Kisutam rosemary Thompson & Robbins, new species, is described in subtribe Calycopidina from montane forest (2000 m) along the road from Boquete to the summit of Volcan Barú, Chiriquí, Panama. The species is also recorded from Cerro Totuma (Chiriquí) and from Volcan Poas, Costa Rica. Genus Kisutam now contains two allopatric Central American montane species (K. rosemary, K. micandriana) and one widespread, primarily lowland species (K. syllis). The larval food of K. rosemary is unknown, but is presumed to be forest floor detritus, as is true for K. syllis and for most of the Calycopidina. The genitalia and 8^th abdominal tergum of K. rosemary and K. micandriana are symmetrical and possess brush organs, which modifies the previous characterization of Kisutam.
