Anacroneuria tunasi sp. nov., Stark & Zúñiga

( Figs. 32-36 )

Material examined. Holotype ♂ from COLOMBIA, Risaralda, Municipio de Santuario, Parque Nacional Natural Tatamá , 2400 m, November 2004, on vegetation, J. Castellanos ( MEUV).

Adult habitus. General color yellow brown patterned with brown, head yellow brown with dusky brown area from ocelli to forward of M-line; M-line represented by oval median spot ( Fig. 32 ). Pronotum with irregular dark lateral bands and wide median pale band. Wing membrane with pale brown tint and brown veins, R vein darkest. Femora dark on dorsum and in narrow apical band; tibia uniformly dark brown.

Male. Forewing length 12 mm. Hammer thimble shaped, height subequal to basal diameter ( Fig. 33 ). Aedeagal apex trilobed with shoulders projecting as ear-like structures ( Fig. 34 ); dorsal keel a minute triangular projection ( Fig. 36 ). Apical area in lateral aspect about as wide as long; ear-like lateral lobes reach beyond midpoint to ventral margin ( Fig. 35 ).

Female. Unknown.

Larva. Unknown.

Etymology. The species name, used as a noun in apposition, honors the indigenous people who inhabited this region in Colombia.

Diagnosis. The aedeagus of this species is similar to that of A. citara (described above) and related species. It differs from the related species ( A. albimacula and A. rugosa ) on the same basis as A. citara , and it differs from that species in having a much smaller apical aedeagal area, in the absence of small basal ear lobes and in the sinuate dorsal connection of the lateral ear lobes to the apex. In A. citara this connection is more linear ( Fig. 36 ).

Ecological notes. The specimen was collected near the type locality of A. tatama . This National Natural Park is one of the best protected areas in Colombia and is located in the west part of Región Natural Andina in an area with rugged topography .
