( Figs. 3 , 9–10 , 18–19 , 22 )

Phyllodrepa musaphila Rougemont, 2017: 261

Material examined: 1 Ƌ [specimen dissected]: ‘ CHINA: Jiangxi prov. [MF-15] | Jinggangshan Mts., Wankeng | (stream valley), 28.iv.2011 | 26°31.8’N, 114°11.8’E, 525 m | Fikáček, Hájek, Jia & Song’, ‘spring with a gravel | bottom | rotten bamboo trunk + | decaying cut tops of bamboo | trunks’ ( NMPC) .

Remarks. Phyllodrepa musaphila Rougemont, 2017 was described from Hong Kong. During the study of the Omaliinae material from NMPC, I found a male from Jiangxi Province of China which belongs to this species. Based on the morphological characters listed above (see Introduction), the species belongs to the genus Omaliopsis . Thus, a new combination is proposed here. Habitus as in Fig. 3 . Abdominal tergite VIII of male as in Fig. 9 . Abdominal sternite VIII of male as in Fig. 10 . The species displays unusual bilobed apical part of the median lobe ( Fig. 18 ). Aedeagus laterally as in Fig. 19 .
