Type material. Holotype ♁: Ecuador, Yanayacu Biological Station, 4 km west of Cosanga , Napo Province, 2160 m, 20 January 2009, J. S. Miller, D. Wagner and R. Tapia, ( USNM) Paratypes: 2 males. Same data as holotype except 18 January 2009. ( BMNH, JBS).

Etymology. Campatonema yanayacua is named for the type locality, Yanayacu Biological Station, Napo, Ecuador.

Diagnosis. This species is readily recognized by the shape of the forewing PM line, which has an outward deflection at M3 that allows it to be distinguished from the other species of Campatonema .

Description. Male. Head – Palp slightly longer than width of eye; mid-segment longer than first and about 4 × length of third; first two segments light brown outwardly with scattered chocolate scales. Cream scaling just below third segment with a few brown and chocolate scales dorsally. All segments with cream scaling inwardly. Frons squared with cream scales near palps and a mixture of brown and chocolate scales over the upper 80 %. Area between antennae with scales cream, erect; collar cream with brown scales adjacent to thorax; thorax cream with scattered brown scales. Antenna fasciculate, segments flared distad with bristle rows at middle and at distal end; antenna brown dorsally with two scale rows per segment. Thorax and abdomen – Abdomen cream with brown bands of varous shades; Abdominal segments cream basally becoming pale-brown posteriorly with white ring on posterior margin. Underside cream with scattered brown scales. Forelegs with brown scaling dorsally, cream ventrally. Hind tibia slightly swollen. Two pairs of tibial spurs on hind leg, one pair on middle legs. Wings – Forewing length 15−17 mm. PM line a double brown line, outer element fading on lower half of wing, middle part of PM line with blue gray; PM line expanded outwardly to form dark-brown wedge-shaped patch at forewing apex; medial area with a diffuse

brownish-gray band along inner margin of PM line. Costa brown basally becoming tan throughout mid-section and fusing with PM line at apex. Wing margin with row of chocolate scales forming terminal line, slightly wider at veins. Discal dot distinct. Hindwing with a series of tan and brown lines parallel to margin and crossing cream ground; brownish-gray PM line with blue-gray filling prominent. Margin a broad brown band. Ventral surface cream with chocolate PM line on costal half of forewing. Wing apex almost white. Discal dots distinct. Brown scaling over cream ground color particularly strong in costal area. Male genitalia – Uncus rod shaped, valves elongate, tapering to a rounded apex. Costa heavily sclerotized, with a slight bulge 1/3 from apex. Costal half of valva with fine setae, without processes or well-defined ridges. Gnathos arms poorly defined, medial junction a well-defined pad covered with bristles or spines. Furca deflecting to right and extending to slightly above medial pad on gnathos. Outer third of furca with bristles. Furca slightly S-shaped, tapering little from base to rounded tip. Saccus slightly rounded. Aedeagus diameter increasing posteriorly before ending abruptly in a narrow spine; lightly sclerotized, particularly anteriorly. Everted vesica expanded slightly with a patch of 8 cornuti. Pelt without distinct features. Female. unknown.

Distribution. Known only from the type locality, Yanayacu Biological Station, Ecuador.

Remarks. Similar specimens have been collected at Estacion Cientifica San Francisco, Zamora-Chinchipe, Ecuador by Gunnar Brehm. Pictures of the adults and dissections of the genitalia were examined, but differ enough from the Yanayacu specimens that they are not included in the type series.
