Porphyrogenes unassociated unnamed female #1

( Fig. 105, 106 , 163 )

Description. Female ( Fig. 105, 106 ) - forewing length = 28.6 mm (n = 1; from Ecuador); forewing apex slightly rounded, not produced, termen convex, anal margin straight; hindwing slightly convex, tornus produced to very short lobe, vein Rs arising nearer to end of discal cell than to its base and well distad of origin of CuA 2; dorsum dark brown with slight purplish sheen; forewing overscaled basad with dull blue-green, continuous very narrow white band from costa (where divided into two thin elongate macules), through distal end of discal cell, base of M 3 -CuA 1, mid-CuA 1 -CuA 2, and terminating nearly at termen distad in CuA 2 -2A; hindwing overscaled with blue-green basad, largely posterior of discal cell, more extensive than on forewing, extending to 2/3 distance to termen at tornus; inconspicuous erect brown (with blue-green proximad) tuft along vein 2A; fringes on both wings brown.

Venter similar to dorsum; duller; forewing vein 2A weakly sinuate, shining gray speculum in proximal 1/4 of CuA 2 -2A and entire anal cell; hindwing with no indication of discal macules; cell 2A-3A with deep groove just caudad of vein 2A.

Dorsal head and thorax brown, overscaled heavily with blue-green, palpi gray with bluish tint, eyes dull reddish, antennae black, yellow-orange on venter of club, nudum red-brown, 33 (n = 1) segments, ventral thorax dark gray with some bluish scales, pectus blue-gray, legs dull ochreous, dorsal abdomen dark brown, ventral abdomen dark gray-brown.

Genitalia ( Fig. 163 ) - lamella postvaginalis sclerotized, caudal edge slightly angulate towards narrow and shallow U-shaped indentation centrally; lamella antevaginalis with two sclerotized lobes converging, broadening, angling caudad centrally; ductus bursae long, relatively broad, and entirely membranous, joining corpus bursae at its caudal end; corpus bursae bulbous.

Distribution and phenology. A single female (GTA #13986) of this phenotype was examined from Ecuador (Yasuni National Park, Yasuni Field Station, 767’) taken on 8 May 2003 and currently in the collection of A. D. Warren.

Diagnosis and discussion. This phenotype, with its dark color and diagonal white band on the forewing, is generally similar to the three preceding species. The termen of the forewing is not as strongly convex as that of P. passalus , but not nearly straight as on P. virgatus and P. eudemus . The apex of the forewing is not highly angular as on P. virgatus . Vein 2A on the forewing is slightly sinuate and not as strongly as on P. passalus or strongly bowed as on P. virgatus . The white band is much narrower than on P. passalus and P. eudemus , but not quite as narrow as on P. virgatus . The tornal lobe on the hindwing is barely perceptible in contrast with the more prominent lobe on P. virgatus and P. eudemus . The genitalia of this female differ notably from that of the female considered here to be P. eudemus .
