Zonana DeLong & Freytag, 1963

Diagnosis. Body ( Fig. 12 ) not strongly depressed; crown, frons, pronotum and basal half of clavus of forewing with brown or dark-brown punctures. Head with transocular width ( Fig. 11 ) narrower than maximum pronotum width. Crown with median length approximately half of interocular distance. Ocelli ( Fig. 11 ) anterior to imaginary line between anterior eye angles and closer to midline than to adjacent eye. Transition crown-face ( Fig. 12 ) distinct and foliaceous. Frons ( Fig. 1 ) with parallel transverse black bands over muscle impressions. Gena ( Fig. 1 ) with inferior margin convex. Forewing ( Fig. 2 ) with basal half of clavus coriaceous* and conspicuously punctate. Profemur with AD, AM and PD rows reduced and poorly defined, with exception of apical setae AD1, AM1 and PD1, respectively*; AV and PV rows with few sparse setae, with numerous small setae between AV and PV rows, AV row restricted to proximal half and PV row extended entire length of femur*; IC row formed by slightly arched comb of fine setae, beginning at distal half of femur and extending to AM1*. Protibia without longitudinal intercalary carinae; with four rows of macrosetae. Metafemur with setal formula 2-2-1*. Metatibia with AD row with same number of setae as AV row; PD row with approximately twice as many setae as AV and AD rows; PV row with thin and elongated setae close set; all rows without intercalary setae. Metatarsomere I plantar surface with two parallel rows of setae, setae of posterior row larger and with cucullate bases. Male pygofer lobe ( Fig. 4 ) with small rounded inner dorsoapical process. Style ( Figs 6, 7 ) short, with ventral margin expanded preapically, rounded, apex tapered to narrow, sharp point. Aedeagus ( Figs 8-10 ) shaft elongated and tubular; ventral margin cleft; dorsal apodeme without processes. Female sternite VII twice or more wider than long; lateral lobes slightly produced.

Notes. According to DeLong & Freytag (1963), Zonana is related to Dragonana Ball, 1935 because both have punctures on the head, pronotum, and forewings. Based on the generic key by DeLong & Freytag (1972), Zonana differs from Dragonana in lacking fine setae arising from the punctures. However, these fine setae are also present in Zonana specimens herein studied. Nevertheless, Zonana can be distinguished from Dragonana by the following characters: (1) in Zonana the punctures are restricted to the clavus, while in Dragonana they also extend over the corium, except in the apical third; (2) in Dragonana the venation of the apical third of the forewing is reticulate, while reticulate venation is absent in Zonana ; and (3) in Zonana the ventral margin of the style is expanded preapically, rounded, and the apex straight, while in Dragonana the ventral margin is not expanded and the apex is usually strongly curved dorsally.

Distribution. Costa Rica, Panama, Peru, and Venezuela.
