金蚁属Parvimyrma是越南北部发现的一个新种。该属无疑属于扶桑属，它与属于该属组的其他属的区别在于以下特征的结合：扶桑属的后中间部分狭窄地插入额叶之间；下颌骨咀嚼缘具5离生牙齿；天线11节段，具有2节段短杆；眼睛完全无；在侧面的前凸几乎平或非常弱凸背；金属槽相对浅，背面凹陷；propodeum手无寸铁的;鼻突小，位于鼻突两侧的中间长度后面一点；胸膜后腺大；叶柄具一小的前腹突；后叶柄狭地附生于腹肌最前端；刺发育不良。
The myrmicine ant genus Parvimyrma is newly established for a single new species found from N. Vietnam. The genus is undoubtedly placed in the Solenopsis genus group, and it is distinguished from the other genera belonging to the genus group by a combination of the following features: posteromedian portion of clypeus narrowly inserted between frontal lobes; masticatory margin of mandible with 5 distinct teeth; antenna 11-segmented, with a 2-segmented club; eye completely absent; promesonotum in profile almost flat or very weakly convex dorsally; metanotal groove relatively shallowly impressed dorsally; propodeum unarmed; propodeal spiracle small, situated a little behind the midlength of the sides of propodeum; metapleural gland large; petiolar peduncle with a small anteroventral process; postpetiole narrowly attached to the anteriormost end of gaster; sting poorly developed.
