Chloroclysta siterata (Hufnagel)

( Figs 3–4 )

The uncus is long and thin, broadened at base, with very small, rounded, lateral outgrowths. The medium-sized muscles m1 extend from the anterior margin of the high and narrow tegumen to the base of the uncus. The muscles m2(10) connect the medio-lateral portions of the anterior margin of the tegumen with the distal area of the anal tube, which bears a subscaphium formed by two longitudinal weakly sclerotized stripes joined together distally. The muscles m3(2) run from the small lateral projections of the anterior margin of the tegumen to the apices of the short projections at the base of the costa valvae. The muscles m4 extend from the proximal rounded outgrowths of the vinculum to the projections at the base of the costa valvae, with very thin filaments attached to the most lateral part of the transtilla, close to the base of the costa valvae. The valva is large, narrowest at the base, the muscles m5(7) are very small, connecting the ventral and dorsal margins of the sacculus. The juxta bears conspicuous dorso-lateral labides crowned with long thick setae. The muscles m8(3) run from the posterior margin of a very shallow saccus to the area between the bases of the labides. The aedeagus is relatively small, with a patch of thin cornuti, the muscles m6(5) connect the distal parts of the vinculum with the basal process of the aedeagus. The muscles m7(6) run from the anterior margin of the saccus to the medio-proximal area of the aedeagus.
