Subgenus Egadroma Motschulsky, 1855

Stenolophus (Egadroma) quinquepustulatus Wiedemann, 1823

It seems surprising that Yu & Tang (2002) and Jaeger & Kataev (2003) were the first to document its occurrence in Hong Kong. Andrewes and Scott (1924) found it under stones in Macao under the name Stenolophus smaragdulus variation quinquepustulatus Wiedemann 1823 . In Hong Kong, there are 4 distinct forms, the darkest having a completely unmarked elytra and can only be determined by the genitalia. Material: 1 ex. W.T.L., 12.ii.16; 1 ex. W.T.L., 18.iii.09; 1 ex.

Stenolophus (Egadroma) ovatulus ( Bates, 1889)

New record for Hong Kong. This mainly South East Asian species has been recorded in Hainan and Fujian Provinces ( Kataev & Wrase 2013), and so should be expected in Hong Kong.
