 Porphyrogenes boliva Evans, 1952. Type locality: Venezuela; male [holo] type (Fig. 1, 2) in BM(NH).   
 Description. Male (Fig. 1, 2, 51, 52) - mean forewing length = 23.7 mm (23.1-24.5 mm, n = 5; from Rondônia, Brazil); forewing with costal fold, apex slightly produced, slightly rounded, termen relatively straight, anal margin straight; hindwing termen nearly straight, tornus produced to short lobe, vein Rs arising mid-base and end of discal cell and basad of CuA 2 (Fig. 115); dorsum brown, unmarked; forewing overscaled with tawny-ochreous, heaviest basad, anal margin with very sparse tuft proximad; hindwing overscaled with tawny-ochreous posterior to vein Rs, vague indication of brown discal macules on some individuals; shining gray-brown speculum in anterior base of discal cell, proximal 1/4 of Sc+R 1 -Rs, and proximal 1/2 of costal cell; short and sparse ochreous-tan recumbent tuft near base of Sc+R 1 -Rs covering speculum in Sc+R 1 -Rs, similar semierect ochreous-tan tuft arising from near base of discal cell covering speculum in discal cell (Fig. 115); conspicuous erect ochreous tuft along anterior edge of vein 2A, recumbent pale yellow-tan tuft from posterior edge of 2A; fringes on both wings dark brown.   
 Venter similar to dorsum; tawny color duller; forewing vein 2A unmodified, nearly straight (Fig. 115); recumbent tuft anterior to central 1/3 of this vein, tan basad, brown distad; shining gray-tan speculum in proximal 1/4 of CuA 2 -2A and in proximal 1/3 of anal cell (continued to tornus as modified tan grading to brown scales); hindwing with vague indication of dark discal macules; relatively conspicuous brown area at tornus; cell 2A-3A with shallow groove just caudad of 2A.   
Dorsal head and thorax tawny-ochreous, palpi ochreous-tan, eyes red, antennae black, yellow on distal 2/3 of venter and beneath apiculus, nudum red-brown, 27 (n = 2), 28 (n = 1), or 29 (n = 2) segments, ventral thorax tawny-ochreous, pectus ochreous-tan, legs orange, dorsal abdomen dark brown, pale brown or gray at segments, overscaled with tawny-ochreous especially anteriorly, ventral abdomen paler tawnyochreous to gray-brown.  
Genitalia (Fig. 134) - tegumen broad and quadrate in lateral and dorsal views, short dorso-caudal oriented process from each side of caudal end, tuft double and very sparse; uncus decurved in lateral view, divided in V-shape in dorsal view, arms moderately spaced caudad, long and broad, ventral process of uncus triangular; gnathos shorter than uncus, terminal ends rounded in ventral view; combined ventral arms from tegumen and dorsal arms from saccus curved; saccus narrow and long, oriented cephalad; valva with costa-ampulla broadly rounded, curving ventro-caudad to harpe, harpe moderately long, narrow, curving evenly upward to blunt and spiculose caudal end oriented nearly dorsad; aedeagus about length of valva, broad with blunt caudal end; cornuti as several (at least three) clusters of long and thin spikes.  
Female - unknown.  
 Distribution and phenology. Porphyrogenes boliva was known from two males from Venezuela (Evans 1952). The records from Rondônia, extending this distribution far southward, are for June (1), August (1), October (2), and December (1).   
 Diagnosis and discussion. Evans (1952) based his description of P. boliva on two males from Venezuela. One of these (Fig. 1, 2) is the [holo] type. This species tends to be paler tawny on the dorsum than its congeners. Evans’ (1952) drawing of the genitalia of P. boliva indicates a much longer harpe than on males from Rondônia, an error also noted for some of his other representations of the genitalia of Porphyrogenes (see P. pausias and P. probus below).
