AEDEAGUS (Fig. 5A‒C). Strongly swollen laterally in basal part, contracted in diameter apically; basal piece nearly as long as dorsal plate of each paramere, with a large, bifurcate conjoint middle nodule at base of ventral side; ventral processes of parameres nearly parallel to one another, distinctly thickened apically, bent dorsally in lateral view; dorsal plate slightly longer than ventral process, abruptly narrowed in middle and wide-triangularly protuberant at apical part, near to each other at basal part, apex acute and folded ventrally; apical parts of laterophyses depressed and separate from each other, apex acute and bent dorsally, reaching middle emargination between dorsal plates.
