Gran Canaria : 2 ♀ , Arteara near Fataga , 6.xii.1988 ( E. Heiss ) ( NHMB , dry mounted). Comments. This is an undescribed species; more material is required in order to make a formal description. ‡ Trioza erytreae ( Del Guercio, 1918 ) Material examined. 1 ♂, 19.vii.2011 , Allium cepa (F. Siverio) ( NHMB , 70% ethanol); 1 ♂, Valle de Guerra , 28.5118 N , 16.3930 W , 300 m alt ., 7.v.2018 , Citrus sinensis (S. Bastin) ( ICIA , slide mounted); 4 ♂, 2 ♀ , Pedro Alvarez , 28.5300 N , 16.3086 W , 620 m alt ., 22.ii.2019 , Convolvulus canariensis (A. González & S. Bastin) ( SBPC , slide mounted, 70% ethanol); 1 ♂, same data but 1.iv.2020 , C. canariensis (S. Bastin) ( ICIA , 70% ethanol) . Description. Adult and fifth-instar immature. Coccuzza et al . (2017). Distribution CI. Tenerife ( Pérez Padrón & Carnero Hernández 2002 ), El Hierro, La Palma, La Gomera, Gran Canaria ( Cocuzza 2017 ). Host plant CI. Citrus limon , C. sinensis (Rutaceae) . Comments . In the mitogenome analysis by Percy et al. (2018) , Trioza erytreae was recovered in clade D, forming a poorly supported clade together with some Oceanic species referred to the ill-defined genera Anomocephala Tuthill , Cerotrioza Crawford, Kuwayama Crawford and Megatrioza Crawford , as well as the Palaearctic Heterotrioza Dobreanu & Manolache. It is, therefore, phylogenetically unrelated to T. urticae , the type species of Trioza , which falls in clade M. Hollis (1984) defined the erytreae -group as containing ten Afrotropical species but conceded that the group is difficult to delimit from other Trioza species and that it might well be an artificial assemblage. We conclude that T. erytreae should be excluded from Trioza but refrain from erecting a new genus pending a thorough revision of the Oceanic members of Anomocephala , Cerotrioza , Kuwayama and Megatrioza and the Afrotropical species of the erytreae -group. Biology . Since the introduction of the parasitoid wasp Tamarixia dryi ( Waterston, 1922 ) ( Hymenoptera : Eulophidae ) in the context of a biological control programme in 2019, Trioza erytreae has become rare; only a few specimens have been observed since (Hernádez-Suárez et al. 2020).
