Porphyrogenes unassociated unnamed female #2

( Fig. 113, 114 , 165 )

Description. Female ( Fig. 113, 114 ) - forewing length = 24.8 mm, 25.1 mm (from Pará and Rondônia, Brazil); forewing apex pointed, produced, termen slightly convex, anal margin straight; hindwing 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 brown, darkest apically distad of broad pale yellow transverse band originating as elongate opaque macules in costal cell and Sc-R 1, then translucent through discal cell about 2/3 distance from base of wing, base of M 3 -CuA 1, mid-CuA 1 -CuA 2, and terminating near termen as triangular macule in CuA 2 -2A; forewing overscaled with greenish at very base and along middle of anal margin; hindwing unmarked, overscaled with greenish basad in discal cell and posteriorly; inconspicuous erect pale brown tuft along vein 2A; fringes on both wings brown.

Venter similar to dorsum; duller, not as contrastingly dark apically; forewing vein 2A sinuate, shining tan speculum in 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 gray-brown sparsely mixed with greenish, palpi pale gray-brown, eyes reddish, antennae brown, black on club dorsad (including apiculus), yellow on club ventrad, nudum redbrown, 31 (n = 2) segments, ventral thorax gray-brown, pectus greenish, legs ochreous, dorsal abdomen gray-brown, ventral abdomen gray.

Genitalia ( Fig. 165 ) - sterigma more asymmetrical than observed in other Porphyrogenes ; sclerotized caudal portion of lamella postvaginalis with two lobes divided by V-shaped central indentation; lamella antevaginalis with somewhat triangular, asymmetrical, sclerotized central lobe, apex extending to blunt caudal projection; ductus bursae relatively long, broadened cephalad, membranous except for sclerotized lateral plate, joining caudal end of broadly elongate corpus bursae.

Distribution and phenology. This phenotype is known from two specimens: BRAZIL: Pará; Obidos (no date, GTA #14003) and BRAZIL: Rondônia; Vilhena (4 November 1986, GTA #13993) housed at Departamento de Zoologia, Universidade Federal do Paraná, Curitiba, Brazil.

Diagnosis and discussion. This unique phenotype of one of the smaller species of Porphyrogenes combines the brown dorsal coloration of many females of Porphyrogenes with the banded forewing of others. The pale yellow of this diagonal band contrasts with the pure white bands of the four phenotypes of females described immediately above, but is not as intensely yellow as on females of P. omphale .
