Diagnosis. Males of Eutichurus putus O. Pickard-Cambridge, 1898 are similar to those of Eutichurus tibacuy sp. nov. and Eutichurus sigillatus Chickering, 1937 by having a trifid retrolateral tibial apophysis ( Bonaldo 1994: figs 89–91, 84–86; Figs 15C View FIGURE 15 , 16C View FIGURE 16 , 17A View FIGURE 17 , 18C View FIGURE 18 , 23C View FIGURE 23 ). They can be distinguished by the broadened median apophysis and the bifid tip of the embolus (trifid in E. sigillatus and E. tibacuy sp. nov.), and by having the ventral and medial branches of the retrolateral tibial apophysis longer, more developed, and sharper, with the dorsal branch clearly separated from the medial branch (shorter ventral and medial branches, with dorsal branch closer to the medial branch in E. sigillatus and Eutichurus tibacuy sp. nov.) ( Bonaldo 1994: figs 89–91, 84–86; Figs 15C View FIGURE 15 , 16C View FIGURE 16 , 17A View FIGURE 17 , 18C View FIGURE 18 , 19C View FIGURE 19 , 20C View FIGURE 20 , 21C View FIGURE 21 , 22D View FIGURE 22 ). Females resemble E. sigillatus and E. manu by having small anterior projections, which do not surpass the anterior margin of the posterior plates, and by having posterior plates that are longer than wide ( Bonaldo 1994: figs 92, 87, 82; Figs 18F View FIGURE 18 , 20D View FIGURE 20 ). Additionally, they resemble the latter species by having a smooth atrium without a median protuberance ( Bonaldo 1994: figs 92, 87, 82; Figs 18F View FIGURE 18 , 23D View FIGURE 23 ). However, they differ from these species by having the anterior margin of the posterior plates straight ( Fig. 17F View FIGURE 17 ) (W-shaped in E. sigillatus and slightly oblique relative to the posterior plates in E. manu ), and the atrium subquadrate, almost as wide as long (hexagon-shaped in E. sigillatus and sub-rectangular, almost longer than wide ( Bonaldo 1994: figs 92, 87, 82; Figs 17F View FIGURE 17 , 23D View FIGURE 23 ). Furthermore, they exhibit SS2 that are not significantly different in thickness from the spermathecae, being almost the same thickness, and by having elongated secondary spermathecae, resembling a banana ( Bonaldo 1994: fig. 93; Figs 23F View FIGURE 23 , 20D View FIGURE 20 ).

Remarks. Eutichurus putus O. Pickard Cambridge, 1898 was established based on a female collected in Veraguas, Panama. The status of the species was based on this specimen, until Bonaldo (1994) included new additional material. One of these was a female previously described as E. ecuadorensis Schmidt, 1971 , which, after examination of the type specimen, was considered as synonymous with E. putus . In addition, Bonaldo included 14 other specimens (12 of which were adult males) from Panama, Colombia, and Brazil: three males and two females from Barro Colorado, Panama; four males and two females from Estrada Chiva, Panama; one male from Cali, Colombia; two males from Maracá Island, Northern Brazil; one male from Rondônia, and one male from Mato Grosso do Sul ( Bonaldo 1994). Bonaldo (1994) first described the male of E. putus from a specimen from Island Maracá, Brazil, and described a female from Barro Colorado, Panama. However, Maracá is very far from Veraguas, Panama (the type locality of the species), separated by a significant geographical barrier such as the tropical Andes ( Fig. 28 View FIGURE 28 ). Several differences were observed in the new material examined in this study. The specimens from Sucre, Colombia ( Figs. 21–22 View FIGURE 21 View FIGURE 22 ) correspond to those from Barro Colorado, Panama ( Fig. 17 View FIGURE 17 ), while the specimens from Palmira, Colombia ( Fig. 20 View FIGURE 20 ) correspond to those from Cali ( Fig. 18 View FIGURE 18 ). These last two localities are very close to each other (department of Valle del Cauca, Colombia) ( Fig. 28 View FIGURE 28 ). Regarding the females, we present here a specimen from Palmira, Valle del Cauca ( Fig. 25 View FIGURE 25 A-E), which shows differences compared to the description of Bonaldo (1994) from Panama females, such as the anterior margins of the posterior plates slightly W-shaped (straight in the Panama specimens; Bonaldo 1994: 133, fig. 92; Fig. 22F View FIGURE 22 ). Since this female was collected with a male corresponding to those from Cali, Colombia, we believe that it may also be the female corresponding to that material. Based on the above, it is likely that the individuals identified as E. putus from Barro Colorado, Panama, and Cali, Colombia, represent two different entities or simply a notable variation of the same species. However, it is necessary to review the remaining material provided by Bonaldo (1994). Furthermore, it is crucial to include molecular tools based on DNA sequences, such as the COI gene, to make a more robust decision.
