Diagnosis. Males of Eutichurus tropicus (L. Koch, 1866) resemble those of Eutichurus valderramai Bonaldo, 1994 and Eutichurus andresgarcia sp. nov. in having a filiform embolus and a short, excavated retrolateral tibial apophysis ( Fig. 7A–C View FIGURE 7 ; Bonaldo 1994: figs 43–45, 48–49). Additionally, they closely resemble the latter species by having the embolus abruptly narrowing from the distal half. They differ thoseby having the embolus inserted almost basally and with a prolateral embolar process situated medially. They also resemble E muisca sp. nov. in having an excavated RTA and a median apophysis with apMA and aMA of nearly equal length, projecting similarly toward the basal and distal sides of the cymbium, respectively ( Bonaldo 1994: 150, figs 43–45, 151, figs. 48–49; Figs 4A–C View FIGURE 4 ). However, they can be distinguished by having a wider, nearly square aMA with a longitudinal medial keel, a narrower, tapering aMA, and an RTA nearly perpendicular to the tibia respectively ( Bonaldo 1994: 150, figs. 43–45, 151, figs. 48–49; Figs. 5A–C View FIGURE 5 ). Females see Bonaldo (1994: 119).

Description. See Bonaldo (1994: 119 – male under E. brescoviti ). Additional documentation in Figs 7 View FIGURE 7 , 29B View FIGURE 29 , 30B View FIGURE 30 .
