groups (regular rows or with one row irregular) of small setae on plantar sur- 
face. 
Male pygofer weakly produced, with posterior margin usually very broadly 
rounded, with numerous macrosetae (macrosetae and microsetae in O. hebeta, 
n. sp. and O. partitula (Jacobi)) distributed over most of surface except basi- 
dorsally, or limited to apical one-half, pygofer processes absent (exception: 
partitula). Plates separate throughout their length, their posterior extent 
variable interspecifically with relation to apex of pygofer, each triangular, with 
arrangement of macrosetae usually uniseriate. Style extending posteriorly to a 
variable distance compared with apex of connective, with or without pre- 
apical lobe, apex varying interspecifically. Connective Y-shaped. Aedeagus 
very variable interspecifically, but usually with conspicuous basidorsal and 
basiventral apodemes. Paraphyses present or absent. 
Female (unknown in many of the species) abdominal sternum VII with 
posterior margin transverse or moderately produced posteriorly and acute or 
slightly concave at apex. Genital chamber with or without one or more 
sclerites. Ovipositor with second valvula broadened throughout portion 
beyond basal curvature and bearing primary teeth on dorsal margin, each of 
which bears minute secondary denticles, apex acute, with anteapical dorsal 
and ventral denticles. Pygofer narrowly rounded posterodorsally, with a num- 
ber of irregularly arranged macrosetae in a diagonal group parallel to postero- 
ventral pygofer margin. 
Specimens of Oragua Melichar are opaque black or fuscous, often with paler 
markings in the form of spots, marked with orange spots in some species. 
Specimens belonging to Oragua have been examined from Southern Mexico, 
Guatemala, Honduras, El Salvador, the Guianas, northern, central, and 
southern Brazil, Ecuador, Peru, Bolivia, and Argentina. Nothing is known of 
the biology of the species.

Oragua Melichar belongs to a group of genera that I have not been able to 
characterize because of species diversity within several of the genera. The 
complex includes Acrulogonia, Tubiga, Selvitsa, Scoposcartula, Schildola, and 
Trachygonalia, all described below. Of these, Oragua is most similar to
