All paratypes on tree trunks covered with lichens and mosses.

Diagnosis.

Forewings hyaline, without marginal pigmented band as in C. candelaria sp. n., and C. chicaque sp. n., differing from them by having the forewing M four-branched (Figure 19), and the hindwing M three-branched (Figure 20), and by details of the phallosome and hypandrium.

Male.

Color (in 80% ethanol). Body cream to pale brown, with pigmented dark brown areas as indicated below. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Vertex with dark brown spots, central and lateral between compound eyes. Front with brown spots between ocellar group and epistomal sulcus, as illustrated (Figure 21), with pale cream band parallel to the antennal sockets. Postclypeus brown, with diagonal pale brown bands. Anteclypeus and labrum pale brown. Genae brown. Postgena pale cream. Antennae brown, flagellomeres cream apically. Maxillary palps pale brown, Mx4 dark brown distally. Tergal lobes of meso- and metathorax dark brown; thoracic pleura dark brown with pale spots. Legs pale brown, coxae with brown spots basally, femora with gray-brown ring basally and gray-brown spots widely distributed; tibiae with gray-brown spot, tarsi 1 brown apically; tarsi 2-3 brown. Wings hyaline, forewing pterostigma with one distal large dark brown band, some with additional proximal spot (not illustrated). Abdomen pale cream, with subcuticular bands brown; clunium and hypandrium brown; clunium with pale central area, hypandrium anteriorly cream; phallosome brown, with sclerites dark brown; epiproct and paraprocts brown.

Morphology.

As in diagnosis, plus the following: Head elongate (Figure 21): H/MxW: 1.44; H/D: 3.1, H/d: 4.19; IO/MxW: 0.78. Outer cusp of lacinial tip broad, with nine denticles. Mx4/Mx2: 1.10. Forewings (Figure 19): L/W: 2.69. Pterostigma elongate: lp/wp: 6.91, areola postica tall, triangular, with apex rounded: al/ah: 1.52; M four-branched. Hindwings (Figure 20): l/w: 3.02; M three branched. Hypandrium with three pigmented, setose areas, the two anterior widely separated and weakly connected to the posterior area, the latter narrow and extended laterally as a boomerang of little curvature (Figure 22). Phallosome (Figure 24) with laminar external parameres, wide, with apically rounded lobe bearing pores, curved inwards; mesal sclerite process with curved outwards apical teeth as illustrated. Side struts V-shaped, basally with an attached complex structure that projects over the hypandrium, distally curved outwards. Anterior endophallic sclerites laminar and oval, with serrate anterior margin, lateral sclerites curved as illustrated. Paraprocts (Figure 23) almost elliptic, with a distal setal field; sensory fields with 24 trichobothria on basal rosettes. Epiproct (Figure 23) semi-oval, rounded posteriorly, setal field with setae and macrosetae, posterior margin with small setae as illustrated.
