Calyptoproctina

SUPPLEMENTAL KEY TO THE GENERA OF “ CALYPTOPROCTINA ” OCCURRING NORTH OF PANAMA

Poiocerini genera where females may have supra-anal plates; here including Hypaepa, (number in parentheses indicates the number of species in Mesoamerica only).

1. Frons much shorter than broad and distinctly broadest above (Fig. 99)........................................... 2

-. Frons broadest below, or medially, or parallel-sided.......................................................... 3

2. Fore femora strongly flattened, apically foliose, with lamellate forecoxae; forewings narrowed, costal margin nearly straight; vertex flat........................................................... Cyrpoptus Stål (Panama to U.S.; 11 spp.)

-. Fore femora not flattened, forecoxae not lamellate; forewings normal, costal margin evenly convex; vertex with median pit............................................................. Calyptoproctus Spinola (Brazil to Mexico; 3 spp.)

3. Vertex almost flat, bordered anteriorly by a low carina, with posterior corners slightly enlarged and angled upwards above eyes (Fig. 101); frons unmarked and coarsely vermiculate-rugose; upper posterior edge of mesocoxa with large, prominent tubercle, almost as large as that on metacoxa; fore- and hindwings with apical half pigmented; forefemoral apices with well-defined setose ridges (2 complete dorsal ridges, 2 complete ventral ridges, the latter defining a shallow groove against which the tibia rests)......................................... Jamaicastes Kirkaldy (Antilles, possibly Ecuador & Bolivia; 2 spp.)

-. Vertex concave, bordered by carina that is distinctly elevated anteriorly, with posterior corners appressed to inner posterior margin of eyes; frons variable; upper posterior edge of mesocoxa with at most a small, acute tubercle; forewing with apical half mostly or entirely clear or stained hyaline other than occasional irregular maculations, hindwing apically clear hyaline; femoral apices with at most two or three well-defined ridges (typically 1 anterodorsal, 1 anteroventral, no definite ventral groove).. 4

4. Eyes protruding laterally and dorsally; frons widest medially or just below middle; terminal antennomere nearly half as large as eyes (Fig. 100)................................................... Hypaepa Stål (Brazil to Guatemala; 4 spp.)

-. Eyes fairly closely appressed to anterior prothorax; frons nearly parallel-sided, widest below at clypeal juncture; terminal antennomere much smaller than eyes...................................................................... 5

5. Terminal antennomere small, almost spherical or pyriform, diameter subequal to antennal socket; thoracic dorsum typically with numerous fine erect setae; femora with contrasting bands; hindwings with basal membrane often orange to red (if blue, then with very little black); clypeus typically at least 1.5 times as long as broad and almost straight on sides (Fig. 104); male gonostyli distinctly incurved apico-dorsally for nearly half their length....... Scaralina gen. nov. (Panama to U.S.; 15 spp.)

-. Terminal antennomere weakly to strongly asymmetrically ovoid, diameter clearly exceeding antennal socket; dorsum with or without obvious short setae; femora without contrasting bands; hindwings with basal membrane with considerable black, and usually also blue; clypeus distinctly less than 1.5 times as long as broad, and somewhat constricted laterally; male gonostyli open dorsally and converging at apex..................................................................... 6

6. Head and thorax uniformly greenish in coloration; dorsum and pleura with numerous short setae (Fig. 102); forewings with apical cellules very small and crowded, also greatly elongated and narrow, often well over 5x longer than broad....................................................................... Matacosa Distant (Colombia to Costa Rica; 1 sp.)

-. Head and thorax heavily patterned with contrasting markings (Figs 95–96, 103); dorsum bare or with few, short, scattered setae; forewings with apical cellules square to rectangular, 4x longer than broad or less................................... 7

7. Forewing broad with apices rather oblique; nodal line strongly arcuate and impressed; vertex much broader than wide, especially relative to eyes; male gonostylar hooks somewhat distorted, blunt at tip (Fig. 9) and anal tube widest near middle with narrow aperture (Fig. 10); large species (forewings> 18 mm).................. Scaralis (Scaralis) Stål (Brazil to Mexico; 2 spp.)

-. Forewing narrow with apices more rounded (Figs 72, 95); little or no impressed nodal line; vertex narrower than preceding, especially relative to eyes (Figs 95–96); male gonostylar hooks sharply acute at tip (Fig. 93) and anal tube widest near apex with broad aperture (Fig. 11); small species (forewings <16 mm)................................................................................................ Scaralis (Alphinoides) subgen. nov. (Brazil to Guatemala; 1 sp.)
