Etymology: Manuel Nuñez-Tovar

Anopheles nuneztovari is recognized by its long white ended palps and hind tarsi, broken only by the narrowest of dark bands. It also sports bushy lateral scale tufts on segments II-VII of the abdomen. Wing morphology characteristics are highly variable even within a single progeny. Anopheles nuneztovari has been exposed as a species complex on the basis of cytogenetics, isozyme analysis and molecular systematics approaches. The Nuneztovari Complex comprises An. dunhami Causey (molecularly confirmed in Brazil, Colombia & Peru), An. goeldii Rozeboom & Gabaldón (molecularly confirmed in Brazil and Suriname), and An. nuneztovari s.s. (molecularly from Bolivia, Colombia and Venezuela) and an additional five independently evolving lineages, dubbed An. nuneztovari lineages 1-5. There are three known cytotypes—nuneztovari A from Brazil, and nuneztovari B/C (which represents one species) from Colombia and Venezuela.

DIAGNOSTIC CHARACTERS  (Click photos to view; mouse over and click large photo to zoom in.)

ADULT (not illustrated): Head: Palpomere MPlp4 with white or cream-colored mediolateral scales, but no yellow scales.  Thorax: Prescutellar area with distinct small dark spot, never entirely covering whole area. Wing: Pale wing scales yellowish, at least on anterior veins; accessory sector pale spot about 0.4 from wing base, conspicuously closer to sector pale spot than to subcostal pale spot; sector pale spot on costa <0.5 x length of sector dark spot; vein M stem predominantly pale-scaled. Legs: Fe-III and Ti-III dark with sparse pale scales, not speckled; Ta-III2 with basal dark band ≥0.25 length of segment; Ta-III3 all white; Ta-III5 with basal dark band. Abdomen: At least II–VII-Te covered with scales and with posterolateral dark scale tufts.

LARVA (not illustrated): Head: Setae 2,3-C aciculate, sometimes apically branched; seta 4-C 0.3–0.6 x length of seta 3-C; seta 4-C usually single or double, moderately long, usually extending beyond the base of 2-C; setae 5–7-C plumose. Thorax: Seta 1-P with narrow lanceolate leaflets; setae 1–3-P not inserted on common tubercle.  Abdominal segments: Seta 0-II 5–8 branched, subequal or longer than length of leaflets of seta 1-II; seta 1 palmate leaflets smooth-sided; seta 6-IV,V single; seta 11-I very long, 2-4 branched; seta 13-I small, usually >3 branches.

BIONOMICS

Immatures

The immature habitats of An. nuneztovari s.l. typically include groundwater habitats including lakes, lagoons, rivers, flooded gold mines, fish ponds, ground pools, and, more rarely, tire ruts and animal hoofprints. They have been found in both still and flowing aquatic habitats, but are always associated with fresh, clear water and plentiful floating and/or emergent vegetation.

Adults

Anopheles nuneztovari s.s. (cytotype B/C) is a competent malaria vector in Bolivia, Colombia, and Venezuela. It readily enters homes and feeds on people indoors, biting late into the evening and through the night—peaking between 22:00–02:00. Anopheles nuneztovari A is thought to be primarily zoophilic, and is not incriminated in human malaria transmission. Its peak biting activity is between 18:00 and 20:00. Both An. nuneztovari s.s. and An. nuneztovari A rest outdoors.
