Etymology: yellow beak (L); proboscis
The tiny species An. flavirostris is recognized by three distinct pale bands and a yellow tip to its proboscis, and three large pale spots on the leading edge of its wing. Morphologically, An. flavirostris is very close to An. minimus Theobald. It was long regarded as a subspecies of An. minimus until DNA and hybridization studies, along with differences in the cibarial armature, confirmed the separate species status of these taxa. The two species have been routinely misidentified, leading to confusion in assigning bionomic traits and vector competency. All historical records of An. minimus from the Philippines, Indonesia and eastern Borneo are now attributed to An. flavirostris. Anopheles flavirostris belongs to the Minimus Subgroup, along with together with An. leesoni Evans, and An. longipalpis (Theobald).

Abdominal segments: Seta 0-IV–VI arising just posterolateral to tergal plate, or just on or at edge of plate; seta 0-IV–VII small, 1-2 branched; tergal plates on III–VII very large, ≥0.5 width of segment, enclosing small median posterior accessory plate; tergal plates rounded posteriorly.

Exemplar DNA sequences
An. flavirostris ITS2: AB088384, AY943666, GU062188, GQ500121
Immatures are typically found in shaded portions of clear, slow-flowing sites—streams, canals, drainage ditches and seepage pools—with emergent vegetation, particularly those close to human habitation. They are never found in stagnant or saline waters.
Anopheles flavirostris is most closely associated with lowland foothills, but specimens have been collected from sea level up to 1,500m. Large mammals including buffalos, cows and people are the preferred hosts of An. flavirostris, and biting occurs throughout the night, peaking towards midnight. In eastern Borneo (Sabah & East Kalimantan), An. flavirostris is highly anthropophilic, and will enter houses to feed, whereas, in other islands of the Indonesian archipelago, it is rarely collected at human bait, is predominantly exophilic, and is only regarded as a secondary vector. In the Philippines, the species serves as a low-level maintenance vector of malaria.
