Type Material

 

            Holotype: “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” (Muma & Brookhart, 1988, p. 15).

 

            Measurements: “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” (Muma & Brookhart, 1988, p. 16).

“Females (11) also variable in size; CP varies from 9.3-12.5 (mean 11.0). Legs short; A/CP 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)” (Muma & Brookhart, 1988, p. 16).

 

            Ctenidia Description: Males distinguishable by 2-5 short, slender ctenidia (Muma & Brookhart, 1988). “Most specimens examined had only 2-3 short ctenidia; 1 had 2 long ctenidia and 1 had 5 long ctenidia” (Muma & Brookhart, 1988, p. 15).

            

            Operculum Description: “Females distinguished by abruptly tapered anterior lobes of the opercula, convex lateral margins of posterior opercular notch and narrow, crescentic vulvular opening” (Muma & Brookhart, 1988, p. 15).

            

            Chelicerae Description: “frequent absence of anterior intermediate tooth of movable cheliceral finger, and laterally distinct ventral notch of the movable cheliceral finger…Dorsal process of fixed cheliceral finger peaked over basal half of fondal notch” (Muma & Brookhart, 1988, p. 15).

 

Diagnosis: “This species has affinities with 2 other species of this series. It is similar in coloration, size and general morphology to palpisetulosus 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” (Muma & Brookhart, 1988, p. 16).
