Porphyrogenes glavia Evans, 1952

( Fig. 33, 34 )

Porphyrogenes glavia Evans, 1952 . Type locality: Panama; male [holo] type ( Fig. 33, 34 ), in BM(NH).

Description. Male (measured and described from photographs of the [holo] type, Fig. 33, 34 ) - forewing length = 19.6 mm; forewing with no apparent costal fold, apex rounded, termen convex, anal margin slightly convex; hindwing termen convex, tornus produced to very short lobe, vein Rs arising nearer to end of discal cell than to its base and distad of CuA 2; dorsum brown (purplish gloss noted by Evans 1952 not evident in photograph), unmarked; no overscaling evident, no apparent tuft; hindwing with shining grayish brown speculum in proximal 1/3 of costal cell; no tufts evident; fringes on both wings pale brown.

Venter duller brown than dorsum with purplish wash; forewing veins CuA 1, CuA 2, and 2A strongly bowed, otherwise vein 2A appears unmodified; shining gray-brown speculum in proximal 1/4 of CuA 2 -2A and apparently modified gray-brown scales in proximal 1/2 of anal cell; hindwing with no indication of discal macules; cell 2A-3A with groove proximad just caudad of vein 2A.

Dorsal head and thorax appearing dark brown, palpi brown with 3rd segment upcurved and extended far beyond 2nd segment (a character not on other Porphyrogenes ), eyes red, antennae black on dorsum, whitish on venter and beneath apiculus; ventral thorax apparently brownish, legs missing; abdomen brownish.

Genitalia - not examined. Evans’ (1952) figure indicated a broad valva cephalad with the spiculose caudal end of the harpe very narrow and directed dorsad.

Female - not examined.

Distribution. The type is from Panama and the associated female has no location indicated ( Evans 1952); these are the only known specimens of this species.

Diagnosis and discussion. The female of P. glavia was described as being brown on the dorsum with a purple flush and a bright ochreous hindwing, yellow-brown on the venter, and without macules on the forewing ( Evans 1952); this specimen was not examined for this study. This species was named from a pair of specimens; the male in the BM(NH) is the [holo] type ( Fig. 33, 34 ). Porphyrogenes glavia cannot be confused with any other species of Porphyrogenes .
