Mainland: Beja ( Valente & Hodkinson 2009; Bella 2013; this study, iNaturalist, Appendix 1); Bragança (iNaturalist, Appendix 1); Castelo Branco ( Valente & Hodkinson 2009; iNaturalist, Appendix 1); Coimbra (iNaturalist, Appendix 1); Évora ( Valente & Hodkinson 2009); Faro ( Valente & Hodkinson 2009; this study; iNaturalist, Appendix 1); Lisbon ( Moreira 2009; this study; iNaturalist, Appendix 1); Guarda, Portalegre ( Valente & Hodkinson 2009); Santarém ( Valente & Hodkinson 2009; iNaturalist, Appendix 1); Setúbal (iNaturalist, Appendix 1).

Host plants Portugal. Myrtaceae : Eucalyptus camaldulensis Dehnh. ( Valente & Hodkinson 2009; Bella 2013; Dhahri et al. 2014), E. cypellocarpa F.Muell. , E. grandis W.Hill , E. macarthurii H.Deane & Maiden , E. nicholii Maiden & Blakely , E. nitens (H.Deane & Maiden) Maiden , E. ovata Labill. , E. pauciflora Sieber , E. pilularis Sm. , E. propinqua Deane & Maiden , E. pulverulenta Sims , E. regnans F.Muell. , E. resinifera Sm. , E. rudis Endl. , E. sideroxylon A.Cunn. ex Woolls , E. tereticornis Smith , E. viminalis Labill. ( Dhahri et al. 2014) .

Dhahri et al. (2014) evaluated the susceptibility of various Eucalyptus spp. to attack by G. brimblecombei in a survey carried out in a eucalypt arboretum in Lisbon in 2012. The authors showed that E. camaldulensis , E. ovata and E. tereticornis were highly susceptible (with 40.4% to 68.4% of leaves attacked) while E. cypellocarpa , E. grandis , E. marcarthurii , E. nicholii , E. nitens , E. pauciflora , E. pilularis , E. propinqua , E. pulverulenta , E. regnans , E. resinifera , E. rudis , E. sideroxylon and E. viminalis were considered moderately to barely susceptible (ranging from 26.9% to 0.6% attacked leaves). Another 13 species ( E. botryoides , E. cinerea , E. citriodora , E. creba , E. globulus , E. goniocalyx , E. maculata , E. meliodora , E. occidentalis , E. perriniana , E. polyanthemos , E. robusta and E. saligna ) were resistant to attack by Glyscaspis brimblecombei .

Parasitoids. Dhahri et al. (2014) reported the presence of the parasitoid Psyllaephagus bliteus Riek

( Hymenoptera : Encyrtidae ) for the first time in mainland Portugal.
