Achaearanea schneirlai Levi, 1959: 67  , fig. 26, male holotype, from Barro Colorado Island, Panama, 30/ IV/1946, T. C. Sch- neirla leg., deposited in American Museum of Natural History, not examined.

Cryptachaea schneirlai: Yoshida, 2008: 39  (transferred to Cryptachaea  ).

Diagnosis. The female is similar to that of Cryptachaea dea ( Buckup & Marques, 2006)  (see Buckup & Marques, 2006: 64, figs. 5, 6) by the larger and oval spermathecae, and by presence and the shape of atrium ( Fig. 7View FIGURES 5–8), but differ by the spermathecae close to each other, and by the shape of fertilization ducts forming a handle ( Fig. 8View FIGURES 5–8).

Description. Male described by Levi (1959: 67). Here we provide the first illustration of the male body in dorsal view ( Fig. 13View FIGURES 9–14).

Female ( IBSP 174303): Total length 3.45. Carapace: length 1.37, width 1.09. Clypeus: height 0.18. Sternum: length 0.78, width 0.70. Chelicerae: length 0.44, width 0.20. Abdomen: length: 1.89, width 1.61, height 1.87. Segment length (I/II/III/IV): femora 1.82/1.43/1.06/1.84; patellae+tibiae 1.27/0.83/1,56 (absent leg I); metatarsi+tarsi 1.69/1.30/2.08 (absent leg I). Palp: femora 0.33, patellae 0.13, tibiae 0.18, tarsi 0.39. PME bigger than the other eyes; other eyes are the same size. Eyes with dark borders ( Fig. 14View FIGURES 9–14). Carapace oval, dark brown ( Fig. 14View FIGURES 9–14). Clypeus brown, laterally concave. Chelicerae brown. Labium yellow, subquadrangular. Endites brown, subquadrangular. Sternum dark brown. Legs yellow, except distal femur and tibiae apex with dark brown spot. Abdomen dorsally dark brown, with two laterals triangular and one posterior dark spots ( Fig. 14View FIGURES 9–14) and with median and posterior white spots ( Fig. 14View FIGURES 9–14); ventrally yellow, with dark brown and white dots. Spinnerets brown. Epigynum with epigynal plate wider than long ( Fig. 7View FIGURES 5–8), with an atrium horseshoe-shaped, two oval spermathecae ( Fig. 8View FIGURES 5–8), fertilization ducts form a handle ( Fig. 8View FIGURES 5–8).

Variation. Females (n=3): Total length 3.45–3.64. Carapace: length 1.37–1.30, width 1.09–1.14. Femur leg I 1.82–2.21.
