Papp, L.: New species of Lygistorrhinidae (Diptera) from the Oriental Region

Abdomen very thin and much longer than wing, tergites all dark. Tergite 8 (Fig. 17) comparatively long with a large medio-caudal process. This process may be slightly different from that one on our figure (the process is half of a cone, i.e. may be depressed at a different extent), but microtrichia cover all part, in contrast to M. similis. Sternite 8 as in M. similis. Tergite 9 (Figs 18-19) broad and slightly longer than gonocoxites, its macrosetae slightly longer, than in M. similis. Gonostylus (Fig. 20) shorter than gonocoxite, its apical tooth comparatively short, broad and rounded. Gonocoxites without any conspicuous armature, but with a twice, angularly bent narrow medial process (Fig. 21 ). The pair of medial processes (placed most dorsal under T9), and ventral wall of gonocoxites form a "tunnel", in which aedeagal complex moves forward and backward along the body axis. Aedeagus mostly membranous and protected by a scutiform "shield" (I would rather not decide on its morphological - homology - status). Aedeagal apodeme small, joins ventral wall of the "shield". Female is still unknown. * Acknowledgements - Specimens from Taiwan were collected during a collection trip sponsored by the National Science Council, Taipei.
