Eulithis populata (Linnaeus)

( Figs 13–14 )

The musculature of this species is shown in Razowskj and Wojtusiak (1981).

The uncus is medium-sized, the socii are absent. The muscles m1 extend from the lateral corners of the anterior margin of the tegumen to the base of the uncus. The muscles m2(10) are attached near the muscles m1 and run towards the distal area of the broad anal tube where they are inserted close to the tip of the double-striped subscaphium. The muscles m3(2) run directly from the anterior margin of the tegumen to a not prominent basal process of the costa valvae close to the transtilla. The fan-shaped muscles m4 connect the vinculum to the lateral rounded curves of the transtilla. The juxta is slightly broader than long, with the labides bearing clubbed setae, set rather dorsally. The muscles m8(3) extend from the posterior margin of a large, almost hemispherical saccus to the posterior margin of the juxta. The valva is simple, the muscles m5(7) are very small, inserted near the basal angle of the sacculus and run towards the dorsal margin of the sacculus. The aedeagus is rather short and broad, with the muscles m6(5) extending 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.

Remarks. The genital musculature of Eulithis mellinata (Fabricius, 1787) was illustrated by Valersky (2011).
