Costatrichia rovidka ( Oláh & Flint 2012) new combination

Acostatrichia rovidka Oláh & Flint 2012: 153 , figs. 29–31, male; type locality: Guyana: Moco-Moco, 30 km East Lethem,

3°18.2’N, 59°39.0’W; type depository: NMNH.

Material examined: HOLOTYPE male: Guayna : Moco-Moco, 30 km East Lethem, 3°18.2’N 59°39.0’W, 3– 6.IV.1994, taken by net in daytime, leg. O.S. Flint Jr. ( NMNH) . PARATYPES: Guyana, Karanambo, Rupununi River , 3°45.1’N, 59°19.6’W, 31.III-2.IV.1994, at MV light, O.S. Flint Jr. 3 males, pinned ( NMNH) .

Remarks. Although the specimens have simple antennae, they have the reflexed costal vein on each forewing, typical of Costatrichia species. Male genitalia are also more similar to the Costatrichia pattern than to any Acostatrichia . The species is probably related to C. hamulifera ( Flint 1983) and therefore it is being transferred to Costatrichia .
