Adult male. Male genitalia with dorsal lobe of claspette having 3 closely appressed setae of about equal length. Aedeagus with 5 leaflets on each side; 2 most mesal leaflets with broader transparent inner margins than other leaflets. Tergum IX bare, with pair of caudally directed elongate capitate lobes. Pupa. Trumpet with thin, lightly serrated pale brown rim (like An. sinensis and An. belenrae , and unlike An. lesteri having thick serrated rim). Wing sheath with distinct rows of round dark spots (like An. sinensis and An. belenrae , and unlike An. lesteri having checkered dark stripes). Setae 9­III­VII single, with narrowly rounded apex (like An. lesteri and An. belenrae ); seta 5­V with 5–13 branches. Larva. Setae 2­C, 3, 5­M single; 3­P single or forked; 3­C with 11–23 branches; 4­M with 3–8 erect branches; 9­M about 1.5x length of 10­M, T; 5­III with 9–13 branches; 9­III with 5–11 branches; 13­IV with 4–9 branches; 1­X strong, single less than length of saddle (unlike An. lesteri about 2x or more longer than the saddle); pecten with 8–9 long spines and 10–17 short spines.

Etymology. The species is named after Colonel Terry A. Klein, medical entomologist, for his numerous contributions to mosquito research in Asia.

Remarks. The specimens used in this study were progeny reared from adults that were collected in cow sheds at villages with rice paddies. Nothing is known about the natural habitats of the immature stages. The ribosomal DNA ITS2 sequence of An. kleini is provided by Li et al. (2005, Figure 1 , Anopheles “unknown 2”).
