Specimens of this species labelled cotypes are in the USNM and two specimens on slide No. 5078 were used for the preparation of these drawings.
Notes: SO Ant III as in Fig. 117. Ant IV subapically with trilobed sensory knob, 4 stout curved sense rods, numerous tapering, slightly curved, sense rods, and longer setae (Fig. 118). Front feet (Fig. 121) with two tenent hairs, others with three, all in line across tibiotarsus; base of claw and unguiculus granulated; PAO with four horizontal lobes and an erect lobe rising above the others (Fig. 116); rami of tenaculum with three barbs, corpus naked; dens (Fig. 119) posterior face coarsely granulated, the remainder much finer, the posterior face with five simple setae. Mucro (Fig. 120) with finely granulated broad inner lamella and small plain basal lamella; anal spines small, and separated on subequal papillae.
From my study of this material and of the descriptions given by Schaeffer (1900), Folsom (1899), Stach (1949) and Yosii (1960), I have concluded that both Schaeffer's and Stach's material is conspecific with that of Folsom's.
