Eutichurus sigillatus Chickering, 1937: 32 View in CoL , 33, figs 40, 69, 70 (Male holotype, Barro Colorado Island, Canal Zone , Panamá, 16.VI-15.VII.1934, MCZ B0072); Roewer, 1954; Bonnet, 1956: 1845; Bonaldo, 1994: 132, figs 84–88, 108.

Diagnosis. Males of Eutichurus sigillatus Chickering, 1937 are similar to those of Eutichurus putus O. Pickard-Cambridge, 1898 and Eutichurus tibacuy sp. nov. by having a trifid retrolateral tibial apophysis (see Bonaldo 1994: 155, figs 84–86, 89–91; Fig. 15B–C View FIGURE 15 , 16B–C View FIGURE 16 ). However, they can be distinguished from E. putus by the apex of median apophysis narrow and embolar apex trifid and from E. tibacuy sp. nov. by the RTA with all three branches pointed, prolateral branch of the embolus poorly developed and medial and retrolateral branches at approximately the same level ( Bonaldo 1994: 155, figs 84–86, 89–91; Fig. 15B–C View FIGURE 15 , 16B–C View FIGURE 16 ). Females are similar to those of E. tibacuy sp. nov., E. manu , E. yariguies sp. nov. and E. putus by the epigynal anterior projections small and the median field wider than long. However, they can be distinguished from E. manu and E. putus by the anterior margins of posterior plates W-shaped and from E. tibacuy sp. nov. and E. yariguies sp. nov. by having thinner anterior projections that do not extend to the anterior region of the median field and median field with a posterior median projection (with a subtriangular median depression in E. tibacuy sp. nov. and without modifications in E. yariguies sp. nov.)

Description. See Bonaldo (1994: 120). Additional documentation in Fig. 19 View FIGURE 19 .

Additional material examined. PANAMÁ, Canal Zone : 1♂, 1♀, Barro Colorado Island , A.M. Chickering leg. (MCZ). Originally identified by Bonaldo in 1992 and subsequently cited in Bonaldo (1994: 133) and confirmed here .

Distribution. Known from Panama ( Fig. 32 View FIGURE 32 ).
