Stenochorus antennatus Gyllenhal, 1817: 180. TL: India ( “orientali”); TD: NHRS

Distribution.

Palaearctic Region: China (Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hainan, Hebei, Henan, Hong Kong, Hubei, Hunan, Jiangxi, Shaanxi, Shandong, Taiwan, Zhejiang) ( Yiu 2009; Danilevsky 2020). Oriental Region: India (eastern) ( Gressitt 1951; Švácha et al. 1997).

Macau records.

São Francisco Xavier, Ilhas [Coloane], 1 May 2021 8:37, Kisu Wong (https://www.inaturalist.org/observations/76970773); Coloane, Barragem de Ká-Hó, 1 May 2021 8:30, Wai Chan (https://www.inaturalist.org/observations/76102979).

Remarks.

Only two observations of male specimens from Macau could be found in the citizen science platform iNaturalist, but unfortunately the accompanying data did not contain any information about their size or habits. A third observation of a female specimen could not be confirmed due to the poor resolution of the photograph (https://www.inaturalist.org/observations/78005663). On Plate IV of Hua et al. (2009), the male represented in Fig. 40 is actually that of Philus pallescens , while the females in Fig. 40 and Fig. 41 represent the same specimen of P. antennatus . Unfortunately, their figure legends on p. 4 reflect this mistake. In Hong Kong, specimens attain a total length within the range of 24-31 mm ( Yiu 2009). The mature larva of this species has been comprehensively described by Švácha et al. (1997) and feeds on the roots of a range of plants, including cultivated species such as Citrus spp., Morus alba , Pinus elliottii , and P. taeda , to which it can cause serious damage and death in young trees ( Gressitt 1951; Chen et al. 1959; Švácha et al. 1997).
