three-tenths to slightly less than four-tenths transocular width, anterior 
margin broadly rounded in dorsal view, without a carina at transition from 
crown to face, ocelli located on or slightly before a line between anterior eye 
angles, each slightly closer to adjacent anterior eye angle than to median line 
of crown, crown with middle of disk convex or very slightly concave medially, 
lateral clypeal sutures extending onto crown and attaining ocelli; antennal 
ledges not protuberant in dorsal view, in lateral view with anterior margins 
vertical and rectilinear, clypeus slightly flattened medially, muscle im- 
pressions distinct or not, transclypeal suture obscure medially, clypellus with 
profile of its lower portion slightly more nearly horizontal than remainder of 
contour of face. 
Thorax with pronotal width equal to or less than transocular width of head, 
lateral margins parallel or slightly convergent, dorsopleural carinae complete, 
posterior margin slightly concave, disk without sculpturing; scutellum not 
transversely rugose behind transverse sulcus. Forewing with membrane ab- 
sent or limited to inner apical cell or to inner two apical cells, with four apical 
cells, the base of fourth more proximal than base of third, without an ante- 
apical plexus of veins, texture translucent to opaque. Hindleg with femoral 
setal formula 2:1:1 or 2:1:1:1; length of first tarsomere greater than com- 
bined length of two more distal tarsomeres and with two parallel rows of 
small setae on plantar surface. 
Male genitalia: Pygofer scarcely to moderately produced with a postero- 
dorsal process varying interspecifically in position from anteapical to apical, 
and with an additional process (also varying interspecifically) in some species, 
macrosetae varying from two to approximately twenty, limited to apical half 
of pygofer. Plates varying interspecifically in extent relative to pygofer apex, in 
shape, and in chaetotaxy. Style extending posteriorly beyond apex of con- 
nective (exception: A. reclusa, n. sp.), with or without preapical lobe. Con- 
nective variable interspecifically. Aedeagus symmetrical, shaft elongate, apex 
abruptly curved at a right angle to long axis of shaft (exception: reclusa), shaft 
usually with at least one pair of processes. Paraphyses absent. 
Female abdominal sternum VII slightly produced and gradually narrowed 
to a bluntly convex or a shallowly concave apical margin. Genital chamber 
with sclerites in dorsal membrane or with dorsal wall entirely sclerotized. Ovi- 
positor with broad, toothed area of each second valvula occurring through 
most of length except curved basal portion, the primaries sloping, regular, and 
with numerous secondary denticles, apex narrowly rounded, with anteapical 
posterodorsal and posteroventral denticles. 
Species of Acrulogonia, new genus, are pale to dark brown, sprinkled with 
pale dots and small spots and occasionally with pale vermiculations, and in 
some species with pale to orange larger spots on the forewings. The forewings 
are translucent and often with dark red veins. 
The range of Acrulogonia is from Panama, Venezuela, and Colombia to the 
Guianas, and northeastern Brazil and Peru and Bolivia. Acrulogonia belongs to 
the Oragua Melichar complex of genera, and is probably more closely related 
to Oragua than to other genera in the complex. For distinguishing characters, 
see the discussion of Oragua.
