Diagnosis. Body length ~ 2.90 in the male and ~3.00 in the female. Antennomere II shorter than III. Tarsal formula 3-3-3. Fore and hind coxae and trochanters yellow; middle coxa and trochanter black (Figs. 17C, 18A). Male fore tibia almost straight (Figs. 17C, 17D, 21B). Male hind trochanter without spines. Male hind femur slightly thicker than middle femur, with 6–7 spines (Figs. 17C, 17D). Ratio of male hind femur/tibia length ~0.94/1.00. Male hind tibia without spines or apical spur (Figs. 17C, 17D). Lateral margins of male and female abdomen tapering more or less evenly to apex (Fig. 18A). Central shiny areas on dorsum of abdominal segments VII–VIII (Figs. 17C, 18A), rarely V–VIII in the female. Female abdominal laterotergites horizontal or slightly elevated. Male abdominal sternum VII with median carina, slightly depressed on each side. Male abdominal segment VIII subcylindrical, with lateral margins bowed, shorter dorsally than mediotergite VII (Fig. 17C). Paramere and proctiger as in Figs. 19T, 20T.

Distribution. Belize (Drake & Harris 1933). Colombia: Boyacá (this work), Caldas (this work), Casanare (Aristizábal 2017), Cauca (Manzano et al. 1995, this work), Cesar (Aristizábal 2017), Chocó (this work), Meta (Aristizábal 2017, this work), Quindío (this work), Nariño (Padilla-Gil 2011, Padilla-Gil 2015, Padilla-Gil 2017), Santander (this work). Costa Rica (Moreira et al. 2015). Panama (Bacon 1956). Peru (Bacon 1956) (Fig. 27A).

Comments. Rhagovelia tantilla was known from only a few specimens (Drake & Harris 1933, Bacon 1956) until Moreira et al. (2015) examined several series collected throughout Costa Rica. This is probably why this species was not used for comparison when R. vonprahli, R. pacifica and R. tumaquensis were described, respectively by Manzano et al. (1995), Padilla-Gil (2011) and Padilla-Gil (2015). Examination of topotypical material of R. vonprahli and of the types of the last two species showed that the three are synonyms of R. tantilla, possessing all diagnostic features of the last species, which are mentioned above. The paramere of R. pacifica drawn by Padilla-Gil (2011: Fig. 33) has essentially the same shape as that of R. tantilla (Bacon 1956: Fig: 16, this work: Fig. 19T). Different shapes have been drawn for R. vonprahli (Manzano et al. 1995: Fig. 8) and R. tumaquensis (Padilla-Gil 2015: Fig. 36), but they do not correspond to what we examined in the specimens. In the former case, it seems that the paramere was squeezed and slide-mounted before being drawn, whereas in the latter the issue appears to be in the drawing itself. Rhagovelia tantilla was recorded from the same Colombian municipality from where R. pacifica and R. tumaquensis were described (Padilla-Gil 2015), and the type localities of the last two species are within the same area of the municipality (Consejo Comunitario Río Mejicano).
