Identification
Seifert (2022) - Worker: By far the largest species of the Cardiocondyla minutior group, CS 501 µm. Head comparatively short CL/CW 1.182. Postocular distance rather small, PoOc/CL 0.468. Scape much longer than in most species of the C. minutior group, SL/CS 0.831. Eyes small and with numerous micropilae of 13 µm maximum length, EYE/CS 0.219. Occipital margin straight. Anterior clypeal margin concave, clypeal sides each with 2–3 longitudinal rugae or costae that are stronger than in other species. Frons rather wide FRS/CS 0.241 and frontal carinae more diverging frontad than in related species, FL/FR 1.122. Dorsal profile of mesosoma rather straight, metanotal depression absent or weak MGr/CS 1.25%. Spines triangular and sharp, the axis in lateral view deviating from longitudinal axis of mesosoma by about 50°, SP/CS 0.124; spine bases more approached, SPBA/CS 0.263. Petiole rather low and narrow (PeH/CS 0.305, PeW/CS 0.256), with a rather long peduncle, dorsal node profile convex with a straight central portion. Postpetiole narrower than in any related species (PpW/CS 0.402) and extremely low (PpH/CS 0.230); postpetiolar sternite completely flat, without any prominent structures. Frontal laminae and anteromedian vertex longitudinally carinulate. Lateral vertex with deeply impressed, densely-packed, circular foveolae of 19–20 µm mean diameter which show a inner corona of 9–11 µm diameter. Dorsal mesosoma very shiny, but with scattered and shallow foveolae and fine irregular rugosity. Lateral mesonotum and lateral propodeum longitudinally carinulate. Meso- and metapleurae more strongly and densely longitudinally carinulate-rugulose. Both waist segments glabrous except for small hair base pits. Tergite pubescence long and rather dense, PLG/CS 8.08, sqPDG 3.62. Color variable. Dorsal head yellowish brown to dark brown; mesosoma and petiole yellow, yellowish brown or dark brown; postpetiole slightly darker; gaster dark brown.
With exception of its larger size Cardiocondyla parvinoda shows any character typical for the C. minutior group. The combination of extremely small postpetiole measurements with a moderately elongated head, short spines and the shiny dorsal mesosoma allows a separation from any known species worldwide.

Type Material
The taxon has been described from Poona / India. Investigated by Seifert (2022) were 2 syntype workers labelled “C. parvinoda, Forel type, Poona (Wroughton) XXIII/13”, MHN Genève; 1 syntype worker labelled “C. parvinoda, type Forel, Poona XXIII/13 (Wroughton)”, NHM Basel. 1 worker syntype labelled “Poona, Wroughton, C. parvinoda Forel type”, NHM Wien. 1 worker syntype labelled by Stitz “Paona, Wroughton” and “Cardiocondyla parvinoda For.”, ZM Berlin.
Description
Worker
Bingham (1903): Resembles C. nuda Mayr, but the head, thorax and pedicel are of a lighter duller red, the antenna; and legs a paler shade of the same, and the abdomen shining castaneous. Head broader, with a distinct posterior margin; thorax and legs as in C. nuda; pedicel of the abdomen proportionately not so long, with the 1st node higher; the 2nd node much narrower, being as long as broad and not twice as broad as the 1st node; abdomen as in C. nuda.
Length: 2 - 2.2 mm
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).
