Metapone sauteri

Known only from the holotype queen.

Identification
Head relatively narrow (HW 1.54, CI 68). Petiolar node in dorsal view more than twice as long as wide, with strong posterolateral tooth-like projections. Subpetiolar extension a long, low subrectangular, translucent lamina extending back almost to the subpetiolar angle; the latter acutely spine-like in lateral view. (Taiwan, gyne only, Figs 28–33)

Distribution based on Regional Taxon Lists
Oriental Region: Taiwan.

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.
