more proximal than base of third, otherwise as in Newa; hindwing greatly 
reduced in size but with vein R,,3 entire. Hindleg with intercalary setae between 
large setae of tibial row 2; length of first tarsomere approximately equal to com- 
bined length of two more distal tarsomeres; otherwise as in JVeiva. 
Male genitalia: Pygofer strongly produced and narrowed apically, with 
numerous mixed macro- and microsetae on posterior half and ventrally near 
base; ventral margin with numerous close-set microsetae on apical portion. 
Plates triangular, not extending posteriorly nearly as far as pygofer apex, with 
uniseriate macrosetae along lateral margin almost to apex and with apical multi- 
seriate microsetae. Style very short, not extending posteriorly much beyond apex 
of connective, without a distinct preapical lobe. Connective very short, somewhat 
Y-shaped, without a median keel. Aedeagus symmetrical, elongate, slender, 
gradually tapered in apical half to expanded apex, without processes. 
Paraphyses absent. 
Female abdominal sternum VII with posterior margin not strongly produced, 
with a weak rounded lobe on each side of broad median slightly convex portion. 
Genital chamber with dorsal membrane lacking sclerotization. Ovipositor with 
second valvula broad beyond basal curvature, its ventral margin not convex, with 
somewhat convex primary teeth on dorsal margin, each with minute second- 
aries, with a number of anteapical minute teeth on dorsal and apicoventral 
margins, apex acute. Pygofer with a narrow group of setae parallel to posterior 
margin. 
The genus Ortega Melichar is closer to Aguana Melichar than to the other 
genera discussed in the above treatment of Neva Melichar, in lacking an an- 
teapical plexus in the forewing, and in having macrosetae on the male plates. It 
differs from all of the other genera in the Vewa group in not having paraphyses in 
the males. 
Three specimens of the type-species, one male each in NMV and BM 
(holotype) and one female (NCS) have been seen by the writer, all from Colom- 
bia. 
The restoration of the secondary homonym obdliqua (Walker) for the type- 
species of Ortega, in the Metcalf catalogue (1965:604), an action taken before the 
present rules were available, doesn’t conform to Article 59(c) of the International 
Rules and is therefore not followed here.
