Cardiocondyla semirubra

Known only from the type workers, nothing is known about the biology of .

Identification
Seifert (2003) - The C. semirubra worker differs from Cardiocondyla batesii, Cardiocondyla kushanica, and Cardiocondyla bicoronata in particular by its unusually massive petiole that is almost as wide as high. C. semirubra differs from Cardiocondyla brachyceps by longer head, shorter scape, much smaller PLG, much shorter petiolar peduncle, and characteristic colour pattern.

Worker
Head moderately long, CL/CW 1.168. Postocular index very small, PoOc/CL 0.374. Occipital margin slightly concave. Scape short, SL/CS 0.782. Eyes relatively large, EYE 0.256. Frontal carinae immediately posterior of FRS level slightly converging. Lateral and paramedian area of clypeus, frontal laminae, and area posterior of frontal laminae finely longitudinally carinulate. A small stripe on median area of vertex often glabrous. Foveolae on vertex shallow, with weak inner corona and 16 - 19 mm diameter; interspaces shining, slightly wider than foveolar diameter, and with fine, scattered, simple or cross-branched carinulae. Mesosoma moderately shining, finely microreticulate. Median area of promesonotum finely longitudinally carinulate-rugulose. Lateral area of meso- and metapleuron finely longitudinally carinulate-rugulose. Metanotal furrow rather deep. Petiole profile with short anterior peduncle, ample node and, compared to Cardiocondyla batesii, with more concave anterior face and node not produced caudad. Petiole node in dorsal view gradually merging with a rather short anterior peduncle; much wider than in related species (PEW/CS 0.322). Postpetiolar sternite without any flat bulge. Dorsal head, gaster, coxae, femora, and tibiae dark to blackish brown; mesosoma and petiole reddish brown; postpetiole, scape, and antennal club dark brown.
