Etymology: not known [in German (third rib without a black spot toward the base); possibly refers to absence of dark spot on R separating sector pale spot from the accessory sector pale spot]
Anopheles aconitus belongs to the Aconitus Subgroup (Funestus Group), together with An. filipinae Manalang, An. mangyanus (Banks), An. pampanai Büttiker & Beales, and An. varuna Iyengar. Anopheles aconitus has two recognized synonyms: An. albirostris Theobald, An. brahmacharii Christophers. Four karyotypic forms of An. aconitus have been reported - Form A (X1, X2, Y1), Form B (X1, X2, Y2), and Form C (X1, X2, Y3), all found in sympatry in Maetang District, Chiang Mai Province, northern Thailand, and Form D (X3, X4, Y4) from Java, Indonesia. A recent SEM study on egg morphology and morphometrics concluded that karyotypic form B and C are conspecific.

DIAGNOSTIC CHARACTERS (Click photos to view; mouse over and click large photo to zoom in.)
ADULT (illustrated): Head: Proboscis pale distally; palpus with 3 pale bands; preapical dark palpal band variable from as long as the two adjoining pale bands to completely absent; vertex with white erect scales. Thorax: Antepronotal scales absent; anterior promontory with long, white, slender scales; scutum center appearing nearly bare except for setae, or with slender seta-like pale scales reaching to scutellum. Legs: Legs entirely dark or with narrow apical pale bands or dorsal patches on some tarsomeres. Wing: Costal area with ≥4 dark spots; hind margin of wing usually with pale fringe spot at vein 1A; vein 1A with two dark spots on distal 0.5; vein R2 with median pale spot. Abdomen: Abdominal segments VII and Vlll and female cercus without scales.
LARVA (not illustrated): Head: Seta 2-C aciculate; seta 4-C branched. Thorax: Only 1 of setae 9,10-T single. Abdominal segments: Tergal plates on segments IV-VII large, enclosing small median accessory tergal plates.

Exemplar DNA sequences
An. aconitus COI: AY423055, DQ000253-64
Immature An. aconitus s.l. are found in clear, fresh water sites with little or no water movement, including rice fields, ponds, marshes, swamps, river bed pools, ditches, and irrigation channels. Reports exist of immatures collected in wells, wheel ruts and hoof prints.
Anopheles aconitus s.l. are common in agricultural lands and forest edge habitats, from sea level to 800 m (occasionally at 1000 m). Peak adult abundance coincides with rice harvests (March–April, August–September), when plants are around 1.5m high. Although primarily zoophilic, Anopheles aconitus s.l. will readily feed on man in areas where cattle are scarce. The species are both exophilic and endophilic, feeding from dusk to around midnight, and can play a significant role in malaria transmission at high densities. Anopheles aconitus karyotype form B/C is susceptible to laboratory infection with both Plasmodium falciparum and P. vivax. Indonesian populations of An. aconitus (presumably form D) are considered primary malaria vectors, but the vector status of Form A remains unknown.
