tactile seta on tibia and basitarsus. Subterminaltarsal setae denticulate.Tritonymph.-Similar to adults but less heavilysclerotized, smaller, and with less slender appendages.Carapace without the transverse furrows soevident in adults; 4 corneate eyes, posterior pairsmaller; 6 setae at anterior and 7 at posteriormargin. Chelicera with 5 setae on hand and 5 setaein flagellum. Palp with femur 3.65, tibia 2.45, andchela (without pedicel) 3.0 times as long as broad.Fixed chelal finger with 46 and movable finger with44 marginal teeth; movable finger with sensillum onlateral surface between trichobothria st and b, closerto st; the paratype without a proximal "denticle" onthe dental margin. Leg IV with entire femur 3.0times as long as deep.In addition to the paratype tritonymph, there is athand a very similar tritonymph from H.T. Miers<strong>Cave</strong>, Del Rio, Val Verde County, Texas, 29 January1984 (P. Sprouse); mounted on slide (FSCA).Measurements (mm).-Adults: Figures givenfirst <strong>for</strong> holotype, followed in parentheses by those<strong>for</strong> paratype. Body length 3.84 (3.83).
