New locality records for species of conservation concern
by Michael Lau
Recently, a comprehensive list of terrestrial and freshwater fauna of conservation concern has been produced for Hong Kong (Fellowes, et al., 2002). The followings are sightings of some of these species made during this summer. According to the literature I have, these appear to be new locality records and hence they are reported here. The rather substantial increase in local distribution for some of the species reflects that there are still gaps in our knowledge on Hong Kong biodiversity, particularly for less known groups and at sites that are seldom visited by experts. However, some of these records were made at well-studied sites such as Tai Po Kau and they may well be examples of colonization by forest-dependent species as forest patches mature in Hong Kong.
A population of Curved-back Rice Fish (Oryzias curvinotus) was found in a stream near Wu Kau Tang on 19 April and 21 June. This species is considered to be of Global Concern.
One Baron (Euthalia aconthea) was seen in a riparian forest near Tai Ho, Lantau on 14 June 2002. It is a Local Concern species.
One Philoganga vetusta was seen by a forest stream at Ping Shan Chai on 22 June 2002. One more individual was seen at Lai Chi Wo on 26 June 2002. It is a Local Concern species.
Many Mnais mneme were seen near a forest stream near Ying Pun. Several individuals seen at Lai Chi Wo on 26 June 2002. It is a Local Concern species (Fellowes, et al., 2002).
Several Agriomorpha fusca were seen near Wang Shan Keuk on 21 June 2002. Many individuals were seen in Ping Shan Chai on 22 June 2002. One individual was seen at Lai Chi Wo on 26 June 2002. Several individuals were seen by forest seeps near Sze Tau Leng on 27 June 2002. It is a Local Concern species.
One Calicnemia sinensis was seen beside a forest stream in Shing Mun on 18 April 2002. Two more individuals were seen near a forest seep in Tai Po Kau on 10 May 2002. It is a Local Concern species.
Several Sinosticta ogatai were found near forest streams and seeps at Tei Tong Tsai, Lantau on 7 May 2002. One individual was seen in my garden at Sheung Yeung, Clear Water Bay in the morning of 15 May 2002. It left by the afternoon. It is a Global Concern species.
Several Drepanosticta hongkongensis were seen near forest streams at Tei Tong Tsai, Lantau on 7 May 2002. Two individuals were seen near a forest seep at Wu Kau Tang on 5 June 2002. Two individuals were seen by a forest seep near Sze Tau Leng on 27 June 2002. It is a Global Concern species.
One Potosticta beaumonti was seen by a forest seep near Wu Kau Tang on 19 April 2002. It is a Global concern species and this record is apparently the first from the New Territories.
Several Protosticta taipokauensis were seen near a forest stream near Ying Pun on 9 May 2002. It is a Global Concern species.
One Stylogomphus chunliuae was seen by a stream near Tai Ho, Lantau on 14 June 2002. It is a Local Concern species.
One Heliogomphus scorpio was seen by a stream near Tai Lam on 17 May 2002. It is a Local Concern species.
One Leptogomphus elegans was seen by a stream near Tei Tong Tsai, Lantau on 7 May 2002. It is a Local Concern species.
A small population of Rhyothemis triangularis was found in a weedy pond and the adjacent marsh at Wu Kau Tang on 5 June 2002. One individual was seen in a marsh on Double Island on 26 June 2002. It is a Local Concern species.
