Cardiocondyla goa

This species is known from the type material (3 workers and a queen). Nothing is known about its biology.

Identification
Seifert (2003) - A member of the Cardiocondyla minutior group. The most eye-catching difference of C. goa in comparison to the cosmopolitan Cardiocondyla minutior is the darker pigmention: the sum of head and mesosoma pigmentation score PigCap + PigMes is 14.9 ± 2.9 [10, 20] in 45 C. minutior workers and 23.2 ± 1.0 [22, 24] in 4 workers of C. goa, i.e. even the dark morph of C. minutior is still lighter than the blackish brown C. goa. Cardiocondyla goa has a longer scape, a shorter head, shorter tergite pubescence, and a narrower frons, spine base, and postpetiole.

Worker
Small size, CS 420. Head elongated, CL/CW 1.225. Postocular distance very large, PoOC/CL 0.476. Scape longer than in related species, SL/CS 0.775. Eye rather small, EYE 0.228; with notable microsetae, the longest 6 - 7 mm long. Occipital margin straight. Frontal carinae slightly converging immediately caudal of FRS level or parallele. Anterior clypeal margin in median third straight. Posterior area of clypeus and a narrow anteromedian stripe on vertex longitudinally carinulate. Frontal laminae with few foveolae and few longitudinal rugulae. Paramedian area of vertex with deeply impressed and densely arranged, flat-bottomed foveolae of 15 - 17 mm diameter; foveolae with inner corona (margin of flat tubercle) of 7 - 8 mm diameter. Dorsal area of promesonotum irregularly foveolate-microrugulose, dorsolaterally with fragmentaric longitudinal rugae. Propodeum and whole lateral area of mesosoma strongly microreticulate, inter- and infraspinal area of propodeum more shining, more finely microreticulate-rugulose; 2 longitudinal curved rugae on metapleural gland bulla. Waist segments strongly microreticulate (on dorsum of nodes weakly); both segments in dorsal view and at lower magnifications appearing gently shining. First gaster tergite shining, with very fine microreticulum. Pubescence on whole body long and dense, sqrtPDG 3.49. Dorsal mesosoma profile slightly convex or straight, metanotal groove entirely absent, a very shallow mesopropodeal concavity individually present. Spines short and acute, their axis in profile deviating by 40 - 45° from longitudinal axis of mesosoma. Spine bases more approached than in Cardiocondyla minutior. Petiole in profile with concave anterior face and rounded node that is in dorsal view circular. Postpetiole very low, its sternite completely flat, without any anteroventral bulge; in dorsal view with convex sides and straight or slightly convex anterior margin. Head and mesosoma very dark to blackish brown, waist segments in one specimen lighter, gaster blackish brown.

Queen
Very small size. Head elongated, CL/CW 1.220. Scape short, SL/CS 0.739. Postocular index very large, PoOclCL 0.463. Eyes with numerous hairs, the longest 8 - 11 mm long. Occipital and anteromedian clypeal margin more or less straight. Vertex with deeply impressed, flat-bottomed, densely-packed foveolae of 14 - 16 mm diameter; foveolae showing an inner corona of 7 - 9 mm diameter. Median area of vertex with few longitudinal rugae. Frontal laminae and clypeus longitudinally carinulate-rugulose. Whole dorsal area of mesosoma with deep, densely-packed foveolae; median area of mesonotum with 3 - 4 longitudinal rugulae. Lateral area of mesosoma foveolate-reticulate, lateral area of metapleuron with longitudinal rugae. Propodeal spines shorter than in Cardiocondyla minutior, their axis deviating from mesosomal axis in lateral view by 30°. Petiole node foveolate-reticulate, in dorsal view circular. Postpetiole in dorsal view more strongly foveolate-reticulate, distinctly wider than long, with straight anterior margin and strongly convex sides. Postpetiolar sternite very flat, without any bulge. Whole body covered by dense pubescence that is shorter than in C. minutior. Dorsum of gaster shining, but with fine microreticulum. Whole body blackish brown, appendages lighter.
