behind transverse sulcus. Forewing with membrane sharply delimited, in- 
cluding apical cells in their entirety, or in part (varying intraspecifically), 
veins very indistinct except in teneral specimens, with three closed anteapical 
cells of which the bases are all proximal to a transverse line through claval 
apex, with four apical cells, the base of fourth more proximal than base of 
third, without an anteapical plexus of veins; forewing of female in rest posi- 
tion exceeding apex of ovipositor. Hindleg with femoral setal formula 2:1:1; 
length of first tarsomere greater than combined length of two more distal tar- 
someres, and with two parallel rows of small setae on plantar surface. 
Male genitalia: Pygofer strongly produced, apex varying from subangulate 
to broadly convex, with macrosetae on apical one-half or one-third, not aris- 
ing in area parallel to ventral margin, pygofer processes differentially 
sclerotized, arising anteapically on mesal surface of pygofer, extending mesad 
across median line in some specimens. Plates elongate triangular, extending 
posteriorly approximately as far as pygofer apex, each with uniseriate 
macrosetae. Style extending posteriorly farther than apex of connective, 
narrowed and curved posterolaterally in its apical portion, narrowly rounded 
apically, without a distinct preapical lobe. Connective broadly Y-shaped, or 
U-shaped. Aedeagus with shaft broad and bisinuate, broadly rounded 
apically, with an unpaired basal sclerite which appears as a distinct ventral 
aedeagal process (V. ruficauda (Walker)) or as a paraphysis. 
Female abdominal sternum VII truncate or regularly concave at apex. Dor- 
sal membrane of genital chamber with or without a pair of sclerites. 
Ovipositor with second valvulae each not expanded near base, of nearly uni- 
form width throughout length except at apex, with poorly developed primary 
teeth in apical one-third or one-half, the primaries bearing minute denticles, 
with numerous dorsal anteapical denticles, apex narrowly rounded, without a 
ventral anteapical angle. Pygofer with multiseriate macrosetae in a vertical 
group along posterior and posteroventral margin. 
Specimens belonging to Versigonalia have been examined from southern 
Brazil and northern Argentina. Externally, the species of Versigonalia are very 
similar to those of Macugonalia, but the male plates are much longer and the 
abdominal sternum VII of the female is not produced in Versigonalia. The in- 
ternal male genitalia of Verstgonalia include a paraphysis which is lacking in 
Macugonalia, and the shape of the shaft of the aedeagus is quite different in the 
two genera. 
Nothing is known of the biology of species of Versigonalta.
