Ecliptopera silaceata (Denis et Schiffermüller)

( Figs 11–12 )

The uncus is medium-sized and bent, the socii are absent. The muscles m1 extend from the anterior margin of the tegumen to the base of the uncus. The anal tube is rather broad, with its retractors muscles m2(10) extending from the anterior margin of the tegumen, close to the m3(2), to the distal part of the anal tube. The muscles m3(2) are small, cone-shaped, running from the membrane under the lateral area of the anterior margin of the tegumen to the point of connection of the transtilla to the base of the costa valvae. The medium-sized muscles m4 connect the distal part of the vinculum with the slightly broadened lateral curves of the transtilla. The juxta bears dorso-lateral ovoid labides which are distally connected to the base of the costa valvae by a thin membrane. Distinct rounded lateral cristae are present as well. The labides proximally are sclerotized and stalked. The muscles m8(3) extend from the posterior margin of the saccus to the juxta. The valva is simple, sub-triangular, the muscles m5(7) are reduced in size but not distinctly transverse, being inserted on the ventral margin of the sacculus and the inner wall of the valvae slightly dorsad of the saccular region. The aedeagus is broad, slightly bent, the muscles m6(5) extend from the distal areas of the vinculum, to the basal process of the aedeagus. The muscles m7(6), connect the anterior margin of the saccus with the medial portion of the aedeagus.
