Diagnosis. Body length ~ 3.30 mm in the male and ~ 3.60 mm in the female. Eye not covered with abundant setae. Tarsal formula 2-2-2. Male fore tibia straight or slightly curved ( Figs. 1B View FIGURE 1 , 21B View FIGURE 21 ). Posterior surface of male hind femur with about 6 spines basally, followed by two larger spines before middle, then about 5–6 smaller spines towards apex. Central shiny areas on dorsum of abdominal segments VII–VIII in the male and VI–VIII (sometimes also V) in the female ( Figs. 1B View FIGURE 1 , 3B View FIGURE 3 ). Male abdominal segment VIII large, longer dorsally than mediotergite VII ( Fig. 1B View FIGURE 1 ). Paramere and proctiger as in Figs. 19B View FIGURE 19 , 20B View FIGURE 20 . Female abdominal laterotergites elevated ( Fig. 3B View FIGURE 3 ).
Distribution. Colombia: Cauca ( Polhemus & Manzano 1992), Chocó ( Molano et al. 2018), Nariño (Padilla-Gil 2010, Padilla-Gil & Arcos 2011, Padilla-Gil 2012), Valle del Cauca ( Polhemus & Manzano 1992) ( Fig. 22B View FIGURE 22 ).
Comments. During our visit to the ICN, we were able to examine the types of several Rhagovelia species described by Padilla-Gil. After thoroughly studying this material, we noticed that these descriptions and the poorly prepared accompanying drawings can be very far from the reality. The measurements provided in the descriptions are particularly problematic and are always distinctly greater than those we obtained from the specimens. Finally, male proctigers and parameres can also be very different from those depicted in the descriptions, and not necessarily drawn from their usual perspectives, i.e. dorsally for proctigers and laterally for parameres. Considering these issues, the first synonymy that we must propose is between R. aguaclara and R. colombiana . After examining the types of both species and additional material, we found no significant differences between them, only minor coloration variations that are common to occur intraspecifically in this group. The differences in the paramere shape of the two species (compare Polhemus & Manzano 1992: Fig. 53 and Padilla-Gil 2010: Fig. 7 View FIGURE 7 ) are due to problems in the positioning of the structure and preparation of the drawings by Padilla-Gil (2010).
