Roell, Talita, Lemaître, Valérie A., Webb, Michael D. & Campos, Luiz A., 2023, An annotated and illustrated Type Catalogue of the predacious Shieldbugs (Hemiptera: Heteroptera: Pentatomidae: Asopinae) in the Collection of the Natural History Museum, London, Zootaxa 5232 (1), pp. 1-105 : 77

semialba (Mormidea) Walker 1868: 553. [ Figs 180–181 ]

Original data: “ a, b. Constancia, Rio Janeiro. Presented by the Rev. H. Clark. ” [two syntypes]

LECTOTYPE ♁ (designated by Thomas 1992: 80): purple-margined lectotype disc; green-margined type disc; “CONSTANCIA Jany 1857. H. Clark.”; “ Mormidea semialba .”; “NHMUK 010592333”. Fourth and fifth right and left antennomeres missing ( Fig. 180 ).

PARALECTOTYPE ♁: blue-margined paralectotype disc; “CONSTANCIA Jany 1857. H. Clark. ”; “Pentatoma Mormidea semialba Walker’s catal”; “ Asopinae 198 Podisus semialbus Walk ”; “NHMUK 010592334”. Specimen carded; third to fifth right antennomeres missing ( Fig. 181 ) .

Current status: Podisus semialbus ( Walker, 1868) (see Distant 1900a: 58).

Note: Thomas (1992: 80) explained: “The type, a male, was located in the British Museum (Natural History). It is labeled: (a) “Type,” (b) “Constancia, Jan 1857, H. Clark,” (c) “ Mormidea semialba .”” Walker lists two specimens and we have found two. By giving the labels data for one of them and calling it “the type”, Thomas has “unambiguously selected [this] particular syntype to act as the unique name-bearing type of the taxon” ( ICZN 1999, Art. 74.5).
