Porphyrogenes unassociated unnamed female #5

( Fig. 111, 112 , 164 )

Description. Female ( Fig. 111, 112 ) - forewing length = 28.0 mm (n = 1; from Costa Rica); forewing apex produced, pointed, termen convex especially apically, anal margin slightly concave; hindwing termen convex except concave just before prominent tornal lobe, vein Rs arising nearer to end of discal cell than to its base and distad of CuA 2; dorsum brown with bluish sheen; forewing overscaled with gray-brown basad, white translucent macules, one small and triangular in M 3 -CuA 1, base on vein CuA 1, more than half distance from its origin to termen, other very large and more or less parallelogram-shaped in CuA 1 - CuA 2, centered under origin of CuA 1; hindwing unmarked, overscaled with gray-brown posterior to vein Rs, no indication of discal macules; conspicuous erect gray-brown tuft on dorsum of vein 2A; fringes on both wings pale gray-brown.

Venter dull brown; forewing overscaled with gray basad, forewing vein 2A slightly curved, entire anal cell with modified pale tan scales; hindwing overscaled with gray, no indication of discal macules; cell 2A- 3A with groove just caudad of vein 2A.

Dorsal head (including palpi) and thorax pale brown, eyes appear brown, antennae black on dorsum, yellowish on venter especially distad, nudum red-brown 31 (n = 1) segments, ventral palpi tan, ventral thorax and pectus pale brown, legs pale brown proximad, dull ochreous distad, dorsal and ventral abdomen gray-brown.

Genitalia ( Fig. 164 ) - lamella postvaginalis sclerotized caudad, caudal edge curved with narrow and shallow U-shaped indentation centrally, this is followed cephalad by pair of oval sclerotized areas; lamella antevaginalis as rectangular sclerotized central plate and membranous plates laterad; ductus bursae elongate, moderately broad, and membranous with elongate sclerotized plate cephalad, joining globular corpus bursae cephalad of its caudal end.

Distribution and phenology. One individual was examined: COSTA RICA: Ciudad Colon, Finca Hamadryas, 900 m, 9°54’N, 84°17.5”W, 20 April 1998 (GTA #13921, housed at Mississippi State University).

Diagnosis and discussion. This is similar to the previous two phenotypes and perhaps intermediate in size. It is the fourth female of Porphyrogenes known from southern Central America (including the undescribed species noted above) with gray-brown wings and at least one large white macule on the forewing. The three described here have a second and smaller white macule on the forewing that is absent on all twelve females of the unnamed species illustrated by Janzen and Hallwachs (2008). That species also differs by its prominently white fringes. Including these three, there are now five (also including P. virgatus and P. eudemus ) unplaced female phenotypes of Porphyrogenes known from Central America. Males known from Central America without associated females include P. zohra , P. sula , P. spoda , and P. spina . Undoubtedly, females for at least some of these are among the pool of females detailed above.
