The epithet, chilensis, is used as an adjective and meaning “from Chile ” in reference to the country of origin of the holotype.</p><p>Diagnostic characters. Riethia chilensis differs from its close relative, R.truncatocaudata, by uniformly coloured legs, without bands, and curved, stout superior volsellae without microtrichia dorsally. A light brown abdomen, with darker anterior bands on the tergites, and a superior volsella without microtrichia are the characters that separate R. chilensis from the second new species described here (see below). Both new species + R. truncatocaudata can be separated from all other Riethia by having the inferior volsella strongly bent dorsally, with apical part subtriangular and dorsally covered with broad, flattened, apically fringed setae. See also the diagnosis for the second species.</p><p>Description. Adult male (n = 5)</p><p>Body size and proportions. Total length 5.21–5.71, 5.44 mm. Wing length 3.03–3.23, 3.09 mm.
