Polyrhachis flavicornis species-group

Species

 * Polyrhachis chaita
 * Polyrhachis fruhstorferi
 * Polyrhachis hilaris
 * Polyrhachis neglecta
 * Polyrhachis sulawesiensis

This group is characterised by the mesosomal dorsum being distinctly marginate along its entire length and by the black colour of the body (thus closely resembling some species of the subgenus Campomyrma). In contrast, the mesosoma of the redefined wallacei-group, is distinctly marginate only along the mesonotal and propodeal dorsa. The pronotal margins are completely lacking or evident only at the anterior pronotal angles and the colour of the body is yellowish-or light reddish-brown. The species of the schang species-group differ from members of the other two groups in having the lateral margins of the mesonotum distinctly raised dorsally and a completely immarginate pronotal dorsum.
