Distribution. Known in the Palearctic Region from the Himalayan countries of Nepal, Bhutan, and the Sikkim Province of India, as well as the Chinese provinces of Guizhou, Jiangxi, Yunnan, and the island of Taiwan ( Bezdek 2016 ). It has only recently been recorded from Hong Kong for the first time ( Aston and Melsom 2019 ). In the Oriental Region, it has been reported from Myanmar, Vietnam, Thailand, Laos, India and Sri Lanka ( Sakai and Nagai 1998 ; Krajcik 2011 ). Material examined. 1♂ : Taipa Monument , 27 Sep 2018 , dead on path, R Perissinotto (MACT) ; 1♀ : Coloane Village , 28 Aug 2019 , on flowers of Zanthoxylum avicennae , R Perissinotto & L Clennell (MACT) . Other Macau records. Macau, Guia Hill, 25 Oct 2017, R Perissinotto & L Clennell; Taipa Pequena, 4 May 2018, R Perissinotto & L Clennell; ibidem 11 Oct 2018, R Perissinotto & L Clennell; Macau Peninsula, 22 Dec 2019, Angus Chan (pers. comm.); Coloane, Hac-Sa , 7 Apr 2020, on flowers of Ligustrum sinense , R Perissinotto & L Clennell. Remarks. This species appears to be a new record for the broader region, having also been observed for the first time in Hong Kong only in April 2018 ( Aston and Melsom 2019 ). The subspecies G. h. chinensis , originally described by Miksic (1970) based on its wider extent of the red pronotal margin over the nominal subspecies (e.g., Ma 1995 ), is no longer recognised and has been synonymised with G. horsfieldii ( Jakl in Loebl and Loebl 2016 : 18). Specimens in Macau range in size from approximately 13 to 16 mm TL and from 6 to 8 mm MW. The period of adult activity seems to extend throughout the year, but most observations are from the spring (Apr-May) and autumn (Sep-Oct) months. While the larval stages are not known, adults have been recorded on flowers of Ligustrum sinense , Zanthoxylum avicennae , Shefflera heptaphylla and Homalium cochinchinense . Figure 5.
