Legs 1 and 2 display four pairs of stouter, dark spines on the ventral tibia, with a shortened metatarsus. Leg 3 displays 2 pairs of the dark, stout spines on each of the ventral tibia and metatarsus. Leg 4 displays 2 pairs of the dark, stout spines on the ventral tibia, and scattered dark, stout spines on the ventral metatarsus. Regarding trichobothria, the key in Ubick et al. (2005), pp. 33-35, gives the analyst three choices: (1) 0-1 trichobothria, (2) 2 or more with trichobothria in a single row, and (4) 2 or more with trichobothria scattered. Microscopic analysis shows this specimen falls under the third choice, which--along with a low clypeus and strongly recurved PER and PLE posterior to PME, points us to the Lycosidae ----FINIS---- PAGE 1 * 2 * 3 * 4 * 5 * 6 *
