Anapisona simoni Gertsch
Figures 1-3, 16，26, 27
Anapisona simoni Gertsch , 1941, p. 6，figs. 1-4，27 (male holotype from Barro Colorado Island, Canal Zone, Panama, in AMNH, examined). Forster, 1958, fig. 24.
Diagnosis: Males of A. simoni may be recognized by the subterminal bristles on the cymbial extension (fig. 16)，females by the narrow, triangular epigynal openings and highly coiled ducts (figs. 26，27).
Male: Described by Gertsch (1941). Female: Described by Gertsch (1941). Variation： Because this is the only species of Anapisona for which an adequate sample from one locality is known, variability in the cusps on leg I was studied. In males, the first tibia usually bears a single cusp at about half its length, but it may be lacking on the right or left leg and is occasionally doubled; the first metatarsus usually has one median and two distal cusps but the median and one of the distal cusps may be lacking. In females, only a few specimens have a tibial cusp, and most have one median and one distal metatarsal cusp (although the median cusp may be missing and the distal cusp is rarely doubled).
