74.7%). However, there are also areas where this species is not present as in research by Chen (2002), Foley (2008). In China, An. minimus is almost absent in the north [88], and is only present in the south from 32

5 going down, including Yunnan, Guangdong, Guangxi, Taiwan and Hainan Islands [65], [71]. Some studies state that An. minimus ss. is absent or rare in Indonesia and the Philippines, while An. flavirostris with the similar morphology to An. minimus is present in these islands [97]. In addition, An. flavirostris has also been identified as a malaria transmission vector in some West Asian countries such as Nepan, Pakistan [71]. It is likely that there is an overlap in the distribution of An. minimus and An. flavirostris in some countries According to the research results in Vietnam by Nguyen Huu Duc (1973), An. minimus was popular at elevations from 0 to 800 m. In this study, we did not assess the elevation but selected survey sites based on malaria epidemic areas, because the area of endemic malaria exists transmission vectors.
