Abstract
A new species of the ponerine ant genus Myopias Roger, 1861 collected from southwestern China is described based on morphological features. M. daia sp. nov. is allied to M. luoba Xu & Liu, 2012, but differs from the latter by the shape of the posterior head margin, eye facet number, petiolar node shape, head sculpture, body color, and total length. The new species is also allied to M. nops Willey & Brown, 1983 and M. menba Xu & Liu, 2012, but differs from the latter two species by petiolar node shape, eye facet number, and body sculpture and color. A key based on the worker caste is provided to the eleven known Oriental species of the genus for the first time.
Highlights
The ponerine ant genus Myopias Roger, 1861 is distributed in the Oriental, Indo-Australian, and Australasian regions of the world (Bolton, 1995)
In order to identify the Oriental species and understand the differences between the new species and previously known ones, we provided a key for the worker caste based on the specimens of southwestern Chinese species, AntWeb images, and original descriptions
Comparative notes: This new species is allied to M. luoba Xu & Liu, 2012, but differs from the latter by having straight posterior head margin in full-face view
Summary
The ponerine ant genus Myopias Roger, 1861 is distributed in the Oriental, Indo-Australian, and Australasian regions of the world (Bolton, 1995). A survey of ants in Yunnan Province, China, conducted during the Queensland Chinese Academy of Sciences (QCAS) Biodiversity Project, has discovered a new species of Myopias described below. HL-Head Length: The straight-line length of the head in perfect full-face view, measured from the mid-point of the anterior clypeal margin to the midpoint of the posterior margin. PL-Petiole Length: The length of the petiole measured in lateral view from the anterior process to the posteriormost point of the tergite, where it surrounds the gastral articulation.
