marginella (Zicrona) Dallas 1851: 109. [ Figs 105–107 View FIGURES 105–112 ]

Original data: “ ♁ ♀ ”; “a. Hudson’s Bay. Presented by G. Barnston, Esq.” [syntypes (male and female)] LECTOTYPE ♀ (designated by Thomas 1992: 70): purple-margined lectotype disc; red-margined type disc; “Hudson’s Bay / 44 17”; “4. ZICRONA MARGINELLA ,”; “NHMUK 010592410”. Right middle leg missing ( Fig. 105 View FIGURES 105–112 ).

PARALECTOTYPE ♁: blue-margined paralectotype disc; “Hudson’s Bay / 44 17”; “ Zicrona marginella Walker’s catal.”; “NHMUK 010747388”. Second to fifth left antennomeres missing ( Fig. 106 View FIGURES 105–112 ) .

PARALECTOTYPE ♀: blue-margined paralectotype disc; “Hudson’s Bay / 44 17”; “ Zicrona marginella Walker’s catal.”; “NHMUK 010747389”. Antennae and left anterior leg missing ( Fig. 107 View FIGURES 105–112 ) .

Current status: Perillus exaptus (Say, 1825) (synonymised by Uhler 1861: 23, to Zicrona exapta ; see Stål 1870: 32; Uhler 1876: 281, placed in Perillus ).

Notes: Dallas had at least two specimens, since he listed male and female; Walker (1867a: 146) listed five specimens from the same provenance (Hudson’s Bay, Dr. Barnston). We have found three specimens in the collection. Thomas (1992: 70) stated: “The female type of Zicrona marginella Dallas was located in the British Museum (Natural History). It is labeled: (a) “Type,” (b) “ Zicrona marginella .”” With these words, he “unambiguously selected [this] particular syntype [the specimen marked as type] to act as the unique namebearing type of the taxon” ( ICZN 1999, Art. 74.5).” Burks (1975: 140) precised that, although the labels read “Hudson Bay”, Barnston actually collected his specimens at St Martin’s Falls on the Albany River, in Ontario, Canada. This locality is mentioned in the NHMUK Accessions Register under the type series registration number. Walker (1985: 15) listed the name Zicrona marginella among those of named species sent by Francis Walker to the Museum of Victoria. Public Library, Museums and National Gallery (Vic.), et al. (1890: 52) listed one specimen (Number 52875) of this species coming from Hudson’s Bay; it could be one of the two missing paralectotypes. This needs to be further investigated.
