Anopheles nigerrimus Giles, 1900




Etymology: blackest (L)

Anopheles nigerrimus is a large, dark mosquito belonging to the Nigerrimus Subgroup of the Hyrcanus Group, an assemblage of 25 species, many of which are major malaria vectors. The Nigerrimus Subgroup also includes An. nitidus Harrison, Scanlon & Reid, An. pseudosinensis Baisas, and An. pursati Laveran. Anopheles nigerrimus has five current synonyms: indiensis Theobald, bentleyi Bentley, minutus Theobald, williamsoni Baisas & Hu and venhuisi Bonne-Webster.

Type locality: Calcutta, [West Bengal], India

Type depository: Natural History Museum, London, England, United Kingdom (NHMUK)

An. nigerrimus  COI: AB778787–99, AB781757–61, LC33324




In mainland SE Asia, immature An. nigerrimus are found in deep, cooler freshwater sites, usually heavily shaded with dense aquatic vegetation, including large open marshes, large stream pools, and in fish ponds with plentiful water lettuce (Pistia stratiotes). The species raises in swampy rice fields and deep swamps with copious aquatic vegetation including Azolla, Eichhornia, Jussiaea, Hydrilla, Pistia and Spirodella in In Java and Celebes. In Sri Lanka, larval sites include agricultural and earth wells, borrow pits, rock pools and tank margins.


Biting females are most active just after dusk (18:00–20:00), and are attracted to both cattle and man. The species is a competent malaria vector in Bangladesh, Pakistan, Celebes, Java, Malaysia, and in the rice areas of southern Thailand, but has not been found naturally infected in India. Anopheles nigerrimus are common in lowlands and river valleys. Due to its association with intensive rice agriculture, evidence for insecticide resistance has been reported in this species.
