Rekoa marius (Lucas) : Robbins (1991), Beccaloni et al. (2008), Warren et al. (2015)

Rekoa zebina is a Central American species that resembles R. marius and R. stagira (Hewitson) ( Robbins 1991) . Kaye’s (1940) original report was based on two specimens collected by F.W. Jackson (St Joseph 5.iv.1922; Balata Hill 28.iii.1922) but these have not been located in BMNH (main sequence) or OMNH. The series in Barcant’s collection appears to comprise seven R. marius and two R. stagira , but the specimen illustrated ( Barcant 1970, plate 28.24) is not in his collection now.

Rekoa stagira (Hewitson, 1867)

Thecla stagira Hewitson : Crowfoot (1893, no. 147)

Tmolus stagira Hewitson : Kaye (1904, no. 145, citing Crowfoot (1893))

Siderus voltinia (Hewitson) : Barcant (1970, no. 345) [misidentification, part]

Rekoa stagira (Hewitson) : Robbins (1991), D’Abrera (1995, p. 1250), Sookdeo (2013), Warren et al. (2015)

S. voltinia is a synonym of Kolana ergina (Hewitson) ( Robbins 2004) , and we assume that represents Kaye’s (1921) use of the name. In his collection, Barcant curated what appear to be four Rekoa stagira and five R. marius as Siderus voltinia . The specimen illustrated ( Barcant 1970, plate 28.24) is a male R. stagira in his collection.
