Anopheles sarpangensis Somboon, Namgay & Harbach is described as a new species of the Barbirostris Complex of the subgenus Anopheles Meigen. The adults differ from other species of the complex in having wings with a prehumeral pale spot on the costa, foretarsomere 1 with an apical pale band more than half as long as foretarsomere 5, midtarsomeres 1 and 2, and occasionally 3 and 4, with incomplete apical pale bands, and abdominal sterna with many white scales as in An. campestris Reid, An. saeungae Taai & Harbach, and An. wejchoochotei Taai & Harbach. The pupa and larva are indistinguishable from the pupae and larvae of other species of the complex. Phylogenetic analysis revealed that COI sequences form a clade separate from clades consisting of the sequences of other species of the complex. The immature stages were commonly found in fishery ponds in foothills at low to moderately high altitudes in the Sarpang District of Bhutan.

不丹按蚊复合体新种（双翅目：蚊科）

萨班按蚊 Somboon、Namgay 和 Harbach 被描述为梅根按蚊亚属 Barbirostris Complex 的一个新种。成虫与该复合体的其他物种的不同之处在于，其翅膀的肋部有肱前浅色斑点，第1前体有一条顶端浅色带，长度超过前体5的一半，中体1和2，偶尔有3和4，不完整顶端呈淡色带，腹部胸骨有许多白色鳞片，如安。油菜里德，An. saeungae Taai 和 Harbach，以及 An。wejchoocotei Taai 和 Harbach。蛹和幼虫与复合体中其他物种的蛹和幼虫没有区别。系统发育分析表明，COI 序列形成一个分支，与由复合体其他物种的序列组成的分支分开。未成熟阶段常见于不丹萨尔邦地区低至中高海拔山麓的渔业池塘中。
