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) - fore-  
wing 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 CuA2; 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 CuA1, CuA2, and 2A strongly  
bowed, otherwise vein 2A appears unmodified; shining gray-brown speculum in proximal 1/4 of CuA2-2A  
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.
