Liroetis jungchani (Lee, 2016) comb. nov.

( Figs 189 View Figs 189–192 , 201 View Figs 197–208. 197 , 212 View Figs 209–219 , 220–223 View Figs 220–223 )

Siemssenius jungchani Lee, 2016: 375 (original description).

Type locality. ‘[ Taiwan:] Pingtung county, Tahanshan’.

Type material examined. Pൺඋൺඍඒඉൾ: 1 J ( Figs 220–223 View Figs 220–223 ), ‘ Taiwan: Pingtung / Tahanshan ([in Chinese]) / 31.III.2012, leg. W.-C. Liao [w, p] // Paratypus / Siemssenius [p] J [h] / jungchani sp. nov. / des. C.-F. Lee, 2016 [pink label, p]’ ( JBCB).

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

Body length. J: 10.4 mm.

Male ( Figs 220–223 View Figs 220–223 ). Antennae 0.95 times as long as body. Pronotum convex, 1.65 times as wide as long, finely punctate, anterior margin slightly concave, with thin border visible laterally and disappearing in middle part, posterior margin straight in middle part, oblique and with two points laterally, thinly bordered, lateral margins straight and parallel in posterior two thirds, anterior third rounded and convergent, with wider border. Scutellum with several distinct punctures. Protarsomere I elongate subtriangular. Metatibial spur short, wide, with rounded apex.

Aedeagus ( Fig. 189 View Figs 189–192 ). Median lobe of aedeagus 5.43 times as long as wide, with apical process short, narrow and parallel, then suddenly widened, rest of median lobe almost parallel. Lateral view: median lobe bisinuate in middle part, apical part slightly bent; lateral elevation large, widely subtriangular, placed in anterior fifth of aedeagus length. Dorsal process 7.11 times as long as wide, 0.79 times as long as median lobe, lanceolate, with sharp apex. Lateral view: dorsal process slightly regularly rounded, slightly wider subapically, apex sharp.

Female. Sternite VIII subpentagonal, posterior margin shallowly concave, surface laterally with two elevated plates, long setae accumulated along posterior and inner margins of those plates, tignum short, 0.20 times as long as sternite VIII ( Fig. 212 View Figs 209–219 ). Spermatheca with well developed nodulus, cornu C-shaped, spermathecal duct bent ( Fig. 201 View Figs 197–208. 197 ).

Differential diagnosis. Having black body and reddish brown elytra and abdomen, Liroetis jungchani is very similar to other Taiwanese species L. liui , L. rufipennis , L. tsoui , 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. jungchani has lateral elevation large, widely subtriangular, dorsal process narrowly lanceolate and in lateral view only slightly extended subapically ( Fig. 189 View Figs 189–192 ).
