Comments The monophyly of Macrocorsinae is very strongly supported in both mtg analyses. The four genera treated in the analyses are also assigned to this subfamily by Burckhardt & Ouvrard (2012) who included another eight genera. Meanwhile, Euphaleropsis and Peregrinivena were synonymised ( Burckhardt et al . 2018b ). Trisetipsylla was placed in the Macrocorsinae by Cho et al . (2019) rather that in Psyllinae ( Burckhardt & Ouvrard 2012 ) . At least some species of Trisetipsylla have immatures with extra pore fields on the caudal plate, supporting this placement. Otroacizzia † Klimaszewski, 1996 contains the following species: O. muta † Klimaszewski, 1996 ( type species), O. prosapia † Klimaszewski, 1996 , O. soriae † Peñalver & García-Gimeno, 2006 and O. tertia † Klimaszewski, 1996 . Burckhardt & Ouvrard (2012) synonymised Otroacizzia with Euryconus . A reevaluation of the status of the four fossil species by Klimaszewski (1996) and Peñalver & García- Gimeno (2006) showed that Otroacizzia is a species mix referrable to Colophorina ( O. muta ) and to Euryconus (other species). Whereas the antennae are short and a genual spine is lacking in O. muta , the antennae are long and the genual spine is developed in the other three species. Thus, O. muta shows the characteristics of Colophorina , making Otroacizzia † a junior synonym of the former. The other three species of Otroacizzia † conform with the diagnosis of Euryconus and are transferred there. The following new synonymy and new combinations are proposed here: Colophorina Capener, 1973 = Otroacizzia † Klimaszewski, 1996 , syn. nov. Colophorina muta † ( Klimaszewski, 1996 ) comb. nov. from Otroacizzia † Euryconus prosapia † ( Klimaszewski, 1996 ) comb. nov. from Otroacizzia † Euryconus soriae † ( Peñalver & García-Gimeno, 2006 ) comb. nov. from Otroacizzia † Euryconus tertia † ( Klimaszewski, 1996 ) comb. nov. from Otroacizzia † Included genera Apsyllopsis Burckhardt & Queiroz, 2020 ; Brinckitia Heslop-Harrison, 1961 ; * Colophorina Capener, 1973 (syn. Otroacizzia †, syn. nov.); * Epiacizzia Li, 2002 ; Euphaleropsis Li, 2004 (syn.
