Diagnosis. Dense setae are present on the posterior surface of the tibia equal to, or longer than, the tibial spur (see Fig. 2 b for example). The legs are yellow, except for brown front coxae and femora. The second tarsal segment is the widest of the group, being 1/3 wider than long. The wings are without any noticeable pigmentation (see Fig. 3 e). The thorax is dark brown to black, and the abdomen is mostly dark brown with the last tergum yellow, and the preceding tergites marked with yellow laterally.
Types: MAUI: Holotype ɗ (BPBM 6344) Waikamoi, 1220 m, vii.1956, DEH. Locality recorded as “Wai a kamoi” on type label (Evenhuis 1982).

Distribution. This species is endemic to Maui Nui and the Big Island of Hawai‘i.
Behavior. Speith (1966: 273); Grossfield (1968); Kambysellis and Heed (1971).
Chromosomes. The metaphase complement of this species is 5 rods and 1 dot (Clayton 1969; Yoon & Richardson 1978).
Ecology. Nutritional requirements (Robertson et al 1968); This species has been reared from leaves of Cheirodendron trigynum (Araliaceae) from Hawai‘i, Maui, Moloka‘i and Lana‘i; leaves of Tetraplasandra sp (Araliaceae) from Hawai‘i; leaves and stems of Clermontia sp (Campanulaceae) from Hawai‘i and Lana‘i; leaves of Myrsine lessertiana (Myrsinaceae) from Moloka‘i; leaves of Pittosporum sp (Pittosporaceae) from Moloka‘i (Heed 1968; Magnacca et al 2008; Mangan 1978).
Illustrations. Morphological structures of this species are depicted in multiple publications including: egg (Kambysellis and Heed 1971: 34, fig. 2.3; 36, figs. 4.1, 4.2); foreleg (Hardy 1965: 250, fig. 82a); ovary (Kambysellis and Heed 1971: 35, fig. 3.1); phallus (Kaneshiro 1976: 267, fig. 5e); terminalia, female, lateral (Hardy 1965: 250, fig. 82b); terminalia, male, lateral (Hardy 1965: 250, fig. 82c); Takada 1966: 318, fig. 1.8).
Molecular Biology. DNA sequences (Kambysellis & Craddock 1997; O’Grady & DeSalle 2008; O’Grady & Zilversmit 2004).
Discussion. Drosophila waddingtoni has the widest range of any spoon tarsus group species and is found throughout Hawai‘i and Maui Nui. Several individuals from Maui have been collected that grade in coloration of the tibia from yellow (normal) to dark brown.
