Description. Aedeagus concave and wide, sides subparallel; apico-lateral angles obtusely angulate, wide in lateral view, bases of apico-lateral angles moderately arcuate; apical margin with a short and narrow median tubelike process, wide in lateral view, apex slightly and medially depressed; dorsal process subapically and strongly swollen in dorsal and lateral views, apex recurved and pointed in lateral view (Figs 8 A–8B). Ventrite V (Fig. 8 D) not modified in female, apical margin broadly rounded. Gonocoxae reduced. Ventrite VIII (Fig. 8 E) heart-shaped, with extremely short spiculum, with dense elongate setae along apical margins of triangulate processes. Tergite VIII (Fig. 8 G) with apex pointed, with dense setae on disc. Receptacle of spermatheca (Fig. 8 H) weakly swollen, barely separated from pump, pump much narrower and longer, sharply curved; proximal spermathecal duct long and narrow.
Variation. Females collected from Pilu, east Taiwan, have the sinuate apical margin of abdominal ventrite V (Fig. 8 C) bearing sparse elongate setae along apical margins of triangulate processes on ventrite VIII (Fig. 8 F).
Diagnosis. Siemssenius liui sp. nov. is characterized by the extremely short, tube-like median process on the apical margin of the aedeagus (Figs 8 A–8B).
Remarks. Eight paratypes of Pseudoliroetis rufipennis Chûjô are misidentified and belong to this new species.
Host plant. Lonicera acuminata Wall., 1832 (Caprifoliaceae).
Etymology. This new species is named after Mr. Wei-Ting Liu, a member of the TCRT and first to collect this new species.
Distribution. Montane areas in north and east Taiwan (Hualien, Ilan, and Taoyuan counties) (Fig. 4).
