Queens control caste allocation in the ant Cardiocondyla obscurior
<p>Social insect queens and workers can engage in conflict over reproductive allocation when they have different fitness optima. Here, we show that queens have control over queen-worker caste allocation in the ant <em>Cardiocondyla</em> <em>obscurior</em>, a species in which workers lack reproductive organs. We describe crystalline deposits that distinguish castes from the egg stage onwards, providing the first report of a discrete trait that can be used to identify ant caste throughout pre-imaginal development. Comparison of queen- and worker-destined eggs and larvae revealed size and weight differences in late development, but no discernible differences in traits that may be used in social interactions, including hair morphology and cuticular odors. In line with a lack of caste-specific traits, adult workers treated developing queens and workers indiscriminately. Together with previous studies demonstrating queen control over sex allocation, these results show that queens control reproductive allocation in <em>C. obscurior</em> and suggest that the fitness interests of colony members are aligned to optimise resource allocation in this ant.</p>

FIGURE 9. Phylogenetic tree estimated from a 871 in A taxonomic revision of the Cardiocondyla nuda group (Hymenoptera: Formicidae)
FIGURE 9. Phylogenetic tree estimated from a 871bp fragment of CO I / CO using MrBayes version 3.2.2 with GTR+G+I as model for gene evolution. Bayesian posterior probabilities given as percentages at the nodes. Using two samples of the Cardiocondyla elegans species complex as outgroup, mtDNA shows a strong separation of the C. nuda species group into two major clades containing four species of the C. mauritanica species complex and three species of the C. nuda species complex. The disagreement between the species identification based on morphology and the mtDNA tree is here 3.8%.
FIGURE 8 in A taxonomic revision of the Cardiocondyla nuda group (Hymenoptera: Formicidae)
FIGURE 8. NC-Ward clustering of 61 samples of the two remaining Cardiocondyla nuda species complex after C. nuda has been removed from analysis. The lower of the two main branches belongs to C. atalanta Forel, the upper one to C. paranuda. The left column of bars indicates the final clustering hypothesis for K=2 (C. atalanta vs. C. paranuda) determined by a controlling linear discriminant function (LDA), and the right column of bars the classification by non-hierarchical NC-K- Means clustering. The classification errors in in NC-Ward and NC-K-Means are both 3.3%.

FIGURE 7 in A taxonomic revision of the Cardiocondyla nuda group (Hymenoptera: Formicidae)
FIGURE 7. NC-Ward clustering of 100 samples of the Cardiocondyla nuda species complex. The lower of the two main branches belongs to C. nuda (Mayr), the upper one to the three remaining species of the complex. The left column of bars indicates the final clustering hypothesis for K=2 (C. nuda vs. not C. nuda) determined by a controlling linear discriminant function (LDA), and the right column of bars the classification by non-hierarchical NC-K-Means clustering. The classification errors in in NC-Ward and NC-K-Means are 1.0% and 2.0% respectively.
