Costatrichia nelsonferreirai Santos & Nessimian 2010 

Costatrichia nelsonferreirai Santos & Nessimian 2010: 838  , figs. 1–8, male; type locality: Brazil, Pará: Canaã dos Carajás (Floresta Nacional—FLONA—de Carajás, lagoa Redonda, 06°21’20.7”S, 50°23’26.7”W, 705 m); type depository: DZRJ.

Acostatrichia ketvilla Oláh & Flint 2012: 149  , figs. 19–21, male; type locality: Brazil: Pará State, Rio Xingu Camp, circa. 60 km South Altamira, 52°22’W, 3°39’S; type depository: MZUSP. NEW SYNONYM.

Material examined. Costatrichia nelsonferreirai  : HOLOTYPE male: Brazil, Pará: Canaã dos Carajás (Floresta Nacional—FLONA—de Carajás, lagoa Redonda, 06°21’20.7”S, 50°23’26.7”W, 705 m).GoogleMaps 

Acostatrichia ketvilla  : PARATYPE: Brazil: Pará State, Rio Xingu Camp, circa. 60 km South Altamira, 52°22’W, 3°39’S, 13–21.X.1986, leg. P. J. SPANGLER & O. S. FLINT, Jr. 1 male, pinned ( NMNH).

Remarks. Costatrichia nelsonferreirai  was described from northern Brazil (Pará State), as the same state as Acostatrichia ketvilla  . In the original description of A. ketvilla  , a small bulla on each forewing costal vein and “no dilatation” on antennal articles were mentioned ( Oláh & Flint 2012). However, examination of a paratype revealed a typical antennal modification of Costatrichia  species: the median articles of the antennae are flattened and expanded dorsoventrally. In addition, the forewing shows a conspicuous reflexed costal vein, another Costatrichia  feature. There are no differences in the male genitalia of these two named species, so that I propose here the subjective synonymy of Acostatrichia ketvilla  with senior synonym Costatrichia nelsonferreirai  .
