Identification
Seifert (2022) - A member of the Cardiocondyla wheeleri group. Worker: Medium-sized, CS 515 µm. Head rather long (CL/CW 1.152); with head adjusted in measuring position for CL, its posterior margin straight and median third of anterior clypeal margin only very feebly concave; the maximum depth of clypeal concavity is only 1.0–2.1% CL. Postocular distance large, PoOc/CL 0.446. Scape long, SL/CS 0.870. Eye small, EYE/CS 0.220. Frons rather narrow (FRS/CS 0.287), frontal carinae immediately caudal of the FRS level slightly converging (FL/FR 1.023). Metanotal depression moderately deep and with shallow slopes (MGR/CS 2.68%), dorsal profile of promesonotum and propodeum convex. Pronotal corners in dorsal view prominent, but blunt and forming an angle of 90–100°. Dorsal plane of mesosoma rather continuously narrowing from pronotal corners caudal to metanotal groove; there is only a weak convexity at the mesonotal level. Propodeal spines strong and extremely long (SP/CS 0.404), with a very large basal distance(SPBA/CS 0.366), in lateral view down-curved and their average orientation almost parallel to longitudinal mesosomal axis. Petiole rather high (PeH/CS 0.344); in lateral view with a very short peduncle, a weakly concave frontal and broadly convex dorsal profile, in dorsal view moderately wide (PeW/CS 0.284) and its node longer than wide. Postpetiole in dorsal view broad (PpW/CS 0.557), with semicircularly rounded sides and clearly excavated anterior margin, in lateral view much lower than petiole (PpH/CS 0.273), its sternite shallowly convex and without any prominent structures. Central vertex finely longitudinally carinulate-rugulose; paramedian and lateral vertex longitudinally rugulose-foveolate, foveolae rather shallow, often bicoronate, not eye-catching, with 18–20 µm diameter, interspaces wider than foveolar diameter. All interspaces between microsculptural elements on dorsal head including frontal laminae and clypeus perfectly matt (but surfaces are polluted, so perhaps in clean condition slightly shiny?). Mesosoma matt, entirely microreticulate-corrugated. Petiole rather matt, microreticulate. Postpetiole in dorsal view moderately shiny and finely microreticulate. Gaster tergites moderately shiny, with a fine microreticulum (which are really the margins of clinker-like surface structures. Tergite pubescence short and dilute (PLG/CS 4.44%, sqPDG 5.71). Whole body except of the dark brown gaster and the infuscated antennal club yellowish.

Type Material
This taxon was described from the Rawlinson Mountains in Papua New Guinea. Investigated were 2 syntype workers labelled by H.Stitz “D.N.Guinea. Rawlinsongeb. Coll. Viehm.“ and “Cardiocondyla wheeleri Viehm”, ZM Berlin. (Seifert, 2022)
Description
Species redescribed in diagnosis, Seifert 2022 (see the identification section, above, of this species page). Cardiocondyla species treated in this revision are differentiated using exploratory data analyses and principle component analysis (Numeric Morphology-Based Alpha-Taxonomy/NUMOBAT) of worker measurements (Table S1 and S2, Seifert 2022 supplementary information).
