(SYSU): ‘ Lam Tsuen valley, Ng Tung Chai Village’ (= Wutong Village), ‘ 70 m altitude in moss at the edge of trickling stream’ (present with <i>C. indica</i>), ‘ 19.i.2013, Paul Aston leg’; 1 male (PCPA): ‘ Lantau, Tai O’ (= Da Ao), ‘ 40m altitude, thick wet moss at edge of narrow ditch with shallow stagnant water, 25.iii.2012, Paul Aston leg’; 2 male (PCPA): ‘ Lantau, Tai O’ (= Da Ao), ‘ 40m altitude, thick wet moss at edge of narrow ditch with shallow stagnant water, 26.xii.2012, Paul Aston leg’. <b>HAINAN</b>: 1 male (SYSU): ‘ Wenchang, Tongguling Nature Reserve, 317m, light trap, 18.iii.2008, Yang Yuxia leg’.
