Etymology: Sulawesi, Indonesia
Anopheles sulawesi of the Leucosphyrus Subgroup (Neomyzomyia Series) is a Sulawesian endemic—found only on Sulawesi and some small adjacent islands, including Boeton, Kaboena, Sangihe and Talaud. The combination of a long proboscis (c. 1.25 x forefemur) and shorter palps (0.85–1.15 x forefemur) in An. sulawesi are shared with An. elegans (James), An. hackeri Edwards, and An. pujutensis Colless (also Leucosphyrus Subgroup) and differentiates these species from all other anophelines in the Oriental region. Anopheles sulawesi is rcognized by the presence of 1–4 spots in the presector dark spot on vein R—absent in An. hackeri and An. pujutensis. Anopheles sulawesi larvae are also distinctive in the length and placement of seta 4-C.

DIAGNOSTIC CHARACTERS (Click photos to view; mouse over and click large photo to zoom in.)
ADULT (illustrated): Head: Palpus with apical pale band c. 2x length of preapical dark band; MPlp5 mainly dark-scaled; proboscis mainly dark-scaled with band of pale scales at apex, basal to labella. Wings: Both M and M3+4 veins noticeably wavy; accessory sector pale spot absent from costa, present on vein R; presector dark spot on vein R with 1–4 pale interruptions; preapical dark spot of vein R1 with 1–4 pale spots; 6–10 pale interruptions from presector dark to preapical dark area of vein R1; sector dark spot of vein R1 with 2–5 pale spots. Legs: Ti-III apical pale band with narrow dark longitudinal extension on ventral surface in addition to separate dark spot; Ta-III2–5 without basal pale scales. Abdomen (dorsal): VIII-Te with posterior golden scales.
LARVA: Head: Seta 3-C single, extending beyond head margin; seta 4-C long, extending well beyond base of 2-C; seta 5-C conspicuously longer than antenna. Thorax: Seta 1-M basal sclerotized tubercle without a distinct pointed or angular tooth; seta 1-P basal sclerotized tubercle with prominent tooth on posterodorsal margin. Abdominal segments: Seta 1-II not fully developed palmate; individual leaflets of palmate setae with long and slender apical filaments; tergal plate on segments IV,V about 2x wider than deep, accessory plates usually absent.

Exemplar DNA sequences
An. sulawesi COI: DQ897967
Immature An. sulawesi have been collected from shaded rock pools, and in marginal pools overhung by vegetation and in drying river beds. Preferred habitats are typically lined with dead decaying leaf matter or thick black muddy soil substrates, and waters usually have a high organic content.
Anopheles sulawesi is the primary vector of malaria in Sulawesi. Little is known on the bionomics of the species, but two blood fed specimens in the U.S. National Collection bear labels indicating human feeding behavior; and another is labeled “Indoor-resting”. Surprisingly, a human landing collection conducted between 18:00 and 23:00 over three nights, only 3–5 m from the larval sites, reported no human landing captures of the species. This suggests either that the species either bite later in the night, perhaps that the newly emerged females fly away from the emergence sites before host seeking.
