Genitalia 6 (Fig. 515). Arcessus short with median apical tooth, usually with lateral pro- jections; gonarcus short, broad with lateral projections; gonosaccus short; gonosetae, spinel- lae and gonocristae absent. Genitalia $ (Figs 516-518). Subgenitale often extended and downcurved basally, with basal papilla, mounted on broad, membranous struc- ture; spermatheca short, broad; ventral impres- sion deep; vela very long; duct long, coiled. Remarks. Species of Nodita can be distinguished by their long antennae, the black spot on the stigma, the broadly triangular intramedian cell and the sinuate radial sector. Nodita is very similar externally to Leucochrysa but in Leucochrysa the intramedian cell is quadrangular, Rs is straight, and Rs and the posterior margin of the wing are unmarked. However, these charac- ters are not always reliable and Adams (1977) noted that some species, such as Leucochrysa risi Navas, could be assigned equally well to either group. The male and female genitalia of Nodita and Leucochrysa are almost indistinguishable (see above), but because of the venational differences we have decided to recognize Nodita as a sub- genus of Leucochrysa, rather than as a synonym. Navas (1916) made Nodita available when he described two species in the genus, although he did not include a description of Nodita itself. Instead he merely noted that it was the same as Leucochrysa sensu Banks nee McLachlan. No type species was designated. He later (Navas, 1917) made a formal description of Nodita and designat
