Cardiocondyla shuckardi sculptinodis Santschi 1913 Revived Combination 

Cardiocondyla shuckardi Forel st. sculptinodis Santschi 1913: 305 View Cited Treatment   . Holotype gyne: Madagascar [ NHMBAbout NHMB, antweb.org image of specimen CASENT0101127] (examined). Subspecies of C. shuckardi: Wheeler 1922: 1021  . Subspecies of C. nuda: Emery 1922: 126  . 

The type gyne has no head but the conserved mesosoma and waist characters clearly exclude that it from the C. nuda  group. Comparisons were made with 114 gynes of C. nuda  , C. mauritanica  , C. atalanta  , C. kagutsuchi  , and C. itsukii  and NUMOBAT files of these specimens hosted in SMNAbout SMN Görlitz. The C. sculptinodis  type differs from this C. nuda  group material by a wide petiole with a node appearing globular in dorsal view and a ratio PEW/PPW of 0.68. This ratio is 0.576 ± 0.027 [0.511, 0.654] in 114 measured gynes of the C. nuda  group— in other words, the C. sculptinodis  type has a probability of p<0.00005 of belonging to this cluster. Furthermore , the propodeum of the C. sculptinodis  type shows in lateral view spines reduced to a blunt angle of 125°. The spines of the C. nuda  group gynes are developed as more or less sharp dents the upper and lower margins of which form an angle of 75 – 95°. Thirdly , the color of the C. sculptinodis  type is uniformly dark or blackish brown— this has never been observed in the two species of the C. nuda  group possibly occurring in Madagascar ( C. mauritanica  and C. itsukii  ). On the other hand, there is no single character of the C. sculptinodis  type which contradicts an allocation to the C. shuckardi  group. The character combination is close to C. shuckardi Forel 1891  itself, the type of which is also from Madagascar  . The C. shuckardi  group contains a minimum of four and a maximum of six species (unpub. data). It is not clear if there is more than one species of this group on Madagascar, so synonymization at this point would be premature.
