Polyrhachis luctuosa

Identification
Polyrhachis luctuosa is closely related to Polyrhachis inflata, with both distinguished from all other known New Guinean species by the very closely reticulate-punctate sculpturation of their body, giving them a distinct, opaque appearance. However, Polyrhachis inflata is easily distinguished from Polyrhachis luctuosa by its exceptionally high pronotal dorsum which bears a well-defined, median, longitudinal furrow along its summit. The pronotum in Polyrhachis luctuosa is not swollen and has no furrow on its summit. (Kohout 2006)

Distribution
Polyrhachis luctuosa is apparently very rare and, besides the type, only one additional specimen was collected by R.W. Taylor at Hayfield nr Maprik (East Sepik Prov., Papua New Guinea). (Kohout 2006)

This taxon was described from New Guinea.
