ANAPISONA GERTSCH

Anapisona Gertsch, 1941, p. 4 (type species by original designation Anapisona simoni Gertsch ).

Diagnosis: Specimens of Anapisona can be distinguished from other anapids by the single recurved distal apophysis on the male palpal femur (fig. 20), the dorsally elongated male palpal tibia (fig. 21), the presence of one or more stiff distal bristles on the cymbium (fig. 23),and posterior tracheae supplying the cephalothorax from a spiracle immediately in front of the spinnerets (Forster, 1958,figs. 24, 26).

Description: See Gertsch (1941) and Forster (1958). Illustrations are presented here of the habitus (figs. 1-3), chelicerae (fig. 6),tarsal claws (fig. 7),and anterior labral spur (fig. 10).

Species: Gertsch (1941) has supplied a detailed description of A. simoni which can be supplemented as follows: soft portions of abdomen with few sclerotizations; from above, posterior eye row slightly recurved; chelicerae with a retromarginal tooth and anterior knobs (fig. 2); femur I with ventral setae arising from tubercles; posterior spiracle precedes six spinnerets with tiny colulus. Only differences from A. simoni are noted in the descriptions below.
