(syn. Gymnomyza Ϯ Mao G. samoensis) Gr. αμορος amoros unlucky < αμοιρεω amoireō to have no share in; genus Myza Meyer & Wiglesworth, 1895, myza. “In 1885 ... Stejneger introduced the generic name Leptomyza in combination with the species ‘Leptomyza aubryana ’. As Leptornis, the name previously used for the genus was preoccupied, it was assumed that Leptomyza was a substitute name for Leptornis ... The author’s act, however, as opposed to his intention, was to propose a new genus for the species aubryana. This detail was of little importance until 1914 when Professor Reichenow subdivided the genus Leptomyza, restricting this name to the species samoensis and viridis, while the new name Gymnomyza was proposed for aubryana alone. The case works out thus: Leptornis Hombron & Jacquinot, 1845? (type Merops samoensis Hombron & Jacquinot) proves to be preoccupied; Leptomyza Stejneger, 1885 (type Leptornis aubryana Verreaux & Des Murs) is also preoccupied; Gymnomyza Reichenow, 1914 (type aubryana) is apparently the earliest available name for either group, leaving the genus represented by samoensis and viridis without a name. For this I propose Amoromyza (type, Merops samoensis Hombron & Jacquinot).” (Richmond 1917).
