Lycianthes amatitlanensis (J.M.Coult. & Donn.Sm.) Bitter (1919: 441) ≡ Solanum amatitlanense J.M.Coul. & Donn.Sm. in Donnell Smith (1904: 420). Type (lectotype, designated here):— GUATEMALA. Alta Verapaz: Cubilqüitz, 350 m, Feb 1903, von Tuerckheim 8488 (US barcode 01269192!, isolectotypes F barcode 0073066F [digital photo!], M barcode M-0171813 [digital photo!], NY barcode 00138963 [digital photo!], NY barcode 00138964!, US barcode 01014253!; image of the lectotype is available at https://collections.nmnh. si.edu/search/botany/). Nomenclatural notes:— Donnell Smith (1904) cited three gatherings in the protologue with no herbaria specified: von Tuerckheim 8488, von Tuerckheim 7753, Donnell Smith 1457. We traced several specimens in the herbaria F, GH, K, M, NY, and US belonging to the cited gatherings: von Tuerckheim 8488 (US barcode 01269192, F barcode 0073066F, M barcode M-0171813, NY barcode 00138963, NY barcode 00138964, US barcode 01014253); von Tuerckheim 7753 (NY barcode 00138966, US barcode 01014252, US barcode 01269193); Donnell Smith 1457 (F barcode 0073065F, GH barcode 00077435, K barcode K000585748, US barcode 00027445). These specimens completely agree with the protologue and with the current application of the name (Benitez de Rojas and D’Arcy 1997, Dean 2018) and can be safely considered as original material (Art. 9.3. of the ICN, McNeill et al. 2012). The von Tuerckheim 8488 specimen at US (US barcode 01269192) is selected here as the lectotype for the name Solanum amatitlanense. Taxonomic notes:— Lycianthes amatitlanensis, a member of Bitter’s cohesive series Strigulosae (Bitter 1919), is a small shrub with simple, strigose trichomes that ranges from southern Mexico to South America (Benítez de Rojas and D’Arcy 1997; Villaseñor 2016). With further study, this name may be synonymized with the South American L. inaequilatera (Rusby 1896: 90) Bitter (1919: 439).
