The majority did not fit descriptions of any known species, except T . cf. capaira ( two specimens ) resembles T. capaira described by Trivinho-Strixino & Strixino (2007) from Brazil , but appears a bit different; T . sp. ZUR-8 ( one specimen ) is also similar to T . cf. caipira but is much smaller. Tanytarsus sp. ZUR-5 ( 16 specimens ) is similar to T. cotopaxi Giłka & Zakrzewska , described from Ecuador ( Giłka & Zakrzewska 2013 ). The majority of specimens were T . sp. ZUR-1 ( 47 specimens ), including an intersex specimen; 23 specimens of T . sp. ZUR-2; 34 specimens of T . sp. ZUR-3; 14 specimens of T . sp. ZUR-6; and one specimen of T . sp. ZUR-7.
