  abstract = {{W}e studied the geographical distribution of species, chromosomal, and molecular forms of the {A}nopheles gambiae {G}iles ({D}iptera: {C}ulicidae) complex in 23 sites in {C}ameroon, {C}entral {A}frica. {A}lmost all the specimens collected in the four northern-most and sites were {A}nopheles arabiensis. {A}nopheles melas was found in a rural locality surrounded by mangrove swamps, on the {A}tlantic {C}oast. {I}n total, 1,525 {A}n. gambiae s.s. females were identified down to their molecular form, and inversion polymorphisms on polytene chromosomes were scored from 186 half-gravid females. {T}he {F}orest chromosomal form, with standard arrangements almost fixed on both arms of chromosome-2, was the only one observed in the southern, more humid localities. {K}aryotypes typical of {S}avanna and {M}opti were recorded northwards, in the humid savannas of the {A}damawa {P}rovince. {T}he molecular forms {M} and {S} were widespread throughout {C}ameroon, and assort independently from the chromosomal forms. {S}-form populations were characterized by karyotypes typical of {F}orest and {S}avanna chromosomal forms, and {M}-form populations were characterized by karyotypes typical of {F}orest, {S}avanna, and {M}opti. {N}o {M}/{S} hybrid patterns were detected, although {M} and {S} mosquitoes were sympatric in 15 sites, providing further evidence for positive assortative mating within molecular forms. {T}he observed ecogeographical distribution of {M} and {S} was peculiar: the ecological parameters involved in this distribution still need to be clarified as well as the possible role of competitive exclusion between chromosomally homosequential molecular forms. {N}o difference was observed in host preference or in {P}lasinodium falciparum infection rates between sympatric {M} and {S} populations.},
