Muma and Brookhart 1988:
Brookhart new species
35 to 39
TYPES: Male holotype from Turkey,
Texas, 21 May 1970, D. Kiser and female allotype from 6 mi. S.E. of
Turkey, Texas, 4 June 1970, D. Kiser, in FSCA.
DIAGNOSIS: Males distinguished by
their short slender ctenidia which range from 2-5 in number, frequent
absence of anterior intermediate tooth of movable cheliceral finger, and
laterally distinct ventral notch of the movable cheliceral finger. Most
specimens examined had only 2-3 short ctenidia; 1 had 2 long ctenidia
and 1 had 5 long ctenidia. Dorsal process of fixed cheliceral finger
peaked over basal half of fondal notch.
Females distinguished by abruptly tapered anterior lobes of the
opercula, convex lateral margins of posterior opercular notch and
narrow, crescentic vulvular opening.
DESCRIPTION: Most specimens examined
had been darkened by inadequate preservation but the species apparently
is pale to dusky yellow in color with the following dark purplish
markings. Palpi pale with distal
of metatarsi and all of tarsi dusky
to darker. Legs pale with little or no dusky markings. Propeltidia dark
along anterior margin with occasional specimens also lightly dusky on
to all of sclerite; some specimens
also have a narrow pale median stripe as on palpisetulosus (fig.
metapeltidia, and abdominal terga dark; pleura pale. Sterna pale.
Males (10) quite variable in size; CP varies from 8.8-13.0 (mean 11.1).
Legs moderate in length; A/CP varies from 5.8-6.2 (mean 6.0). Fondal
notches longer than wide, varying in length/width ratio from 1.3-1.7
(mean 1.4) (fig. 36). Ctenidia short and slender, varying from 2 to 5
(mean 2.4) (fig. 37).
Males have a small to medium sized mesal tooth on movable cheliceral
finger; mode medium sized.
Females (11) also variable in size; CP varies from 9.3- 12.5 (mean
11.0). Legs short; AlCP
varies from 5.0-5.2 (mean 5. 1). Females have
an indistinct to medium sized mesal tooth on movable cheliceral finger;
mode small. Opercula with anterior·lobes undulate mesally; opercular
notches occupying 30-47% of opercula (mean 37) (figs. 38-39).
: This species is presently known only from Turkey, Texas from which we
have examined 13 males and 11 females.
This species has affinities with 2
other species of this series. It is
similar in coloration, size and general morphology to
from which it
differs in location of the peak of the dorsal process of the fixed
finger; size of male ctenidia, and form of the female opercula. It is
also similar to norrisi
but differs from that species in size of male
ctenidia, profile of male chelicera, fondal notch ratio, A/CP, and form
of the female vulvular opening. Collection records indicate maturity
during May and June.
