Liroetis prominensis Jiang, 1988

( Figs 113 View Figs 108–117 , 132–139 View Figs 132–139 )

Liroetis prominensis Jiang, 1988: 187 , 196 (original description).

Liroetis prominensis : Bൾൾඇൾඇ (2010):478 (catalogue);YൺඇǤ et al. (2015): 247 (key), 249 (noted).

Type locality. ‘[ China:] Sichuan: Mt. Emei’.

Type material examined. Pൺඋൺඍඒඉൾඌ: 1 J ( Figs 137–139 View Figs 132–139 ), ‘[Sichuan, Mt.Emei, 2100 m / 1955.VI.24 / Buxike] [in Chinese, w, combined p and h] // Oмейшань, 2100 м. / Сычуань 24 У1 1955 / Бущик [in Russian, w, combined p and h] // PARATYPE [y, p] // [No. 16] [in Chinese, w, h] // IOZ(E)1967850 [w, p] // Liroetis / prominensis Jiang 1988 / Det. Jiang Shengqiao [w, p]’ ( IZAS); 1 J ( Figs 132–136 View Figs 132–139 ), ‘[Sichuan, Mt. Emei, Xixiangchi / 1800–2000 m / Chinese Academy of Sciences] [in Chinese, w, combined p and h] // [1957.VII.12 / Collector Fu-Xing Zhu] [in Chinese, w, combined p and h] // PARATYPE [y, p] // IOZ(E)1967849 [w, p] // L. prominensis [w, h]’ ( IZAS).

Diagnosis. Colouration. Body pale brown, antennae black, legs pale brown with tibiae and tarsi black.

Body length. JJ: 9.0– 9.2 mm (J ♀: 8.6–11.2 mm based on the original description).

Male ( Figs 132–135 View Figs 132–139 ). Pronotum 1.34 times as wide as long, lustrous, impunctate, anterior margin nearly straight with complete well visible border, lateral margins parallel in basal two thirds, convergent in anterior third. Posterior margin of abdominal ventrite IV with small U-shaped incision, surface around incision impressed. Metatibial spur absent.

Aedeagus ( Fig. 113 View Figs 108–117 ). Median lobe of aedeagus 3.71 times as long as wide; apical third convergent with concave margins, with distinct narrow median furrow; basal two thirds parallel. Lateral view: median lobe widely rounded in basal half, almost straigth in apical half; lateral elevation triangular, placed in anterior 1/3 of aedeagus length. Dorsal process robust, 3.65 times as long as wide, 0.64 times as long as median lobe, moderately convergent basally, with small constriction subapically; apex pointed to short triangular tip; setose plate relatively small, rounded. Lateral view: dorsal process moderately regularly rounded, narrower in middle part, with hook-like apex.

Female. Not examined.

Differential diagnosis. Liroetis prominensis is very similar in habitus to other species of L. flavipennis species-group with pale coloured dorsum. Aedeagus of L. prominensis is characterised by high triangular lateral elevations placed in anterior third of its length and which are prominent in both, lateral and dorsal, views ( Fig. 113 View Figs 108–117 ). In other species of this group with pale coloured dorsum the lateral elevations are lower and not prominent in dorsal view (cf. Figs 108–118 View Figs 108–117 View Figs 118–131 ). Distribution. China: Sichuan (JංൺඇǤ 1988).
