Abstract

A new genus and species of the ant subfamily Myrmicinae collected from the Gaoligong Mountain Nature Reserve of the Hengduan Mountains, southwestern China, is described. The new genus, Gaoligongidris gen. nov., is close to Lasiomyrma Terayama & Yamane, but with anterior clypeal margin not angled, metanotal groove deeply impressed, propodeal spiracles large, propodeal spines long and slender, and petiolar peduncle longer than the node. The new genus is distributed in the Oriental region and belongs to the tribe Stenammini of Myrmicinae. A key to the known genera of Stenammini of the world based on worker and queen castes is provided.

Highlights

After the publication of the Identification Guide to the Ant Genera of the World (Bolton 1994), 14 new living genera of Myrmicinae have been established in the world
12 genera have been recognized as valid ones, and 3 genera (Lasiomyrma Terayama & Yamane, 2000; Austromorium Shattuck, 2009; Propodilobus Branstetter, 2009) belong to the tribe Stenammini (Bolton 2011)
The new genus is distributed in the Oriental region and belongs to the tribe Stenammini of Myrmicinae

Summary

INTRODUCTION

After the publication of the Identification Guide to the Ant Genera of the World (Bolton 1994), 14 new living genera of Myrmicinae have been established in the world. 12 genera have been recognized as valid ones, and 3 genera (Lasiomyrma Terayama & Yamane, 2000; Austromorium Shattuck, 2009; Propodilobus Branstetter, 2009) belong to the tribe Stenammini (Bolton 2011). Nov., was discovered in the ant diversity investigation of Gaoligong Mountain Nature Reserve, southwestern China. Nov., is the only known species of the genus. The new genus is distributed in the Oriental region and belongs to the tribe Stenammini of Myrmicinae. In order to understand the differentiation between the new genus and other ones, a key to the known genera of Stenammini is provided
