Nomenclature

 *  sauteri. Metapone sauteri Forel, 1912m: 763 (q.) TAIWAN. [Also described as new by Forel, 1913f: 189.] See also: Wheeler, W.M. 1919h: 182.

Queen
General and diagnostic features as in original description (Forel, 1912), the key to Asian species above and relevant figures. Subpetiolar extension lamellate, more-or-less evenly translucent, about twice as long as deep, very obtusely rounded-subangulate at the summit, with less-obtuse rounded angles at either shoulder; base extending back almost to the subpetiolar angle, which is drawn to an acute tooth, barely a spine. Posterior subpetiolar face acutely triangular in oblique view, with a minute barely translucent marginal carina. Dimensions: HL 2.27; HW (across eyes) 1.54; CI 68; PetW 1.13; MSL 3.60.

Type Material
Gyne; Type locality: Sokutsu, Banshoryo District, Taiwan. The type locality is frequently cited for Taiwanese specimens collected by Sauter; its exact location has apparently never been determined.
