Notes. Gadalla (2004) recorded H. picus from Hurghada on Red Sea Coast of Egypt. In that paper, he referred only to the paper by Ahmad & Zaidi (1989), not including H. halys Stål, 1855, and there is no evidence that the author considered the now widespread and invasive H. halys at all. As a result, this record was doubted by Aukema et al. (2013), Hemala & Kment (2017) and Kment & Březíková (2018). Indeed the illustrations of a dissected female specimen provided by Gadalla (2004) suggests that the examined specimen was H. halys. This is evident by the pointed apex of the laterotergite IX (= paratergite 9) and the sessile ductuli present in the apical receptacle of spermathecal pump as shown in the illustration. The pointed apex of latertergite IX is also mentioned in the diagnosis of H. picus provided by Gadalla (2004). The above diagnostics more closely fits H. halys than H. picus. In the case of H. picus, the apex of laterotergite IX is rounded (see Salini et al. 2021: Fig. 1f) and the spermathcal ductuli are not sessile but elongate and usually twisted (Salini et al., in prep.). Moreover the nature of damage described by Gadalla (2004), resulting in the hardening of the fruit surface and taste quality loss of affected fruits, corresponds with known damage caused by H. halys. Although H. picus is known as a polyphagous pest, we are lacking reports of any serious damage or quality reduction of affected commodities by those species, except the isolated report of tender Arecanut drop by Vidyasagar & Bhat (1986).
The synonymy of Dalpada proxima Walker as well as the records of H. picus from Indochina (Laos or Vietnam) (Distant 1921, Hoffmann 1935), Malaysia (Distant 1903, 1912; Hoffmann 1935; Hasan 1993), Indonesia (Walker 1867a, Lethierry 1888, Breddin 1900, Schouteden 1933) and Philippines (Black 1968) require verification as they may belong to different species (see also Josifov & Kerzhner 1978).
Halyomorpha timorensis (Westwood, 1837) was removed from synonymy with H. picus by Kment et al. (2021).
