Tegumen moderate. Uncus with dilated base and a rather long sub- 
clavate blunt hook, bristly at the sides. Transtilla, a narrow simple rod, 
sometimes ill-defined or absent. Valva elongate-ovate, simple, disc 
towards base sometimes with an oval field of small round verrucae, 
representing the liarpe. Vinculum elongate, ovate. Anellus with a variably 
shaped furca. Aedoeagus huge, mostly moderately narrowed, little curved. 
C'ornuti, minute denticulations, or absent. 
Ovipositor broad, tortricoid. Ostium modified, variably shaped. Ductus 
bursae often long, coiled, sometimes a dentate cestum present. Signa 
ethmiid: four denticulate plates. 
Key to the Papuan species of Lactura 
1. Longitudinal streaks between veins and along edges of cell mostly crimson 
or orange, sometimes forming a network upon yellow ground colour, often 
traversed by two oblique fasciae usually of darker colour, sometimes brachiate 
and forming a darker network upon above mentioned markings, sometimes 
much dilated so as to form two broad transverse patches or one central patch, 
obscuring crimson interneural network, which still remains distinct, at least 
along dorsum 24 
Markings not thus, mostly simple, sometimes streaks and irregular spots, 
scattered over the wing, but being pale upon darker ground colour, never 
distinctly intemeural, neither forming a distinct crimson or orange network 
upon yellow ground 2 
2. Dark brown with golden gloss; a yellow triangular spot in disc from beyond 
base to middle, traversed by a dark longitudinal streak above middle, erect 
top pointing towards base, lower angle above middle of dorsum

3. Dark purple with a single large transverse orange patch on middle of dorsum 
not reaching costa eurylyca Meyrick

4. Brownish -rosy, margins darker, a transverse yellow band from near base to 
middle, costal edge yellow from this to apex eurycrates Meyrick

5. Dull crimson, apical area from middle of costa to dorsum before tornus enclosing 
two crimson spots, and a light yellow streak along costa . . . callipyra Meyrick
