Myrmecina kaigong Terayama, 2009: 188, figs 252, 253 (w.) TAIWAN.

Material examined.

Unexamined. High-resolution images of the holotype of M. kaigong ( http://www.niaes.affrc.go.jp/inventory/insect/inssys/hymlst.htm, HYM- 206, photographed by Hiraku Yoshitake & Takashi Kurihara) were reviewed.

Diagnostic features.

(1) 12 - segmented antennae; (2) head with about 20 evenly spaced, thick straight rugae on the vertex (genal area smooth); (3) clypeal anterior margin straight, lacking a median denticle; (4) mesosomal dorsum with about 12 uniform longitudinal rugae (lacking deeper primary striae); (5) short triangular propodeal spines directed posteriorly; (6) petiole with a distinct dull mid-dorsal angle; (7) gastral tergite I completely smooth; (8) small body size ( TL 2.2). It differs from similar species like M. flavipeda Gu & Chen , sp. nov. (which has deeper primary mesosomal striae and a clypeal denticle) and M. taiwana (with longer, upturned propodeal spines) by these consistent traits.

Distribution.

Taiwan.
