Apterous male ( Fig. 1a View Figure ). Color. Body dark brown to black; dorsum centrally covered by short silvery setae. Antenna brown with base of antennomere I light yellow. Pronotum brown with a central rectangular orange spot occupying half of its width. Coxae and trochanters light yellow. Fore femur yellow from base to middle, distal half brown; middle femur brown, lighter at apex; hind femur dark brown with yellowish brown stripe on dorsum and venter, apex brown, tibia and tarsus dark brown in all legs. Abdominal terga and sterna dark brown.

Structure. Head short, shining black at insertion of trichobothria and a triangle formed by minute dots on vertex, with long setae along mesal margins of eyes. Two ocular setae present. Antennomere I with five long robust setae ( Fig. 2a View Figure ); II with long robust setae at middle. Pronotum short ( Fig. 2g View Figure ), covered by long dark setae. Mesonotum hexagonal, slightly convex at center. Metanotum short, with posterior margin straight, lateral margins with shining punctations anteriorly. Legs covered by robust setae, fore tibia strongly curved ( Fig. 2c View Figure ), hind femur with a row of 19 spines on posterior surface, composed of five small spines, followed by one long spine, and 13 short spines decreasing towards femoral apex ( Fig. 2e View Figure ). Abdomen covered by golden and silvery setae; anterior margin of mediotergite I with shining punctations; mediotergites I–VI subequal in length (each 0.16), VII longer (0.24). Abdominal laterotergites slightly elevated, with rounded posterior corner. Paramere curved at middle, with apex rounded ( Fig. 3a View Figure ), covered by abundant setae on internal margin.

Etymology. This species is named after the town of Nuquí, where the type series was collected.

Geographic distribution. Known only from Chocó Department, Pacific Region of Colombia ( Fig. 4 View Figure ).

Comments. Rhagovelia nuqui  sp. nov. differs from other species of the salina  group by the following combination of characters: body length about 2.40 mm in the male and 3.20 mm in the female, posterior surface of the male hind femur with a decreasing row of 19 spines ( Fig. 2e View Figure ), and shape of the paramere ( Fig. 3a View Figure ). It may be distinguished from the other salina  group species occurring in Colombia using the key presented below. This new species was collected in freshwater with marine influence at high tide and in mangroves with moderate current, abundant surrounding vegetation, sandy bottom and numerous shaded areas ( Fig. 5 View Figure ).
