Cardiocondyla parvinoda

Nothing is known concerning the biology of this species.

Identification
Seifert (2022) - Worker: By far the largest species of the C. 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.

Distribution
So far known only from the north of the Oriental region between 14 and 23°N and 73 and 121°E. It was found from the lowlands up to about 1300 m. (Seifert, 2022)

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
