摘要
The taxonomy of Pheidole Westwood,1841 from Fujian,China is discussed.A new species,Pheidole flavigaster sp.nov.,is described.A key to the species of Pheidole based on major worker is provided.This new species is small in size,body color is brown and gaster is yellow.Pheidole flavigaster sp.nov.is similar to Pheidole schoedli Eguchi,Hashimoto&Malsch,2006 from Indonesia,but the propodeal spine is not upward and the hypostoma inner and median teeth are not distinct,making it obvious to distinguish them.The holotype and paratypes are both deposited at the Kunming Natural History Museum of Zoology,Kunming Institute of Zoology(KIZ),Chinese Academy of Sciences,Kunming,Yunnan,China.
本文对福建大头蚁属的已知物种进行了分类整理,并提供了大头工蚁分种检索表。记述采自福建省三明市瑞云山1新种:黄腹大头蚁Pheidole flavigaster sp.nov.,该新种体型较小,体棕黄色,腹部甚黄。经形态对比在中国已知物种中无一近似,与印尼地区P.schoedli近似,主要鉴别特征如下:后者大型和小型工蚁并胸腹节刺向上弯曲,前者笔直且大型工蚁咽齿不明显。该新种模式标本均保存于中国科学院昆明动物研究所(KIZ)。
