( Figs 196 View Figs 193–196 , 207 View Figs 197–208. 197 , 218 View Figs 209–219 , 257–260 View Figs 257–260 )

Siemssenius tsoui Lee, 2016: 380 (original description).

Type locality. ‘[ Taiwan:] New Taipei city, Hsinhsien’.

Type material examined. Pൺඋൺඍඒඉൾඌ: 1 J ( Figs 257–258 View Figs 257–260 ), ‘ Taiwan: Taipei (22759) / Tsaikungkengshan ([in Chinese]) / 02.V.2012, leg. S.- F. Yu [w, p] // Paratypus / Siemssenius / tsoui sp. nov. [p] J [h] / des. C.-F. Lee, 2016 [pink label, p]’ ( JBCB); 1 ♀ ( Figs 259–260 View Figs 257–260 ), ‘ Taiwan: Taipei / Erhtzuping ([in Chinese]) / 29.IV.2016, leg. C.-F. Lee [w, p] // Paratypus / Siemssenius / tsoui sp. nov. [p] ♀ [h] / des. C.-F. Lee, 2016 [pink label, p]’ ( JBCB).

Diagnosis. Colouration. Body black, except for reddish brown elytra and abdomen.

Body length. J: 10.0 mm, ♀: 11.1 mm.

Male ( Fig. 257 View Figs 257–260 ). Antennae 0.95 times as long as body. Pronotum convex, 1.71 times as wide as long, very finely punctate, anterior margin nearly straight, unbordered, posterior margin moderately rounded, thinly bordered, lateral margins slightly convergent in posterior two thirds, anterior third rounded and more distinctly convergent, with wider border. Protarsomere I elongate, subtriangular. Metatibial spur short, robust, subtubular, with transversely cut apex. Aedeagus ( Fig. 196 View Figs 193–196 ). Median lobe of aedeagus 3.68 times as long as wide, with apical process narrow, separated from lateral elevations by V-shaped incisions, rest of median lobe subparallel. Lateral view: median lobe bisinuate, very narrow in middle part; lateral elevation quadrangular, placed in anterior fifth of aedeagus length. Dorsal process 5.31 times as long as wide, 0.83 times as long as median lobe, lanceolate. Lateral view: dorsal process widely regularly rounded, apical half slightly wider, apex sharp. Female ( Fig. 259 View Figs 257–260 ). Antennae shorter, 0.75 times as long as body. Protarsomeres narrower than in males. Metatibial spur short, narrow, with moderately rounded apex. Sternite VIII heart-shaped, posterior margin rounded with shallow emargination in middle, surface laterally with two elevated plates, long setae accumulated along posterior and inner margins of those plates, tignum short, 0.30 times as long as sternite VIII, slightly asymmetrical to right ( Fig. 218 View Figs 209–219 ). Spermatheca with poorly developed nodulus, cornu C-shaped, spermathecal duct slightly bent ( Fig. 207 View Figs 197–208. 197 ).

Differential diagnosis. Having black body and reddish brown elytra and abdomen, Liroetis tsoui is very similar to other Taiwanese species L. jungchani , L. liui , L. rufipennis , and L. yuae . These species can be reliably identified only based on the structure of aedeagus ( Figs 189–190 View Figs 189–192 , 194, 196–197 View Figs 193–196 View Figs 197–208. 197 ). Median lobe of aedeagus of L. tsoui has apical process extremely short, lateral elevation large, quadrangular, dorsal process moderately lanceolate and in lateral view distictly extended subapically ( Fig. 196 View Figs 193–196 ).
