Genus of flies
Scaptomyza is a genus of vinegar flies, insects in the family
Drosophilidae . As of 2022
[update] , there are 273 described species of Scaptomyza .
[1]
[2]
[3]
[4]
[5]
[6] Of those, 148 are
endemic to the
Hawaiian archipelago . This genus is part of the species-rich lineage of
Hawaiian Drosophilidae , and is the sister lineage to the endemic
Hawaiian Drosophila .
[7] The genus Scaptomyza is one of several nested within the
paraphyletic genus
Drosophila .
[2]
Two hypotheses have been proposed to explain the geographical distribution of Scaptomyza.
[8] The "single Hawaiian origin" hypothesis suggests that the common ancestor of Scaptomyza and Hawaiian Drosophila colonized Hawaii once, followed by several migrations to the mainland within Scaptomyza .
[9]
[10] Alternatively, the "multiple Hawaiian origins" hypothesis suggests that the current distribution is the result of multiple colonization events (once for Hawaiian Drosophila and multiple times in Scaptomyza ).
[8]
One member of the genus in particular,
S. flava , is studied as a laboratory
model organism for
herbivory and the evolution of plant-insect interactions.
[11]
One specimen, assigned to the species
S. dominicana , has been described from
Dominican amber that is estimated to have been deposited at least 23 million years ago.
