Circanota undulata Brown  sp. n. Figs 1, 2, 3, 5, 7


In Circanota undulata  the valvae are short and broad, the membranous distal edge of the valva between the termination of the costa and the median lobe of the outer margin is exceedingly long, and the shape of the sacculus is unique - long and undulate, ending in a slender free spinelike process. All of these features are in strong contrast to their condition in Circanota simplex  , which has a rounded valva that is bilobed disally, and a short, narrow sacculus lacking a free distal tip. The female genitalia of Circanota undulata  have an asymmetrical anterior projection of the sterigma (= antrum) that is lacking in Circanota simplex  .


Male. Head: Vertex and upper frons uniform fawn brown, lower frons pale cream. Labial palpus fawn brown, paler on inner surface. Antenna pale fawn brown, slightly darker on scape. Thorax: Tegula and notum fawn brown. Forewing length 4.9-5.5 mm (mean 5.1; n = 6), fawn brown mixed throughout with pale orange brown, with faint, narrow, variable traces of slightly darker post-median and subterminal faciae, and a few short darker strigulae along costa; well developed costal fold occupying straight basal 0.4 of costa. Hindwing uniform dark gray brown. Abdomen: Genitalia (Fig. 5) with uncus long, slender, uniform in width throughout, hooked ventrad in apical 0.25; socius rather short, narrow, with slender line of sclerotization along inner edge, bearing long dense scales, secondary arm long, slender, not expanded apically; transtilla weakly expanded mesially with a single small median spine; valva broad, short, with costa short, well defined; an irregular “notch” extending from distal end of costa to lobe-like process near middle of outer margin of valva; sacculus well-defined, confined to basal edge of valva, undulate with a long, free, weakly curved spine at termination, a rounded excavation between tip of sacculus and lobe at middle of outer margin of valva. Phallus long, slender, undulate, nearly uniform in width throughout, with phallobase slightly expanded; vesica with a field of about 25-30 short, slender, deciduous (based on presence in female ductus bursae), asciculate cornuti.

Female. Head and Thorax: Essentially as described for male, except forewing length 5.0-5.9 mm (mean 5.5; n = 6) and forewing slightly darker overall. Abdomen: Genitalia (Fig. 7) as described for genus; sterigma a sclerotized fig, flat along posterior margin, slightly rounded anteriorly, confluent with an angulate-rhomboidal mesal portion at junction of sterigma and ductus bursae (typically the cup-shaped portion of the sterigma); ductus bursae uniformly narrow throughout, slightly longer than corpus bursae; ductus seminalis arising from ductus bursae ca. 0.33 distance from ostium to junction with corpus bursae; corpus bursae round, signum a ribbon-like, crescent-shaped sclerite, nearly uniform in width.

In neighbor-joining trees, barcode sequence data from Circanota undulata  (n = 12 field collected adults) form a tight cluster with genetic divergence of less than 0.1% among the individuals.

Distribution and biology.

Circanota undulata  is recorded from Costa Rica and Panama below about 900 m elevation. All the specimens were collected between January and May.


The specific epithet refers to the undulate costa of the forewing.
