Specimen Labels

Known only from the holotype worker, nothing is known about the biology of Cardiocondyla unicalis.


Seifert (2003) - A member of the Cardiocondyla shuckardi group. The unique combination of rare characters justifies the description of C. unicalis, based upon a single specimen. These characters are extremely small eyes, very narrow postpetiole, very short head, large size, the long scape, slender mesosoma with a deep metanotal impression, and reduced spines. The next similar species is Cardiocondyla fajumensis, from which it differs by the extremely small CL/CW, being fully outside the expected range of variation in C. fajumensis. Further differences to C. fajumensis are the weaker sculpture, the smaller eyes, the shorter scape, and the darker colour.

holotype: CS 610, CL/CW l.126, SL/CS 0.837, PoOc/CL 0.451, EYE 0.199, dFOV 19.0, FRS/CS 0.270, SPBA/CS 0.250, SP/CS 0.051, PEW/CS 0.272, PPW/CS 0.411, PEH/CS 0.290, PPH/CS 0.278, PEW/PPW 0.661, sqrtPDG 4.01, PLG/CS 4.75 %, MGr/CS 4.92 %.

Large, CS 610. Head extremely short, CL/CW 1.126. Postocular distance large, PoOc/CL 0.45l. Scape long, SL/CS 0.837. Eyes extremely small (EYE 0.199), with very few microsetae of 4 - 6 mm length. Occipital margin straight. Sculpture on head, mesosoma and waist much weaker than in Cardiocondyla fajumensis. Foveolae on paramedian area of vertex shallow, but rather large (dFov 19 mm), frequently bicoronate, with irregular margins; interspaces between foveolae usually present but much narrower than foveolar diameter. Median and paramedian areas of vertex and frontal laminae longitudinally carinulate. Clypeus with few weak longitudinal rugae. Frontal carinae immediately behind FRS level slightly converging, FL/FR 1.101. Dorsal area of promesonotum, lateral area of pronotum, and waist glabrous; dorsal area of propodeum shining but with shallow microreticulum; lateral area of mesonotum, mesopleuron, lateral area of propodeum, and metapleuron more deeply microreticulate. Metapleuron additionally with 3 longitudinal rugae. Mesosoma slender and with deep metanotal impression. Spines reduced to blunt corners. Petiole node as long as wide and circular in dorsal view. Postpetiole very narrow (PPW/CS 0.411), its sternite with 2 suggested paramedian carinae. Head and gaster dark brown, mesosoma and waist medium brown.
