marginella (Canthecona) Dallas 1851: 89. [ Fig. 104 ]

Original data: “ ♁”; “a. Sierra Leone. Presented by the Rev. D.F. Morgan. ” [syntype (s)]

SYNTYPE ♁: blue-margined syntype disc; red-margined type disc; “87 a”; “ Canthecona marginella identified by Dallas.”; “a”; “NHMUK 010592170”. Fourth and fifth right antennomeres, second to fifth left antennomeres, and left posterior leg missing ( Fig. 104 ).

Current status: Afrius purpureus (Westwood, 1837) (first synonymised to Canthecona Yolofa (Guérin-Méneville, 1831) , as a var. by Stål 1862a: 496; synonymised by Stål 1870: 44; see Roell et al. 2019: 25).

Notes: Walker (1867a: 130) listed one specimen from Sierra Leone under the name Canthecona yolofa . It is likely that Dallas only described the species from this unique specimen (especially as he stated only one measurement and noted: “Antennae black (two apical joints wanting).” [emphasis ours]), but we cannot be sure, we therefore consider it a syntype. The label “87a” refers to the first specimen on page 87 in the first volume of Adam White’s unpublished “Catalogue of Hemiptera ” (White, A., no date) There, reference is made to a record in Samouelle’s Register: “Reg. 1224”. On page 182 of Samouelle’s Register ( Entomological Memorandums, 1838 –1840), we can find information on the determination of the specimen: “ Pentatoma ” and on its provenance: “ Sierra Leone Rvd Morgan”. A cross-reference to White’s Catalogue of Hemiptera is as well noted: “Cat. Hem. II 87a”. For further informations on White’s Catalogue of Hemiptera and other early catalogues at the Museum, see Wheeler (1996).
