Female holotype: total length, 3.4, width, 1.9. Color pale tan to yellowish brown. Carapace arcuate, about 1.5X as wide as long, with complete lateral and posterior submarginal keels; pair of median keels connecting eye tubercle and innermost lateral hood process, lateral keels arising both on innermost and middle lateral hood processes. Two blunt lateral hood processes each about one-half as long as median hood process. Circumocular keels suppressed, but subocular portion obvious, eyes relatively large, bulging. Median hood process arising dorsally on eye tubercle, with nearly parallel sides, then converging distally, widest slightly beyond midlength, length 1.10, width 0.45; median keels of carapace continuing as rows of lateral tubercles on median hood process, about 20 lateral tubercles, linearly connected; about 15 dorsal tubercles present, connected complexly to one another and to lateral tubercles. Metapeltidium free, complete keel along anterior margin, 6 tubercles posterior to keel, connected to it by single branch each. Scute 1.8 long, 1.9 wide. All keels relatively low. Small keel cells present on areas 1-4; area 1 with 2-3 small cells in midline, area 2 with 4-6 small cells in transverse row less than

(Fig. 16) with basal article 0.70 long, 0.23 wide, sparsely setose; second article 0.72 long, 0.20 wide. Palpus (Fig. 25) slender, with dense vestiture of clavate setae; trochanter with two prominent seta-bearing ventral tubercles; dimensions given in Table 8. Legs in order of length, 2 (14.05), 4 (9.43), 3 (5.90), 1 (5.73); metatarsus 2 with about 12 false articulations, femora without false articulations; tarsi 1-4 with 6, 12, 6(7), 9 articles respectively. Lengths of leg segments given in Table 8. Length/width ratios of femora, in order: 8.25, 36.8, 9.0, 28.2. Leg femora with typical ornamentation.

The entrance is large enough that sufficient light reaches the floor to sustain a plant community (P. Sprouse, pers. comm.).</paragraph>
