Stegana (Steganina) xanthosticta sp. nov.
( Figures 63–69 View Figures 63–69 )
Diagnosis
Hypandrium with two to three setulae submedially and a few pubescence on flaps ( Figure 66 View Figures 63–69 ); tenth sternite narrowed apically, slightly broadened submedially, and separated basally ( Figure 65 View Figures 63–69 ).
Description
Male terminalia: epandrium slightly protruded ventrally ( Figure 63 View Figures 63–69 ). Surstylus with seven prensisetae submedially ( Figure 64 View Figures 63–69 ). Paramere with ca. five sensilla ( Figures 66, 67 View Figures 63–69 ). Dorsal projection of gonopods rod-like, strongly dorsad protruded in lateral view ( Figure 69 View Figures 63–69 ). Aedeagus without serrated, minute processes ( Figure 69 View Figures 63–69 ).

The body colour pattern is well diversified in this group, as depicted in detail in Table 1. Some body parts show discrete variations of colouration among species, thus
enabling one to distinguish them from one another based on a combination of colourations on different parts.
